 * Endocrine System: (link)
 * I have chosen to evaluate this article as it is    considered an important topic; however, has a C-rank. This article could     be a source of relevant, important information to many individuals seeking     information on the endocrine system and associated disorders.

Lead

The endocrine system is a chemical messenger system comprising feedback loops of the hormones released by internal glands of an organism directly into the circulatory system, regulating distant target organs. In humans, the major endocrine glands are the thyroid gland and the adrenal glands. In vertebrates, the hypothalamus is the neural control center for all endocrine systems. The study of the endocrine system and its disorders is known as endocrinology. Endocrinology is a branch of internal medicine.


 * The introductory sentence gives a general overview of    the topic being discussed. I do believe this opening paragraph is vague,     and some of the information is not relevant and could be expanded upon.     The thyroid gland and adrenal gland, as correctly stated, are major     endocrine glands; however, there are many others. This should be     referenced in this opening paragraph. Additionally, the shift in the     opening paragraph from humans to vertebrates as a whole is confusing;     could this be included as a subsection later on if deemed relevant? The     organization of this section could be improved by focusing on one (i.e.     humans) or the other (i.e. all vertebrates).
 * No. There are many other subsections within the article    not eluded too. The largest subsection included in the article is     "Disease". There is no indication that the author intended to     cover endocrine diseases and their relevance based on the lead section.
 * The article does cover what is discussed in this    "lead" paragraph. The coverage is minimal.
 * The lead is lacking detail and some of the included    information was not expanded upon, or it is not relevant to the focus of     the paper. "Endocrinology is a branch of internal medicine." is     vague and does not fit in the section with previous information.
 * The lead section should be more encompassing of the    following subsections of the article: signaling pathways, diseases, other     animals.

Content

Diseases of the endocrine system are common, including conditions such as diabetes mellitus, thyroid disease, and obesity. Endocrine disease is characterized by misregulated hormone release (a productive pituitary adenoma), inappropriate response to signaling (hypothyroidism), lack of a gland (diabetes mellitus type 1, diminished erythropoiesis in chronic kidney failure), or structural enlargement in a critical site such as the thyroid (toxic multinodular goitre). Hypofunction of endocrine glands can occur as a result of loss of reserve, hyposecretion, agenesis, atrophy, or active destruction. Hyperfunction can occur as a result of hypersecretion, loss of suppression, hyperplastic or neoplastic change, or hyperstimulation.

Endocrinopathies are classified as primary, secondary, or tertiary. Primary endocrine disease inhibits the action of downstream glands. Secondary endocrine disease is indicative of a problem with the pituitary gland. Tertiary endocrine disease is associated with dysfunction of the hypothalamus and its releasing hormones.

As the thyroid, and hormones have been implicated in signaling distant tissues to proliferate, for example, the estrogen receptor has been shown to be involved in certain breast cancers. Endocrine, paracrine, and autocrine signaling have all been implicated in proliferation, one of the required steps of oncogenesis.

Other common diseases that result from endocrine dysfunction include Addison's disease, Cushing's disease and Graves' disease. Cushing's disease and Addison's disease are pathologies involving the dysfunction of the adrenal gland. Dysfunction in the adrenal gland could be due to primary or secondary factors and can result in hypercortisolism or hypocortisolism. Cushing's disease is characterized by the hypersecretion of the adrenocorticotropic hormone (ACTH) due to a pituitary adenoma that ultimately causes endogenous hypercortisolism by stimulating the adrenal glands. Some clinical signs of Cushing's disease include obesity, moon face, and hirsutism. Addison's disease is an endocrine disease that results from hypocortisolism caused by adrenal gland insufficiency. Adrenal insufficiency is significant because it is correlated with decreased ability to maintain blood pressure and blood sugar, a defect that can prove to be fatal.

Graves' disease involves the hyperactivity of the thyroid gland which produces the T3 and T4 hormones. Graves' disease effects range from excess sweating, fatigue, heat intolerance and high blood pressure to swelling of the eyes that causes redness, puffiness and in rare cases reduced or double vision.


 * This content is very relevant to the topic of the    endocrine system as there are many manifestations to disease related to     this system. This was not discussed in the lead section which would be an     important indicator.
 * The content is up-to-date in the context of current    understanding on the etiologies of disease mentioned.
 * I believe there is a lot of content missing. This    section primarily focuses on thyroid disorders. Although a major component     of endocrine disease, it is not all encompassing. Organization could be     improved if the author wished to focus on subsections. For example, a     discussion and explanation of hypothyroidism and hyperthyroidism could be     included with associated diseases and etiology mentioned. Additionally,     due to the mention of "major endocrine systems" earlier in the     article, adding an example of disease for each would be appropriate. No     mention of T1D in reference to insulin is included in the section. No     discussion of sex hormones or associated disease is included. There is a lot     of missing information in this section that would be relevant to the     discussion of endocrine disorders. Although it would be impossible to     include every endocrine disorder known, it would be relevant to include     one manifestation of disease for each "major endocrine system"     that was included in the previous section.
 * This article includes no mention in equity gaps. It is    known that endocrine disorders are more likely to effect women than men;     this would be relevant information to include in the article under the     "Disease" subsection.

The included content is poor. There is no analysis of text by the author for edit because in most sections, there are none. Most sections are characterized by links to other sites that explain much of the content being referred to. The author could have included ready-to-read information in these sections. The content of the article needs work in terms of further explanation of valuable content and summaries to the link provided for additional information. The content section is bare. Some information is included in the author's own words, nut this could be a source of significant improvement for the article to receive a better Wikipedia rating, specifically because of it's importance.

Tone and Balance


 * The author provided an unbiased approach to the    article.

Sources and References

Guiding questions


 * The author of the article did include secondary    sources, however, some of the articles used for reference are linked back     to primary research articles (inappropriate for Wikipedia).
 * The sources are thorough. They provide a significant amount    of information about endocrinology, the etiology of disease, and cellular     mechanics involved. From looking at the articles, however, they were not     utilized in their greatest capacity for the article posted on Wikipedia.     It seems a lot of relevant information in these sources was overlooked and     overgeneralized.
 * Most of the articles / sources are at least 10+ years    old. This could lead to discrepancies of new literature on the topic. Most     recent sources should be included for these pages so they are more up-to-date.
 * It does seem that the articles are written by a diverse    background of authors.
 * Some of the links work, however, many include ISBN or    DOI numbers that do not directly link to the sources used for the article.

Organization

Guiding questions


 * The writing of the article needs improvement; it is a    mix of good writing and writing that needs work. For example, I think the     author did a good job of explaining hormones and how they work within the     body. In other cases, however, there are descriptions (i.e. cells types, major     endocrine systems, and disease) that need reorganization and better     description. If I were to read this article without a background in     science and anatomy, I do not think I could read this article without     having to do a significant amount of additional research to understand the     topics discussed.
 * This article does contain grammatical errors.
 * The article is broken down into important sections; there    could be additional subsections added (discussing the “major endocrine     systems”, diseases) and reorganized for better flow on topics. The content     within the sections is not great. Further explanation and additional     sections added would vastly improve this article.

Images and Media

Guiding questions


 * There are included images of the endocrine system and how    it differs among men and women. The images are not provided in content     within the article, however. Additionally, there is an image about endocrine     disorders across the world and their prevalence. This is not discussed in     the article at all, and it is not relevant to the content that is included     within the article.
 * The images are well-captioned in terms of indicating    the information within the images.
 * I do not believe that these images follow Wikipedia’s Copyright    rules. The links in the image are those already included in the original     author’s image. No external links are provided to the images.
 * The images are laid out in a visually appealing way; some    do not seem relevant, however, and their role is not exactly clear based     on provided information in the text.

Checking the talk page

Guiding questions


 * Some of the comments on the Talk Page are referencing    increased descriptions on different topics rather than just supplying a     link with no content, and a suggested expansion on the disease section. Some     previous edits have been in terms of contextual sentences within the subsections     provided.
 * This article is considered a C-Class article. It does    not appear that it is apart of any Wikiprojects.
 * It seems that we have talked about it similar, however,    this article is far less informative and in-depth. It provides the “bare-minimum”     of information and does not go into depth very much.

Overall impressions

Guiding questions


 * The overall status is that of moderate strength. I do    feel that the sections included make sense, they are relevant and     important to the topic, and would be important in understanding     endocrinology. The sections, however, are not are contextual advanced as     they could / should be. More information would be important, such as     further description on topics and relevant images.
 * The article is strong in that it provides a good    overall description of “endocrinology”. The author identified important     subsections that are relevant to endocrinology. The “major endocrine     systems” were all identified and important cellular subtypes were included     as well. The backbone of the article is strong and is well-developed.
 * The article can be improved by adding more information    and relevant images. An image showing autocrine function or hormone effect     on a cell would be beneficial. The contextual information is lacking. The     only section with actual written information is the “disease” section. It     seems that there was not a lot of effort in terms of developing this     article as it is seriously lacking information. The ideas are not entirely     well-rounded. The sections could be very important to the topic as a whole     if there is more information provided with a description of its relevance     to the topic of Endocrinology.
 * The article overall seems both poorly developed and    underdeveloped (for the reasons stated above).
