Posterolateral central arteries

Posterolateral central arteries (also posterolateral perforating arteries, or posterolateral ganglionic arteries) are arteries that arise from the posterior cerebral artery distal to its first - pre-communicating (P1) -segment (i.e. distal to the origin of the posterior communicating artery).

They are distributed to the:


 * (lateral part of ) cerebral peduncle
 * tectum
 * corpora quadrigemina (i.e. superior and inferior colliculi)
 * pineal gland
 * (via the thalamogeniculate arteries ) (the posterior parts of) thalamus
 * medial geniculate nucleus
 * lateral geniculate nucleus
 * ventral lateral nucleus of thalamus
