The basal nuclei
The basal nuclei subcortical, intracerebral masses of gray matter forming important parts of the extrapyramidal system. They include: 1) the corpus striatum; 2) the claustrum and; 3) the amygdaloid body 1. The corpus striatum , or "striped body" consists of the caudate nucleus, núcleus caudátus and the lenticular nucleus, núcleus lentifórmis Because the internal capsule runs between the caudate and lenticular nucleus of the basal ganglia, the group of structures looks striped. The caudate nucleus is a comma-shaped structure which lies medially from the lenticular nucleus. The nucleus has a head, a body and a tail The head , cáput nuclei caudati forms the lateral wall of the anterior horn of the lateral ventricle . Anteriorly it adjoins the substantia perforata anterior . The body , corpus nuclei caudati, forms the floor of the central part of the lateral ventricle The t
