Generic Body Lateral

The geniculate bodies (lat. Corpus geniculatum) are two formations of the hemispheres of the telencephalon, bordering the posterior part of the internal capsule and the medulla oblongata. Most studies are devoted to their characterization not as structural and anatomical formations, but as receptor fields of the visual system (visual nuclei). The geniculate bodies have a paired structure: each of them is located within the lateral border of the midbrain and covers the head of the optic nerve. They are compact structures bounded at the upper pole by the corpus callosum and at the lower pole by the corpus dentate. The anterior, most convex edge of the geniculate bodies is limited by a transparent septum. Inside its layer, each N.k.t. has a body and two protrusions (clusters of nerve cells) - the outer and inner geniculate nucleus. In the thin bundle of long cone-shaped cells of the first of them, rod-shaped processes of peripheral neurons are visible, to which nerve impulses are sent from the photoreceptors of the retina. In the internal geniculate nucleus, excitation switches from one type of peripheral cell to another, corresponding to monochrome vision (including color vision). on his
