There are two main cell types in the ventral subnucleus of the medial geniculate body (VMGN): Thalamocortical relay cells (or principal neurons): The dendritic input to these cells comes from two sets of dendritic trees oriented on opposite poles of the cell. The long axis of the relay cells lie parallel to each other running superior ...
This traditional list does not accord strictly with human thalamic anatomy. Nuclear groups of the thalamus include: anterior nuclear group [1] (anteroventral, [2] anterodorsal, [3] anteromedial [4]) medial nuclear group (medial dorsal nucleus, [5] a.k.a. dorsomedial) parvocellular part [6] (a.k.a. parvicellular part) magnocellular part [7]
Medial superior genicular artery; Lateral superior genicular artery; The middle genicular artery is a small branch of the popliteal artery that originates inferior or distal to both the superior genicular arteries as well as the sural arteries.
According to the 42th Edition of Gray's Anatomy, the thalamogeniculate arteries supply the posterior thalamus, and medial geniculate nucleus. [2] According to the Medical Dictionary of the French Academy of Medicine, it supplies the ventral lateral nucleus of thalamus, and the geniculate nuclei. [1]
Occupying the posterior part of the commissure of the optic chiasma is a strand of fibers, the Ventral supraoptic decussation (commissure of Gudden, Gudden's inferior commissure), which is not derived from the optic nerves; it forms a connecting link between the medial geniculate bodies.
[1] [2] This point of origin is distal to the superior genicular arteries, and between, equidistantly, the medial condyle of femur and the lateral condyle of femur. [2] As a normal variation, the MGA may emerge from the popliteal artery at a common point of origin shared with the superior lateral genicular artery , or both vessels may arise at ...
