The epithalamus makes up the posterior portion of the diencephalon and consists of multiple structures including the habenula, the stria medullaris, and the pineal gland. The labia majora are thicker anteriorly where they join to form the ‘anterior commissure.’ In the nulliparous woman, they merge posteriorly to form a ridge, ‘the posterior commissure,’ which overlies the perineal body. 1,812 Likes, 63 Comments - Mitch Herbert (@mitchmherbert) on Instagram: “Excited to start this journey! It classically causes the triad of upward gaze palsy (often manifesting as diplopia), pupillary light-near dissociation (the pupil is poorly reac-tive to light but constricts with convergence), and convergence-retraction nystagmus (1,6). The midbrain connects the pons and cerebellum with the forebrain and can be divided into a ventral part, the tegmentum, and a dorsal part, the tectal or quadrigeminal plate (Figs 2, 3). The dorsal column–medial lemniscus pathway (DCML) (also known as the posterior column-medial lemniscus pathway, PCML) is a sensory pathway of the central nervous system that conveys sensations of fine touch, vibration, two-point discrimination, and proprioception (position) from the skin and joints. Septum pellucdium Corpus Callosum Fornix Anterior Commissure.

Technique to localize it: Use the axial orientation ; It is a fiber tract similar to the anterior commissure, but a few centimeters more posterior. Much processing of lower-level assessment and movement control is carried out by all these connections, giving the arm movement system a very large number of degrees of freedom [ 42 ]. The medulla contains mostly white matter that carries nerve signals ascending into the brain and descending into the spinal cord. Glycine has a similar inhibitory action in the posterior parts of the brain.
