The brachium of superior colliculus (or superior brachium) is a branch that extends laterally from the superior colliculus, and, passing to the thalamus between the pulvinar and the medial geniculate nuclei, is partly continued into an eminence called the lateral geniculate nucleus, and partly into the optic tract.

Primary lateral sclerosis, progressive muscle weakness in the voluntary muscles. Primary sclerosing cholangitis, a hardening of the bile duct by scarring and repeated inflammation. Systemic sclerosis (progressive systemic scleroderma), a rare, chronic disease which affects the skin, and in some cases also blood vessels and internal organs.
Quadrigeminal brachium may refer to: Inferior colliculus, also known by the Latin term inferior quadrigeminal brachium; Superior colliculus, ...
Primary lateral sclerosis (PLS) usually presents with gradual-onset, progressive, lower-extremity stiffness and pain due to muscle spasticity. Onset is often asymmetrical. [ 2 ] Although the muscles do not appear to atrophy as in ALS (at least initially), the disabling aspect of PLS is muscle spasticity and cramping, and intense pain when those ...
It then gives off branches to supply quadrigeminal plate and the adjacent structures in the midbrain. The origin of this artery is proximal to the origin of medial and lateral posterior choroidal branch of the posterior cerebral artery. The main collicular artery also gives branch to an accessory collicular artery.
It consists of groups of nerve cells-grey matter scattered in white matter. It basically connects the forebrain and the hind brain. It has four corpora quadrigemina which are the reflex centres of eye movement and auditory responses. The superior part of corpora quadrigemina are called superior colliculi, and inferior part as inferior colliculi ...
Amyotrophic lateral sclerosis (ALS), also known as motor neurone disease (MND) or (in the United States) Lou Gehrig's disease (LGD), is a rare, terminal neurodegenerative disorder that results in the progressive loss of both upper and lower motor neurons that normally control voluntary muscle contraction.

Subacute combined degeneration of spinal cord, also known as myelosis funiculus, or funicular myelosis, [1] also Lichtheim's disease, [2] [3] and Putnam-Dana syndrome, [4] refers to degeneration of the posterior and lateral columns of the spinal cord as a result of vitamin B 12 deficiency (most common).
