Tegmentum

From WikiMD's Wellnesspedia

Tegmentum is a part of the midbrain, located between the ventricular surface and the substantia nigra. It is involved in many unconscious homeostatic and reflexive pathways, and is the motor center that relays inhibitory signals to the thalamus and basal nuclei preventing unwanted body movement.

Anatomy[edit | edit source]

The tegmentum is the ventral part of the midbrain and includes the periaqueductal gray, reticular formation, red nucleus, and substantia nigra. It is separated from the cerebral peduncle by the substantia nigra and crus cerebri.

Function[edit | edit source]

The tegmentum plays a role in many functions, including motor function regulation, relaying inhibitory signals to the thalamus and basal nuclei, and involvement in reflexive eye movements. It also plays a role in the regulation of awareness and consciousness.

Clinical significance[edit | edit source]

Damage to the tegmentum can result in a variety of neurological disorders, including Parkinson's disease, Huntington's disease, and Wilson's disease. It can also be affected in conditions such as schizophrenia and depression.
