The tegmentum is involved in many unconscious homeostatic and reflexive pathways, and is the motor center that relays inhibitory signals to the thalamus and basal nuclei to prevent unwanted body movement. It extends from the substantia nigra to the cerebral aqueduct (also called the ventricular mesocoeli).

What is the main function of the tegmentum?

Tegmentum. Reticular formation: This highly diverse and integrative area contains a network of nuclei responsible for many vital functions including arousal, consciousness, sleep-wake cycles, coordination of certain movements, and cardiovascular control.

Is the tegmentum in the midbrain?

structure of the midbrain

consists of two parts: the tegmentum, a phylogenetically older part that contains the reticular formation, and the pontine nuclei, a larger part composed of masses of neurons that lie among large bundles of longitudinal and transverse nerve fibres.
