and the fourth ventricle. It consists of the medullary tegmentum, the pontine tegmentum, and the midbrain tegmentum.

Where is the tegmentum located in the brain?

The tegmentum (from Latin for "covering") is a general area within the brainstem. The tegmentum is the ventral part of the midbrain and the tectum is the dorsal part of the midbrain. It is located between the ventricular system and distinctive basal or ventral structures at each level.

Is the tegmentum part of the brainstem?

The tegmentum is one of the areas of the brainstem. It is a phylogenetically old part of the brainstem and, in adults, is the location of the brainstem nuclei. In the midbrain, it sits between the quadrigeminal plate and cerebral peduncles.
