What is the 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.

What structures are located in the tegmentum?

Structures included in the midbrain tegmentum include the red nucleus, reticular formation, and substantia nigra. The red nucleus is responsible for controlling basic body and limb movements. The reticular formation controls arousal and self-consciousness, and the [substantia nigra] integrates voluntary movements.

What does the tegmentum contain?

The tegmentum of the medulla contains the medullary reticular formation, together with cranial nerve nuclei and ascending tracts. It also includes a number of ‘vital centres’ which subserve cardiorespiratory functions and airway-protective reflexes (e.g. cough, sneeze, gag).

What is the tectum and tegmentum?

The region of the midbrain posterior to the cerebral aqueduct is called the tectum, which means “roof” in Latin. The tectum consists primarily of the superior and inferior colliculi. The area of the midbrain anterior to, or in front of, the cerebral aqueduct is called the tegmentum.

What is a tegmentum?

Definition of tegmentum : an anatomical covering : tegmen especially : the part of the ventral midbrain above the substantia nigra formed of longitudinal white fibers with arched transverse fibers and gray matter.

What is meant by tegmentum?

Is the tegmentum part of the pons?

The pontine tegmentum, or dorsal pons, is located within the brainstem, and is one of two parts of the pons, the other being the ventral pons or basilar part of the pons.

Is the tegmentum in the hindbrain?

midbrain, also called mesencephalon, region of the developing vertebrate brain that is composed of the tectum and tegmentum. It is located within the brainstem and between the two other developmental regions of the brain, the forebrain and the hindbrain; compared with those regions, the midbrain is relatively small.

What is the tegmentum rostral to?

The ventral tegmental nucleus, identified as a prominent structure in the pontine tegmentum immediately rostral to the genu of the facial nerve, contained predominantly large neurons and displayed intensive acetylcholinesterase reactivity and substance P-like immunoreactivity.

What is cerebellum in psychology?

The cerebellum (which is Latin for “little brain”) is a major structure of the hindbrain that is located near the brainstem. This part of the brain is responsible for coordinating voluntary movements. It is also responsible for a number of functions including motor skills such as balance, coordination, and posture.

Is the tectum anterior or posterior?

The small portion of the midbrain dorsal (=posterior) to the cerebral aqueduct is the tectum or roof plate. It bears the superior and inferior colliculi (which are concerned with visual and auditory reflexes respectively). The remainder of the midbrain is made up of the cerebral peduncles.
