The midbrain tegmentum is the part of the midbrain extending from the substantia nigra to the cerebral aqueduct in a horizontal section of the midbrain. 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 pontine tegmentum, or dorsal pons, is the dorsal part of the pons located within the brainstem. The ventral part or ventral pons is known as the basilar part of the pons. The pontine tegmentum is all the material dorsal from the basilar pons to the fourth ventricle. Along with the dorsal surface of the medulla oblongata, it forms part of ...
The midbrain tegmentum is also an important part of the dopaminergic system which is essential for feelings of reward and pleasure. Two regions in the midbrain tegmentum are of particular interest. The first one is the substantia nigra which is an important part of the nigrostriatal pathway. This pathway serves to coordinate motor movements and ...
The brainstem (or brain stem) is the posterior stalk-like part of the brain that connects the cerebrum with the spinal cord. [1] In the human brain the brainstem is composed of the midbrain, the pons, and the medulla oblongata. [1] The midbrain is continuous with the thalamus of the diencephalon through the tentorial notch, and sometimes the ...
61993. Anatomical terms of neuroanatomy. [edit on Wikidata] The midbrain or mesencephalon is the rostral -most portion of the brainstem [2] connecting the diencephalon and cerebrum with the pons. [3] It consists of the cerebral peduncles, tegmentum, and tectum. It is functionally associated with vision, hearing, motor control, sleep and ...
The ventral tegmental area (VTA) (tegmentum is Latin for covering), also known as the ventral tegmental area of Tsai, [1] or simply ventral tegmentum, is a group of neurons located close to the midline on the floor of the midbrain. The VTA is the origin of the dopaminergic cell bodies of the mesocorticolimbic dopamine system and other dopamine ...
Basilar part of pons. The basilar part of pons, also known as basis pontis, or basilar pons, is the ventral part of the pons (ventral pons) in the brainstem; the dorsal part (dorsal pons) is known as the pontine tegmentum. The basilar part of the pons makes up two thirds of the pons. [1] It has a ridged appearance with a shallow groove at the ...
Anatomical terms of neuroanatomy. [edit on Wikidata] The central tegmental tract[1] is a structure in the midbrain and pons. It contains: ascending second-order axons projecting from the gustatory nucleus [citation needed] of nucleus solitarius [2]: 112 to the ventral posteromedial nucleus [2]: 473 of thalamus [2]: 112 (third-order neurons in ...
