Where is the ventral surface located?

The terms dorsal and ventral are also often used to describe the relative location of a body part. For example, the stomach is ventral to the spinal cord, which means that the stomach is located in front of the spinal cord.

What is the ventral surface of the midbrain?

The ventral region of each crus is called the crus cerebri, and contains the white matter from the cortex. The dorsal regions of the crura are continuous with each other and together are called the tegmentum of the midbrain. The tegmentum contains certain neural pathways, reticular formation, and cranial nerve nuclei.

Where is the midbrain located in the brain?

Located towards the base of your brain is a small but important region called the midbrain (derived from the developmental mesencephalon), which serves as a vital connection point between the other major regions of the brain – the forebrain and the hindbrain.

What is the location and function of the midbrain?

Midbrain, also called mesencephalon, region of the developing vertebrate brain that is composed of the tectum and tegmentum. The midbrain serves important functions in motor movement, particularly movements of the eye, and in auditory and visual processing.

The midbrain is located between the diencephalon and the hind brain, or brain stem. More specifically, it can be found ventral to the cerebral cortex and between the cerebral pedicles of the diencephalon and the pons.

Where is the ventral tegmental area in the brain?

The ventral tegmental area, or VTA, is in the midbrain, situated adjacent to the substantia nigra.

Where are the pons, medulla and midbrain located?

The midbrain connects the pons and cerebellum with the forebrain and can be divided into a ventral part, the tegmentum, and a dorsal part, the tectal or quadrigeminal plate ( Figs 2, 3 ). The cerebral aqueduct of Sylvius is located in the midbrain and joins the third and fourth ventricles, surrounded by periaqueductal gray matter ( 3 ).

Where does venous drainage of the midbrain take place?

Venous drainage of the midbrain and pons is achieved by both the vertebrobasilar veins and the venous sinus systems. Lateral and posterior mesencephalic veins drain the upper pons and the midbrain to the great cerebral vein of Galen, which drains to the confluence of sinuses by way of the straight sinus.
