cerebral aqueduct

It forms the floor of the midbrain that surrounds the cerebral aqueduct.

The second part is the tegmentum and is ventral to the cerebral aqueduct.

It is located in the posterior part of the third ventricle, overlying the cerebral aqueduct.

Partial or total obstruction of the cerebral aqueduct during development can lead to congenital hydrocephalus.

This symptom however occurs secondary to hydrocephalus, which is a result from compression of the cerebral aqueduct.

Additionally, there are two protrusions on the posterior aspect, above the cerebral aqueduct:

The cerebral aqueduct is a narrow channel in the midbrain, which connects the third and fourth ventricles.

It extends from cerebral aqueduct of the midbrain to central canal of the spinal cord.

It communicates with the fourth ventricle posteriorly by the cerebral aqueduct (of Sylvius).

Also noticed were Hemorrhages in the gray matter around the third and fourth ventricles and the cerebral aqueduct.

Pineal tumors also can cause compression of the cerebral aqueduct, resulting in a noncommunicating hydrocephalus.

Both sections will show the cerebral aqueduct, which connects the third and fourth ventricle and the periaqueductal gray.

Periaqueductal gray: The area around the cerebral aqueduct, which contains various neurons involved in the pain desensitization pathway.

The nucleus of the trochlear nerve is located in the caudal mesencephalon beneath the cerebral aqueduct.

The tectum includes the superior and inferior colliculi and is the dorsal covering of the cerebral aqueduct.

The cerebral aqueduct runs through the midbrain, and is the communication between the third ventricle and fourth ventricle.

If narrowing of the cerebral aqueduct occurs, many neurological symptoms may exist, including headaches, vertigo, nausea, eye sensitivity, and ataxia.

The cerebral aqueduct, similarly to other parts of the ventricular system of the brain, develops from the central canal of the neural tube.

The cerebral aqueduct may be blocked at the time of birth or may become blocked later in life because of a tumor growing in the brainstem.

Throughout embryonic development, the cells within the midbrain continually multiply and compress the still-forming Aqueduct of Sylvius or cerebral aqueduct.

If the foramina of the fourth ventricle or the cerebral aqueduct are blocked, cereobrospinal fluid (CSF) can accumulate within the ventricles.

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.

The tectum, pretectum, cerebral peduncle and other structures develop out of the mesencephalon, and its cavity grows into the mesencephalic duct (cerebral aqueduct).

Periaqueductal gray (PAG; also called the "central gray") is the gray matter located around the cerebral aqueduct within the tegmentum of the midbrain.

The fluid-filled cerebral ventricles (lateral ventricles, third ventricle, cerebral aqueduct, fourth ventricle) are also located deep within the cerebral white matter.
