What is the third ventricle of the brain responsible for?
The third ventricle can be described as a cuboid structure that has a roof, floor and four walls (anterior, posterior, and two lateral). Similar to the other brain ventricles, the main function of the third ventricle is to produce, secrete and convey cerebrospinal fluid.
What is the function of lateral ventricle?
The right and left lateral ventricles are structures within the brain that contain cerebrospinal fluid, a clear, watery fluid that provides cushioning for the brain while also helping to circulate nutrients and remove waste.
What is the function of fourth ventricle?
The main function of this ventricle is to protect the human brain from trauma (via a cushioning effect) and to help form the central canal, which runs the length of the spinal cord. This ventricle has a roof and a floor.
What happens if ventricles enlarge?
The ventricles enlarge to handle the increased volume of CSF, thus compressing the brain from within and eventually damaging or destroying the brain tissue.
What is ventricular expansion?
Ventricular enlargement is a brain condition that occurs when the lateral ventricles become dilated. The most common definition uses a volume to brain index value derived from MRI and CT reconstruction of the lateral and third ventricles.
What is inferior lateral ventricle?
The inferior (temporal) horn is the largest component of the lateral ventricle. It begins at the posterior end of the central region, and runs anteroinferiorly into the temporal lobe. It has an anterior end that reaches close to the uncus of the cerebrum, a floor, and a roof.
How many ventricles are there in the cerebral hemisphere?
Ventricle, cerebral: One of a system of four communicating cavities within the brain that are continuous with the central canal of the spinal cord. They include two lateral ventricles in the cerebral hemispheres, each consisting of a triangular central body and four horns.
What is the 4th ventricle of the brain?
The fourth ventricle, which is the lowest of the four ventricles of the brain, extends from the aqueduct of the midbrain to the central canal of the upper end of the spinal cord, with which it communicates, through the two foramina of Luschka and the foramen of Magendie. The ventricles are filled with cerebrospinal fluid. Could I have CAD?
What is cerebral ventricular enlargement?
Cerebral ventricular enlargement is a non-specific alteration in gross brain structure, the end result of numerous pathological processes and even more numerous etiologies. It is a biological marker of a past or present brain disorder, usually one involving either degeneration of brain tissue or obstruction to cerebrospinal fluid circulation.
