What is a lateral vent?
Lateral ventricles are two c-shaped cavities one on each side of cerebral hemisphere. It consists of a central part called body and three extensions: anterior (frontal horn), posterior (occipital horn), and inferior (temporal horn).
What is the function of the lateral ventricles in the brain?
The lateral ventricles, like the rest of the brain’s ventricles, help provide a fluid-filled compartment for the brain and immerse it for safety, as well as produce and circulate cerebrospinal fluid.
What do frontal horns do?
The frontal horn (Fig 1) extends anteriorly from the foramina of Monro and communicates with the body of the lateral ventricles posteriorly. The anterior wall and roof are formed by the genu of the corpus callosum, and the floor is formed by the rostrum. The head of the caudate nucleus forms the lateral wall.
What are the lateral ventricles in the brain?
The lateral ventricles are the two largest ventricles of the brain and contain cerebrospinal fluid (CSF). Each cerebral hemisphere contains a lateral ventricle, known as the left or right ventricle, respectively.
Do the lateral ventricles communicate?
The lateral ventricles communicate with the third ventricle through interventricular foramens, and the third ventricle communicates with the fourth ventricle through the cerebral aqueduct (see the image below).
What does enlarged lateral ventricles mean?
Mild enlargement of the lateral ventricles is a structural brain abnormality observed in neuropsychiatric disorders that are thought to be the result of abnormal prenatal brain development, including schizophrenia (1, 2), autism (3), and attention-deficit/hyperactivity disorder(4, 5).
Do lateral ventricles communicate?
What does the lateral sulcus do?
The lateral sulcus (Sylvian fissure) is a very deep fold seen on the lateral surface of the hemisphere running in an anterior to posterior direction and serves to separate the temporal lobe from the frontal and parietal lobes.
What does it mean to have enlarged ventricles in brain?
Hydrocephalus is the abnormal enlargement of the brain cavities (ventricles) caused by a build-up of cerebrospinal fluid (CSF). Usually, the body maintains a constant circulation and absorption of CSF. Untreated, hydrocephalus can result in brain damage or death.
What do ventricles do in the heart?
The right ventricle pumps the oxygen-poor blood to the lungs through the pulmonary valve. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle through the mitral valve. The left ventricle pumps the oxygen-rich blood through the aortic valve out to the rest of the body.
What does the lateral ventricles do?
Lateral ventricles. The ventricular system acts as a continuation of the central canal of the spinal cord, a similar structure that contains cerebrospinal fluid and runs the length of the neck and trunk. The separate sections of the ventricular system are connected through small holes known as foramina.
What is the purpose of venting in plumbing?
The plumbing vent, also known as a vent stack, helps regulate the air pressure in your plumbing system. Just as drain pipes remove water and waste from your home, the plumbing vent pipe – also known as a plumbing air vent – removes gas and odors.
What are the parts of the posterior horn of the lateral ventricle?
The posterior horn of the lateral ventricle extends posteromedially into the occipital lobe, and like other parts of the lateral ventricle it has a roof, lateral wall and a medial wall. The roof and lateral wall are formed by the tapetum, while the medial wall shows two elevations,…
What is the difference between lateral and medial roof?
The lateral part of the roof (lateral wall) is formed by fibres of the tapetum, while the medial part of the roof is formed by the tail of the caudate nucleus and the stria terminalis. These structures are continuous into the roof of the inferior horn from the floor of the central part.
