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 causes small ventricles in the brain?
This finding is presumably due to non-specific and diffuse swelling of brain parenchyma, and is illustrated in cases of trauma, neoplasm, encephalitis, pseudotumor cerebri, metabolic disorder, and probable dilantin effect. It is likely that other causes will be encountered in the future.
Where is CSF made?
choroid plexusCSF is produced mainly by a structure called the choroid plexus in the lateral, third and fourth ventricles. CSF flows from the lateral ventricle to the third ventricle through the interventricular foramen (also called the foramen of Monro).
How are particular ventricles connected to each other?
The lateral ventricle is connected with the third ventricle via the foramen of monro. The third ventricle is connected to the fourth ventricle via the cerebral aqueduct (also called the aqueduct of Sylvius).
What are the 4 ventricles of the brain filled with?
The ventricles of the brain are a communicating network of cavities filled with cerebrospinal fluid (CSF) and located within the brain parenchyma. The ventricular system is composed of 2 lateral ventricles, the third ventricle, the cerebral aqueduct, and the fourth ventricle (see the images below).
What are brain ventricles responsible for?
The ventricular system is a set of communicating cavities within the brain. These structures are responsible for the production, transport and removal of cerebrospinal fluid, which bathes the central nervous system.
What is cerebrospinal fluid made up of?
Abstract. Cerebrospinal fluid (CSF) is a clear, colourless ultrafiltrate of plasma with low protein content and few cells. The CSF is mainly produced by the choroid plexus, but also by the ependymal lining cells of the brain’s ventricular system.
Can enlarged brain ventricles be normal?
The brain may shrink in older patients or those with Alzheimer’s disease, and CSF volume increases to fill the extra space. In these instances, the ventricles are enlarged, but the pressure usually is normal.
Which is the largest part of the brain?
CerebrumCerebrum: is the largest part of the brain and is composed of right and left hemispheres. It performs higher functions like interpreting touch, vision and hearing, as well as speech, reasoning, emotions, learning, and fine control of movement. Cerebellum: is located under the cerebrum.
What is the fourth ventricle?
The fourth ventricle is a cavity of hindbrain connected to the third ventricle by a narrow cerebral aqueduct. The fourth ventricle is a diamond-shaped cavity located dorsal to the pons and upper medulla oblongata and anterior to the cerebellum (Fig. … Inferiorly, it extends into the central canal of medulla.
What material does the lateral ventricle contain?
The lateral ventricles are the two largest ventricles of the brain and contain cerebrospinal fluid (CSF).
What kind of cavity is a ventricle?
The ventricles (in purple). The ventricles are four interconnected cavities distributed throughout the brain that produce and contain cerebrospinal fluid (CSF). The two lateral ventricles are C-shaped chambers found in the cerebral hemispheres (one in each hemisphere).
