What is the 4th ventricle of the brain?
The fourth ventricle is the most inferiorly located ventricle, draining directly into the central canal of the spinal cord. The lateral walls of the fourth ventricle are formed by the cerebellar peduncles. The superior part of these walls is formed by the superior cerebellar peduncle.
How many temporal lobes are in the brain?
There are two temporal lobes located on both sides of the brain that are in close proximity to the ears. The primary function of the temporal lobes is to processing auditory sounds. Other functions of the temporal lobe include:
What do the ventricles do in the brain?
Ultimately, the overarching function of ventricles is to circulate said fluid throughout the organ or body. In the case of the brain ventricular system, the fluid is CSF and the circulation occurs throughout the central nervous system, primarily the brain and spinal cord.
What is the meaning of "ventricles of the brain"?
The brain ventricles are four cavities located within the brain that contain cerebral spinal fluid (CSF) . There are two lateral ventricles- one on each side of the cerebral cortex. The lateral ventricles are continuous with the third ventricle, which is lower in the brain.
How many ventricles are in the brain?
The ventricular system is composed of 2 lateral ventricles, the third ventricle, the cerebral aqueduct, and the fourth ventricle (see the images below).
How many ventricles are in the brain and what is their function?
The ventricles (in purple). The ventricles are four interconnected cavities distributed throughout the brain that produce and contain cerebrospinal fluid (CSF).
Does the brain have ventricles?
Your brain floats in a bath of cerebrospinal fluid. This fluid also fills large open structures, called ventricles, which lie deep inside your brain. The fluid-filled ventricles help keep the brain buoyant and cushioned.
What part of brain has no ventricles?
Hence, the correct answer is 'Cerebellum'
What are the 4 ventricles of brain?
There are four ventricles of the brain: the 2 lateral ventricles, third ventricle, and fourth ventricle. The ventricles are lined with a specialised membrane called the choroid plexus, which is made up of ependymal cells.
What is the purpose of the 4 ventricles in the brain?
Brain ventricles are cavities within the brain that produce and store cerebrospinal fluid (CSF). This liquid surrounds your brain and spinal cord, cushioning them and protecting them from trauma. It is also responsible for removing waste and delivering nutrients to your brain.
What is the 3rd ventricle of the brain?
The third ventricle is a narrow funnel-shaped cavity of the brain that is located in the midline between the two hemispheres of the diencephalon of the forebrain. The third ventricle makes up the central part of the brain and facilitates communication between other ventricles.
How do you find the ventricles of the brain?

The lateralMoreThere are 2 C shaped lateral ventricles one in each of the cerebral hemispheres. The lateral ventricles are connected to a third ventricle by an opening called the interventricular.
What animal has a heart but no brain?
JellyfishThey have a mesh of nerve cells all over the body. Hence they are sensitive to touch. The respiration in such animals is carried through their skin and takes oxygen inside. Jellyfish have no brain and heart.
Do brain ventricles grow?
There are spaces within the brain (ventricles) that are also filled with CSF. Ventriculomegaly is a condition in which the ventricles appear larger than normal on a prenatal ultrasound. This can occur when CSF becomes trapped in the spaces, causing them to grow larger.
What is no brain called?
Anencephaly (pronounced an-en-sef-uh-lee) is a serious birth defect in which a baby is born without parts of the brain and skull.
What is the function of the 3rd ventricle?
The third ventricle sends messages to and receives messages from the lateral ventricles, which are located in front of the third ventricle, and the aqueduct of the midbrain, which is located directly behind the third ventricle. The hypothalamus and thalamus are located on the sides of the third ventricle.
