What is the cavity within the brain?
Cranial cavity
Cranial cavity–the space occupied by the brain, enclosed by the skull bones.
What are the four ventricles?
Anatomical terms of neuroanatomy The fourth ventricle is one of the four connected fluid-filled cavities within the human brain. These cavities, known collectively as the ventricular system, consist of the left and right lateral ventricles, the third ventricle, and the fourth ventricle.
What is the function of the 4th 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.
How many foramen of Monro are there?
Interventricular foramina (neuroanatomy)

How many types of cavities are there?
Cavities are decayed areas of your teeth that develop into tiny openings or holes. The three types of cavities are shown here. Smooth surface cavities occur on the smooth sides of your teeth, while root cavities develop on the surface over the roots. Pit and fissure cavities occur on the chewing surface of your teeth.
Where does the 4th ventricle drain?
spinal cord
The fourth ventricle is the most inferiorly located ventricle, draining directly into the central canal of the spinal cord. Superiorly, it connects to the third ventricle through a thin canal called the cerebral aqueduct of Sylvius.
Where does 4th ventricle drain?
What are the cavities of the ventricular system that lie within the brainstem?
The ventricular system accounts for the production and circulation of cerebrospinal fluid. The ventricular system is a set of four interconnected cavities known as cerebral ventricles in the brain. Within each ventricle is a region of choroid plexus which produces the circulating cerebrospinal fluid (CSF).
Where is the 4th ventricle in the brain?
medulla oblongata
The fourth ventricle is a diamond-shaped cavity located posterior to the pons and upper medulla oblongata and anterior-inferior to the cerebellum. The superior cerebellar peduncles and the anterior and posterior medullary vela form the roof of the fourth ventricle.
What is foreman of Monroe?
The interventricular foramen, also known as foramen of Monro, is part of the ventricular system and the connection between the third ventricle and the lateral ventricle.
Where are the four ventricles located in the brain?
There are four of these cavities in the brain, three of which are located within the cerebrum ( lateral ventricles and the third ventricle ). These cavities and their content constitute the ventricular system of the brain.
What are the names of the grooves in the cerebral cortex?
The cerebral cortex has sulci (small grooves), fissures (larger grooves) and bulges between the grooves called gyri. Scientists have specific names for the bulges and grooves on the surface of the brain. Decades of scientific research have revealed the specific functions of the various regions of the brain.
What kind of fluid does the human brain contain?
Human brain contains four fluid-filled cavities, which are known as ventricles. These ventricles are concerned with the production and circulation of cerebrospinal fluid. Ventricles are hollow cavities of the brain, that contain the cerebrospinal fluid (CSF), which circulates within the brain and spinal cord.
Where does the fourth ventricle of the brain receive CSF?
The fourth ventricle is the last in the system – it receives CSF from the third ventricle via the cerebral aqueduct. It lies within the brainstem, at the junction between the pons and medulla oblongata. Subarachnoid cisterns – bathes the brain, between arachnoid mater and pia mater. Here the CSF is reabsorbed back into the circulation.
