- The lateral ventricles are part of the ventricular system of the brain. Both cerebral hemispheres contain a lateral ventricle. The lateral ventricles are the largest of the ventricles.he trigone of the lateral ventricle is a triangular area defined by the temporal horn inferiorly, the occipital horn posteriorly, and the body of the lateral ventricle anteriorly. The cella media is the central part of the lateral ventricle. Ependyma cover the inside of the lateral ventricles and are epithelial cells.

Nervous System Part 2 There are cavities in your brain called ventricles. The structure located in the ventricles that produces cerebrospinal fluid is called the choroid plexus. The cerebrospinal fluid is a clear, protective fluid made by the cells of the choroid plexus, and it is commonly abbreviated CSF.

Ventricles of the Brain Overview. 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 following images).he largest cavities of the ventricular system are the lateral ventricles. Each lateral ventricle is divided into a central portion, formed by the body and atrium (or trigone), and 3 lateral extensions or horns of the ventricles. The central portion or the body of the ventricle is located within the parietal lobe.

Medulla Between the posterior median and posterior lateral sulcus are the tubercles of the nuclei gracilis (medially) and cuneatus (laterally). Just above the tubercles, the posterior aspect of the medulla is occupied by a triangular fossa, which forms the lower part of the floor of the fourth ventricle. The fossa is bounded on either side by the inferior cerebellar peduncle, which connects the medulla to the cerebellum.

Ventricles of the Brain Cerebrospinal fluid. CSF is a clear, watery fluid that fills the ventricles of the brain and the subarachnoid space around the brain and spinal cord. CSF is produced primarily by the choroid plexus of the ventricles (up to 70% of the volume), most of it being formed by the choroid plexus of the lateral ventricles.

Forebrain Hypothalamus, region of the brain lying below the thalamus and making up the floor of the third cerebral ventricle. The hypothalamus is an integral part of the brain. It is a small cone-shaped structure that projects downward from the brain, ending in the pituitary (infundibular) stalk, a tubular connection to the pituitary gland.

Fourth ventricle Inside the brain, there are four cavities, called ventricles. The right and left lateral ventricles and the third and fourth ventricles compose the ventricular system.The fourth ventricle contains cerebrospinal fluid. It has a diamond shape and is located in the upper portion of the medulla.uch like other portions of the ventricular system inside the brain, the fourth ventricle develops from the area inside the neural tube (the structure in an embryo that becomes the brain and spinal cord) called the central canal. During gestation, the ventricles form during the first three months of pregnancy.

Ventricles of the Brain The fluid (cerebrospinal fluid) is produced in the ventricular system of the brain. There are four such hollow spaces in the brain that house cerebrospinal fluid (CSF): two lateral ventricles, a third ventricle and a fourth ventricle. This article will look at the structure of this system and how it helps the brain.

- The third ventricle is surrounded by the structures of the diencephalon of the brain. The diencephalon is part of the central processing unit or motherboard of the brain. It connects and coordinates the lobes of the brain on its rostral (top) end, to the brainstem, cerebellum and spinal cord on its caudal (lower) end.he posterior perforated substance is the area of the floor of the third ventricle that is penetrated by many blood vessels. The subthalamus portion of the floor of the third ventricle is located beneath the thalamus toward the rear and flanks of the hypothalamus.

Fourth ventricle This ventricle has a roof and a floor. The roof is composed of the cerebellum, located at the back of the brain, and the floor is formed by the rhomboid fossa, a depression in the brainstem. Within the floor is the facial colliculus, sulcus limitans, and the obex. Much like other portions of the ventricular system inside the brain, the fourth ventricle develops from the area inside the neural tube (the structure in an embryo that becomes the brain and spinal cord) called the central canal.

- The third and fourth ventricles are located in the center of the brain. The lateral ventricles communicate with the third ventricle through an opening called the interventricular foramen. Both lateral ventricles are filled with cerebrospinal fluid.
