What is the third chamber?
The third chamber is one of the four cavities filled with fluid in the ventricular system in the human brain. It extends from the central canal of the spinal cord and is filled with cerebrospinal fluid (CSF). The other four chambers consist of two side chambers and the fourth chamber. Together they provide brain protection and stability. As a result, the ventricular system is necessary for proper neural development and growth in humans. More precisely, the third chamber comes from a part of the nerve tube, which is present in the anterior brain. This is also known as Prosencephalon.
The third chamber is a narrow cavity between two side chambers in the chamber system. The third chamber is essentially a cavity of the middle line in the brain, which lies on top of optical chiasm, tuber cinereum, mamilary body, infundibulum, rear perforated substance and the highest part of the mesencephalic tegment. It is also bound by thalam and hypothalamus on both sides. The roof of the third chamber consists of an ependy layer, which is a thin lining of the epithelial membrane.
The third chamber also has several small hollow areas or indentations called niches. Preoptic niches are on the back of the optical chiasm, where optical nerves pass into the brain. Furthermore, the infection is an infundibular niche in the form of funnels extending to the infundibul. Mamilary of the body that holds into the cavity causes the third niche to be named Mamilary. Finally, the pineal -cod is in the back of the third chamber and extends to the pineal gland.
Connection between four chambers allows the CSF flow between the third chamber and others. The third chamber mainly communicates with the side chambers of the front through interventricular foramen. It also communicates with the fourth chamber of the rear through the brain aqueduct, which is also known as the aqueduct Sylvius.
The main purpose of the ventricular system is to produce and circulate CSF around the brain. This polish the brain and spinal cord before damage in the skull. The concussion or bruises on the brain showfrom contact with the skull during a harsh impact. CSF also provides buoyancy to support brain against gravity and floating brain.
