What is the fourth chamber?

2 fourth chamber is one of the four cavities that form the chamber system; Other cavities are the third chamber and the right and left side chamber. The fourth chamber is full of cerebrospinal fluid and is located between the brain aqueduct and the other brain.

In terms of structure, the fourth chamber has a diamond -shaped structure with upper and lower. Cerebellum forms the upper part of the chamber, commonly referred to as the "roof". Rhomboid Fossa forms the bottom of the chamber, which is referred to as the "floor", and the brain stops form sides or "walls". When cerebrospinal fluid enters the fourth chamber of the cerebral aqueduct, it can leave the subarachnoid space.

The floor of the chamber has numerous properties can help distinguish it. These include OBEX, Colliculus face and Sulcus limited. OBEX is a back part of the fourth chamber and acts as an invisible marker that helps to divide the level and medulla brain. The Oblicary nerve is a colliculus face and Sulcus Limitens is a "border line" that divides alar and basal plates.

The main function of the fourth chamber is to ensure brain suspension by containing cerebrospinal fluid. Other features include creating a central spinal cord channel and brain protection from any trauma that could experience. These are very important functions and trauma on the fourth chamber can be very dangerous.

The development of the chamber together with other chambers of the ventricular system occurs in the central channel of the nerve tube. The third and fourth chambers are created when the central channel expands. This occurs during the first trimester of pregnancy. The fourth chamber is specially formed by a part of the rhombic phalone tube, also called Hindbrain.

There are several diseases that can affect the fourth chamber and the entire ventricular system of the brain. Diseases such as hydrocephalus occur when CSF production is greater than usual. Hydrocephalus may also occur when blocking in brain aqueduct even when normalí csf production. This area of ​​the brain is also a common place for various tumors and cysts in adults.
