Question

Name the fluid present in the cavities of the brain and spinal cord.

Answer 1

Hint: The brain and spinal cord filled space with the cerebrospinal fluid that was found in the space and cavity in the empty space of the both. The secretion of the fluid there are cells in the choroid plexus. The fluid is cerebrospinal fluid that is present in the ventricles cavities of the brain that are interconnected within the brain.

Complete answer:
CSF is the transparent and colorless fluid that circulates the cavity through the central canal of spinal cord, subarachnoid space and brain. The part of the extracellular fluid is approximately 150 ml volumes and 0.3 ml/ min rate of formation, 1.005 specific gravity and it’s a kind of alkaline reaction. More amount of potassium and sodium contained in the ECF and CSF part in some lymphocytes. The ventricles do not contain any cells after the secretion from the CSF. In the spinal cord the flow of the lymphocytes occurred. Within the ventricles the formation of the choroid plexus in the capillaries that is covered by the internal ventricle of the ependymal covering and pia mater. The secretion is the formation of the CSF and not involved in the dialysis and ultrafiltration in the body. The secretion of the CSF by stimulating the choroid plexus in the extraction of the pituitary gland in the pilocarpine that also affects the formation of the CSF. Injection of hypotonic saline and hypertonic saline also affect the formation of the CSF.

Note: In the spinal veins and Dural sinuses the absorption of the arachnoid villi occurred and in the perivascular space the per neural space into the cervical lymphatics are absorbed the small amount of 500 ml of the SCF. Acts as a buffer, protect the brain from shock, and countercoup injury and help to receive the brain's severe blow or maintain the regulation of the cranial content volume of the body.
