Question

The meninges, along with the cerebrospinal fluid (CSF) that circulates in between each meningeal layer, function by: Select one: a. delivering oxygen directly to the CNS. b. regenerating brain cells after they have been damaged. c. acting as a shock absorber for the brain and spinal cord. d. producing leukocytes that protect the brain from infection.

Answer 1

C. ACTING AS A SHOCK ABSORBER FOR THE BRAIN AND SPINAL CORD

Step-by-step explanation:

Meninges are tissues that provide protection, support and also serve metabolic roles for the nervous system. The cerebrospinal fluid is the fluid of the central nervous system and serves as protection, gives buoyancy to the brain, assists in excretion of waste products of metabolism from the brain.

These meninges are of three membranes; the dura mater which is the outer membrane; the pia mater which is rich in blood vessels and the arachnoid mater which keeps the brain in the cerebrospinal fluid. The meninges, along with the cerbrospinal fluid serves to cushion the brain and spinal cord preventing shocks. The pia mater layer of the meninges provides for the delivering of oxygen directly into the CNS and protects the brain from infections through the action of the leucocytes in the blood.
