Explanation:

The meninges are the membranous tissues that cover the spinal cord and the brain, providing support and protection to these organs. They are of three layers.

A) The Dura mater

B) The arachnoid mater

C) The pia mater

The Dura is the outermost meningeal layer and lies directly under the vertebral column bones and skull. The subdural space is the space between the Dura mater and the Arachnoid mater.

The Arachnoid mater lies in the middle of the Dura and Pia mater. Under the Arachnoid layer is the subarachnoid space which contains the cerebrospinal fluid. The cerebrospinal fluid acts as a shock absorber and a cushion to the brain and spinal cord.

The Pia mater lies under the subarachnoid space and directly on the spinal cord and brain and is highly vascularised.

Answer from: ozzy55

The correct answer to the question is option C

Explanation: The dura mater, arachnoid mater and the pia mater are all known as the meninges.

The meninges are membranous covering of the brain and the spinal cord,they support,protect and provide metabolic needed to the central nervous system.

The dura mater is the outermost fibrous covering of the brain and the spinal cord,the middle covering is known as the arachnoid mater and it sits directly beneath the dura mater.

The innermost layer/covering is known as the pia mater,it sits/directly covers the brain and the spinal cord.between the pia mater and the arachnoid mater is a potential space known as the subarachnoid space,it contains interstitial fluid and cerebrospinal fluid which protects the brain,supplies the nervous system tissues with nutrients and helps in the removal of waste products from cerebral metabolism.

The subdural space is the space between the dura mater and the arachnoid mater and it only exist in pathological conditions.

Astudy by solloch and et. al., in 2017, gives the map above which shows the frequency of alleles with a ccr5-delta32 mutations over 87 different countries. this mutation deletes the presence of a co-receptor (ccr5) on the outside of human t-cells (lymphocytes). some viruses, such as the one responsible for the black death and human immunodeficiency virus (hiv), require this receptor for attachment to host cells during the infection process. the black death was an epidemic that passed over northern europe during the 14th century killing nearly 60% of europeans. according to this information, which explanation best explains why northern europeans show a greater immunity for hiv than some other parts of the world?
