The meninges are membranes that serve to:

protect the nervous system

bathe the brain in cerebral spinal fluid

carry nutrients to the brain

clear waste products from the brain

a and b would be correct then, after a few google searches!

is the answer a and b?

protect the nervous system

bathe the brain in cerebral spinal fluid

the meninges are used to protect the areas they surround, what can you derive from that?

is it allowing you to click both answers? if not, it's a! hope you get a good grade!

yes, we can click on multiple answers. I am confused as to whether it is just a or a and b.

Thanks a lot :)

The meninges consists of three layers, dura mata, arachnoid mater and pia mater (innermost).

Together, the layers fulfull all four functions of protecting the nervous system from traumas by filling the space with cerebrospinal fluids. Blood vessels and capillaries help to provide nutrients to feed the brain, and to remove wastes.
In short, all four items together form the functions of the meninges.

To find the answer to this question, we can refer to a reliable source such as a medical textbook or scientific publication.

The meninges are a set of three layers of membranes that surround and protect the brain and spinal cord. Their primary function is to provide physical support and protection to the central nervous system.

Here's how each function you mentioned applies to the meninges:

1. Protect the nervous system: The meninges act as a barrier between the brain, spinal cord, and the surrounding structures, shielding them from physical impact, pathogens, and other potential sources of damage.

2. Bathe the brain in cerebrospinal fluid: The meninges are in direct contact with cerebrospinal fluid (CSF), a clear fluid that circulates around the brain and spinal cord. The middle layer of the meninges, called the arachnoid mater, helps enclose and contain the CSF, allowing it to bathe and cushion the brain.

3. Carry nutrients to the brain: While the meninges themselves do not directly carry nutrients, the outermost layer, known as the dura mater, contains blood vessels that supply oxygen and nutrients to the underlying brain tissue. This ensures that the brain receives the necessary nourishment for its optimal functioning.

4. Clear waste products from the brain: The meninges also play a role in clearing waste products from the brain. They help regulate the circulation and filtration of CSF, which aids in the removal of metabolic byproducts and waste materials from brain cells.

Overall, the meninges serve as a protective and supportive barrier for the central nervous system while facilitating the circulation of cerebrospinal fluid, supplying nutrients, and assisting in waste clearance.
