The pia mater is the only meninges to continue into a brain sulcus after the brain surface.
What are meninges?
The skull and spinal cord are encased in three tiers of membranes called meninges. These are:
- The pia mater is the fragile inner layer.
- The arachnoid, a fluid-filled web-like structure that forms the brain's intermediate layer, is what gives the brain its cushioning effect.
- The dura mater is the name of the hard outer layer.
The term for the three gaps between the meninges-
- The gaps between the layers of the meninges are known as meningeal spaces.
- Epidural, subdural, and subarachnoid are the three clinically important meningeal compartments.
The function of meninges:
- It acts as a shock absorber, the CNS (central nervous system) will shield our brain from trauma harm, such as a knock to the head.
- They secure our central nervous system and prevent our brain from shifting inside our skull.
Therefore the correct solution is an option (A),i.e., pia mater.
The complete question is:
The only one of the meninges that follows the brain surface into a cerebral sulcus is the
a. pia mater.
b. alma mater.
c. dura mater.
d. arachnoid mater.

Answer:
Seven days after a spring tide, the sun and moon are at right angles to each other. This produces moderate tides known as neap tides, meaning that high tides are a little lower and low tides are a little higher than average. Neap tides occur during the first and third quarter moon, when the moon appears "half full.
Answer:
C
Explanation:
RNA is found mostly in the nucleus but can also be found in the cytoplasm, but it is not limited to it.
Answer:
axon terminals of sensory neurons
axon terminals of motor neurons
Explanation:
Relay neuron are found in the brain and spinal cord between the motor terminals or response and sensory neurons. Sensory neuron transmit signal to the relay neurons connect sensory neuron to motor neuron. The motor neuron then send electrical impulses to the effector which produces a response.
