Question

Indicate whether the statements are true or false.

1. Sensory fibers conduct impulses toward the CNS.
2. The spinal nerves are part of the central nervous system.
3. The cervical nerves are in the region of the neck.
4. Myelinated neurons make up the gray matter of the CNS.
5. CSF forms in the ventricles of the brain.
6. The fiber that carries impulses toward the neuron cell body is the axon.
7. There are 12 pairs of cranial nerves.
8. The innermost layer of the meninges is the pia mater.
(Enter your responses and submit to compare to the correct answer.)

Answer 1

Sensory fibers transmit impulses to the CNS which is true. Spinal nerves are part of the Peripheral Nervous System, not the CNS. The cervical nerves are indeed located in the neck region.

Step-by-step explanation:

Let's address the statements provided:

1. Sensory fibers conduct impulses toward the CNS (Central Nervous System) - True.
2. The spinal nerves are part of the central nervous system - False, they are part of the Peripheral Nervous System (PNS).
3. The cervical nerves are in the region of the neck - True.
4. Myelinated neurons make up the gray matter of the CNS - False, they make up the white matter.
5. CSF (Cerebrospinal Fluid) forms in the ventricles of the brain - True.
6. The fiber that carries impulses toward the neuron cell body is the axon - False, it is the dendrite.
7. There are 12 pairs of cranial nerves - True.
8. The innermost layer of the meninges is the pia mater - True.
