Question

question 7
1 pts
some parasympathetic postganglionic neurons have their cell bodies in nuclei in the brainstem.
true
false
question 8
1 pts
the layer of the meninges that serves as the inner periosteum of the cranial bone is the:
pia mater.
arachnoid membrane.
dura mater.
none of the above is correct.
question 9
1 pts
the brainstem does not include the:
pons.
medulla.
midbrain.
cerebellum.

Explanation:

• Question 7: Parasympathetic pre - ganglionic neurons have their cell bodies in nuclei in the brainstem (e.g., oculomotor nucleus, superior and inferior salivatory nuclei, dorsal motor nucleus of the vagus). Post - ganglionic neurons have their cell bodies in ganglia close to or within the target organ, not in the brainstem nuclei.
• Question 8: The dura mater has two layers. The periosteal layer (outer layer) serves as the inner periosteum of the cranial bone. The pia mater is the innermost layer closely covering the brain, and the arachnoid membrane is in between the dura and pia.
• Question 9: The brainstem consists of the midbrain, pons, and medulla. The cerebellum is a separate structure attached to the brainstem but is not part of the brainstem itself.

Answer:

• Question 7: B. False
• Question 8: C. dura mater
• Question 9: D. cerebellum
