Question

question 1
1 pts
impulse conduction is fastest in neurons that are:
motor
myelinated
unmyelinated
sensory
cerebral
question 2
1 pts
which is not part of the central nervous system?
brain
thalamus
medulla
spinal cord
autonomic nervous system

Explanation:

• Question 1: Myelinated neurons have a myelin sheath that enables saltatory conduction, which is faster than continuous conduction in unmyelinated neurons. Motor, sensory, and cerebral neurons can be myelinated or unmyelinated, but the key factor for fast impulse conduction is myelination.
• Question 2: The central nervous system (CNS) consists of the brain and spinal cord. The thalamus is part of the brain, and the medulla is part of the brainstem (which is part of the brain). The autonomic nervous system is part of the peripheral nervous system (PNS), not the CNS.

Answer:

• Question 1: myelinated
• Question 2: Autonomic nervous system
