Question

the space between two neurons or between a neuron and a receptor organ is known as a

plexus
dendrite
ganglion
synapse

question 5
1 pts

the white protective covering over some parts of the spinal cord and the axon of most peripheral nerves is the ______.

neuroglia
neurotransmitter
myelin sheath
pia mater

Explanation:

Analyze the first question

Using the Nervous System Terminology knowledge point, we identify the anatomical space described. The prompt asks for the space between two neurons or between a neuron and a receptor organ.

• A plexus is a network of nerves.
• A dendrite is a receiving branch of a neuron.
• A ganglion is a cluster of nerve cell bodies.
• A synapse is the specialized junction or gap where signals are transmitted.

Analyze the second question

The second question asks for the white protective covering over parts of the spinal cord and peripheral nerve axons.

• Neuroglia are supporting cells, not a specific sheath.
• Neurotransmitters are chemical messengers.
• The myelin sheath is a lipid-rich, white protective wrapping that insulates axons.
• The pia mater is the delicate innermost membrane enveloping the brain and spinal cord.

Answer:

Question 1

• plexus
• dendrite
• ganglion
• synapse (Correct answer)

Question 2

• neuroglia
• neurotransmitter
• myelin sheath (Correct answer)
• pia mater
