Question

1. relative to neuron anatomy, match the anatomical terms given in column b with the appropriate descriptions of functions provided in column a. place the correct term or letter response in the answer blanks.

column a

1. releases neurotransmitters
2. conducts local electrical currents toward the cell body
3. increases the speed of impulse transmission
4. location of the nucleus
5. generally conducts impulses away from the cell body
6. clustered ribosomes and rough er (endoplasmic reticulum)

column b
a. axon
b. axon terminal
c. dendrite
d. myelin sheath
e. neuron cell body
f. nissl bodies

Explanation:

1. Axon terminals (B) are responsible for releasing neurotransmitters to communicate with other neurons.
2. Dendrites (C) receive signals and conduct local electrical currents toward the cell body.
3. The myelin sheath (D) insulates axons and increases the speed of impulse transmission.
4. The neuron cell body (E) contains the nucleus.
5. Axons (A) typically conduct impulses away from the cell body.
6. Nissl bodies (F) are clusters of ribosomes and rough endoplasmic reticulum in the neuron cell body.

Answer:

1. B. Axon terminal
2. C. Dendrite
3. D. Myelin sheath
4. E. Neuron cell body
5. A. Axon
6. F. Nissl bodies
