Question

1. match the descriptions in the table below with the terms in the list.

a. synapse b. axon c. myelin sheath d. nerve impulse e. sense receptor f. response,
g. reflex h. cell body i. dendrite j. nerve k. neurotransmitter l. axon terminal
term
description

1. the long fiber that carries the nerve impulses
2. a bundle of axons.
3. the connection between adjacent neurons.
4. the chemical secreted into the gap between neurons at a synapse.
5. a rapid automatic response to a stimulus.
6. the covering of fatty material that speeds up the passage of nerve impulses.
7. the structure at the end of an axon that produces neurotransmitters to transmit the nerve impulse across the synapse.
8. the high speed signals that pass along the axons of nerve cells.
9. the branching filaments that conduct nerve impulses towards the cell.
10. the sense organ or cells that receive stimuli from within and outside the body.
11. the reaction to a stimulus by a muscle or gland.
12. the part of the nerve cell containing the nucleus.

Explanation:

To solve this matching problem, we analyze each description and match it with the correct term based on the definitions of nervous system components:

1. The long fiber carrying nerve impulses is the axon (B).
2. A bundle of axons is a nerve (J).
3. The connection between adjacent neurons is a synapse (A).
4. The chemical at synapses is a neurotransmitter (K).
5. A rapid automatic response is a reflex (G).
6. The fatty covering speeding impulses is myelin sheath (C).
7. The end of an axon producing neurotransmitters is axon terminal (L).
8. High - speed signals in axons are nerve impulses (D).
9. Branching filaments conducting toward the cell are dendrites (I).
10. Sense organs/cells receiving stimuli are sense receptors (E).
11. Muscle/gland reaction to stimulus is response (F).
12. The nerve cell part with the nucleus is cell body (H).

Answer:

1. B. Axon
2. J. Nerve
3. A. Synapse
4. K. Neurotransmitter
5. G. Reflex
6. C. Myelin sheath
7. L. Axon terminal
8. D. Nerve impulse
9. I. Dendrites
10. E. Sense receptor
11. F. Response
12. H. Cell body
