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:

1. Axon is the long fiber for nerve impulses.
2. Nerve is a bundle of axons.
3. Synapse connects adjacent neurons.
4. Neurotransmitter is the chemical at synapse gap.
5. Reflex is a rapid automatic response.
6. Myelin sheath speeds nerve impulses.
7. Axon terminal is at axon end for neurotransmitters.
8. Nerve impulse is the high - speed signal.
9. Dendrite conducts impulses to cell.
10. Sense receptor receives stimuli.
11. Response is muscle/gland reaction.
12. Cell body has the nucleus.
