AP Psych Unit #1A: Biological Bases of Behavior

The long fiber that carries the nerve impulses

• Synapse

• Axon

• Myelin sheath

• Cell body

The chemical secreted into the gap between neurons at a synapse

• Hormone

• Neurotransmitter

• Sense receptor

• Clorox

The nerve cell that transmits messages from the brain or spinal cord to a muscle or gland is a

• Motor neuron.

• Relay neuron.

• Sensory neuron.

• Interneuron.

The covering of fatty material that speeds up the passage of neural messages along the axon is the

• Myelin sheath.

• Synapse.

• Cell body.

• Soma.

The structure at the end of an axon that produces neurotransmitters to transmit the neural message across the synapse (synaptic gap) is the

• Dendrite.

• Myelin sheath.

• Axon.

• Axon terminal.

The nerve cell that carries messages from the environment from a sense receptor to the brain or spinal cord is a

• Motor neuron.

• Sensory neuron.

• Relay neuron.

• Interneuron.

The connection between adjacent neurons is the

• Synapse.

• Axon.

• Myelin sheath.

• Dendrite.
