Question

Quizplus · Accepted Answer

An interneuron connects sensory and motor neurons in a reflex arc.

Answer: G
 The synaptic knob is the small swelling at the end of an axon that releases neurotransmitters into the synaptic cleft.

Answer: H
 Serotonin is a neurotransmitter that is involved in regulating mood, appetite, and sleep.

Answer: I
 The synaptic cleft is the gap between the synaptic knob and the dendrite or cell body of the next neuron.

Answer: J
 Enkephalins are neurotransmitters that are involved in reducing pain sensation.

Answer: K
 Oligodendrocytes are a type of glial cell that produce myelin in the central nervous system.

Answer: L
 Afferent neurons transmit sensory information from the senses to the central nervous system.

Answer: M
 Saltatory conduction is the rapid movement of an action potential along a myelinated axon, jumping from node to node.

Answer: N
 Efferent neurons transmit motor impulses from the central nervous system to muscles and glands.

Answer: O
 The cell body is the main part of the neuron that contains the nucleus and other organelles.

Answer: P
 Neurotransmitters are chemical messengers that transmit signals from one neuron to another.

Answer: Q
 The nodes of Ranvier are the small gaps in the myelin sheath of an axon where there is no insulation.
