Question

Quizplus · Accepted Answer

The synaptic knob is the part of the axon that releases neurotransmitters.

Answer: P
 A neurotransmitter is a chemical substance released by the synaptic knob that transmits nerve impulses across a synapse.

Answer: I
 The synaptic cleft is the narrow gap between the synaptic knob and the dendrite of the receiving neuron.

Answer: M
 In saltatory conduction, the action potential jumps from node to node along the myelinated axon, which results in faster transmission of the signal.

Answer: E
 Schwann cells are specialized cells that form the myelin sheath around axons in the peripheral nervous system.

Answer: O
 The cell body, also known as the soma, is the part of the neuron that contains the nucleus and other organelles.

Answer: L
 Afferent neurons, also known as sensory neurons, carry information from sensory receptors to the central nervous system.

Answer: N
 Efferent neurons, also known as motor neurons, carry information from the central nervous system to muscles and glands.

Answer: A
 Dendrites are short, branched processes of the neuron that receive signals from other neurons or sensory receptors.

Answer: B
 The axon is the long, thin process of the neuron that transmits signals away from the cell body and towards other neurons or target cells.

Answer: C
 Astrocytes are a type of glial cell that support and nourish neurons, as well as maintain the blood-brain barrier and regulate the environment around neurons.

Answer: D
 Microglia are a type of glial cell that act as immune cells in the nervous system, defending against pathogens and removing debris from injured or dead cells.

Answer: F
 Interneurons, or association neurons, are neurons that connect different neurons within the central nervous system, allowing for complex processing and integration of information.

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

Answer: J
 Enkephalins are a type of endorphin, a class of neurotransmitters that act as natural painkillers in the body.

Answer: K
 Oligodendrocytes are a type of glial cell that form the myelin sheath around axons in the central nervous system.

Answer: Q
 Nodes of Ranvier are the gaps between adjacent segments of myelin on an axon, where the action potential is regenerated.
