Question

Quizplus · Accepted Answer

Dendrites are the highly branched part of the neuron that carries impulses towards the cell body.

B) Axon 
 Axon is a single, long extension of the neuron that carries impulses away from the cell body.

C) Astrocyte 
 Astrocytes are star-shaped glial cells that provide structural and metabolic support to neurons in the central nervous system.

D) Microglia 
 Microglia are a type of glial cell that act as the immune cells of the central nervous system, protecting neurons from damage or infection.

E) Schwann cell 
 Schwann cells are a type of glial cell that wrap around axons in the peripheral nervous system, providing insulation and support.

F) Interneuron 
 Interneurons are neurons that connect other neurons within the central nervous system, enabling communication between different parts of the brain or spinal cord.

G) Synaptic knob 
 Synaptic knobs are the small, bead-like structures at the end of the axon that release neurotransmitters into the synaptic cleft.

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

I) Synaptic cleft 
 The synaptic cleft is the small gap between the synaptic knob of one neuron and the dendrite or cell body of another neuron.

J) Enkephalins 
 Enkephalins are a type of neuropeptide that act as a natural painkiller in the body.

K) Oligodendrocyte 
 Oligodendrocytes are a type of glial cell that wrap around axons in the central nervous system, providing insulation and support.

L) Afferent neuron 
 Afferent neurons, also known as sensory neurons, transmit information about external stimuli from the body to the central nervous system.

M) Saltatory conduction 
 Saltatory conduction is the process by which a nerve impulse travels quickly and efficiently down a myelinated axon, "jumping" between the nodes of Ranvier.

N) Efferent neurons 
 Efferent neurons, also known as motor neurons, transmit information from the central nervous system to muscles or glands in the body.

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

P) Neurotransmitter 
 Neurotransmitters are chemical messengers that transmit signals between neurons, muscles, or glands in the body.

Q) Nodes of Ranvier 
 Nodes of Ranvier are the gaps in the myelin sheath surrounding an axon, where the axon is exposed and nerve impulses can "jump" between the nodes in saltatory conduction.
