Dendrites

Front

Somatic nerves innervate which type of muscle?

Back

Skeletal muscle

Front

What is the function of Schwann cells?

Back

To form the myelin sheath around axons in the peripheral nervous system.

Front

What is the role of the myelin sheath?

Back

To insulate axons and increase the speed of nerve impulse transmission.

Front

What are the Nodes of Ranvier?

Back

Gaps in the myelin sheath that facilitate rapid conduction of impulses.

Front

What is the function of the axon terminal?

Back

To release neurotransmitters into the synaptic cleft.

Front

What is the difference between sensory and motor neurons?

Back

Sensory neurons transmit signals to the central nervous system, while motor neurons transmit signals from the central nervous system to muscles.

Front

What is the role of the central nervous system?

Back

To process and integrate information from the body and coordinate responses.
