Nervous System

Front

What do sensory neurons do?

Back

Sensory neurons carry nerve impulses from the sense organs and internal organs to the central nervous system (CNS).

Front

What is the function of the myelin sheath?

Back

The myelin sheath improves the conductivity of nerve impulses along the axon.

Front

What type of neuron processes transmit information from sensory organs to the CNS?

Back

Afferent neurons transmit information from sensory organs to the central nervous system.

Front

What part of the nervous system regulates involuntary actions?

Back

The Autonomic Nervous System regulates involuntary actions such as heart function, blood pressure, breathing, and digestion.

Front

What do sensory neurons carry signals from?

Back

Sensory neurons carry signals from tissues and organs to the brain and spinal cord.

Front

What is the central nervous system (CNS)?

Back

The central nervous system consists of the brain and spinal cord, processing information and coordinating responses.

Front

What are motor neurons responsible for?

Back

Motor neurons carry signals from the CNS to muscles and glands, enabling movement and responses.

Front

What is the role of glial cells?

Back

Glial cells support and protect neurons, providing structural support and insulation.

Front

What is the difference between afferent and efferent neurons?

Back

Afferent neurons carry signals to the CNS, while efferent neurons carry signals away from the CNS to effectors.

Front

What is the function of the peripheral nervous system (PNS)?

Back

The peripheral nervous system connects the central nervous system to the limbs and organs, facilitating communication.
