Understanding Nervous System and Neurons

Which part of the neuron receives signals from other neurons?

• Axon

• Dendrite

• Myelin sheath

• Synapse

What is the main function of the peripheral nervous system?

• To process information in the brain

• To connect the central nervous system to the rest of the body

• To protect the spinal cord

• To produce hormones

Which structure carries nerve impulses away from the cell body?

• Dendrite

• Axon

• Nucleus

• Soma

What are the two main parts of the nervous system?

• Brain and spinal cord

• Central and peripheral nervous systems

• Neurons and glial cells

• Axons and dendrites

Which part of the neuron contains the nucleus?

• Axon terminal

• Cell body (soma)

• Dendrite

• Myelin sheath

What is the function of the myelin sheath?

• To receive signals from other neurons

• To speed up the transmission of nerve impulses

• To connect neurons to muscles

• To store neurotransmitters

Which of the following is NOT a part of a neuron?

• Dendrite

• Synapse

• Muscle fiber

The central nervous system is made up of the:

• Brain and spinal cord

• Nerves and ganglia

• Heart and lungs

• Muscles and bones

Which part of the peripheral nervous system controls voluntary movements?

• Autonomic nervous system

• Somatic nervous system

• Central nervous system

• Endocrine system

What is the gap between two neurons called?
