Neurons that conduct impulses to muscles and glands are classified as:

• Sensory neurons

• Motor neurons

• Interneurons

• Central neurons

Which part of a neuron is responsible for generating and transmitting nerve impulses?

• Soma

• Dendrites

• Axon

• Myelin sheath

The myelin sheath primarily functions to:

• Protect neurons from infection

• Decrease impulse transmission speed

• Electrically insulate and increase impulse transmission speed

• Store neurotransmitters for rapid release

Which structural classification of neurons has one process dividing into two branches?

• Multipolar

• Bipolar

• Unipolar

• Tripolar

The central nervous system (CNS) includes which of the following?

• Brain and spinal cord

• Brain and cranial nerves

• Spinal cord and peripheral nerves

• Brain and peripheral nerves

Dendrites are responsible for:

• Generating electrical impulses

• Receiving incoming signals

• Releasing neurotransmitters

• Protecting the neuron from damage

Which division of the nervous system includes the brain and spinal cord?

• Central nervous system

• Peripheral nervous system

• Autonomic nervous system

• Sympathetic nervous system

Which of the following neurons are most common in the human body?

• Bipolar

• Multipolar

• Unipolar

• Tripolar

Which part of the brain is responsible for smooth and coordinated movements?

• Cerebrum

• Brainstem

• Cerebellum

• Thalamus
