Neuro Quiz KC level 2

What is the primary function of the central nervous system (CNS)?

• To transmit signals from the brain to the rest of the body

• To process and integrate information

• To detect changes in the environment

• To control voluntary muscle movements

Which of the following is a major component of the central nervous system?

• Spinal cord

• Sensory neurons

• Motor neurons

• Peripheral nerves

What is the main role of motor neurons?

• To detect sensory stimuli

• To transmit signals from the CNS to muscles

• To process information in the brain

• To connect sensory neurons to the CNS

Which part of the motor neuron receives signals from other neurons?

• Axon

• Dendrites

• Myelin sheath

• Synapse

What is the function of sensory neurons?

• To transmit signals from the CNS to muscles

• To process information in the brain

• To detect and transmit sensory information to the CNS

• To connect motor neurons to the CNS

Which of the following is a component of the peripheral nervous system (PNS)?

• Brain

• Spinal cord

• Cranial nerves

• Cerebellum

What is the primary function of the peripheral nervous system?

• To process and integrate information

• To transmit signals between the CNS and the rest of the body

• To control involuntary muscle movements

• To store memories

Which structure in a motor neuron is responsible for transmitting electrical impulses away from the cell body?

• Dendrites

• Axon

• Synapse

• Myelin sheath

What is the role of the myelin sheath in motor neurons?

• To receive signals from other neurons

• To transmit sensory information to the CNS

• To insulate the axon and speed up signal transmission

• To connect neurons to muscles

Which of the following best describes the structure of sensory neurons?

• They have long axons and short dendrites

• They have short axons and long dendrites

• They have a cell body located in the CNS

• They have multiple axons
