The Human Nervous System Quiz

What are the two main parts of the human nervous system?

• Central nervous system and peripheral nervous system

• Brain and heart

• Spinal cord and muscles

• Nerves and blood vessels

What is the function of sensory neurones?

• Transmit impulses within the CNS

• Carry impulses from sense organs to the CNS

• Connect sensory and motor neurones

• Carry impulses from the CNS to effectors

What is the main long fibre of a neurone called?

• Dendrite

• Axon

• Node

• Myelin

What is the role of the myelin sheath?

• To connect neurones

• To insulate the axon

• To detect stimuli

• To produce electrical impulses

Which type of neurone is found inside the CNS?

• Sensory neurone

• Motor neurone

• Effector neurone

• Relay neurone

What is the correct pathway of an impulse through the nervous system?

• Effector → Motor neurone → Relay neurone → Sensory neurone → Stimulus

• Stimulus → Sensory neurone → Relay neurone → Motor neurone → Effector

• Relay neurone → Sensory neurone → Motor neurone → Effector → Stimulus

• Motor neurone → Effector → Stimulus → Sensory neurone → Relay neurone

What is the function of motor neurones?

• To insulate the axon

• To detect stimuli

• To carry impulses from the CNS to effectors

• To connect sensory and relay neurones

What is a bundle of neurones called?

• Nerve

• Dendrite

• Node

• Axon

What is the role of dendrites in a neurone?

• To insulate the axon

• To connect to other neurones and receive impulses

• To carry impulses to effectors

• To produce electrical impulses

What is the function of the central nervous system?

• To act as a central coordinating centre for impulses

• To carry impulses from sense organs to the CNS

• To insulate the axon

• To detect stimuli
