• Spinal cord and muscles

• Nerves and blood vessels

• Brain and heart

• Central nervous system and peripheral nervous system

What is the function of sensory neurones?

• To detect stimuli and send impulses to the CNS

• To produce hormones

• To carry impulses from the CNS to effectors

• To connect sensory and motor neurones

What is a bundle of neurones called?

• A gland

• A nerve

• A receptor

• A synapse

Which part of the nervous system acts as a coordinating center?

• Endocrine system

• Central nervous system

• Muscular system

• Peripheral nervous system

What is the role of a relay neurone?

• To detect stimuli

• To carry impulses to effectors

• To connect sensory and motor neurones

• To produce electrical impulses

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

• Effector → sensory neurone → relay neurone → motor neurone → stimulus

• Stimulus → sensory neurone → relay neurone → motor neurone → effector

• Stimulus → motor neurone → relay neurone → sensory neurone → effector

• Effector → motor neurone → relay neurone → sensory neurone → stimulus

What is an effector in the nervous system?

• A type of neurone

• A sensory receptor

• A muscle or gland that carries out a response

• A part of the brain

What type of signals are transmitted through the nervous system?

• Chemical signals

• Electrical impulses

• Magnetic waves

• Sound waves

Which of the following is NOT part of the central nervous system?

• Peripheral nerves

• Spinal cord

• Brain

• Cerebellum

What is the primary function of the central nervous system?

• To coordinate and process information

• To transport blood

• To produce hormones

• To digest food
