Coordination & Response Quiz

What is a stimulus?

• A signal transmitted by a neurone

• A change in the environment that triggers a response

• A chemical released by an effector

• An electrical impulse carried by an axon

Which of the following are effectors in the human body?

• Receptors and muscles

• Neurones and axons

• Muscles and glands

• Sensory neurones and motor neurones

What is the fastest method of communication between receptors and effectors?

• Hormones

• Nerves

• Reflex arcs

• Synapses

What are hormones a part of?

• Nervous system

• Endocrine system

• Peripheral nervous system

• Reflex arc

Which part of a neurone carries nerve impulses away from the cell body?

• Dendrites

• Synapse

• Axon

• Nucleus

What is the function of myelin?

• To produce neurotransmitters

• To increase the speed of nerve impulses

• To generate electrical signals

• To connect sensory and motor neurones

What is the role of the central nervous system (CNS)?

• To detect stimuli

• To coordinate messages within the nervous system

• To secrete hormones

• To produce neurotransmitters

What makes up the central nervous system?

• Brain and spinal cord

• Nerves and receptors

• Sensory neurones and relay neurones

• Synapses and neurotransmitters

What is a reflex arc?

• A pathway connecting the brain and spinal cord

• The sequence of sensory neurone, relay neurone, and motor neurone

• A type of effector

• A structure that slows down nerve impulses

What is the role of a sensory neurone?

• To send impulses to the CNS

• To transmit impulses between neurones

• To contract muscles

• To release hormones
