Match the following components and processes of the human nervous system with their descriptions:

Nerve impulse = An electrical signal that travels along nerve cells Reflex arc = A rapid and automatic integration and coordination of stimuli with the responses of effectors Stimulus = Something that triggers a nerve impulse Motor neurone = Carries the response to the appropriate effector Signup and view all the answers

Match the following parts of the human nervous system with their functions:

Central nervous system = Processes the nerve impulse Peripheral nervous system = Consists of sensory and motor neurones Spinal cord = Part of the central nervous system Sensory neurone = Carries the impulse from the receptor to the central nervous system Signup and view all the answers

Match the following terms related to the human nervous system with their definitions:

Nervous system = Consists of nerve cells that transmit nerve impulses Effectors = Muscles and glands that respond to the nerve impulse Neurones = Nerve cells that carry the nerve impulse Response = Action or behavior that occurs as a result of the nerve impulse Signup and view all the answers

Match the following steps of a reflex action with their descriptions:

Stimulus = Triggers a nerve impulse Impulse is picked up by a = Sensory neurone Impulse is carried to the = Central nervous system Response to stimulus occurs = After the central nervous system processes the impulse Signup and view all the answers
