Control and Coordination Mind Map

A stimulus is any change in the surroundings or inside the body that can be detected and can produce a response.

In answers, always write the change first, then the body part that detects it, and finally the response. This keeps the sequence correct.

A neuron is a nerve cell that carries messages in the body in the form of electrical impulses.

When asked about a neuron, mention both structure and function. A neat label of dendrite, cell body, and axon often adds marks.

A synapse is the small gap between two neurons, or between a neuron and an effector, where the message passes from one cell to another.

If a question asks how impulses move from one neuron to another, mention neurotransmitters and the synaptic gap.

A reflex action is a quick, automatic response to a stimulus, usually controlled by the spinal cord for safety.

If the question says quick, automatic, and protective, think of reflex action and the reflex arc.
