Coordination

Answer

Coordination is the process by which different body parts and organs work together in a proper way to produce a response. It helps in movement, balance, and control of body activities.

Answer

These activities need many body parts to work together at the same time. Muscles, nerves, and brain regions coordinate movement and posture so the body can act smoothly and stay balanced.

Answer

A stimulus is a change in the surroundings or inside the body that causes a response. Examples include light, touch, heat, sound, and chemicals.

Answer

A response is the action shown by an organism after receiving a stimulus. For example, withdrawing the hand from a sharp object or bending a plant toward light.

Answer

A neuron is a nerve cell and the structural and functional unit of the nervous system. It has a cell body, dendrites, and an axon, and it helps in carrying messages through the body.

Answer

A neuron has a cell body, dendrites, and an axon. Dendrites receive signals, the cell body contains the nucleus, and the axon carries the message away from the cell body.

Answer

A synapse is the functional region of contact between two neurons. It is a tiny gap where information passes from one neuron to another by chemical or electrical signals.

Answer

Dendrites of one nerve cell connect to the axons of another nerve cell through synapses. This connection helps messages move from one neuron to the next.
