Biology · Neural Control and Coordination · NEET
NCERT defines coordination as the process through which two or more organs interact and complement the functions of one another. It does not mean one organ; it means organs working together as a team. Example: during exercise your muscles, lungs, heart, blood vessels and kidneys all adjust together.
If organs worked alone, they could not maintain homeostasis (a stable internal state). During exercise, muscles need more energy, so oxygen demand rises. This forces breathing rate, heart beat and blood flow to increase together. Only coordinated control keeps all these matched so the body stays balanced.
The neural system provides an organised network of point-to-point connections for quick coordination (fast, using nerve impulses). The endocrine system provides chemical integration through hormones (slower, but longer-lasting). NCERT says both jointly coordinate all body activities.
The neuron. NCERT says the neural system is made of highly specialised cells called neurons that can detect, receive and transmit different kinds of stimuli. Without neurons there is no point-to-point signalling, so no neural coordination.
No. Homeostasis is the goal (a stable internal environment). Neural coordination is one of the tools (fast nerve-based control) that helps achieve it, working alongside endocrine (hormonal) coordination. Do not treat them as synonyms in NEET assertion-reason questions.

It is fast, point-to-point control by neurons that makes organs work together to keep the body's internal state stable (homeostasis).
The neural system and the endocrine system jointly coordinate and integrate all activities of the organs so they work in a synchronised way.
Neural coordination uses electrical nerve impulses along a fixed point-to-point network, so messages reach the target almost instantly. Hormones travel in blood, which is slower.
During physical exercise, muscles, lungs, heart, blood vessels and kidneys adjust together (higher oxygen supply, breathing, heart beat and blood flow), then return to normal after exercise stops.
Yes. It is the opening concept of Neural Control and Coordination and sets up definitions (coordination, homeostasis, neural vs endocrine) that appear in assertion-reason and statement-based NEET questions.
