Control And Coordination Class 10 Notes Summary

Control and coordination are basic but crucial activities that help living things react properly to changes around them and inside them.

These activities are necessary for all living things to stay alive and function well, from simple organisms like bacteria to complex ones like humans. Control and coordination make sure an organism acts in ways that fit its situation by bringing together signals and managing reactions.

Living beings manage control and coordination through two main systems: the nervous system and the endocrine system. They work both on their own and together to keep balance in the body, respond to things around them, and help with growth and development.

The Nervous System: This system gives quick control and coordination. It includes the central nervous system (CNS), made up of the brain and spinal cord, and the peripheral nervous system (PNS), made of nerves and sensory organs.

The CNS figures out what to do with information, and the PNS sends messages to and from the CNS, helping the organism notice and respond to its surroundings. Nerve cells, or neurons, are the key parts of the nervous system, sending electrical and chemical signals all over the body.

The Endocrine System: This system controls things more slowly but the effects last longer, using hormones. Hormones are chemicals sent into the blood that affect different parts of the body.

The endocrine system manages growth, energy use, and reproduction. It includes glands like the thyroid, adrenal, and pituitary, which release hormones to regulate various body functions.

The cooperation between the nervous and endocrine systems makes sure organisms can react well to quick changes and long-term challenges. For instance, reacting to danger involves quick actions by the nervous system and slower hormonal adjustments by the endocrine system.

Feedback mechanisms are key for managing control and coordination. Negative feedback loops keep the body stable by fixing any changes from the normal state.

For example, controlling blood sugar involves hormones that either raise or lower blood glucose as needed. Positive feedback loops, though rarer, make responses stronger, like the increase of oxytocin during childbirth to make labor contractions stronger.
