Control and Coordination — Important Questions

Detecting changes in environment, Controlling reflex actions, Coordinating voluntary movements, Processing information in the brain

The nervous system detects environmental changes through receptors, controls reflex actions, coordinates voluntary movements, and processes information in the brain. Producing digestive enzymes is a function of the digestive system, not the nervous system.

True

True. Reflex actions are quick, automatic responses that occur at the spinal cord level without involving the brain. This makes them faster than voluntary actions that require brain processing.

Cytokinin

Cytokinins promote cell division and are found in high concentrations in areas of rapid cell division like fruits and seeds. The name 'cytokinin' comes from 'cytokinesis', which means cell division.

Writing, Talking, Clapping hands

Voluntary actions are those we consciously control and decide to perform, like writing, talking, and clapping. Heart beating and breathing during sleep are involuntary actions controlled by the medulla.
