reaction time rp and homeostasis

function of a receptor

specialised cell which detects stimuli

independent variable

something you change in an experiment

receptors found in the skin

are responsible for sensing touch, temperature, and pain.

2 type of effectors

muscles which contract and glands which release hormones

reaction time

the duration it takes for a stimulus to elicit a response in an organism.

enzyme

a biological catalyst that speeds up chemical reactions in living organisms by lowering the activation energy.

denature

to alter the natural properties of an enzyme, often due to heat or pH changes, resulting in a loss of its biological activity.

organ

a group of tissues that work together to perform a specific function in the body.

homeostasis

the process by which living organisms regulate their internal environment to maintain stable, constant conditions despite external changes.

internal conditions

that organisms maintain for optimal functioning.

what does a receptor detect?

stimulus

where is information from the receptor sent to

the central nervous system (CNS) for processing.

what does the CNS do

Processes information and coordinates responses.

what does the effector do

produces the response ( makes the condition normal again)

what are receptors

Specialized cells that detect stimuli and convert them into neural signals.

what do receptors do

Receptors detect environmental changes and convert them into electrical impulses that the nervous system can interpret.

effectors

Effectors are muscles or glands that carry out responses to stimuli, helping to restore homeostasis.
