Stimulus And Response In Biology

An example of a stimulus is an individual placing a hand on a hot surface.

Stimulus and response in biology. It acts as an incentive or stimulant which arouses action which may either be negative or positive. The ability to respond to a stimulus is called irritability and is a necessary condition for life. Effector produces a response muscle.

Sensory neurone sends impulses to relay neurone. In most animals this job is done by the central nervous system cns. Stimulus is the change in environment which causes a change in activity or behaviour of an organism.

Effectors are organs in the body that bring about a response to the stimulus. The temperature is the stimulus and the individual then protects themselves. Stimulus a change in the environment internal or external that is detected by a receptor and elicits a response.

The main difference between stimulus and response is that a stimulus is an event or condition which initiates a response whereas response is the organism s reaction to a stimulus. Motor neurone sends impulses to effector. A biologic stimulus is any external change in the environment that can be detected by an organism.

The basic pathway for a nerve impulse is described by the stimulus response model. A stimulus is something in the. Every organism reacts to a stimulus in the form of some movements in the body.

Stimulus such as heat light cold pressure smell touch water and force of gravity. A stimulus is a change in the environment either external or internal that is detected by a receptor. A stimulus is any condition agent or action which incites a physiological or psychological activity causing a reaction or response.
