Stimulus Response Pathway

Homeostasis:

• is the process of maintaining a consistent and steady internal environment.

• allows for metabolic reactions to occur in our bodies.

• is required for all body systems to function correctly.

• is the process of maintaining a consistent and steady external environment.

The stimulus-response model:

• describes a series of steps followed when a change is introduced to the internal environment and if a response is required and how this will be corrected to achieve homeostasis.

• identifies the changes inside and outside your body.

• processes nerve impulse messages to determine which response is appropriate and sends message to the effector.

• are muscles and glands that receive messages from the central nervous system.

Receptors

• identify the changes inside and outside your body.

• process nerve impulse messages to determine which response is appropriate and sends message to the effector.

Effectors

• describe a series of steps followed when a change is introduced to the internal environment and if a response is required and how this will be corrected to achieve homeostasis.

• identify the changes inside and outside your body.

• process nerve impulse messages to determine which response is appropriate and sends message to the effector.

• are muscles and glands that receive messages from the central nervous system.

The stimulus-response system in our bodies is controlled by which system(s)?

• Nervous System

• Endocrine System

• Respiratory System

• Digestive System
