The body's mainenance of a stable internal enviornment.

They are self-regulating control systems of the body that help to maintian homestasis.

• 1. Receptors - provides information about the stimuli
• 2. Control Center - tells what a particular value should be (called a set point)

3. Effector - elicits responses that change conditions in the internal enviornment


> could put Figure 1.6 in here from page 10

It is the "thermostat"-sensitive region in a control cent of the brain.

A process that moves conditions towards the normal state.

The most common type of feedback mechanism (loop).

Example: body temperature, blood pressure, glucose regulation

A process that moves conditions away from the normal state.

example: blood cloting and child birth

• A lengthwise cut that divides the body into left and right portions.

[A length wise cut that divides the body into equal left and right portions]

• When a sagittal section passes along the midline and divides the body into equal parts.

[A length wise cut that divides the body into equal left and right portions]

• A sagittal section lateral to midline is called parasagittal.
