What is Homeostasis? Give examples.
It is the maintenance of a constant internal environment.
ex. Body Temp., HR, BR.
What is the set point of Homeostasis? Give examples.
The ideal or normal value of blood pressure and body temp.
ex. 120/80 for BP or 98.6 degrees (37 degrees C) for body temp.
What is negative feedback?
A mechanism that regulates Homeostasis and it is good for you.
What are the components of negative feedback?
The control center, receptor, and effector.
What is a positive feedback?
It is a deviation from set point and becomes greater. It makes a situation worse and is rarely found in healthy people.
What are the directional terms? What do they mean?
Superior means above, Inferior means below, Anterior means front, and Posterior means back. Medial means close to the midline, and Lateral means away from the midline. Proximal means close to the point of attachment, and Distal means far from the point of attachment. Superficial means close to the surface, and Deep means toward the interior of the body.
