| Question | Answer |
|---|---|
| The study of structure | Anatomy |
| The study of function | Physiology |
| Defined as the ability of an organism to maintain internal conditions favorable to life despite chage in external environment | Homeostasis |
| Control of Homeostasis | 1. Receptors (baro, chemo, mechano) 2. Interpretations/Control Center 3. Effectors (muscles, glands) |
| Most homeostatic control is this type of feedback | Negative Feedback |
| Feedback that generally works to oppose an original stimulus | Negative Feedback |
| This type of feedback control and prevents sudden changes in the body that may be severe | Negative Feedback |
| This type of feedback works to accelerate an original stimulus frequently causing cascade | Positive Feedback |
| This type of feedback moves in the same direction | Positive Feedback |
| above | Superior |
| below | Inferior |
| front/belly side | Ventra |
| back (like the dorsal fin of a dolphin) | Dorsal |
| toward the center | Medial |
| away from the center | Lateral |
| closer to the origin or attachment | Proximal |
| farther from the origin or attachment | Distal |
| away from the body surface | Deep |
| toward the body surface | Superficial |
| Runs longitudinally cutting the body into right and left halves | Sagittal Plane |
| Runs longitudinally, but the body or organs are divided into anterior and posterior | Frontal Plane (coronal) |
| Runs horizontally across and at a right angle to the long axis of the body or organ and divides it into superior and inferior parts | Transverse Plane |
| Lines the walls of the body cavity | Parietal serosa |
| Covers the organs of the cavity | Visceral serosa |
