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 |
