Term | Definition |
---|---|
Anatomy | the study of structure, mostly names and terminology |
Physiology | the function |
Gross Anatomy | things big enough to see with the naked eye |
Microscopic Anatomy | things too small to see without a magnifying device |
Gross Surface Anatomy | what it looks like before you cut |
Gross Regional Anatomy | ALL parts in a certain area |
Gross Systemic Anatomy | ALL bones and ALL glands, pretending that there isn't anything else in the same area |
Cytology (Microscopic Anatomy) | the study of individual cells |
Histology (Micrroscopic Anatomy) | the study of tissue |
Tissues | groups of cells with a similar structure and a common general function |
Principal of Complementarity of Structure and Function | (Form Follows Function) things look the way they do because of the function they must perform |
Boundary Maintenance | 1. keeps inside separate from outside 2. regulates what moves across the boarder |
Digestion | taking larger substances and breaking them down into smaller, useful building blocks |
Excretion | actively removing waste material from inside to outside (think boundaries) |
Growth | getting bigger AND follows a patter |
Metabolis | 1. Boundary Maintenance + Digestion +Excretion + Growth 2. Often used when discussing a particular item or category |
Movement | ACTIVE (not passive) motion with a function or purpose |
Reproduction | Offspring |
Irritability (Responsiveness) | responsiveness to an external stimulus but the response has function for the organism |
Homeostasis | actively maintaining internal conditions within very narrow limits, despite large changes in external conditions |
Negative Feedback Loop (almost universal) | the action (effect) reduces the stimulus (affect) |
Positive Feedback Loop (rare) | 1. the action (effect) increases the stimulus (affect) 2. tends to break homeostasis and often requires a control mechanism external to the loop |
Diffusion | random movement of particles from regions of high concentration to regions of low concentration |
