Physiology Week 1-6
| Term | Definition |
|---|---|
| Homeostasis | Relative constant state maintained by the body “state of balance.” |
| Negative feedback | Stabilize physiological variables. Produce an action that is opposite to the change that activated the system. Maintains homeostasis. |
| Positive feedback | Amplify or reinforce the change that is occurring. Disrupts homeostasis. |
| Three types of carbohydrates | 1. Monosaccharides (simple sugars) 2. Disaccharides (double sugars) 3. Polysaccharides (complex sugars) |
| Primary protein structure | sequence of a chain of amino acids |
| Secondary protein structure | hydrogen bonding of the peptide backbone causes the amino acids to fold into a repeating pattern. |
| Tertiary protein structure | three-dimensional folding patter of a protein due to side chain interactions. |
| Quaternary protein structure | protein consisting of more than one amino acid chain. |
| Catabolism | breaks molecules into smaller ones; usually releases energy. |
| Anabolism | builds large molecules from smaller ones; usually consumes energy. |
| Deoxyribonucleic acid (DNA) | A double-helix polymer that functions to transfer information, encoded in genes, to direct the synthesis of proteins. |
| Cell division phases | 1. Prophase “before phase” 2. Metaphase “position-changing phase” 3. Anaphase “apart phase” 4. Telophase “end phase” |
| Types of tissue | Epithelial, Connective, Muscle, Nervous |
| Primary layers of skin | epidermis and dermis |
| Types of bones | long bones, short bones, flat bones, irregular bones, sesamoid bones. |
| Axial skeleton | the 80 bones of the head, neck, and torso; composed of 74 bones that form the upright axis of the body and six tiny middle ear bones |
| Appendicular skeleton | the 126 bones that form the appendages to the axial skeleton; the upper and lower extremities |
| Cranial bones | frontal, parietal, temporal, occipital, sphenoid, ethmoid |
| Longest and heaviest bone in the body | Femur |
| Abduction | moves a part away from the median plane of the body |
| Adduction | moves a part toward the median plane of the body |
| Function of muscular system | Movement of the body as a whole or movement of its parts, heat procudtion, posture. |
