| Term | Definition |
|---|---|
| Contractibility | When applied to muscles, is meant in a broad sense of pulling the ends together regardless of whether the cell actually gets shorter |
| Splicesomes | The noncoding intron segments of the mRNA initially transcribed from a DNA gene are removed by a complicated process involving small structures |
| Macromolecules | Molecules, in turn, often combine with other atoms and molecules to form larger and more complex chemicals |
| Fascia | Fibrous connective tissue surrounding the muscle organ and lo-cated outside the epimysium and tendon |
| Set Point | Normal reading or range of normal |
| Integumentary | Separates internal environment from external environment, providing stability of internal fluid volume |
| Skeletal | Supports and protects internal environment, allowing movement; stores minerals that can be moved into and out of internal fluid |
| Integrator | Control center of the feedback loop. Often a discrete area of the brain, the integrator receives input from a homeostatic sensor. |
| Hypothalamus | When cold weather causes the body temperature to decrease, feedback information is relayed through the nerves to the “thermostat” in a part of the brain |
| Oxytocin | Information regarding increased stretch is fed back to the brain, which triggers the pituitary gland to secrete a hormone |
