Week 1-5
| Term | Definition |
|---|---|
| Cervical Vertebrae | C1-C7; located in the neck. C1 and C2 are known as the Atlas and Axis, respectfully. |
| Thoracic Vertebrae | T1-T7; located in the posterior part of the chest, or the thoracic region. |
| Lumbar Vertebrae | L1-L5; located in the lower back and support the small of the back. |
| Sacrum | Directly below the lumber vertebrae; in infants, the sacrum is 5 separate vertebrae (S1-S5); at age 18 the vertebrae begin to fuse together and by age 25-33 are fully fused. |
| Coccyx | Directly below the sacrum; 3-5 tiny "tail" vertebrae that fuse to form the single coccyx by early adulthood. |
| Evaporation | Evaporating any fluid; important method of heat loss at high environmental temperatures when it is the only method by which heat can be lost from the skin. At moderate temperatures, evaporation accounts for about half as much heat loss as radiation. |
| Radiation | Transfer of heat from one object to another without actual contact; important method of heat loss in cool environmental temperatures. In cool temperatures, radiation accounts for a greater percentage of heat loss than conduction and evaporation combined. |
| Conduction | Transfer of heat to any substance actually in contact with the body; accounts for relatively small amounts of heat loss. |
| Convection | Transfer of heat away from a surface by movement of air; usually accounts for small amount of heat loss. |
| Prophase | "Before phase"; after cell has prepared for reproduction the nuclear envelope falls apart, chromatids coil up foil up to form chromosomes that are joined at the centromere. |
| Metaphase | "Position-changing phase"/"In-the-middle phase"; chromosomes align the equatorial plane, with one chromatid of each chromosome facing its respective pole. |
| Anaphase | "Apart phase"; the centromere of each chromosome splits to form two chromosomes, each consisting of a single DNA molecule. Each chromosome is pulled toward nearest pole, forming two separate but identical genetic pools. |
| Telophase | "End phase"; DNA returns to original form and location in the cell; after telophase completion, each daughter cell begins interphase to develop into mature cell. |
