| Term | Definition |
|---|---|
| Homeostasis | the tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes. |
| positive feedback | Positive feedback is a process in which the end products of an action cause more of that action to occur in a feedback loop. This amplifies the original action. |
| intracellular control | mechanism operate at the cell level, regulates functions within the cell by means of genes and enzymes. |
| adenosine triphosphate (ATP) | a molecule that carries energy within cells. It is the main energy currency of the cell, and it is an end product of the processes of photophosphorylation cellular respiration, and fermentation. |
| glycogen | a substance deposited in bodily tissues as a store of carbohydrates. It is a polysaccharide which forms glucose on hydrolysis |
| hydrophobic | tending to repel or fail to mix with water. Literally means "fear of water". |
| electron transport system (ETS) | a series of biochemical steps by which energy is transferred in steps from a higher to a lower level. |
| cellular respiration | any of various energy-yielding oxidative reactions in living matter that typically involve transfer of oxygen and production of carbon dioxide and water as end products |
| meiosis | a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores |
| mitosis | a part of the cell cycle in which replicated chromosomes are separated into two new nuclei. |
| deoxyribonucleic acid (DNA) | is a biological macromolecule that carries hereditary information in many organisms. |
| connective tissue | tissue that connects, supports, binds, or separates other tissues or organs, typically having relatively few cells embedded in an amorphous matrix, often with collagen or other fibers, and including cartilaginous, fatty, and elastic tissues. |
| epithelial tissue | are thin tissues that cover all the exposed surfaces of the body. They form the external skin, the inner lining of the mouth, digestive tract, secretory glands, the lining of hollow parts of every organ, as well as the ventricular system. |
| endochondral ossification | a process where bone replaces cartilage. It occurs during fetal development and throughout childhood as the bones of the body grow. |
| axial skeleton | is a structure that provides attachment and support to the arms, legs as well as pectoral and pelvic girdles. |
| pelvic girdle | the enclosing structure formed by the pelvis, providing attachment for the hind limbs or pelvic fins. |
| dorsiflexion | bend (something, typically the hand or foot) dorsally or toward its upper surface. |
| elastic filament | refer mainly to titin, the largest of all known proteins. Titin was discovered initially in muscle cells, where it interconnects the thick filament with the Z-line. |
