Important definitions to memorize for chapter 10 of the NASM FNS

Calcitonin ~ A hormone secreted by the thyroid gland in response to elevated blood calcium. It stimulates calcium deposition in bone and calcium excretion by the kidneys, therefore reducing the blood calcium concentration

Calmodulin ~ A calcium-binding protein that regulates a range of cellular activities, like cellular division and proliferation

Carotenodermia ~ A harmless yellow-orange cast to the skin because of high levels of carotenoids within the blood resulting from consumption of very large amounts of carotenoid-rich foods, like carrot juice

Carotenoids ~ are a group of yellow, orange, and red pigments in plants and foods. several of these compounds are precursors of vitamin A

Cells ~ the fundamental structural units of all living tissues, that have 2 major parts: the nucleus and the cytosol

Cornea ~ The clear outer surface of the eye

Epithelial Cells ~ The multimillion number of cells that line and shield the external and internal surfaces of the boy. Epithelial cells form epithelial tissues like skin and mucous membranes.

Epithelial Tissues ~ Closely packed layers of epithelial cells that cowl the body and line its cavities

Glutathione ~ A tripeptide of glycine, cysteine, and glutamic acid that is involved in the protection of cells from oxidative cellular damage

Night-Eating Syndrome (NES) ~ a disorder of eating during which a habitual pattern of interrupting sleep to eat is the primary symptom

Opsin ~ A protein that mixes with retinal synthesize rhodopsin in rod cells

Orexin ~ a kind of hormone in the brain that may affect food consumption

Osteoblasts ~ Bone cells that promote human bone deposition and growth

It stimulates calcium ion release from bone and calcium absorption by the intestines, whereas decreasing calcium ion excretion by the kidneys. It acts in conjunction with 1.25(OH)2D3 to lift blood calcium ion concentration. Additionally known as parathormone-1

Phylloquinone ~ is the form of vitamin K (naphthoquinone) that comes from plant sources. Additionally referred to as vitamin K1(phylloquinone)
