Term | Definition |
---|---|
Mitochondria | power house of the cell |
sagittal | cuts the body vertically into left and right pieces |
organism | all the body systems make up an organism |
superficial | close to the body surface |
tissue | composed of similar types of cells and performs a specific function |
rough ER | covered with ribosomes; site of protein synthesis |
lateral | away from the middle |
cell wall | rigid, protective barrier (maintains cell shape) |
columar | cell with a high surface area to volume ratio as a result of finger-like projections on the surface (microvilli). |
Distal | farther from the trunk or attachment point |
Transverse | Divides the body into superior and inferior portions |
Nervous tissue | Supporting cells and connective tissue containing blood vessels may be associated with the neurons. |
Skeletal system | protects body parts, produce blood cells, stores calcium & phosphorus salts |
Prone | Body laying face down |
Coronal | Divides body into anterior and posterior sections |
Negative feedback | returns a variable back to a the set point |
Stratified | two or more layers |
Ribosomes | a minute particle consisting of RNA and associated proteins found in large numbers in the cytoplasm of living cells. They bind messenger RNA and transfer RNA to synthesize polypeptides and proteins. |
Organelle | tiny structures found in cells that perform cellular functions |
Physiology | the function of a part |
Stem Cells | Regulation of gene expression determines what cell type will develop from a totipotent embryonic cell |
Digestive System | receive food and digest into nutrient molecules |
Cuboidal | roughly cube-shaped |
Parasagittal | a cut that does not pass through the midline |
Homeostasis | balance |
Chloroplast | absorb light, which is the catalyst for photosynthesis. |
Supine | Body laying face up |
Hematopoiesis | describes the production of blood cells. |
Integumentary system | protects tissue, regulate body temperature & contains sense organs |
Connective tissue | bind other structures together and provide support, and protection against damage, infection, or heat loss. |
Nucleolus | makes ribosomes |
Cell | basic unit of all living things |
Dorsal | towards your back |
Lysosome | Trash Disposal of the cell |
Central vacuole | usually in plant cells |
Positive feedback | mechanism that brings about an ever greater change in the same direction |
Inferior | below something else |
Squamous | flat |
Multicellular | made up of many cells |
Epithelial | rapid absorption of nutrients into the blood. |
Pseudostratified columnar epithelium | type of simple epithelium that appears layered because the cells are of different heights. |
Organ | groups of tissues working together to perform a specific functionl |
Anatomy | the structure of a part |
Endocrine system | secretes chemicals that are messengers between body part, maintain proper functioning of reproductive system |
