| Term | Definition |
|---|---|
| The smallest living units of structure and function in the body are: | Cells |
| Homeostatic control occurs at different levels: | within the cell, from cell to cell within a tissue, and throughout the bod |
| Chemical reaction | interaction between two or more atoms that occurs as a result of activity between electrons in their outermost energy leve |
| Prostaglandins | 20-carbon unsaturated fatty acid containing 5-carbon ring |
| Cytoplasm | gel-like internal substance of cells that includes many organ-elles suspended in watery intracellular fluid called cytosol |
| Rough ER/Smooth ER | Two types of endoplasmic reticuluM |
| Cell structures | Plasma membrane/Cytoplasm/Nucleus |
| Osmosis | the movement of water through a semipermeable membrane, which prevents the passage of at least one solute |
| Simple diffusion | Molecules cross through the phospholipid bilayer Solutes permeate the membrane; therefore we call the membrane permeable |
| Passive transport processes | do not require any energy expenditure by the cell |
| Meiosis I | reduction division because the number of chromosomes is reduced by half (from the diploid number to the haploid number). |
| Principal types of tissue | 1. Epithelial tissue 2. Connective tissue 3. Muscle tissue 4. Nervous tissue |
| Structurally, there are five major types of bones | a. Long bones—cylindrical b. Short bones—boxlike c. Flat bones—broad, sheetlike d. Irregular bones—various shapes e. Sesamoid bones—seedlike |
| Syndesmoses | are joints in which fibrous bands (ligaments) connect two bones. |
