| Peroxisomes | Round circular, makes enzymes that oxidize toxic chemicals |
| Lysosome | produces powerful enzymes that aid in digestion and excretion of substances |
| periosteum | thin, fibrous membrane covering entire bone surface |
| hyaline cartilage | dense collagen fibers make this cartilage extra tough, covers bone ends, attaches ribs to sternum |
| sternocleidomastoid | twist and tilts the neck |
| mentalis | raises the lower lip and wrinkles chin |
| perimysium | connective tissue sheath surrounding a fascicle |
| sarcoplasm | cytoplasm of muscle cell containing many nuclei |
| stratum corneum | Several layers of flakelike dead cells mostly made up of dense networks of keratin fibers cemented by glycophospholipids and forming a tough, waterproof barrier; |
| stratum granulosum | 2-5 layers of dying, somewhat flattened cells filled with darkly staining keratohyalin granules and multilayered bodies of glycophospholipids |
| stratum basale | Single layer of mostly columnar cells capable of mitotic cell division |
| diaphysis | main shaftlike portion of bone, hollow cylindrical shape |
| epiphyses | the proximal and distal ends of a long bone |
| osteoclast | giant multinucleate cells re-sponsible for the active erosion of bone minerals |
| bases | alkaline compounds that when dissociated in solution, shift the H/OH balance in favor of OH |
| peptide bond | one that binds the carboxyl group of one amino acid to the amino group of another amino acid |
