| Medial | Toward the midline of the body. |
| Osteoporosis | Bones lose mass and can change structure, causing a metabolic disorder. |
| Osteomyelitis | Bacterial infection of bone and marrow; difficult to treat due to decreased blood supply and increased density; associated with other infections or direct bone contamination. |
| Stratum Corneum (horny layer) | Several layers of flakelike dead cells (or coenocytes) mostly made up of dense networks of keratin fibers cemented by glycophospholipids and forming a tough, waterproof barrier; the keratinized layer: a, sulcus (groove) b, friction ridge. |
| Dermoepidermal junction (DEJ) | The basement membrane, a unique and complex arrangement of adhesive components that glue the epidermis and dermis together. |
| Muscle cells | Structural features: Elongated, threadlike; contain tiny fibers that slide together forcefully. Function: Contract (shorten) to allow movement of body parts. |
| Cytoskeleton | Support framework of the cell and its organelles; functions in cell movement (using molecular motors); forms cell extensions (microvilli, cilia, flagella). |
| Ionic (electrovalent) | Transfer of electrons; strong electrostatic force; can dissociate in aqueous solution. |
