| Term | Definition |
|---|---|
| Metabolism | all chemical reactions in the body |
| Anabolism | building uo (synthesis, requires energy) |
| Epidermis | location-outermost layer of skin function- barrier against mechanical injury, pathogen, water loss contains keratinocytes, meloanocytes, Merkel cells, and langerhans cells |
| Dermis | Location-beneth the epidermis function- strength, elastically, sensation, thermoregulation -has a papillary layer (loose connective tissue, dermal papillae -reticular layer DENSE IRREGULAR CONNECTIVE Tissue |
| Acellular | made of tissue not cells |
| Golgi apparatus | modifies , packages, and sorts proteins/lipids into vessels |
| Plasma membrane | contains cholesterol (stability) and proteins (transport and receptors) |
| Cytoplasm | gel like fluid around the cells surrounds organelles, site of many chemical reactions |
| Gap Junctions | Location-lateral membranes between adjust cells looks like: tiny pores /tunnels function- allows passage of irons, nutrients, and signals between cells |
| Desmosomes | Location lateral surface of epithelial cells looks like spot like adhesions, linked to intermediate filaments function - mechanical strength COMMON IN SKIN AND HEART MUSCLE |
| Fibrocartilage | strongest type of cartilage |
| Neuron | conducting unit of nerve tissue |
| Acetabulum | location:lateral pelvic bone function: socket for femoral head ( hip joint) Looks like deep cup like depression |
| Intertbular groove | location- proximal anterior humorous function- passage for bicep tendens looks like greater tubercle (lateral) lesser tubule |
| true ribs | 1-7 and attach at the sternum |
