Term | Definition |
---|---|
Body Cavities | 1. Dorsal: cranial and spinal cavities 2. Ventral: thoracic and abdominopelvic |
Chemical Reactions | 1. synthesis- creates new product 2. decomposition- releases energy from breakdown 3. exchange-reactants exchange and create 2 new products |
Acids/bases | Acids: turn litmus red, release H+ ions in a solution, H+ concentration determines acidity level Bases: blue litmus, proton acceptor, more OH- ions |
Cell connections | 1. desmosomes- interlock adjacent cells, intermediate filaments ex. skin cells, belt type encircles like adhesive 2. Gap junctions- membrane channels of plasma connect,fuse membranes Ex. heart muscle 3. Tight junction- joined by membrane collars. |
Tissue types | 1. epithelial (membraneous glandular) 2. connective(fibrous, bone, cartilege, blood) 3. muscle (skeletal, smooth, cardiac) 4. nervous made of collagen, reticular fibers and elastin |
Epithelial membranes | 1. cutaneous 2. serous 3. mucus |
Connective Tissue membranes | 1. synovial, no epithelials |
Bone types | 1. compact 2. cancellous |
Bone shapes | 1. long bones 2.short 3. flat 4. irregular 5.seasamoid (patella) |
Skeletal structure | 1. axial: skull, hyoid, verterbral column, sternum/ribs 2: appendicular: upper and lower extremities including pelvic girdle |
Ribs | True ribs: 1-7 pairs: join sternum with costal cartilage False ribs: 5 pairs- indirect sternum attachment 8,9,10 to ribs above, floating dont attach to sternum. |
Vertebral column | cervial (7) thoracic (12) lumbar (5) + sacrum and coccyx |
