Week 1-5
| Term | Definition |
|---|---|
| Anatomy and physiology | Anatomy - defined as a study of the structure of an organism and relationship of its part, consists of gross and microscopic anatomy, Physiology - nature/words of study - deals with the functions of living organisms and its parts, |
| Anatomical directions | Superior - towards head / inferior - lower; below Anterior - front/ posterior - back Medial - towards midline/ lateral - towards side Proximal - towards the trunk/ distal- furthest from trunk Superficial- near surface/ deep - further from surface |
| Atoms | - electrons - (octet rule, chemical reactive)/ protons + (atomic number), neutrons no charge, (isotopes different neutrons than protons)/ atomic mass - neutrons plus protons weight. Ionic bond - transfer of e Covalent - sharing Hydrogen- polarity,weak |
| Metabolism | catabolism - breakdown into simpler molecules releasing energy/ hydrolysis - adding water to break Anabolism - joining simple molecules/dehydration synesthesis - water removal to make bigger molecules |
| Cells | Nucleus - DNA/nucleolus- makes ribosomes/ plasma membrane- protection,transportation/ ER - rough and smooth- protein synthesis, lipid addition, steroids, detox enzymes/ golgi- carb synthesis, glycoproteins/ vesicles- transport&storage/ lysosomes-digest ez |
| Tissue and surroundings | Epithelial - body cavities/ connective- support, connect, protect/ muscle- produce movement & heat/ nervous- communcation Endoderm, mesoderm, ectoderm ECM - collagen, elastin, gel-like surrounds cells |
| Tissue location and description | epithelial- membranous (surface) lines- serous cavities, blood and lymph vessels and all tracts, squamous, cuboidal, columnar, pseudostrat columnar Connective- fibrous, bone, cartilage, blood, Muscular - skeletal, striated voluntary, cardiac |
| skin | epidermis - basale, spinosum, granulosum, lucidum (clear), corneum (horny) Dermis -true skin, strength to skin, storage for water and electrolytes, arrest or pili, sweat glands, blood vessels Hypodermis - connection between skin and other structures |
| Bones | long bones -diaphysis - shaftlike, marrow/ epiphyses- ends, spongy, epiphyseal plate covered with hyaline cartilage Short bones - boxlike Flat bones - broad sheetlike Compact - dense and solid Cancellous - spongy |
| skeleton | axial - Includes all bones of he upright axis and head Appendicular - appendages and those bones |
