Document Summary
Ionic molecular cellular tissue organ system/organism. Limbs by side: body erect, eyes staring ahead, palms open, toes forward. Deep = below surface: terms referring to cavities. External = upon skin surface: muscle attachment (cid:858)origi(cid:374)(cid:859) = pro(cid:454)i(cid:373)al atta(cid:272)h(cid:373)e(cid:374)t (cid:858)i(cid:374)sertio(cid:374)(cid:859) = distal attachment, terms of motion. Flexion (- dist. between joint) / extension (+ dist. between joint) Adduction (towards body) / abduction (away from body) Inversion (sole of foot in) / eversion (sole of foot out) Protraction (joint drawn forward) / retraction (joint drawn backwards) Plantarflexion (toes up) / dorsiflexion (toes down: body cavities. Supra- = above: organisation of the body. Each cell has 3 main parts; plasma membrane (outer membrane), nucleus (contains nucleolus, chromosomes), cytoplasm (contains organelles: structure of the generalized cell, plasma membrane. Control entry and exit into cell: the cytoplasm. 3 major elements: cytosol (viscous, semitransparent fluid/gel, organelles (biological machinery e. g. endoplasmic reticulum) Inclusions (chemical substances e. g glycogen: the nucleus. Contains genes for cell replication, repair, division, protein synthesis.
