Document Summary

(cid:862)for(cid:373) follo(cid:449)s fu(cid:374)(cid:272)tio(cid:374)(cid:863) things look the way they do because of the function it does. The anatomy act: legislation regulating the use of human tissues for study. Levels of organization: molecular (interacting together gathered together in a lipid bilayer which are the cells that make up the body) cellular (cells form to make tissues) tissue (connective, nervous, epithelia, muscular) organ system. Anatomical terms: derived from greek, latin, english based on regions, shape, function, background story and the discoverer. Hypertonic: high salt solution water leaves the cell and the cells shrink. Isotonic: i(cid:374)side a(cid:374)d outside salt (cid:272)o(cid:374)(cid:272)ertatio(cid:374) is the sa(cid:373)e so it retai(cid:374)s its" (cid:374)or(cid:373)al shape. Hypotonic: low salt solution water enters the cell through the plasma membrane and lysis. Body mistakes: arm (brachium) is from shoulder to elbow and leg (crus) is knee to ankle. Coronal plane: any plane that cuts that divides the body into equal posterior and anterior. Sagittal plane:: any section that divides the body into half.
