Document Summary

The outermost layer is the skin itself. Last term we talked about epidermis, etc. the epidermis a(cid:374)d the de(cid:396)(cid:373)is de(cid:396)(cid:373)is itself (cid:894)i(cid:374) (cid:374)otes(cid:895) is (cid:395)uite i(cid:374)(cid:448)ol(cid:448)ed (cid:449)ith (cid:271)lod suppl(cid:455), (cid:272)apilla(cid:396)ies. The c of the scalp represents the hypodermis. The dermis itself has all the sebaceous, oil and sweat glands. Has hair follicles, lots of circulation and nerves. The (cid:272)lose su(cid:271)(cid:272)uta(cid:374)eous tissue, a(cid:396)eola(cid:396) tissue is h(cid:455)pode(cid:396)(cid:373)is. Third layer, is the thicker one, aponeurosis. The gala aponeurotica which is basically the apo(cid:374)eu(cid:396)osis of the . This tissue will allow for the top 3 layers to move separately on the bone. Within the collagen and elastin, can move in diferent die(cid:272)tio(cid:374)s a(cid:374)d (cid:374)ot (cid:271)e da(cid:373)aged.
