Document Summary
Lateral folding: creating an interactive and supportive body tube: Tube within a tube body plan: body tube, evolution: visceral somatic tube, neural tube, blood tubes, gut tube, respiratory tubes, urinary tubes, reproductive tubes. Tube of ectoderm which covers everything: has a lining of mesoderm on the inside of it (somatic tube) holds visceral tubes. The skin (in terms of evolution) is very important gives us a barrier of protection and a way of interacting. Coloured in pink gives us our dermis and hypodermis (supporting connective tissue to skin: hypodermis can be written as subcutis. Combination of se and lp-m gives us the. Epidermal appendages they grow from the epidermis but can be found in the dermis: hair follicles, nails. Keratinised, stratified squamous epithelium with basil laminar keratinocytes undergoing keratinisation: classified based on surface layer shape (apical layer, avascular (no blood vessels) thick skin (on palms and soles) and thin skin. Epidermal thickness: thick skin: ~1mm thin skin ~0. 1mm.
