Anatomy and Physiology: Membranes Exam 2024/2025
Anatomy and Physiology: Membranes Exam 2024/2025 3 epithelial membranes ANS-cutaneous, mucous, serous Function of Body Membranes ANS-cover body surfaces, line body cavities, form protective sheets around organs Connective Tissue Membranes ANS-synovial membranes Cutaneous Membranes ANS-Skin; dry membrane, outermost protective boundary, superficial epidermis is composed of keratinized stratified squamous epithelium, underlying dermis is mostly dense connective tissue Mucous Membranes ANS-Surface epithelium type depends on site, stratified squamous epithelium (mouth, esophagus), simple columnar epithelium (rest of digestive tract), underlying loose connective tissue, lines all body surfaces/cavities that open to the exterior Serous Membranes ANS-Surface is a layer of simple squamous epithelium, underlying is a thin layer of areolar connective tissue, lines open body cavities that are closed to the exterior of the body, occur in pairs and separated by serous fluid visceral layer ANS-covers the outside of the organ parietal layer ANS-lines a portion of wall of ventral body cavity specific serous membranes ANS-peritoneum, pleura, pericardium peritoneum ANS-abdominal cavity pleura ANS-around lungs pericardium ANS-around the heart Synovial Membrane ANS-connective tissue only, lines fibrous capsules surrounding joints, secretes lubricating fluid Integumentary system ANS-skin (cutaneous membrane) mechanical barriers ANS-provided by the continuity of skin and the hardness of its keratinized cells chemica
