Anatomy and Physiology Basics

serous membranes or serosa ar thin, but obvious membranes that line a body orchestra pit much(prenominal) as the ab and thoracic cavities; as well as application curriculum the revolution meat that lie in that cavum. Serous membranes live of connectedness wander, covered by mesothelium. Serous membranes have deuce layers: the parietal layer and the visceral layer. The parietal layer lines and attaches to the cavity wall. The visceral layer covers and sticks to the organs within a cavity. Serous fluid, which is produced by the mesothelium, is a watery lubricating fluid that reduces friction by allowing organs to slide over each other, or against the cavity wall. constituent(a) proteins atomic number 18 protein molecules that are ext cobblers lasted thru a cellular call back membranes lipid bi-layer, and are firmly insert in it. They are also referred to as transmembrane proteins because one end sticks verboten in the extracellular fluid, and the other in a c ells cytosol. Integral proteins can serve a variety of roles much(prenominal) as : a. Ion channels-pores through which a proper(postnominal) ion such as potassium can flow in or out of a cell. b. Carriers- process by which a arctic substance or ion is moved from one side of a membrane to the other. c. Receptors- the ability of each type of receptor to hear and bine to a particular(prenominal) type of molecule. d.

Enzymes- proteins that catalyze specific chemical reactions at the inside or outside a cells surface. e. Linkers- anchors proteins in the plasma membrane of next cells to each other, or protein filaments in and out of the cell. f. Ident! ity markers- enables a cell to recognize other cells of the same kind during interweave formation, or to recognize and respond to a foreign cell. The tercet major modes of transport across the cell membrane are diffusion, osmosis, and active transport. Three types of connective tissue are: embryonic, break and dense tissue. Connective tissue is fibrous tissue that is widely distributed and abundant in the body. It has a variety of functions such as to bind...If you want to get a full essay, order it on our website: OrderCustomPaper.com
