BIOL 240W Lecture Notes - Lecture 1: Skeletal Muscle, Symmetry In Biology, Gastrovascular Cavity
Document Summary
Bio 240w test 1 study guide: hierarchy. Cells histology is the study of cells. 4 tissue types: epithelia, connective, muscle, nerve. It is the study of structures at cellular level. Simple squamous cells are found where gas exchange occurs; allows for diffusion. Simple cuboidal cells are found in glands, secretion. Simple columnar cells are found in the digestive tract, stomach & intestine, secretion and absorption. Psuedostratified columnar are found in the fallopian tubes and respiratory systems. Function: movement and secretion of the mucus: stratified. Ex. ) think of pancakes stacking up on top of each other. Types of connective tissue: embryonic, cartilage, bone, ligaments/tendons, blood. All connective tissue have cells (fibroblasts), fibers (collagen), and a matrix (environment in which cells and fibers exist) Areolar/loose found surrounding blood vessels, nerve bundles, muscles, organs, fills space between organs, and connects your skin to your underlying muscle. Regular found in tendons and ligaments.
