TISSUES Name the 4 basic tissue types in the human body. Epithelium, connective, muscle, nervous Which of the tissues of the body are vascular? Which are avascular? Vascular – muscle, connective (bone & connective tissue proper) Avascular- epithelium, nervous, connective (cartilage & blood) What are the special characteristics of epithelial tissue? Has polarity; a basal and apical surface, minimum cellular material, all epithelium is bound to a basement membrane Name the classifications of epithelial tissue based on 1) layering 2) shape 3) other modifications 1) simple, stratified, pseudostratified 2) squamous, cuboidal, columnar, transitional 3) Cilia, microvilli, stereocilia, goblet cells For each classification above, what are the associated functions? Where in the body would you find simple squamous epithelium? Stratified squamous? Air sacs of lungs, cardiac cavity Stratified squamous – skin, nostrils, lips, mouth, esophagus Where in the body would you find simple cuboidal epithelium? Simple columnar? Simple cuboidal – secretion, absorption; in ducts of many glands, kidney Simple columnar – secretion/absorption; in stomach, intestines Where in the body would you find transitional epithelium? What makes it different from other epithelia? Bladder, ureters It can stretch and then return back to its original shape Differentiate between cuboidal, columnar, and squamous epithelia. How would you distinguish them on a slide? Cuboidal – cube like, nucleus is proportional to cell Columnar – nucleus is smaller than cell Squamous – flat, one nuclei Name the 4 main types of connective tissue. Blood, bone, cartilage, connective tissue proper What are the characteristics of connective tissue? Transport, support, storage defense; holds body together; transports salts, gases, nutrients, wastes

Mostly extracellular and vascular What are the different subtypes of CT proper? What are the functions of each? loose irregular (areolar) connective tissue - dense irregular - dense regular - What kind of fibers would you find in areolar CT? In reticular CT? In adipose CT? Areolar – collagen, elastic, reticulin Reticular CT – reticulin, Adipose CT – none? Where in the body would you find dense regular CT? Dense irregular CT? Elastic CT? Dense regular – ligaments and tendons Dense irregular – dermis of skin Elastic – bladder, aorta? What distinguishes cartilage from other kinds of connective tissue? Mature cells (chondrocytes and osteocytes) located in distinct cavities called lacunae Extracellular ground substance is different from other kinds of connective tissue (organic material) What are the 3 types of cartilage? What distinguishes them from each other? Hyaline – moderate amount of collagen; looks like bubbles Elastic – collagen and elastin fibers; flat, thin, long, 1 nucleus sitting against edges of bones Fibrocartilage – lots of collagen Where would you find hyaline cartilage in the body? Elastic cartilage? Fribrocartilage?
