Which side has the basement membrane?The external surface is apical (top in these pictures). The basement membrane is the bottom.46412732886364Dense Irregular00Dense IrregularIdentify each type of muscular tissue. Cardiac Muscle Smooth Muscle Skeletal MuscleShort AnswerGive one example each of an exocrine and endocrine gland.Exocrine – Sweat glands, mucus glands (trachea), digestive glands (stomach, intestines). Endocrine – Any gland that produces hormones, such as in the pancreas.Match each type of tissue to the organ it is most likely to be found in.TissueOrganSimple SquamousLMuscular layer of hollow organs like the stomach.Simple CuboidalPBrain and spinal cord.Simple ColumnarMCovers ends of bones; connects ribs to sternum.Pseudostratified CiliatedNInner lining of the urinary bladder.TransitionalDHeart muscle.Stratified SquamousQBlood cell storage, such as the lymph nodes or spleen.Skeletal MuscleOBreasts, bottom layer of skin.Smooth MuscleASeparates skin and muscle.Cardiac MuscleETendons.AreolarHExternal ear.NervousBBetween the bones (vertebrae) of the spinal column.ReticularFLining of the air sacs of the lungs.Dense RegularILining of the intestines.FibrocartilageKNasal cavity, trachea, bronchi.Elastic CartilageJFound in any voluntary muscle, like the deltoid.Hyaline CartilageCLining the tubules of many glands and the kidneys.AdiposeGOuter layers of the skin.What might happen if we had simple squamous instead of stratified squamous epithelium on our skin?The skin would be much thinner. It would break easily on contact, and would not be very protective.What would happen if we had stratified squamous instead of simple squamous in the air sacs of our lungs?Oxygen and carbon dioxide would not be able to diffuse into our blood as easily.Simple cuboidal cells, unlike squamous, are found in areas where a lot of secretion occur, such as glands. Why do the cells need to be larger?Being able to produce and secrete requires endoplasmic reticulum and golgi, which are large organelles that take up a lot of space.Simple columnar cells are also found in areas high in absorption and secretion, such as the digestive tract. What is the advantage of having larger cells in these areas?The digestive tract is exposed to acids, digestive enzymes, and food. A thicker, more protective layer of cells ensures these materials stay inside the GI pare tight junctions, desmosomes, and gap junctions. First, give an example of a tissue where each is found. Second, explain their function within that tissue.Tight junctions – Simple columnar epithelium. Provides a waterproof seal between cells.Desmosomes – Stratified squamous epithelium. Anchor to neighboring cells.Gap junctions – Cardiac muscle. Allows material and signals to travel between cells quickly.Body organs are made of combinations of different types of tissue. This is a slide taken from the trachea, which transports air down towards the lungs. There are two types of epithelium present, and one type of connective tissue present. Label them.22021806096000Pseudostratified Ciliated ColumnarSimple cuboidal Hyaline Cartilage ................
