Essay Question Samples for EXAM #2 (Remember: protein synthesis is also on this exam, but questions will not be in the essay format.) Describe the differences between exocrine and endocrine glandular epithelium. Endocrine glands- ductless, secretes hormones into the blood Exocrine glands- duct to surfaces, secrete their products onto the body surfaces(skin) or into body cavities (mucous, sweat, oil, and salivary glands) What are the 4 types of cells found in connective tissue and of what type of connective tissue are they a part? What is keratin, and where is it located? Keratin is formed by Keratohyaline granules and is found in the Stratum Granulosum layers of the skin. What is the function of cilia found associated with pseudostratified columnar epithelium? The cilia helps keep substances moving through the esphogus, GI tract while they are being digested. Describe the composition of one of the following types of connective tissue - areolar, dense regular or fibrocartilage. (You need to include cell type, fiber type and ground substance). Of the type you choose, what is its function and identify a possible location. (Note that in this sample question only 3 types of CT were used. In the exam, ANY 3 could be substituted in this type of essay question). Areolar: Cells: Fibroblasts, macrophages Fibers: Loose arrangement of all 3 Ground substance: High fluid content Function: Packing material between other tissues Locations: Under skin (+ adipose), around blood vessels, nerves, mucous membranes Dense regular: Cells: Fibroblasts Fibers: Collagen bundles (parallel) Ground substance: Scant Functions: Tension exerted in one direction Locations: Tendons, ligaments, aponeuroses Fibrocartilage: Thick collagen fibers - strong support, withstand compression Locations: Intervertebral discs Menicus (knee) Pubic symphysis (pelvis) What is the function of cell adhesion proteins and proteoglycans? Describe the composition, location, function and characteristics of a mucous or serous membrane. Mucous Membrane Epithelium various types CT areolar loose (lamina propria) Location - Lines body cavities open to the exterior (Ex: digestive, urinary, reproductive, respiratory tracts) Serous Membrane Epithelium Simple squamous CT areolar loose Location: Lines body cavities NOT open to the exterior (Ex: pericardium - covers heart; pleura covers lungs, peritoneum lines abdominopelvic cavity + organs in it) What is the function of melanocytes? Procduce pigment melanin and protects against UV radiation What changes occur in the epidermis as you move from the basal layer to the apical layer? Cells accumulate more keratin Cell membrane thickens Cells change shape Cell death Name 2 skin appendages and their functions. Nails- scratch, pick up objects Hair- Sensation, guard scalp against physical trauma, heat loss, and sunlight How does skin play a role in body temperature regulation? (2 mechanisms should be addressed). Blood flow adjustments Dilation increase heat loss (cooling) Constriction decrease heat loss (warming) Describe 2 changes that occur in skin and bone with age. SKIN Fibroblasts Decrease production of collagen + elastic fibers Wrinkles: Collagen fewer, stiffen, break apart, tangle Elastic lose elasticity, thicken into clumps Glands atrophy dry skin Melanocytes decrease Color changes, age spots BONES Lose bone mass, become more brittle Demineralization lose calcium Estrogen Osteoporosis: resorption > deposition Lose protein Decrease collagen fibers Lose tensile strength Easier to fracture Explain how osteocytes that are entrapped in the osteoid get nutrients and oxygen. Name 3 differences between compact and spongy bone. Compact- few spaces, Spongy-no osteons, Describe the hormonal control of bone remodeling. Negative Feedback mechanisms, <a href="/keyword/parathyroid-hormone/" >parathyroid hormone</a> , calcitonin *<a href="/keyword/parathyroid-hormone/" >parathyroid hormone</a> Stimulus decrease in blood Ca2+ levels PTH released from parathyroid glands PTH stmulates osteoclasts Result: Resorb bone matrix Ca2+ released into the blood *Calcitonin Stimulus increase in blood Ca2+ levels Calcitonin released from the thyroid gland Calcitonin stimulates osteoblasts, inhibits osteoclasts Result: Calcium salt deposition in bone matrix Decrease in blood calcium
