- did clear cells develop as epidermal cells?
- wall of bronchus
- large vein: tunica adventitia
- mammary glands
- a thickest layer. unlike in arteries. location of longitudinal bundles of smooth muscle.
- b HECKS NO. they are NOT attached to adjacent epidermal cells by desmosomes so they shrink w/ normal tissue fixation. 3 types: langerhans, melanocyte, merkel. last two are in BM
- c pre-milk secreted during last month of pregnancy and 1-3 days postpartum. protein, fat, vitamins, electrolytes, IgA, T and B leuks, LAXATIVE ACTIVITY
- d mucosa containing CPC and thin LP. sheet of smooth muscle replaces elastic sheet from trachea. this sheet of smooth muscle is incomplete in bronchi but becomes complete in bronchioles. inconspicuous submucosa, but contains some seromucous glands that drain to luminal surface. small branches of bronchial arteries found here. ill-defined, inconspicuous adventitia
- e highly modified apocrine/merocrine SWEAT glands.
5 Multiple Choice Questions
- proliferative activity slows, alveolar cells differentiate for secretory activity. Intralobular CT becomes infiltrated w/ plasma cells
- flattened cells 3-5 layers thick. contains distinct KERATOHYALIN granules that often obscure nuclei. cytokeratin filaments and LAMELLAR BODIES also in here
- alveolar cells appear more active
secretory material seen in lumina of ALVEOLI and INTRALOBULAR DUCTS. due to increased estrogen and progesterone, stimulating ductal and alveolar cells
- endothelial cells produce factor VIII (von willebrand), stored within cytoplasmic Weibel-Palade granules prior to release. may lack internal elastic membrane
- gonadal steroids, adrenal and thyroid hormones
5 True/False Questions
catagen → thin sheets of CT separating bronchopulmonary segments and through which PULMONARY VEINS travel back to hilus of lung
sebaceous glands → HOLOCRINE. fatty acids, triglycerides, waxes and cholesterol. SECRETORY: basal cells - low cuboidal which are continuous with basal cells of epidermis. entire epithelium: strat cuboidal. EXCRETORY opens onto side of hair follicle or skin surface
fibrous pericardium → dense CT covering the outside of parietal pericardium
suspensory/Cooper's ligaments → continuous
lipofuscin granules → contain von willebrand factor. in endothelial walls of arteriole tunica intima.
