Editor's Notes
- Slide #43 – Endocardium, subendocardium, myocardiumPurkinje fibers in subendocardium
- Slide #44 – large muscular arteryEndothelium, internal elastic lamina, tunica media (elastic fibers & smooth muscle), external elastic lamina, & tunica adventitia (vasovasorum)
- Central Vein Portal Triad – hepatic portal vein, hepatic artery, bile duct
- Islets of Langerhans:Alpha cell – secrete glucagon increase blood glucoseBeta cell – secrete insulin decrease blood glucoseDelta cell – secrete somatostatin inhibit release of other islet cell hormones
- Proximal convoluted tubule – columnar epithelium with tall microvilliDistal convoluted tubule – cuboidal epithelium
- Collecting duct – simple cuboidal epithelium
- Umbrella Cells – flatten cells
- Plentiful of oocytes!
- Corpus albicans scar tissue
- **Autonomic sympathetic
- Cervis – mostly connective tissue (compared to uterus body)
- Oviduct – muscosa, muscularis, serosa
- PEG CELLS – nourishes sperm cellsCILIATED CELLS – movement of sperm (?)
- Leydig cells = interstitial cells (steriod-secreting endocrine cells)
- What type of epithelium lines the surface of the cord? Pseudostratified columnar epithelium
- **corpora amylacea – more plentiful as you age
