Exam 1 Cartilage and Bone TA Session Flashcards
The 4 basic types of tissue the body is composed of
- epithelial
- connective
- muscular
- nervous
Epidermus of the skin and its derivatives
Ectoderm
two subdivisions of Mesoderm
- mesothelium
2. endothelium
epithelium lining 3 serous body cavities: peritoneal, pleural, pericardial
mesothelium
epithelium lining blood and lymphatic vessels and heart chambers
Endothelium
epithelial lining and glands most of the GI tract and resop. system, liver, pancreas, urinary bladder
endoderm
5 classification criteria for glandular epithelium
- # of cells in gland
- Shape of Duct
- Shape of adenomere
- Type of Product
- Mode of Secretion
4 classification of gland according to product
- serous- watery product, contains enzymes, sweat
- mucous, viscous secretion
- mixed- produces both mucus and serous, saliva
- sebaceous- oily secretion, known as sebum
Smooth lumen, no cytoplasm lost producing secretion
merocrine
apex bulges, some cytoplasm lost producing secretion
Apocrine
entire cell is the product
holocrine
secreted product is directed toward the vasculature
endocrine
