- 4 types of tissue- epithelial, muscle,connective, nervous tissue
- Histologist- Study of Tissues
- Pathologist-studies the diseases of cells and tissues
- Cellularity-more cells than matrix
- Tissue-group of similar cells that together carry out a specific job
- Junctions-anchor cells together so it can remain in a continuous sheet
- Basement Membrane- bottom of epithelial tissue that has glycoproteins and reticular fibers
- Microvilli- increases surface area for absorption
- Avascular- no blood vessels
- Cilia- Sweepers and cleaners
- Simple Squamous- Diffusion,filtration,slick/Lungs, heart, blood vessel, kidneys
- Simple Cuboidal- One layer, secretes, glands
- Endocrine Glands- secretes hormones directly into blood
- Exocrine Glands- products are carried by a duct to a hollow organ (digestive enzymes) or out of body (sweat)
- Simple Columnar w/ microvilli-absorption of nutrients, intestines
- Simple Columnar w/ cilia- sweeps eggs, Fallopian (uterine) tube
- Pseudostratified Columnar- secretes mucus, sweeps out debris, upper respiratory tract (trachea, bronchi, bronchioles)
- goblet cells- single cell gland that secrete mucus
- Stratified Epithelium-more than one layer, classified by top layer
- Stratified Squamous-takes friction, is a barrier, protects from fluid loss/Esophagus,skin,mouth
- Connective Tissue-Type of tissue that stratified squamous sits on top of
- Mitotic Cells-Cells in the stratified squamous tissue that regenerate (mitosis)
- Melanocytes-make and release melanin
- melanin-skin,eye, and hair pigment
- Keratin- waterproof protective top layer of skin
- Stratified Cuboidal-layered, secretes, glands
- Desquamification-Friction causing top layer of stratified squamous cells to fall off
- Transitional Epithelium-stretch to squamous shape (full) to cuboidal (empty)
- Stratified Columnar-protection, surrounds sphincter muscles, at end of stomach
