hypertonic
higher solute outside, higher water inside, water moves out and cell shrinks
isotonic
equal solute, equal water, no net movement,
hypotonic
higher solute inside, higher water outside, water moves IN, cell swells
simple squamous
consists of a single layer of flat cells with a centrally located, flattened nucleus.
simple cuboidal epithelium
short and have a spherical, central nucleus.
simple columnar epithelium
spherical nuclei generally located near the base of the cell.
psuedostratified ciliated columnar epithelium
looks as if it has many cell layers but actually has only one layer of cells
Stratified squamous keratinized epithelium
consists of epithelial cells called keratinocytes that produce the protein keratin. flaky looking cells
Stratified squamous nonkeratinized epithelium
contains no keratin and is located in places subject to lesser degrees of mechanical stress, such as the oral cavity, the pharynx, the anus, and the vagina
Transitional epithelium
the apical or surface cells are dome-shaped, but when the tissue is stretched, they flatten and are squamous in appearance.
loose areolar connective tissue
gives it a “loose” appearance on a slide
reticular connective tissue
consists of many reticular fibers produced by cells
adipose tissue
consists mostly of huge cells called adipocytes with collagen fibers in the ECM. Each adipocyte contains a large lipid droplet that occupies most of its cytoplasm.
dense regular collagenous tissue
collagen fibers arranged in parallel bundles with little ground substance and few cells.
dense irregular collagenous tissue
bundles of collagen fibers. Collagen bundles are arranged in an irregular, haphazard fashion without a consistent pattern.
dense elastic connective tissue
elastic fibers arranged in parallel bundles.
hyaline cartilage
chondrocytes scattered in ground substance with few visible protein fibers. smooth, glassy appearance
