Cards

Term
Types of Body Tissue
Definition
  • epithelial
  • muscular
  • nervous
  • connective
  • those surrounding an organ
Term
fixation
Definition
tissue is immersed in a  preservative solution to maintain the tissue's existing structure
Term
embedding
Definition
water is removewd with alcohol and the tissue is impregnated with paraffin wax
Term

sectioning

 

Definition
the tissue is cut into extremely thin slices by an instrument called a microtome. When the section runs the length of the tissue, it is called a longitudinal section; when the section runs across the tissue, it is called a cross section.
Term
staining
Definition
the tissue is immersed in dyes that stain different structures. The most common dyes are hematoxylin and eosin stains (H & E). They give a differential blue and red color to the basic and acidic structures within the tissue
Term
squamous
Definition
scale-like, many-sided cell shape
Term
cuboidal
Definition
cube-shaped cells
Term
columnar
Definition
colum  shaped cell
Term
simple
Definition
a type of layer that only has one layer of cells
Term
stratified
Definition
type of layer where there are multiple layers of cells packed on top of each other
Term
pseudostratified
Definition
a type of layer that appear to be layered but actually aren't
Term
microvilli/cilia
Definition
cellular extensions
Term
keratin
Definition
a type of protein that makes the outer layer of epidermis tough, protective, and able to repel water
