Unit 2 - Histology
| Histology Term | Definition |
|---|---|
| Simple Squamous Epithelium | Appearance: Single layer of flat cells Function: absorption |
| Stratified Squamous Epithelium | Appearance: Multiple layers of flat cells Function: absorption |
| Cuboidal Epithelium | Appearance: Cube-shaped cells Function: absorption |
| Columnar Epithelium | Appearance: cells that are longer than wide Function: absorption |
| Psuedostratified Epithelium | Appearance: Cells appear to be layered due to irregularly placed nuclei Function: protection, secretion, movement |
| Transitional Epithelium | Appearance: cells are different shapes/sizes Function: allows for stretching |
| Adipose Connective Tissue | Stores fat, provides insulation |
| Dense Regular Connective Tissue | Parallel bundles of collagen fiber found in tendons and ligaments |
| Dense Irregular Connective Tissue | Bundles of collagen fiber run in different directions |
| Reticular Connective Tissue | Lymphatic tissue that produces white blood cells |
| Hyaline Cartilage | Cartilage that contains collagen; makes up tip of nose, ends of long bone and ribs and rings in trachea |
| Elastic Cartilage | Cartilage that contains elastic and collagen fibers; found in ears |
| Fibrocartilage | Matrix contains strong collagenous fibers to absorb shock and friction; found in knee and vertebrae joints |
| Compact Bone | Dense bone found on outer portion of long bones |
| Spongy bone | Bony bars and plates are irregularly spaced; found in ends of long bone and makes blood cells |
| Blood | Liquid connective tissue made up of erythrocytes, plasma, leukocytes, and platelets. |
| Skeletal Muscle | Striated columns of voluntary contractile tissue found in skeletal muscles |
| Smooth Muscle | Spindle-shaped cells of involuntary contractile tissue found in digestive organs and blood vessels |
| Cardiac Muscle | Striated, branched involuntary contractile tissue found in the heart |
| Nervous Tissue | Groups of neurons that send impulses to communicate |
| Epithelial Tissue | covers body surfaces and organs, lines body cavities |
| Connective Tissue | binds and supports body parts |
| Histology | the branch of anatomy that studies the structure of animal tissue on a microscopic level |
| Tissue | A group of cells that all perform the same specific function |
