chp 5 Flashcards
Groups of similar cells with a common function.
Tissue
Major types of tissues in the body.
- Epithelial Tissue
- Connective Tissue
- Muscle Tissue
- Nervous Tissue
The study of the structure and function of tissues.
Histology
Covers body surface, cover and line internal organs, compose glands.
Epithelial Tissue
Widely distributed throughout the body.
Connective Tissue
Attached to bones, in the walls of hollow internal organs, heart.
Muscle Tissue
Found in the brain, spinal cord, nerves.
Nervous Tissue
Lacks blood vessels, cells readily divide, cells are tightly packed.
Epithelial Tissue
Mostly have good blood supply, cells are farther apart than epithelial cells, with extracellular matrix in between.
Connective Tissue
Able to contract in response to specific stimuli.
Muscle Tissue
Cells communicate with each other and other body parts.
Nervous Tissue
Has a free surface on the outside and basement membrane on the inside.
Epithelial Tissue
Function of Tissue: protection, secretion, absorption, excretion, filtration, diffusion, and sensory reception.
Epithelial Tissue
Thin, flattened cells.
Squamous
Cube shaped cell.
Cuboidal
Elongated/ Rectangular cells.
Columnar
Single layer of cells.
Simple
Two or more layers of cells.
Stratified
Appears layered but is not.
Pseudostratified
Single layer of thin, flat cells.
Simple Squamous
Found: Lining air sacs & capillaries. (LUNG)
Lines blood & lymphatic vessels.
Simple Squamous
Lines kidney tubules, thyroid follicles, ducts of some glands, covers ovaries.
Simple cuboidal
Single layer of cube shaped.
Simple cuboidal
Single layer of elongated cells.
Simple columnar
Nuclei usually at the same level, near basement membrane.
Simple columnar
Lines uterus, stomach, intestines.
Simple columnar
Lines respiratory passageways.
Pseudostratified columnar
Many cell layers; thick, protective layer.
Outermost cells are flat, deeper cells are cuboidal.
Stratified squamous
Stratified squamous found in the outer layer of skin.
Keratinized
Stratified squamous lining the oral cavity, vagina, anal canal.
Nonkeratinized
2-3 layers of cube shaped cells
Stratified cuboidal
Lines ducts of mammary, sweat glands, salivary glands, and pancreas.
Stratified cuboidal
Top layer of elongated cells, cube shaped cells in deeper layers.
Stratified columnar
Lines part of male urethra, ducts of exocrine glands.
Stratified columnar
Changes shape with increased, tension. Stretches.
Transitional
Forms the inner lining barrier of the urinary bladder, ureters and part of urethra.
