Name the 4 types of tissue
Epithelial, connective, muscle & nervous
Briefly describe epithelial tissue
- covers the bodys surfaces
- covers and lines organs
- makes up glands
Briefly describe connective tissue
- widely distributed throughout the body
- fills internal spaces
- binds, supports + protects bodys structures
Briefly describe muscle tissue
-specialized for contraction
-includes skeletal, cardiac and smooth which lines walls of hollow organs
skeletal muscle attaches to bone and is used for movement of the body
Briefly describe nervous tissue
- carries information from one part of the body to another via electrical impulses
- found in the brain,spinal cord and nerves
Name the 9 types of epithelial tissue
simple squamous epithelium simple cuboidal epithelium simple columnar epithelium stratified squamous epithelium stratified cuboidal epithelium stratified columnar epithelium pseudostratified columnar epithelium transitional epithelium glandular epithelium
Function and example of simple squamous epithelium
- lines alveoli
- forms capillary walls
- lines blood & lymph vessels
- covers body cavity membranes
- diffusion, filtration, osmosis
examples: alveoli, blood & lymph vessels
Function and example of simple cuboidal epithelium
- covers ovaries
- lines kidney tubules
- glandular ducts
examples: ovary surfaces, kidneys, ducts of glands
Function and example of simple columnar epithelium
- found in female reproductive tubes, uterus, most digestive tract organs
- absorption, protection, secretion
example:respiratory passages
Function and example of stratified squamous epithelium
- forms epidermis
- lines the mouth, esophagus, vagina and anus
- protection
example: outer layer of skin
Function and example of stratified cuboidal epithelium
- lines mammary gland ducts
- lines sweat gland ducts
- lines salivary glands
- lines pancreas
- lines developing ovaries
- protection
example:glands
Function and example of stratified columnar epithelium
- lines male urethra
- lines ductus deferens
- lines pharynx
- protection
example:male urethra & pharynx
Function and example of pseudostratified columnar epithelium
- lines respiratory passages
- secretion
- protection
- movement of mucous
example: respiratory passages
Function and example of transitional epithelium
- lines urinary bladder
- lines ureters
- prevents urinary tract contents diffusing back into body
- distensibility
- protection
example: urinary tract
Function and example of glandular epithelium
- usually found in exocrine or endocrine glands
- secretion
example:glands
Explain fluid connective tissue
Blood and lymph are fluid connective tissues that contain distinctive collections of cells in a fluid matrix.
They transport many materials between interior body cells + other cells that exchange substances with the external environment maintaining a stable internal environment.
Name the 3 types of muscle tissue and their characteristics
skeletal muscle
-voluntary muscles controlled by conscious effort
smooth muscle
-composed of elongated spindle-shaped cells in muscles not under voluntary control
cardiac muscle
- myocardial/myocardium
- thick contractile middle layer of the heart wall
Discuss the basic structure of neural tissue
- neurons are the basic structure of neural tissue
- respond to environmental changes by transmitting impulses along axons (cellular processes) to other neurons, to muscles r to glands.
- neurons co-ordinate,integrate + regulate a wide variety of functions in the body
