|
|
|
function of epithelial tissue
|
secretion, digestion, absorbtion, protection, filtration, lubrication, excretion
|
|
|
|
characteristics of epithelial tissue
|
single or muti layer, apical surface, has basement mem, covers body surface and outer surfaces of organs, lines inner surfaces of body cavity and organs, doesn't have blood supply, has nerve supply, high capasity for mitosis, derived from all 3 germ cell layers
|
|
|
|
classification of epithelial tissue
|
simple and stratified
|
|
|
|
simple epithelial tissue
|
all cells touch basement membrane and only have one layer- 4 types S, Squamous, S. Cuboildal, S. Columnar, Pseudostratified ciliated columnar
|
|
|
|
stratified epithelial tissue
|
st. squamous- keratinized and non-keratinized, transitional
|
|
|
|
simple columnar
|
location- linig os stomach, small and large intestines
function- secretion and absorption |
|
|
|
simple squamous
|
location- lining of aveoli and blood vessels
function- perfect for diffusion |
|
|
|
pseudostratified ciliated columnar
|
location- lining of trachea
function- secretion and movement of mucus by cilia |
|
|
|
simple cuboidal
|
location- kidney tubules
function- secretion and absorption |
|
|
|
stratified squamous
keratinized |
location- epidermis, loaded with dead cells containing keratin
|
|
|
|
stratified squamous
non-keratinized |
location- mouth, esophagus, vagina, epidermis
function- protection |
|
|
|
transtional
|
location- lining of bladder
function- permits distention |
|
|
|
functions of connective tissue
|
binding of organs, support, physical protection, immune, movement, storage, heat production, transport
|
|
|
|
characteristics of connective tissue
|
most abundant of the tissues, 3 basic elements are cells, fibers, and ground subs, highly vascular and has nerve supply
|
|
|
|
componets of connective tissue
|
cells- fibroblasts, wbc, plasma cells, fat cells, chondrocytes/blasts, osteocyets/blasts
fibers- collagen, reticular, elastic ground substance- gags |
|
|
|
types of connective tissue
|
loose areolar, reticular, adipose, dense regular, dense irregular, hyaline cartilage, elatic cartilage, fibrocartilage, bone and blood
|
|
|
|
loose areolar
|
location- subcutaneous layer, body organs
function- strength, elasticity and support |
|
|
|
reticular
|
location- lymph nodes, spleen, red bone marrow
function- makes the structural framework |
|
|
|
adipose tissue
|
also known as fat,
location- subcutaneous layer, capsule around kidneys function- insulation, protection, support, energy reserve |
|
|
|
dense regular
|
location- tendons and ligaments
function- tendons attach muscle to bone and ligaments hold bones together |
|
|
|
dense irregular
|
location- dermis, periosteum, perichondrium
function- provide strength where force is exerted in different directions |
|
|
|
hyaline cartilage
|
location- ends of bones, nose, respiratory tubes
function- support and protection |
|
|
|
elastic cartilage
|
location -ears
function- flexible support |
|
|
|
fibrocartilage
|
location- intervertebral disks and between bones
function- shock absorbers |
|
|
|

|
location- skeleton
function- prtoection, support and mineral storage |
|
|
|

function- transmits messages |
|
|
|
skeletal muscle
|
location- attached to bone
function- voluntary movement |
|
