  • 3rd side (hint)
what is MATRIX
fibrous protiens and clear gel
what are the 3 germ cell layers
ectoderm, mesoderm, endoderm
location of ectoderm
epidermis and nervous system (outer layer)
location of mesoderm
muscle, bone, blood
(middle layer)
location of endoderm
mucous membranes of the digestive and resiratory tract, digestive glands, ect. (inner layer)
types of tissues
epithelial, connective, musclar, nervous
e c m n
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

location- epidermis, loaded with dead cells containing keratin
stratified squamous

location- mouth, esophagus, vagina, epidermis

function- protection
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
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
location- intervertebral disks and between bones

function- shock absorbers
location- skeleton

function- prtoection, support and mineral storage
location- circulatory system

function- transports gases and fights infections
location- cns

function- transmits messages
skeletal muscle
location- attached to bone

function- voluntary movement
