HSII Ch. 3 Tissues

epithelial tissue definition
- covers body & lines body cavities
- cells packed closely together with little matrix
- classified by shape
types of epithelial tissue
- squamous
- cuboidal
- columnar
- transitional (can be stretched)
types of epithelial tissue layers
- simple= single
- stratified= layers
connective tissue definition
- most abundant and widely distributed tissue
- many diff. types, appearances, & functions
- relatively few cells in intracellular matrix
types of connective tissue
- areolar
- adipose (fat)
- fibrous
- bone
- cartilage
- blood
areolar tissue

glue holds organs together
adipose (fat)

lipid storage
fibrous
- strong fibers
- ex: tendon
bone
- matrix is calcified
- support & protection
cartilage

chondrocyte is a cell type
blood
- fluid matrix
- transportation
types of muscle tissue
- skeletal
- rough
- smooth
- cardiac
skeletal tissue
- attaches to bones
- also called straited or voluntary
- control is voluntary
- straiations appearant when viewed under microscope
smooth tissue
- also called nonstriated voluntary (visceral) or involuntary
- no cross striations
- foud in blood vessels and other tube-shaped organs
cardiac tissue
- also called straited involuntary
- composes heart wall
- usu. can't control contractions
types of nervous tissue
- nerons
- glia
neurons
- conducting cells
- rapid comm. btwn body structures and control body functions
neuron structure
- cell body
- one axon carries nerve impulse away from cell body
- 1+ carry nerve impulses toward cell body
glia
- (neuroglia)
- supportive & connects cells
