Epithelial tissues (3)

• Anything that lines something

• Composed entirely of cells

• Forms sheets held together by junctions and desmosomes

Apical

Top, or free part of epithalial

Basal

Bottom of epithelail

Epithelial regeneration

very fast

Connective tissue

• Most diverse and abundant

• cartilage

• bone

• blood

• connective tissue proper

Where does connective tissue come from?

mesenchyme

Functions of connective tissue (4)

• binding and support

• protection

• insulation

• transportation

Collagen

• A connective tissue fiber

• tough

• tensile strength

• skin taughtness

Elastic

• Connective tissue fiber

• long, thin that allow for stretch

• stretch marks

Recticular

• branched collagenous fibers

• form delicate networks

fibroblasts

cells in connective tissue proper

Chondroblasts

cells in cartilage

Osteoblasts

Cells in bones

hemapoieitc stem cells

cells in blood

Adipose

fat, insulates, stores food, supports and protects

Dense regular

tendons, ligaments, parallel collagen fibers

Hyaline cartilage

• supports, reinforces, cushions resists compression

• firm and ridgid

• nose, trachea

Elastic cartilidge

• elastic, structure, flexible

• ear

fibrocartalidge 

• strength and absorbs shock

• vertebral disks, knee

Bone

hard, supports, protects, vascular

Blood

transports gas, nutrients, waste

Nervous tissues

transmit electrical signals from receptors

Skeletal muscles

• voluntary movements

• attached to bones (occasionally skin)

• long, cylindrical cells, obvious striped

Cardiac muscles

• in heart

• involuntary

• propels blood

• branched, stripes

Smooth muscles

• walls of hollow organs

• propels materials

• spindle cells, NO stripes
