Tissues

• 4 types of tissues in the human body: Epithelial, connective, muscle, nerve

Epithelial Tissue Connective Tissue Muscle Tissue Nerve Tissue Credits

Epithelial Tissue

• Almost entirely made up of cells and can regenerate by cell division

Simple Epithelial Stratified Epithelial Home

simple epithelial

• simple means 1 layer of cells

Home

stratified epithelial

• stratified means more than 1 layer

Home Stratified cubodial Stratified squamous Stratified columnar Pseudo stratified columnar transitional

pseudo stratified columnar

• pseudo stratified columnar nuclei are seen at different layers

Home

Stratified Squamous

• outer layer of skin and the esophagus and mouth.

Home

Stratified Cubodial

• Found in some sweat glands and mammary glands

Home

Stratified columnar

• found in the male urethra, pharynx and some granular ducts.

Home

Transitional

• lines the urethra, uterus and the bladder

Home

connective tissue

• Has 2 separate categories that are then divided into 5 subcategories.

• Connective tissue attaches bones to bones and muscles to bones.

Home connective tissue: bone Connective tissue: blood Connective tissue: cartilage connective tissue proper: dense irregular connective tissue proper: dense regular

connective tissue bone

• supports, protects and provides levers for muscle to become active

Home

Connective tissue: blood

• made of red and white cells in a fluid matrix.

Home

Connective tissue: cartilage

• 3 separate categories of cartilage

Home elastic cartilage hyaline cartilage fibro cartilage

hyaline cartilage

• found in trachea, the ends of long bones, nose, and larynx

Home

elastic cartilage

• supports epiglottis and ears

Home

fibro cartilage

• found in the knee joint, intervertebrael discs and the pubic symphysis

Home

connective tissue proper: dense regular

• found in ligaments, tendons, euroses

Home

connective tissue proper: dense irregular

• found in fibrous organ capsules, the dermis, and the sub mucosa of the digestive tract.

Home

Muscle

• Divided into Skeletal muscle, cardiac muscle, and smooth muscle.

• Helps the body’s skeletal system move

Home skeletal muscle smooth muscle cardiac muscle

skeletal muscle

• found in muscles that attach to bones and skin

Home

Cardiac muscle tissue

• found in the walls of the heart

Home

smooth muscle tissue

• found in the walls of hollow organs

Home

Nervous tissue

• found in brain, spinal cord, and peripheral nerves
