Anatomy Unit 3: Tissues

Group of similar cells working together to preform a function

Connective, epithelial, muscle, nervous

Covers all body surfaces, main glandular tissue, has cells packed tightly together

Basement membrane

Protection, secretion, absorbtion, excretion, sensory perception

Single layer

Multiple layers

Flat

Square

Columns (rectangles)

Diffusion and filtration in lungs, capillaries

secretion/absorption in the kidneys

secretion/absorption within intestines, can have mircrovilli

protects underlying tissues, located in the mouth and esophagus

Appear stratified, can have cilia, aids movement, located in the trachea, nasal passages

Stretchable, blocks diffusion, bladder

Secretes substances, endocrine and exocrine glands

Ducts, sweat, saliva

secretes into blood, hormones

Multilayer cube, production of sweat/mammary gland ducts

Most abundant tissue, binds structures together, composed of scattered cells in matrix

Binds underlying organs to skin and each other – thin, delicate, membranes

Tendons (muscle to bone) and ligaments (bones to bones), strongest tissue but least flexible

Protective cushion, isulation, stores energy

Type of dense connective tissue

Covers ends of joints, nasal septum, trachea, is slippery and smooth, reduces friction and pads

External ear and larynx

Tough, shock-absorbing, between vertebras

Hyaline, elastic, fibrocartilage

Loose connective areoler tissue, adipose tissue, dense fiberous connective tissue, cartilage, bone tissue (osseous), blood tissue

Cardiac, skeletal, smooth

Neurons, neuroglia

Conducts messages to the brain

Attatches to bones for movement

Contracts the heart

Found in blood vessels and instestines
