Epithelial

Connective

Muscle

Nerve

Functions in 4 ways

1) protects

2) absorbs

3) secretes (mucus, hormones, and enzymes)

4) excretes waste (ie urea in sweat)

Classification based on shape

flat cells

serve a protection function (ie lining mouth and skin)

Classification based on shape

shaped like cubes

function - protection and secretion

Classification based on shape

tall and retangular

function - secretion and absorption

classification of arrangement

one cell layer thick

classification of arrangement

Several layers of cells thick

classification of arrangement

Looks thick but not

cells extend from basement membrane to outer surface

classification of arrangement

several layers of closely packed stretchy cells

when stretched they look flat

when relaxed they look ragged or saw toothed

Classification Based on Function

produces mucous

Protects, absorbs nutrients, secretes enzymes and bile salts

Classification Based on Function

sweat and sebaceous glands

single unbranching ducts

Classification Based on Function

made of several branching lobules with branching ducts

ie mammary and large salivary

Classification Based on Function

ductless

secrete hormones into bloodstream

Classification Based on Function

Lines the blood and lymphatic vessels

endothelium of the heart is called the endocardium

Classification Based on Function

Serous tissue lines the great cavities

peritoneum lines the abdominal cavity

pericarium covers the heart

made of cells with lots of intercellular material

ie matrix

tough collagen or flexible elastin

can be embedded into matrix

areolar, adipose, and reticular

most widely distributed loose connective tissue

fibroblasts (make fibrils for repair)

histiocytes / macrophages (do phagocytosis)

mast cells (produce anticoagulant heparine and histamine - an inflammatory)

loose connective tissue with fat stored in cells

protects and insulates

Dense connective tissue

having regular arrangement of embedded fibers are

tensons, ligaments and aponeuroses

Dense connective tissue

having irregular arrangement of embedded fibers are

hyaline

fibrocartilage

elasic

found in the coastal cartilages 

1. attach the ribs to the sternum
2. in the septum of the nose
3. in the rings that keep the trachea and bronchi open

very strong

intervertebraldisks are made of it

easily stretched and flexible

found in ears, eppiglottis and auditory tubes

compact / dense

cancellous / spongy

teeth material

crown of teeth covered with enamel

liquid portion / plasma and blood cells

makes up lymph glands, thymus, spleen, tonsils and adenoids.

produces plasma cells / B lymphocytes producing antibodies

Reticuloendothelial System

RE system

involved in phagocytosis in connective tissue

RE cells line the spleen and bone marrow

line joints and bursae

produce synovial fluid - lubricant for joints and nourishment for cartilage

supports

provides nourishments

transports blood enzymes and hormones

connects tissues

provices movement via bones

insulates and maintains temp

protects vital organs

provides storage areas - calcium, phosphorous, fat

attaches / separates other tissues of body

smooth

striated / skeletal

cardiac

interaction of two proteins, actin and myosin

shortening of length

pulls on bones thru tendons and brings movement

long, unicellular, nonstiated

involuntary with 2 l ayers

found in digestive tract, arteries veins

long, multinucleated and striated

voluntary pull on bone = movement

only in heart

striated,  uninucleated, cylindrical in shape

responsible for pumping blood thru heart

2 layers of cells

neurons = conducting cells

neuroglia = supporting & protecting cells
