Epithelial

Muscle

Nervous

• forms the outer skin
• lines body cavities
• covers organs
• lines organs
• makes up glands

• It always has a free surface and an attatched surface
• no blood vessels
• these cells reproduce very rapidly (the most)
• no intercellular space

• simple squamous epithelium
• simple cuboidal epithelium
• simple columnar epithelium
• ciliated columnar epithelium
• stratified squamous epithelium
• glandular epithelium

• one layer of flattened cells
• found lining air sacs in the lungs and forming capillary walls
• it is very thin so that diffusion can take place

• one layer of cubed shape cells
• found in the kidneys
• they secrete or absorb substances

• one layer of column-like cells (thicker)
• secretes digestive juices
• danger- could easily digest self

• cilia beat and move mucase out
• found in the respiratory passages and lining the female fallopian tubes

• layers of squamous epithelial cells
• these cells are produced deep and move to the surface
• found in the outer skin for protection, mouth, throat, anal canal, and vagina

• these cells manufacture and secretes substances
• 2 types: exocrine glands (ducted glands) and endocrine glands (ductless glands)

• have intercellular space and there are substances in the space
• most common cell type is a fibroblast
• have a blood supply this means it can bleed as well

• makes white and yellow protein substances
• white fibers are collagen
• yellow fibers are elastin

found in bundles

is strong and flexible but cannot stretch

1. Areolar Connective Tissue
2. Adipose Connective Tissue
3. Fibrous Connective Tissue
4. Cartilage
5. Bone
6. Blood

• cell type --> fibroblast
• cells are far apart with a jelly-like matrix
• used to underline epithelial tissue and feed them by diffusion
• if you damage your circulatory system it automatically damages the epithelial tissue
• fluids can accumulate here causing swelling or edema

• fibroblasts store lipids inside of them
• fat
• this is found around muscles, kidneys, eyeballs, abdominal membranes, heart, and joints
• uses of fat: energy storage, protection, insulation
• some people believe if you over feed an infant you increase adipose cells causing obesity possibilities

• contains a large amount of collagenous fibers closely packed 
• this gives strength and flexibility but no stretching
• this tissue binds body parts together
• tendons-connects muscle to bone
• ligaments- hold joints in place
• white of the eye- gives eye the round shape
• poor blood supply

• gristle
• the cell type is chondrocyte
• substance in the matrix is chondrin
• lacks a blood supply, heals poorly
• hyaline cartilage, elastic cartilage, fibrocartilage

• looks white and sticky
• found on the ends of bones, nose, and rings of the respiratory passages

• contains some yellow fibers
• found in the outer eats and larynx

• really tough
• many white fibers
• found in discs between vertebrae, in the knees, and between pubic bones in the pelvis

• the cell type is the osteocyte
• the substance in the matrix is calcium salts

• the cell types are red blood cells, white blood cells, and platelets
• the matrix is the plasma (or liquid part of the blood)

1. striated muscle tissue
2. smooth muscle tissue
3. cardiac muscle tissue

cells are long and thread-like and have lines going across

you can conciously shorten these cells

no striations so this contracts more slowly 

lines hollow organs (viscera)

has striations but the cells are branching to form a bag which is the heart

these cells will contract without nerves stimulation
