Cells |
Function according to the protein they make I.e. Red blood cells make hemoglobin so they can transport oxygen. Pancreatic make insulin so all cells can absorb glucose Muscle cells make actin/myosin so they can contract |

-Found in small intestines, lines nasal cavities GI track, mucosa (mucous membrane) |
|
|
Psuedostratified Ciliated Columnar Epithelium |
-Found in trachea - Appear in different height and gives impression of layers - Function is absortion and secretion |
|
|
Stratified Squamous |
-Found in esophagus and areas of abuse or friction |
|
|
Stratified Columnar and Stratified Cuboidal |
Rare but found in ducts of large glands |
|
|
Transitional Epithelium |
- Stretchy and layered -Found in the urinary system - modified squamous |
|
|
Connective Tissue |
Cells with fibers scattered in a matrix |
|
|
Areolor |
|
|
Areolor tissue |
-found under skin and between muscles -binds organs together
|
|
|
Adipose |
|
|
Adipose |
-Found beneath skin and in breast tissue, kidneys, and heart -Provide insulation, padding, energy storage |
|
|
Bone |
|
|
Bone tissue |
- founds in skeletons - provide support, protection, levers for muscles to act upon movement, - central canal- for vessels, blood, and nerves |
|
|
Blood |
|
|
Blood tissue |
-Found in blood vessels - transports oxygen, nutrients, CO2, waste. Provides body with immunity (white blood cells) |
|
|
Cartilage |
Chondrocyte (cartilage cell) |
|
|
Hyaline Cartilage |
|
|
Hyaline Cartilage |
-Glassy, smooth matrix -Found in embryonic skeleton, ends of long bones, where ribs attach to breast bone (caustil cartilage), nasal septum, trachea (rings). larynx - Function is support, reduces friction (joints) |
|
|
Elastic |
|
|
Elastic cartilage |
-Made up of elastic fibers - found in ears and epiglottis -Provides support and flexibility |
|
|
Fibro Cartilage |
|
|
Fibrocartilage |
-lots of thick collagen fibers - Found in discs between vertebrae, Mencius, and between pubic bones - Function is shock absortion
|
|
|
Dense Fibrous |
- compacted collagen fiber -Found in ligament, tendons, covering muscles, lower layers of dermis - Supports and binds joints, keeps muscles in place |
|
|
Reticular |
|
|
Reticular |
-network of interwoven reticular fibers associated w/ reticular cells - found in spleen, lymphnodes, bone marrow, soft internal framework for other cells |
|
|
Muscle Tissue |
specialized to contract or shorten to produce movement |
|
|
Skeletal |
|
|
Skeletal |
-Voluntary -Attached to bones - Function is to move body parts |
|
|
Smooth muscle |
|
|
Smooth muscle |
- Involuntary - Found in internal organs and blood vessels - Moves substances through tubes |
|
|
Cardiac |
|
|
Cardiac |
-involuntary -Heart - Pumps blood - intercalated discs |
|
|
Nerve Tissue |
|
|
Nerve Tissue |
- made up of neurons - 3 parts of neuron - Carries impulses that permit communication between body parts
|
|
|
Cell Body |
contains nucleus |
|
|
Dendrite |
carries toward cell body |
|
|
Axon |
carry messages away from the cell |
|
|
Sensory Neuron |
-relays info to the cord -gives message to interneuron |
|
|
Interneuron |
-Between sensory & motor neuron - Completely inside cord |
|
|
Motor Neuron |
-Relay message from interneuronn - Goes to effector (I.e. muscle, gland) |
|
|
Regeneration |
same kind of cells dividing to repair minor wombs |
|
|
Fibrosis |
involves repair by dense connective tissue by the formation of scar tissue |
|
|
1st step of Fibrosis |
Permeability of capillaries will increase -Fluid will exit blood to tissue (swelling) and will allow clotting |
|
|
2nd step of Fibrosis |
Clot will form -stop bleeding - wall of womb preventing bacteria from entering |
|
|
3rd step of Fibrosis |
Clot dries and scab forms |
|
|
4th step of fibrosis |
Granulation tissue forms - nearby capillaries grow into injury sire and form this delicate pink tissue |
|
|
5th step of fibrosis |
GT phagocytes destroy the scab |
|
|
6th step of fibrosis |
GT fibroblasts are going to make scar tissue to bridge the gap |
|
|
7th step of fibrosis |
Simultaneously epithelial cells under scab divide to produce layer over GT |
|
|
8th step of fibrosis |
Scab falls off |
|
|
9th step of fibrosis |
May see thin white line or scar, usually will go away with time |
|
|
Cancer |
uncontrollable cell division |
|
|
neoplasms |
tumor |
|
|
Benign tumors |
-non cancerous -walled off from surrounding tissue |
|
|
Malignant tumor |
-Cancerous - Permeating into surrounding tissue - biopsy of lymphnodes, if cancer is found then it may be spread |
