4 Types of Tissue |
Epithelial, Connective, Muscle, Nervous |
|
|
Epithelial |
This type of tissue - forms coverings, linings, glands, little or no cellular matrix, lateral surface attaches to neighbors, AVASCULAR w/out blood vessels. |
|
|
Glands |
Specialized secretory structure composed of epithelial cells |
|
|
Unicellular |
goblet cells that secrete mucus |
|
|
Multicellular |
endocrine glands that secrete products directly into blood |
|
|
Exocrine glands |
secrete products into ducts |
|
|
Merocrine |
only the product is secreted (no loss of cellular material) |
|
|
Apocrine |
Apex (tip) of cell pinches off with product |
|
|
Holocrine |
whole cell is shed (sebaceous gland) |
|
|
Fibroblast |
Product protein fibers |
|
|
Adipocytes |
store fat |
|
|
Macrophages |
are mobile white blood cells that ingest foreign material |
|
|
Mast Cells |
release inflammatory chemicals |
|
|
Collagen fibers |
straight rope like strong but flexible |
|
|
Elastic Fibers |
branched, wavy, can stretch and recoil |
|
|
Reticular Fibers |
form interwoven frameworks |
|
|
GAGs |
polysaccharides that hold water |

|
|
Cartilage |
is chondrocytes in lacunae |
|
|
Bone |
osteocytes in lacunae |
|
|
Hyaline Cartilage |
glassy matrix, very few visible fibers, support joint movement |
|
|
Fibrocartilage |
parallel collagen fibers in thick bundles, compression resistance, shock absorption, intervertebral joints. |
|
|
Elastic Cartilage |
web like mesh of elastic fibers, flexibility, external ear |
|
|
Axon |
carries outgoing signals |
|
|
Dendrites |
receive incoming signals |
|
|
Neuroglia |
supporting cells |
|
|
Mucous Membranes |
line passageways that open to the outside of the body |
|
|
Serous Membranes |
line trunk cavities (not open to the outside) |
|
|
Cutaneous Membrane |
the skin (type of membrane) |
|
|
Synovial Membrane |
lines freely moveable joints |
