Definition
| Closely packed cells. Arranged in sheets: Single layer and Multiple layers. Adheres firmly to the connective tissue via the basement membrane. Nerve supply, but no blood supply. High mitotic rate-- cells subjected to a great deal of wear and tear. |

|
Term
| Epithelial vs. Connective Tissue |
|
Definition
| Epithelial tissue w/many cells tightly packed together and little to no extracellular matrix. Connective tissue w/a few scattered cells surrounded by large amounts of extracellular matrix. |
|
|
Term
| Characteristics of Connective Tissue |
|
Definition
| Lots of matrix. Few cells. Don't occur on free surfaces. Highly vascularized and has a nerve supply. Except tendon and cartilage. |
|
|
Term
| Composition of Connective Tissue |
|
Definition
| Mostly fibroblasts. Fibroblasts secrete matrix. Ground substance: Large molecules such as polysaccharides and proteins. Fibers: Consist of collagen. Elastic. Reticular. |
|
|
Term
| Function of Connective Tissue |
|
Definition
| Binds and supports. Separates structures. Stores reserve energy. |
|
|
Term
| Classification of Connective Tissue |
|
Definition
| Mature: Loose, Dense, Cartilage, Bone, and Blood |

|
Definition
| Function: Provides motion, Maintains posture, Generates heat. Ex. Tendon |

|
Term
| Classification of Muscle Tissue |
|
Definition
| Skeletal Muscle: Attached to bone. Striated-- light and dark bands. Long and cylindrical. Voluntary controlled. Skeletal muscles move or stabilize the position of the skeleton; guard entrances and exits to the digestive, respiratory, and urinary tracts; generate heat; and protect internal organs. |

Definition
| Heart Muscles, Striated, Involuntary, Intercalated discs - strengthen the tissue and provide a route for quick conduction. Moves blood and maintains blood pressure. |
|
|
Term
|
Definition
| Found in walls of hallow structures: Blood vessels, stomach, airways, and bladder. Nonstraited. Involuntary. Smooth muscle moves food, urine, and reproductive tract secretions; controls diameter of respiratory passageways and regulates diameter of blood vessels. |

|
Definition
| Neurons - structural and functional units of the nervous system: dendrites, nucleus, cell body, axon, myelin sheath, axon ending. |
|
|
Term
|
Definition
| Neuroglia: Protects and supports neurons. Often the site of tumors in the nervous system. |
