Body Tissue By Angeli
-
Epithelium Tissues
Simple
-
Simple Columnar
-
Function
-
-
Lines stomach, intestines, and parts of respiratory tract
-
-
-
A single layer of tall, narrow cells
Simple Squamous
-
-
A single layer of very thin, irregularly shape/scale-like cells.
because of the structure, substances can readily pass through its cells -> transport is the special function
Pseudostratified
Single layer, but some cells are shorter than others
-
-
Stratified
Stratified Squamous
-
-
Multiple layers of cells, but cells at the outermost edge are flat
-
Transitional
-
-
Multiple layers of epithelial cells which can contract and expand in order to adapt to the degree of distension needed
Muscular Tissues
Cardiac Muscle
-
-
Branching, interconnected cylinders with faint striations. Cells only have one nucleus.
-
Smooth Muscle
Location
Walls of tubular viscera of digestive, respiratory, and genitourinary tracts.
-
-
-
-
-
Threadlike cells with single nuclei and no striations. They also attached to other smooth muscle cells.
Skeletal Muscle
-
Function
Maintainance of posture, movement of bones
-
-
Cells are long, striated, threadlike, and have multiple nuclei; they also attach to connective tissues. Muscle can be controlled voluntarily by body movements.
Connective Tissues
-
Adipose Tissue
-
-
Cells contain large fat vesicle. Turned from areolar tissues to adipose tissues when areolar begins to store lipid/fat
-
Cartilage
Location
Part of nasal septum, area covering articular surfaces of bones, larynx, rings in trachea and bronchi
-
-
-
Hard but somewhat flexible gel matrix with embedded chondrocytes (cartilage cells in tiny spaces throughout matrix)
-
Bone
-
-
Hard, calcified matrix arranged in osteons. Composed of bone cells in lacunae (cavities), hard matrix of calcium salts, large numbers of collagen fibers
-
