Identification? Description? |
Simple Squamous Epithelium -Single Layer of flattened cells with disc-shaped central nuclei and sparse cytoplasm |
|
|
histology |
the study of tissues |
|
Identification? Function? Location? |
Simple Squamous Epithelium -Allows Materials to pass by diffusion and filtration in sites where protection is not important -Air sacs of lungs; lining of heart, blood vessels, lining of ventral body cavity |
|
Identification? Description? Function? Location? |
Transitional Epithelium -Resembles both stratified squamous and stratified cuboidal -stretches readily, permits stored urine to distend urinary organ -lines the ureters, bladder, and part of the urethra |
|
Identification? Description? Function? Location? |
Simple Cuboidal Epithelium -Single layer of cube-like cells with large, spherical central nuclei -secretion and absorption -kidney tubules, ducts, and secretory portions of small glands; ovary surface |
|
Identification? Description? Function? Location? |
Pseudostratified columnar epithelium -single layer of cells of differing heights, some not reaching the free surface -secrete substances, particularly mucus; propulsion of mucus by clilary action -ciliated variety lines the trachea, most of the upper respiratory tract |
|
Identification? Description? Function? Location? |
Connective Tissue: Aredar Tissue -gel-like matrix with all three fiber types: cells, fibroblasts, macrophages, mast cells, and some white blood cells -wraps and cushions organs; its macrophages phagocytize bacteria -widely distributed under epithelia of body; form lamina propria of muccous membranes |
|
Identification? Description? Function? Location? |
Connective tissue adipose -matrix as in areolar, but very sparse; closely packed adipocytes, or fat cells, have nucleus pushed to the side of large fat droplet -provides reserve food fuel; insulates against heat loss; supports and protects organs -under skin in subcutaneous tissue; around kidneys and eyeballs; within abdomen;in breasts |
|
Identification? Description? Function? Location? |
Connective tissue: Elastic -dense regular connective tissue containing a high proportion of elastic fibers -allows tissue to recoil after stretching: maintains pulsatile flow of blood through arteries; aids passive recoil of lungs following inspiration -walls of large arteries; within certain ligaments associated with the vertebral column; within the walls of the bronchial tubes |
|
Identification? Description? Function? Location? |
Hyaline Cartilage -amorphous but firm matrix; collagen fibers form an imperceptible network; chonblasts produce the matrix and when matrix and when mature lie in lacunae -supports and reinforces serves as resilient cushion; resists compressive stress -forms most of the embryonic skeleton;covers the ends of long bones in joint cavities forms costal cartilages of the rivs; cartliages of the nose, treachea, and larynx |
|
Identification? Description? Function? Location? |
elastic cartilage -similar to hyaline cartilage but more elastic fibers in matrix -maintains the shape of a structure while allowing great flexibility -supports the external ear epiglottis |
|
Identification? Description? Function? Location? |
Smooth Tissues -spindle-shaped cells with central nuclei; no striations; cells arranged closely to form sheets -propels substances or objects along internal passageways; involuntary control -mostly in the walls of hollow organs |
|
Identification? Description? Function? Location? |
cardiac muscles -branching,straited,generally uninucleate cells that interdigitate at specialized junctions -as it contracts, it propels blood into the circulation; involuntary control -the walls of the heart
|
|
Identification? Description? Function? Location? |
skeletal muscle -long, cylindrical, mulitnucleate cells -voluntary movement; locomotion; manipulation of the enviroment; facial expresssion; voluntary control -in skeletal muscles attached to bones or occasionally to skin |
