Types of Tissue
Terms in this set (28)
Tissue composed of layers of closely spaced cells that cover organ surfaces, form glands, and serve for protection, secretion, and absorption.
Tissue with more matrix than cell volume, often specialized to support, bind together, and protect organs.
Tissue containing excitable cells specialized for rapid transmission of coded information to other cells.
Tissue composed of elongated, excitable cells specialized for contraction.
Simple squamous epithelium
Single layer of thin, flattened cells that allow rapid diffusion or transport of substances through membrane; secretes lubricating serous fluid; Found lining the air sacs of the lungs, kidneys tubules; and some other viscera.
Simple cuboidal epithelium
Single layer or square or round cells that function in absorption and secretion; production of protective mucous coat; Found in the liver, thyroid, mammary, salivary and other glands.
Simple columnar epithelium
Single layer of tall, narrow cells with oval or sausage shaped nuclei that function in absorption, secretion of mucous and other products; Found in the iner lining of the stomach, intestines, gallbladder, uterus and some kidney tubules.
Pseudostratified columnar epithelium
Appears multi-layered though some cellsdo not reach free surface though all cells reach the basement membrane; funcions to secrete and propel mucous. Found in respiratory tract from nasal cavity to bronchi.
Keratinized stratified squamous
Multiple cell layers with cells becoming increasingly flat and scaly toward the surface with the top layer consisting of dead cells; found epidermis especially in places with heavy wear (soles/palms).
Non-keratiized stratified squamous
Multiple cell layers with cells becoming increasingly flat and scaly toward the surface WITHOUT the top layer consisting of dead cells; found in the mucosa of the vagina, tongue, esophagus oral mucosa.
Similar to stratified squamous but surface cells are rounded and can adjust to stretching; found in the bladder and other parts of the urinary tract.
Type of loose connective tissue with loose arrangement of collagenous and elastic fibers; loosely binds epithelia to deeper tissues.
Type of loose connective tissue that is dominated by adipocytes; used for energy storage, thermal insulation, protective cushion.
Dense regular connective tissue
Type of dense connective tissue with densely packed, parallel, often wavy collagen fibers; tendon and ligaments.
Dense irregular connective tissue
Type of dense connective tissue; densely packed collagen fibers running in random direction; durable, hard to tear; capsules around viscera such as liver kidney and spleen.
Type of cartilage that eases joint movement; found between the ribs and helps shape many parts of the throat.
Tpe of cartilage with elastic fibers that form a weblike mesh to provide flexible, elastic support.
Type of cartilage with parallel collagen fibers and can be found as intervertebral discs.
Long, cylindrical, unbranched cells with striations and multiple nuclei per cell; functions in body movement, posture etc and is under voluntary control.
Tissue made of short cells with notched or slightly branched ends found in the heart.
Short fusiform cells overlapping each other, nonstriated with only one nucleus per cell; functions in swallowing and movement of food through the digestive tract.
loose (areolar) connective tissue
type of connective tissue with small amounts of cells, matrix, and fibers; found around blood vessels
loose reticular connective tissue
lymphoid organs (lymph nodes, bone marrow, and spleen)
bone connective tissue
mineralized and forms the skeleton
blood connective tissue
fluid extracellular matrix used to transport substances throughout the body.
Nerves functioning outside your brain and spinal cord.
Nerves that carry information from the central nervous system to the muscles of the body.
motor nerve ending
a nerve ending in contact with a specialized effector organ such as a motor end plate in muscle
