this tissue type provides physical protecton, controls permeability and,produces specialized secretions.
this suface faces exterior or internal space, faces the lumen. Has either microvilli or cilia
this surface refers to both the area that attaches to underlying tissues and the neighboring cells
arranged like floor tiles and are thin and flat.
cells are as tall as they are wide and are shaped like cubes or hexagons. Have cilia or microvilli at the apical surface. function for absorption or secretion.
cells are much taller than they are wide, like columns. Have cilia or microvilli at the apical surface and are specialized for absorption or secretion.
a single layer of cells
several layers of cells
intercellular attachment that attaches the deepest epithelial cells to the basal lamina. Basal lamina is also called the
this tight junction forms a barrier that prevents the passage of water and solutes between cells
this junction locks together the terminal webs of neighboring cells, strengthening the apical region and preventing distortion and leakage at the occluding junctions
this junction permits chemical communication to coordinate activities of adjacent cells. Formed by interlocking junctional proteins called connexons.
this junction provides firm attachment between neighboring cells by interlocking their cytoskeletons
simple squamous epithelium
these epithelium cells are found in protected regions where absorpton or diffusion takes place. these include alveoli of the lungs, along kidney passages, blood vessels and lymphatic
stratified squamous epithelium
these epithelium cells are found where protection is needed. Forms the surface of the skin and lines the mouth, throat, esophagus, rectum, anus and vagina
these epithelium cells are found lining the kidney tubules and lining exocrine glands and ducts.
this unusual stratified epithelium stretches and recoils and is located in the urinary bladder urethra and urine-collecting chambers of kidneys
these epithelium cells are found in the stomach,intestine uterine tubes and kidney ducts. most will have microvilli on the apical surface to increase absorption
pseudostrafified columnar epithelium
these epithelium cells appear stratified, but each one is attached to the basal membrane. cells typically possess cilia and are located in the nasal cavities, trachea and larger airways of the lungs
name for a collection of epithelial cells that produce secretions. There are two types endocrine and exocrine.
one type of secretion and is the most common type. Product is released through exocytosis
this type of secretion loses it apical surface.and cytoplasm with secretion. an example is in the mammary glands.
with this secretion the entire cell bursts, releasing secretion and killing cell
most abundant tissue type in the body. it has a number of functions including binding tissues together, supports and strenthens tissue, protects and insulates internal organs and energy reserves and immune responses. highly vascular
a material that is located between the cells. consists of protein fibers and ground substance.
this substance is found between the cell and fibers. functions to support and bind cells, store water, and allows exhange between blood and cells.
a strong fiber that is flexible, resists pulling and is the largest of the three.
a fiber the can stretch and recoil
a fiber that provide support and strength
most common loose connective tissue. packing material of the body. has all connective tissue proper cell types
loose connective tissue found deep to skin in various areas of the body. most cells are (adipocytes)
loose connective tissue. found in liver, kidney, spleen, lymph nodes, and bone marrow. provides support and resists distortion
dense connective tissue
this tissue type has most of of its volume occupied by extracelllular fibers. three types regular, irregular, and elastic
dense regular connective tissue
this dense tissue is found in tendons, ligaments, and organ cords. has parallel collagen fibers.
dense irregular connective tissue
this dense tissue is found covering visceral organs; in superficial layers of bones, cartilages, and peripheral nerves. no consistent pattern of fiber arrangement.
this connective tissue is more elastic fiber than collagen. is springy and resilient. found between vertebrae, and in walls of large blood vessels.
fluid connective tissue
this tissue type has a fluid matrix with many suspended proteins. normally without fibers.two types blood and lymph
this tissue type has a firm matrix containing poysaccharide derivatives. Cells (chondrocytes) only cell in cartilage matrix occupy small chambers (lacunae[lacus, lake). three types hyaline, elastic and fibrous.
this cartilage is found between ribs and sternum, covering bones in mobile joints, cerain areas fo respiratory system. it is stiff but flexible support and reduces friction
this cartilage supports extermal ear and other smaller internal structures. it has increased flexibility
this cartilage is found within knee joints,between pubic bones of the pelvis and in intervertebral discs. it resists compression, prevents bone-to-bone contact and limits relative movement.
this tissue type has a bony matrix with a small volume of ground substance 2/3 of matrix is calcium salts(provides strength). many collagen fibers (provide flexibility).
this bone type lines the internal cavity of long bones
this bone type lines the outer layer of long bones
line or cover body sufaces. consist of epithelium supported by connective tissue and there are four types. mucous, serous, cutaneous and synovial.
this membrane lines organs that communicate to exterior. must be kept moist to facilitate movement, absorption. or secretion. lubricated by mucus or bodily fluids. supported by areolar connective tissue.
this membrane has three subdivisions that are in the ventral cavity. pleura, peritoneum, and preicardium
this membrane covers the surface of the body
this membrane lines joint cavities of all freely movable joints. line bursae and tendon sheaths. no epithelial cells just special cell that secrete slippery synovial fluid
this muscle type has cells are long, cylindrical, banded (striated), and have multiple nclei (multinucleate). functions move skeleton generate heat and protect internal organs
this mucsle type has cellsthat are short, banched, and have a single nucleus. interconnected with special junctions(intercalated discs)
this muscle type is found throughout the body. cells are short, spindle-shaped, nonstriated, and have a single nucleus.
this tissue is specialized for conduction of electrical impulses with two basic types of cells. neurons and neuroglia or glial cells
these cells transfer information around the body and perform information processing.vary in size and shape
