Flashcards in Chapter 4 Deck (38):
This tissue includes the surface of your skin; its tissue includes epithelia and glands.
Cells that produce exocrine or endocrine secretions.
A layer of filaments and fibers that attach an epithelium to the underlying connective tissue.
Large areas of opposing plasma membranes are interconnected by transmembrane proteins called these; they bind to each other and to extracellular materials.
Cell Adhesion Molecules
Specialized areas of the plasma membrane that attach a cell to another cell or to extracellular materials.
Connections between cells that permit electrical coupling.
The place where the lipid portions of the two plasma membranes are tightly bound together by interlocking membrane proteins.
Very strong areas of epithelial cels that can resist stretching and twisting; place where CAMs and proteoglycans link the opposing plasma membranes.
A gland that secretes onto the body surface or into a passageway connected to the exterior.
A passageway that delivers exocrine secessions to an epithelial surface.
A gland that secretes hormones into the blood.
One of the four primary tissue types; provides a structural framework that stabilizes the relative positions of the other tissue types; includes connective tissue proper, cartilage, bone, and blood; contains cell products, cells, and ground substance.
The extracellular fibers and ground substance of a connective tissue.
A common component of connective tissue that is a fluid.
A strong, insoluble protein fiber common in connective tissues; they are long, straight, and unbranched.
contain the same protein subunits as do collagen fibers, bur arranged differently; thinner than collagen fibers, these form a branching, interwoven framework that is tough, yet flexible.
Contain the protein elastin; are branched and wavy; after stretching, they will return to their original length.
Embryonic or fetal connective tissue.
Losse connective tissue with an open framework.
Loose connective tissue dominated by adipocytes.
Inside of this is the watery matrix is called plasma.
The fluid contents of lymphatic vessels, similar in composition to interstitial fluid.
A red blood cell; has no nucleus and contains large quantities of hemoglobin.
A white blood cell.
Small packets of cytoplasm that contain enzymes important in the clotting response; manufactured in bone marrow by megakaryocytes.
The fluid ground substance of whole blood; what remains after the cells have been removed from a sample of whole blood.
A blood vessel that carries blood away from the heart toward a peripheral capillary.
A blood vessel carrying blood from a capillary bed toward the heart.
A small blood vessel, located between an arteriole and a venule, whose thin wall permits the diffusion of gases, nutrients, and wastes between plasma and interstitial fluids.
A cartilage cell.
A connective tissue with a gelatinous matrix that contains an abundance of fibers.
A strong connective tissue containing specialized cells and a mineralized matrix of crystalline calcium phosphate and calcium carbonate; also called osseous tissue.
Lines passageways and chambers that communicate with the exterior, including those in the digestive, respiratory, reproductive, and urinary tracts; the epithelium plus the lamina propria; also called the mucosa.
A tissue characterized by the presence of cells capable of contraction; includes skeletal, cardiac, and smooth muscle tissues.
This tissue is specialized for the conduction f electrical impulses from one region of the body to another; also known as nervous tissue or nerve tissue.
One of the two basic ties of cells contained in neural tissue, not neuroglia; the longest cells in your body; cannot divide under normal circumstances.
Cells of the central nervous system and peripheral nervous system that support and protect neurons; also called glial cells.
