Specialized cells that together perform a common function are called
The four basic types of tissue in the body are
Epithelial, Connective, Muscle, and Neural
Which of these embryonic germ layers gives rise to muscle, bone and blood vessels
Characteristics of epithelial tissue
Covers free body surfaces, lacks blood vessels, composes various glands, anchored to connective tissue by a basement membrane
Tissue that functions in support and protection of body organs, stores energy, and provides immunity is
Connective Tissue
The type of tissue that contains actin and myosin filaments, and accounts for movement is
Muscular Tissue
The tissue that enables us to be aware of the external environment and to react to it
Nervous Tissue
The type of cellular junction that forms an impermeable barrier, where plasma membranes join is called
Tight Junctions
The type of cellular junction that forms when a channel is formed between two adjacent plasma membranes is
Gap Junction
The purpose of gap junctions is
allow substances to pass directly from one cell to the next
The type of cellular junction that forms when adjacent plasma membranes have filaments that firmly attach at button-like thickenings are
Adhesion Junctions
Does Epithelial tissue have a high mitotic capacity
Epithelial tissue cells have an apical surface at the top and are attached to a basement membrane at the bottom
The glycoprotein membrane that joins an epithelium to underlying connective tissue
basement membrane
Epithelial tissue is named according to
Cell shape and layer arrangement
Lines most of the digestive tract
Simple columnar
Lines the esophagus
Sratified Squamous
Lines much of the respiratory tract
Pseudostratified ciliated columnar
Forms the walls of the air sacs of the lungs
Simple Squamous
Found in urinary tract organs
Simple Cuboidal
Endothelium and mesothelium
Simple Squamous
Which of the following epithelia most easily permits diffusion
Simple Squamous
Which of the following epithelia function is absorption and secretion
Columnar and Cuboidal epithelium
Goblet cells are found in which of the following tissues
Columnar Epithelium
Epithelium composed of two or more layers of cells with an apical layer of flattened cells and only the deepest layer in contact with the basement membrane
Stratified epithelium
Stratified epithelium is usually found in areas of the body where the principal activity is
Stratified squamous epithelium cells are found in the
In parts of the body such as the urinary bladder, where considerable expansion occurs, one can expect to find which type of tissue
Transitional Epithelium
Epithelium that appears to have several layers of cells but does not, is classified as
Pseudostratified epithelium
The gland type that secretes products such as milk, saliva, bile or sweat through a duct is
Exocrine gland
The type of gland that secrete their product directly into the bloodstream are
Endocrine Gland
Glands that accumulate secretions and release them only when the individual secretory cells rupture and die are called
If the lining of an organ produces and releases mucus, which of the following cells would likely be found in the tissue lining the organ
Goblet Cell
Mucous secretions that coat the passageways of the digestive and respiratory tracts result from
Merocrine Secretion
The type of exocrine gland that forms its secretory product and simply releases it from the cell by exocytosis is
Merocrine gland
A gland has a duct that branches repeatedly, and the ducts end inn saclike structures , this is
compound acinar
Mesenchymal Cells
Form embryonic connective tissue, give rise to all adult connective tissues, in adults produce new connective tissue cells in response to injury.
All the following cells can be found in connective tissue
Fibroblasts, macrophages, plasma celss. mast cells
Matrix is a characteristic of which type of tissue
The ground substance of the connective tissue matrix is produced by connective tissue cells
Three basic types of fibers in connective tissue is
Collagen, reticular, elastic
The fibers in the matrix of connective tissue are made of
The fibers in dense connective tissue are produced by
Connective tissue fibers that are arranged in bundles and lend strength and flexibility to a tissue are collagen fibers
Connective tissue fibers that can be stretched considerably without breaking
Elastic Fibers
The slippery viscous substance that binds cells together and lubricates joints is
Hyaluronic acid
The type of connective tissue with a liquid matrix called plasma is
where can you find elastic connective tissue
wall of arteries
A tissue with a large number of collagen fibers organized parallel to each other would most likely be found in
Dense irregular connective tissue can be found in
Dermis of skin
Extremely delicate fibers that make up the framework for organs such as the liver, spleen, and lymph nodes
Reticular fibers
What is the main function of fibrous connective tissue
Characteristics that apply to cartilage
cells are located in lacunae, proteoglycans in ground substance, perichondrium on surface
Cartilage provides
support and flexibility, lacks blood vessels and is composed of chondrocytes
The type of cartilage that is found at the ends of the long bones, nose, ribs, and respiratory passages
The type of cartilage that can withstand great pressure and tension, and is found between the vertebra
The very elastic type of cartilage that is found in the epiglottis and external ear
The cells of mature cartilage is
The type of cartilage growth characterized by adding new layers of cartilage to the surface is
Appositional growth
Why does damaged cartilage heal slowly
Cartilage is avascular, so materials needed for repair must diffuse from surrounding tissue
Osseous tissue is classified as
Connective Tissue
The basic unit of compact bone is
The membrane lining body cavities that open to the exterior is
Mucous membrane
Linings of the digestive, respiratory, excretory, and reproductive passages are composed of
Mucous membranes
This membrane produces a watery fluid for lubrication
The primary function of serous membranes in the body is to
Minimize friction between opposing surfaces
