Tissue Level of Org Flashcards
connective tissue
type of tissue that serves to hold in place, connect, and integrate the body’s organs and systems
connective tissue membrane
connective tissue that encapsulates organs and lines movable joints
cutaneous membrane
skin; epithelial tissue made up of a stratified squamous epithelial cells that cover the outside of the body
ectoderm
outermost embryonic germ layer from which the epidermis and the nervous tissue derive
endoderm
innermost embryonic germ layer from which most of the digestive system and lower respiratory system derive
epithelial membrane
epithelium attached to a layer of connective tissue
epithelial tissue
type of tissue that serves primarily as a covering or lining of body parts, protecting the body; it also functions in absorption, transport, and secretion
histology
microscopic study of tissue architecture, organization, and function
lamina propria
areolar connective tissue underlying a mucous membrane
mesoderm
middle embryonic germ layer from which connective tissue, muscle tissue, and some epithelial tissue derive
mucous membrane
tissue membrane that is covered by protective mucous and lines tissue exposed to the outside environment
muscle tissue
type of tissue that is capable of contracting and generating tension in response to stimulation; produces movement
nervous tissue
type of tissue that is capable of sending and receiving impulses through electrochemical signals
serous membrane
type of tissue membrane that lines body cavities and lubricates them with serous fluid
synovial membrane
connective tissue membrane that lines the cavities of freely movable joints, producing synovial fluid for lubrication
tissue
group of cells that are similar in form and perform related functions
tissue membrane
thin layer or sheet of cells that covers the outside of the body, organs, and internal cavities
totipotent
embryonic cells that have the ability to differentiate into any type of cell and organ in the body
gland
structure made up of one or more cells modified to synthesize and secrete chemical substances
anchoring junction
mechanically attaches adjacent cells to each other or to the basement membrane
apical
that part of a cell or tissue which, in general, faces an open space
apocrine secretion
release of a substance along with the apical portion of the cell
basal lamina
thin extracellular layer that lies underneath epithelial cells and separates them from other tissues
basement membrane
in epithelial tissue, a thin layer of fibrous material that anchors the epithelial tissue to the underlying connective tissue; made up of the basal lamina and reticular lamina
cell junction
point of cell-to-cell contact that connects one cell to another in a tissue
endocrine gland
groups of cells that release chemical signals into the intercellular fluid to be picked up and transported to their target organs by blood
endothelium
tissue that lines vessels of the lymphatic and cardiovascular system, made up of a simple squamous epithelium
exocrine gland
group of epithelial cells that secrete substances through ducts that open to the skin or to internal body surfaces that lead to the exterior of the body
gap junction
allows cytoplasmic communications to occur between cells
goblet cell
unicellular gland found in columnar epithelium that secretes mucous
holocrine secretion
release of a substance caused by the rupture of a gland cell, which becomes part of the secretion
merocrine secretion
release of a substance from a gland via exocytosis
mesothelium
simple squamous epithelial tissue which covers the major body cavities and is the epithelial portion of serous membranes
mucous gland
group of cells that secrete mucous, a thick, slippery substance that keeps tissues moist and acts as a lubricant
pseudostratified columnar epithelium
tissue that consists of a single layer of irregularly shaped and sized cells that give the appearance of multiple layers; found in ducts of certain glands and the upper respiratory tract
reticular lamina
matrix containing collagen and elastin secreted by connective tissue; a component of the basement membrane
