Tissues - ANS-Assembled group of similar cells that share a specific function
Intercellular junction - ANS-Site of union between cells
Desmosome - ANS-Specialized junction between cells, which serves as a "spot weld;" Ex. Cells
of the outer skin layer
Epithelial tissue (Function) - ANS-Protection, secretion, absorption, excretion
Tight junctions - ANS-Closes space between cells by fusing cell membranes; Ex. Cells that line
the small intestine
Gap junctions - ANS-Form tubular channels between cells that allow exchange of gases; Ex.
Muscle cells of the heart and digestive tract
Epithelial tissue (Location) - ANS-Covers body surfaces, covers and lines internal organs,
composes glands
Connective Tissue (Function) - ANS-Bind, support, protect, fill spaces, store fat, produce blood
cells
Connective tissue (Location) - ANS-Widely distributed throughout the body
Muscle tissue (Function) - ANS-Movement
Muscle tissue (Location) - ANS-Attached to bones, in the walls of hollow internal organs, heart
Nervous tissue (Function) - ANS-Conduct impulses for coordination, regulation, integration, and
sensory reception
Nervous tissue (Location) - ANS-Brain, spinal cord, nerves
, Basement membrane - ANS-Layer of nonliving material that anchors to epithelial tissue to
underlying connective tissue
Simple squamous epithelium - ANS-Description: Single layer, flat
Function: Filtration, diffusion, osmosis, covers surface
Ex: Air sacs of lungs, walls of capillaries, lining of blood ad lymph vessels, part of the
membranes lining body cavities and covering viscera
Simple cuboidal epithelium - ANS-Description: Single layer, cube-shaped cells
Function: Protection, secretion, absorption
Ex: Surface of ovaries, linings of kidney tubules, an liings of ducts of certain glands
Simple columnar epithelium - ANS-Description: Single layer, elongated cells
Function: Protection, secretion, absorption
Ex: Linings of uterus, stomach, and intestines
Pseudostratified columnar epithelium - ANS-Description: Single layer, elongated cells
Function: Protection, secretion, movement of mucus and substances
Stratified squamous epithelium - ANS-Description: Many layers, top cells flattened
Function: Protection
Ex: Superficial portion of skin and linings of oral cavity, vagina, and anal canal
Stratified cuboidal epithelium - ANS-Description: Two or three layers, cube-shaped cells
Function: Protection
Ex: Linings of ducts of mammary glands, sweat glands, salivary glands, and pancreas
Stratified columnar epithelium - ANS-Description: Top layer of elongated cells, lower layer of
cube-shaped cells
Function: Protection, secretion
Ex: Part of the male urethra and lining of larger ducts of excretory glands
Transitional epithelium - ANS-Description: Many layers of cube-shaped and elongated cells
Function: Distensibility (the ability to stretch), protection
Ex: Inner lining of urinary bladder and linings of ureters and part of urethra
Glandular epithelium - ANS-Description: Unicellular or multicellular
Function: Secretion
Ex: Salivary glands, sweat glands, endocrine glands
Microvili - ANS-Any of the many cylindrical processes that extends from some epithelial cell
membranes, increasing membrane surface area
