A&P I Tissues

A&P I - Tissues and Histology

QuestionAnswer
define "tissue" a group of cells with similar function and structure
what are the four types of tissue epithelial tissue, connective tissue, muscle tissue, and nervous tissue
list the 5 characteristics of epithelial tissue polarity, specialized contacts, basement membranes, vascular but innervated, regeneration
where is epithelial tissue found pretty much everywhere, especially anything that touches the outside (GI tract and skin)
the epithelial tissues are classified on 2 criteria - what are they? what are the names we use to describe these criteria? stratified and simple
where in the body is simple squamous ET found alveoli in lungs & glomerulus capsue (kidneys)
where in the body is simple cuboidal found tubules of the kidneys
the upper/free surface of the epithelial tissue apical surface
what is the bottom layer/surface of the epithelial tissue basal surface/lamina
what does it mean that epithelial tissue is avascular epithelial tissue does not have any blood vessel innervation of it's own
how does the blood vessel receive nutrients even though it is avascular nutrients diffuse from the basement membrane
why is it important that the epithelial tissue in the lung alveolar is simple instead of stratified the shorter the distance the faster the gasses are allowed to diffuse
why is skin made up of stratified epithelial tissue protection
name two unique epithelial tissue that are not stratified or simple pseudostratified and transitional
where is pseudostratified epithelial tissue founds respiratory system (trachea)
where is transitional epithelial tissue found bladder (urinary system)
what is an endocrine gland a gland that is ductless and releases hormones (chemicals) in to the extracellular fluid
what are exocrine glands have ducts and empty their contents (sweat/mucus) on the bodily surfaces
what is mesothelium and where is it found simple squamous epithelium found on the serous membrane
what is endothelium and where is it found simple squamous epithelium that lines the inside of a blood vessel.
name the type of epithelial tissue founds in the oral cavity moist (non-keratinized) stratified squamous epithelium
name the epithelial tissue in the trachea ciliated pseudostratified columnar epithelium
name the epithelial tissue in the capillaries simple stratified epithelium (endothelium)
name the type of epithelial tissue found in the digestive tract simple columnar epithelium (intestines), non-keratinized (moist) stratified epithelial tissue (esophagus), simple stratified (inner lining of stomach)
name the type of epithelial tissue found in the lungs alveoli simple stratified epithelium
name the type of epithelial tissue found in the kidney tubules simple cuboid epithilium
name the type of epithelial tissue in the exocrine glands stratified cuboidal
name the type of epithelial tissue in the urinary bladder transitional epithelium
what is the function of the the exocrine pancreas to buffer the stomach acid in the intestine
what is the function of the endocrine pancreas (islets of lagerhans/ pancreatic islets) release of hormones (alpha-glucagon and beta-insulin)
where would you find keratinized stratified squamous skin
where would you find non-keratinized (moist) stratified squamous buccal/oral cavity, tongue, and esophagus
what type of gland would release its secretion through exocytosis without the gland itself merocrine glands
