Saladin 3e - Ch 3

Human Anatomy book: Saladin 3rd edition; Ch 3 Histology Study of Tissues

QuestionAnswer
4 Types of Tissues (C-MEN): Connective Tissue, Muscle Tissue, Epithelial Tissue, Nervous Tissue,
Glands Classification - Exocrine (via ducts)mostly; - Endocrine (across membrane
Endocrine and exocrine glands secrete various products: ( HEMM ) hormones, enzymes, metabolites, and other molecules
What are the hormone producing structures of the body? Endocrine glands
modes of glandular secretion (HAM) Holocrine, Apocrine, Merocrine
Endocrine glands - location: thyroid, islet cells of the pancreas
Single layer of thin cells; nucleus flattened; cytoplasm so thin hard to see; on surface cells have angular contours and round nuclei Simple Squamous Epithelium
Lungs - Air Sacs Alveoli Simple Squamous Epithelium
Kidney - Glomerular capsules Simple Squamous Epithelium
Heart - inner lining (endothelium) Simple Squamous Epithelium
Blood Vessels - inner lining (endothelium) Simple Squamous Epithelium
Stomach - Serous membranes Simple Squamous Epithelium
Intestines and other viscera Simple Squamous Epithelium
Pleurae - surface mesothelium Simple Squamous Epithelium
Pericardium Simple Squamous Epithelium
Peritoneum Simple Squamous Epithelium
Mesentaries Simple Squamous Epithelium
Function: Allows rapid diffusion or transport of substances through membrane; secretes lubricating serous fluid Simple Squamous Epithelium
Single layer of square/round cells; in glands, often pyramidal; spherical central nuclei; often brush border microvilli or cilia Simple Cuboidal Epithelium
Brush Border - microvilli in kidney Simple Cuboidal Epithelium
Brush Border - cilia in bronchioles of lung Simple Cuboidal Epithelium
Lung - Bronchioles Simple Cuboidal Epithelium
Liver Simple Cuboidal Epithelium
Thyroid Gland Simple Cuboidal Epithelium
Mammary Gland Simple Cuboidal Epithelium
Salivary Gland Simple Cuboidal Epithelium
Kidney - Tubules Simple Cuboidal Epithelium
Function: Absorption, Secretion; production and movement of respiratory mucus" Simple Cuboidal Epithelium
Single layer of tall, narrow cells; oval shaped vertical nuclei, usually near basal half; often apical secretory vesicles visible with TEM; often brush border of microvilli or ciliated; may posses goblet cells Simple Columnar Epithelium
Stomach - inner lining Simple Columnar Epithelium
Intestines Simple Columnar Epithelium
Gallbladder Simple Columnar Epithelium
Uterus, and Uterine Tubes Simple Columnar Epithelium
Kidney - Tubules Simple Columnar Epithelium
Function (SAM): Secretion of mucus and other..., Absorption, Movement of egg and embryo in uterine tube Simple Columnar Epithelium
looks multilayered; some cells do not reach the free surface but all cells reach the basement membrane; nuclei at several levels in deeper half of epithelium; often with goblet cells; often cilliated Pseudostratified Columnar Epithelium
Function: secretes and propels mucus Pseudostratified Columnar Epithelium
Cilliated - cells with... Simple Cuboidal Epithelium, Simple Columnar Epithelium, Pseudostratified Columnar Epithelium
Microvilli - cells with... Simple Cuboidal Epithelium, Simple Columnar Epithelium,
Respiratory Tract (nasal cavity to bronchi) Pseudostratified Columnar Epithelium
Portions of male uretha Pseudostratified Columnar Epithelium
multiple cells layers, with cells becoming increasingly flat and scaly toward surface--which is covered with a layer of compact dead cells with no nuclei; basal cells may be cuboidal / columnar. Stratified Squamous Epithelium - Keratinized
Epidermis Stratified Squamous Epithelium - Keratinized
Palms and Soles Stratified Squamous Epithelium - Keratinized
Function: resist abrasion; retards water loss; resists penetration by pathogenic organisms Stratified Squamous Epithelium - Keratinized
multiple cells layers, with cells becoming increasingly flat and scaly toward surface; basal cells may be cuboidal / columnar. Stratified Squamous Epithelium - NonKeratinized
Tongue Stratified Squamous Epithelium - NonKeratinized
Esophagus Stratified Squamous Epithelium - NonKeratinized
Anal Canal Stratified Squamous Epithelium - NonKeratinized
Vagina Stratified Squamous Epithelium - NonKeratinized
Function: Function: resists penetration by pathogenic organisms Stratified Squamous Epithelium - NonKeratinized
two or more layers of cells; surface cells round or square -ish Stratified Cuboidal Epithelium
Glands - sweat gland ducts Stratified Cuboidal Epithelium
egg producing vesicles of ovaries Stratified Cuboidal Epithelium
Ducts - sperm producing ducts (seminiferous tubules) of testis Stratified Cuboidal Epithelium
Function: contributes to sweat secretion; secretes ovarian hormones; produces sperm Stratified Cuboidal Epithelium
Resembles stratified squamous epithelium, but surface cells are rounded (not flat) and often bulge above the surface; 5-6 cells thick: relaxed. 2-3: stretched. Some cells have two nuclei. Transitional Epithelium
Kidney - urinary tract Transitional Epithelium
Ureter, Uretha Transitional Epithelium
Bladder Transitional Epithelium
Allontoic duct Transitional Epithelium
External surface of umbilical cord Transitional Epithelium
Function: stretches to allow filling Transitional Epithelium
