Cohn 319 Exam 1 Questions and Answers
Graded A+
What is a tissue? lump/sheet of identical cells linked together
4 types of tissue nervous, muscle, connective, epithelial
Histology definition microscopic study of tissues typically below 1,000x magnification
Cytology Histology using Electron microscopy 1,000x to 1,000,000x allowing for
intracellular ultrastructure
Integrated anatomy and physiology overview of link between structure and function
Elements Pure substances made up of pure atoms of element
Atom Smallest unit of element still retaining properties
,Four main elements carbon, hydrogen, oxygen, nitrogen
Macromolecules Lipids, carbs, proteins, and nucleic acids
Organ seen at gross anatomical level composed of two tissues may: Have overlapping
function
Bladder(urinary/excretory system) -Composed of smooth muscle
-Cells are capable of shortening producing force forcing urine out(urge to pee)
-Stretch receptors present in urethra signal brain
-Signal gets stronger and stronger
-Sphincter muscles force out
-Muscle in bladder up against connective tissue
-Bladder tissues embedded within wall(epithelium, connective, and smooth muscle tissue)
-Connective tissue(elastin fibers) allow stretching
-Bladder must be tough(connective tissue; collagen)
, -Epithelial tissue lines surfaces
-Transitional epithelium(expand and contract) serves bladder structure and function
Kidneys -Take high pressure blood and filter small molecules(ions; nitrogenous waste;
uric acid; creatinine and excess water)
-Blood/body sodium concentration regulated through urine
-Smooth muscle contraction encourages movement from kidney to bladder
-Structure allows for selective permeability
-Kidney/bladder collaborate
Every tissue type -Exists as aggregations of identical cells in sheets/lumps
-Has range of specific shapes, sizes, thickness, and intercellular connections
-has unique distribution pattern throughout the body
Histopathology definition Study of disease using microscopy(compared to normal tissue)
