Fxn and Location of Simple Squamous Epithelium
Diffusion! located: alveoli, bowman's capsule, endothelium
Fxn (3) and Location of Simple Cuboidal Epithelium (3)
Absorption, Secretion, minimal protection. Location: small ducts of exocrine glands, thyroid follicles, kidney tubules
Function (1) and location (1) of Simple columnar Epithelium
location: GI tract
Function (3) and location (2) of pseudostratified epithelium
Fxn: absorption, secretion, transport
Location: vas deferens/epididymis, bronchial tree
function and location of stratified squamous epithelium
Skin (keratinized), vagina, oral cavity, esophagus
function (2) and location (2) of stratified cuboidal epithelium AND stratified columnar epithelium
Protection and conduit
large ducts exocrine glands, anorectal jxn
function and location of transitional epithelium
A mode of exocrine secretion in which the cell dies and releases its contents
a mode of exocrine secretion in which a cell releases a vesicle with its contents
a mode of exocrine secretion in which a cell exocytoses its contents (most common)
what type of exocrine gland is a eccrine sweat gland? secretion type?
multicellular, simple coiled tubular (serous secretions)
what type of exocrine gland is the intestinal gland? secretion?
multicellular, simple tubular, mucus secretions
what type of exocrine gland is the pancreatic gland? secretion type?
mutlicelllar, compound acinar, serous secretions
what four steps should you follow prior to taking vital signs?
wash your hands, introduce yourself and verify patient, tell the patient about the procedure and ask if they have any questions, ask if the patient has done anything (meds, exercise, pain) that will alter vitals
what is an apical pulse?
listen to the pulse with stethescope
what is a peripheral pulse
palpate or feel the pulse
what is eosin? what does it reveal?
an acidic dye that binds to positively charged molecules (cytoplasm, collagen, muscle fibers)
what is hemtoxyln dye? what does it reveal?
a basic dye that binds to negatively charged molecules. DNA/RNA. Hematoxylin and Eosin (H&E) are commonly used together
epidermis: composition, originates?
keratinized stratified squamous epithelium. originates from ectoderm
dermis: composition, originates?
composed of connective tissue, mesoderm
what are the layers of the dermis?
superficial: papillary layer, loose areolar connective tissue
deep: reticular layer, dense irregular connective tissue
what is connective tissue?
cells in an ECM
what is the ECM
ground substance and protein fibers
what are the types of connective tissue?
Specialized: Bone, cartilage, blood
Connective tissue proper:
dense: regular, irregular
loose: reticular, areolar, adipose
how do you calculate the incidence rate?
Incidence/sum of disease-FREE person time
what is disease free person time? how can it be measured?
the amount of time (in years) that each subject was without a disease. You can either add up the total years (most exact), you can average the number of people and multiply by years (500,000 people *1 yr), or you can average the number of years and multiply by people (100 people*2.5 yrs)
what is the relationship between prevalence and incidence?
which AA is a precursor for heme?
how do you calculate nitrogen balance? what are the three nitrogen balance terms?
Nitrogen balance= Nitrogen consumed-nitrogen excreted
positive nitrogen balance, negative nitrogen balance, nitrogen equilibrium
