1

Fxn and Location of Simple Squamous Epithelium

Diffusion! located: alveoli, bowman's capsule, endothelium

2

Fxn (3) and Location of Simple Cuboidal Epithelium (3)

Absorption, Secretion, minimal protection. Location: small ducts of exocrine glands, thyroid follicles, kidney tubules

3

Function (1) and location (1) of Simple columnar Epithelium

Function: absorption
location: GI tract

4

Function (3) and location (2) of pseudostratified epithelium

Fxn: absorption, secretion, transport
Location: vas deferens/epididymis, bronchial tree

5

function and location of stratified squamous epithelium

Protection

Skin (keratinized), vagina, oral cavity, esophagus

6

function (2) and location (2) of stratified cuboidal epithelium AND stratified columnar epithelium

Protection and conduit

large ducts exocrine glands, anorectal jxn

7

function and location of transitional epithelium

distension

bladder

8

holocrine secretions

A mode of exocrine secretion in which the cell dies and releases its contents

9

apocrine secretions

a mode of exocrine secretion in which a cell releases a vesicle with its contents

10

merocrine secretions

a mode of exocrine secretion in which a cell exocytoses its contents (most common)

11

what type of exocrine gland is a eccrine sweat gland? secretion type?

multicellular, simple coiled tubular (serous secretions)

12

what type of exocrine gland is the intestinal gland? secretion?

multicellular, simple tubular, mucus secretions

13

what type of exocrine gland is the pancreatic gland? secretion type?

mutlicelllar, compound acinar, serous secretions

14

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

15

what is an apical pulse?

listen to the pulse with stethescope

16

what is a peripheral pulse

palpate or feel the pulse

17

what is eosin? what does it reveal?

an acidic dye that binds to positively charged molecules (cytoplasm, collagen, muscle fibers)

18

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

19

epidermis: composition, originates?

keratinized stratified squamous epithelium. originates from ectoderm

20

dermis: composition, originates?

composed of connective tissue, mesoderm

21

what are the layers of the dermis?

superficial: papillary layer, loose areolar connective tissue

deep: reticular layer, dense irregular connective tissue

22

what is connective tissue?

cells in an ECM

23

what is the ECM

ground substance and protein fibers

24

what are the types of connective tissue?

Specialized: Bone, cartilage, blood

Connective tissue proper:
dense: regular, irregular
loose: reticular, areolar, adipose

25

how do you calculate the incidence rate?

Incidence/sum of disease-FREE person time

26

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)

27

what is the relationship between prevalence and incidence?

P=(incidence)(duration)

28

which AA is a precursor for heme?

Gly

29

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

30

what is cachexi? symptoms? treatment?

a hyper-catabolic state in which protein and AA (Gln) are degraded (negative nitrogen balance). Symptoms: weight loss, seen in cancer renal disease and burns.
Treat: anabolic steroids
