Week 3 - Exam 1

Question 1

epithelial cells function

Answer 1

covering/bordering body/organ, protects from environment, connected to underlying tissue via basal membrane

Question 2

4 types of epithelial cells

Answer 2

squamous, stratified, transitional, and glandular

Question 3

where can you find simple squamous epithelial cells and why

Answer 3

lung, kidney, glands; 1 layer allows for easier diffusion

Question 4

where can you find stratified epithelial cells

Answer 4

skin and rumen (stomach of cow)

Question 5

where can you find transitional epithelial cells

Answer 5

urogenital tract (only)

Question 6

structure of a glandular epithelial cell

Answer 6

duct, cells, secretory units, basement membrane

Question 7

types of structures of exocrine glandular epithelial cells

Answer 7

tubular, branched, coiled, alveolar

Question 8

3 major classes of glandular epithelial cells

Answer 8

exocrine, endocrine, and paracrine

Question 9

3 types of exocrine glandular epithelial cells

Answer 9

merocrione, apocrine, holocrine

Question 10

function of a glandular epithelial cells

Answer 10

produce secretions (proteins=enzymes, lipids, carbs)

Question 11

3 characteristics of a fiber

Answer 11

collagen, glycosaminoglycans, hyaluronic acid

Question 12

function of adipose tissue

Answer 12

energy storage, temperature insulation

Question 13

where can you find supportive tissue

Answer 13

cartilage, bone

Question 14

3 types of cartilage

Answer 14

elastic, hyaline, fibrous

Question 15

where can you find elastic cartilage and function

Answer 15

ear, larynx, trachea; provide structural support

Question 16

where can you find hyaline cartilage and function

Answer 16

joint surface; provides joint movement, cushions movement, no blood vessels

Question 17

where can you find fibrous cartilage

Answer 17

intervertebral discs, meniscus in knee and jaw

Question 18

merocrione function

Answer 18

fuses, then dumps contents (like the bubbles we saw with Golgi Apparatus)

Question 19

apocrine function

Answer 19

don’t dump contents

Question 20

holocrine function

Answer 20

cell wall ruptures, dies, but high turn over rate (found in digestive tract)

Question 21

endocrine function & example

Answer 21

product goes inside (example: adrenal gland: hormones into blood)

Question 22

paracrine function

Answer 22

release components and influence cell itself again

Question 23

collagen arches

Answer 23

help with springiness

Question 24

no vascular supply usually means

Answer 24

poor healing quality
