connects
extracellular matrix
examples - bone, blood, adipose

a thin layer of tissue that separates the epithelium from the underlying connective tissue

Basal lamina
reticular lamina

Answer 5

squamous, cuboidal, columnar

Question 6

Answer 6

transitional

Protective & impermeant

Question 7

Answer 7

Pseudostratified columnar epithelium

Question 8

what are the type of stratified epithelium found in he gut

Answer 8

secretory
squamous
cuboidal
columnar

Question 9

what do glands consist of

Answer 9

mostly secretory epithelial cells

Question 10

where do Exocrine glands secrete

Answer 10

into tubes

Question 11

where do endocrine secrete

Answer 11

into the blood

Question 12

how do glands develop

Answer 12

from columnar epithelium with stem cells

Question 13

what are the 2 types of simple exocrine gland

Answer 13

tubular - long Colum

ACINAR - light bulb shape

Question 14

what is the compound exocrine gland

Answer 14

tubuloacinar

Question 15

what are the two types of exocrine glands

what do they secrete

Answer 15

mucous galnds
secretion + water = mucus
proteoglycans (heavily glycosylated proteins)

serous glands - protein rich secretions - PANCREAS

Question 16

Myoepithelial cells

Answer 16

found in glandular epithelium as a thin layer above the basement membrane

sweat glands, mammary glands

Question 17

why are steroids only made on demand

Answer 17

as they leak out of cell

what are the two types of endocrine glands

Answer 18

proteinaceous secretion

steroid gland - adrenal cortex

Answer 21

Epithelial cells organised into nephrons

filtration of blood, partial absorption of filtrate,

Question 22

how is collagen formed

Answer 22

fibroblasts

triple stranded

Question 23

what are the 5 problems that can occur from abnormal function of epithelial cells

Answer 23
