Question 12

What is the definition of the Endothelium?

Answer 12

is a single layer of squamous endothelial cells that line the interior surface of blood vessels, and lymphatic vessels.[1] The endothelium forms an interface between circulating blood or lymph in the lumen and the rest of the vessel wall. Endothelial cells form the barrier between vessels and tissue and control the flow of substances and fluid into and out of a tissue

What does Serous mean?

Answer 13

any body fluid resembling serum

Question 14

E. layer of cells in the serous membranes are called?

Answer 14

Answer 16

Ciliated & non-ciliated

Question 17

Goblet cells is :

Answer 17

secreter of mucus accumulating in upper portion of cell bulging it out like a goblet

Question 18

Non-ciliated SC are located where?

Answer 18

gastro tract all the way through to anus

Question 19

CSC are located where?

Answer 19

Resp tract + Fallopian tubes

Question 20

SSqE=

Answer 20

Stratified Squamous E

Question 21

Keratin adds what component to cells?

Answer 21

Waterproof and resistant to bacteria and friction

Question 22

What type of E cells can contain keratin?

Answer 22

Question 23

What are 2 uncommon E cell types?

Answer 23

Strat Cuboidal + Strat column

Question 24

Strat transitional are found where?

Answer 24

bladder, ureter + urethra

Question 25

What type of celsl are attached to the basement membrane?

Answer 25

Basel

Question 26

Apical cells face where?

Answer 26

Lumen or external environment

Question 27

Gladular epithelium does what?

Answer 27

Secretes. Performed by cells under cover or lining of epithelieum

Question 28

2 types of Glands are:

Answer 28

Exocrine + Endocrine

Question 29

Endocrine glads do what?

Answer 29

secrete hormones into blood stream

Question 30

Which glandular cell is ductless

Answer 30

Endocrine

Question 31

Is the thyroid and pituitary endo or exo?

Answer 31

Endo

Question 32

What secretes substances into tubes or ducts that lead to outside body or inside tube? Can be uni or made of multi cells?

Answer 32

Exocrine gland

Question 33

Holocrine

Answer 33

Holocrine secretions are produced in the cytoplasm of the cell and released by the rupture of the plasma membrane, which destroys the cell and results in the secretion of the product into the lumen.

Question 34

Merocrine

Answer 34

A cell is classified as merocrine if the secretions of that cell are excreted via exocytosis from secretory cells into an epithelial-walled duct or ducts and then onto a bodily surface or into the lumen

Question 35

_____ also known as microscopic anatomy or microanatomy, is the branch of biology which studies the microscopic anatomy of biological tissues. ______ is the microscopic counterpart to gross anatomy, which looks at larger structures visible without a microscope. t examines the correlation between structure and function

Answer 35

Histology

Question 36

Apocrine

Answer 36

Cells which are classified as apocrine bud their secretions off through the plasma membrane producing extracellular membrane-bound vesicles. The apical portion of the secretory cell of the gland pinches off and enters the lumen.
