Answer 1

Columnar

Question 2

3 types of epithelial cells in the fallopian tubes:

Answer 2

ciliated columnar
non-ciliated secretory columnar
intercalated columnar

Question 3

Fibre orientations of the smooth muscle of the uterine/fallopian tube?

Answer 3

Inner: circular
Outer: longitudinal

Question 4

With which ligament is the is the serosa of the uterine tube continuous?

Answer 4

broad ligament

Question 5

3 layers of the uterine wall?

Answer 5

endometrium
myometrium
perimetrium

Question 6

myometrial muscle type and orientation:

Answer 6

smooth muscle:

- ill-defined layers of longitudinal, transverse and oblique fibres

Question 7

changes occurring in the myometrium during pregnancy?

Answer 7

increased levels of oestrogen cause the myometrium to increase in size mainly via hypertrophy.
Hyperplasia also plays a limited role

Question 8

What is the function of the cervix?

Answer 8

admits spermatozoa to the genital tract during ovulation

• also links uterine cavity to vagina
• and protects the uterus from upper tract bacterial invasion

Answer 9

Endocervical canal: lined by tall columnar mucus-secreting epithelial cells
Ectocervix: Thick stratified squamous epithelial cells

Answer 10

External os

Answer 11

inner: circular
outer: longitudinal

Question 12

type pf epithelium that lines the vagina?

Answer 12

stratified squamous epithelia
