1
Q

what are the uterine tubes also known as?

A

fallopian tubes

oviducts / salpinx

2
Q

what are uterine tubes?

A

muscular ‘J-shaped’ tubes, found in the female reproductive tract

3
Q

where do the uterine tubes lie?

A

in the upper border of the broad ligament

4
Q

where do the uterine tubes extend?

A

laterally from the uterus

5
Q

where do uterine tubes open into?

A

the abdominal cavity, near the ovaries

6
Q

what is the main function of the uterine tubes?

A

assist in the transfer and transport of the ovum from the ovary, to the uterus

7
Q

what are the ultrastructures of the uterine tube which assist the movement of female gamete?

A

inner mucosa

smooth muscle layer

8
Q

how does the inner mucosa assist with the movement of female gamete?

A

inner mucosa is lined with ciliated columnar epithelial cells and peg cells

9
Q

what are peg cells within the inner mucosa of fallopian tubes?

A

non-ciliated secretory cells

10
Q

function of the ciliated columnar epithelial of inner mucosa?

A

They waft the ovum towards the uterus and supply it with nutrients

11
Q

how does the SM layer assist the movement of female gamete?

A

contracts to assist with transportation of the ova and sperm

12
Q

what are the SM of the fallopian tubes sensitive to? what does this mean?

A

Muscle is sensitive to sex steroids, and thus peristalsis is greatest when oestrogen levels are high

13
Q

what are the different anatomical parts of the fallopian tube? (lateral to medial)

A
4 parts:
fimbriae
infundibulum
ampulla
isthmus
14
Q

what is the fimbriae of the fallopian tube? (function)

A

Finger-like, ciliated projections which capture the ovum from the surface of the ovary

15
Q

what is the infundibulum of the fallopian tube?

A

Funnel-shaped opening near the ovary to which fimbriae are attached

16
Q

what is the ampulla of the fallopian tube?

A

Widest section of the uterine tubes

17
Q

what is the isthmus of the fallopian tube?

A

Narrow section of the uterine tubes connecting the ampulla to the uterine cavity

18
Q

where does fertilisation normally occur?

A

within the ampulla of the fallopian tube

19
Q

arterial supply of the fallopian tube?

A

via the uterine and ovarian arteries

mainly ovarian artery - uterine near the isthmus

20
Q

venous drainage of the fallopian tube?

A

via the uterine and ovarian veins

21
Q

lymphatic drainage of the fallopian tube?

A

via the iliac, sacral and aortic lymph nodes

22
Q

where does the fallopian tubes receive innervation from?

A

both sympathetic and parasympathetic innervation via nerve fibres from the ovarian and uterine (pelvic) plexuses

23
Q

nerve roots of fallopian tubes’ sensory afferent fibres

A

from T11- L1
