24
Q

What is the perimetrium?

A

The outermost layer of connective tissue

25
What is the myometrium?
The middle and thickest layer of smooth muscle
26
Why is the myometrium the thickest layer?
For contractions during childbirth
27
What is the endometrium?
The innermost layer of columnar epithelium, uterine glands and arteries. This is the layer that grows and sheds during menstrual cycles
28
What is the cervix?
A canal that provides passage between the uterine cavity and vagina, consists of three parts
29
What are the three parts of the cervix?
The external os, cervical canal, internal os
30
What does the cervix produce?
Cervical mucus to protect against infection and regulate sperm transport
31
What is the vagina?
A fibromuscular, distensible female copulatory organ that functions as par of the birth canal
32
Where is the vagina?
Between the urinary bladder and rectum. It extends from the perineum to the cervix
33
What is the blood supply to the ovaries?
Ovarian arteries
34
What is the blood supply to the uterus?
Uterine artery
35
What is the blood supply to the vagina?
Vaginal artery
36
What are the branches off the urtrine artery?
The arcuate and radial arteries
37
What are the branches off the radial arteries?
Spiral and straight arteries
38
What happens to the spiral artery?
It is remodelled during pregnancy and makes up the bulk of period blood
39
What are the ovaries?
The female gonads, are bilateral structures that sit lateral and posterior to the uterus, within the lateral portion of the true pelvic cavity
40
What are the two components of the ovary?
The outer cortex and inner medulla
41
What is the outer cortex made from?
Follicles
42
What is in the inner medulla made from?
Connective tissue, blood/lymphatic vessels and nerves
43
What occurs in the ovarys?
Oogenesis and hormone production
44
Where do oocytes develop?
Within the follicles of the cotrex
45
What are the major ligaments of the female reproductive system?
The suspensory ligament, ovarian ligament, round ligament and broad ligament
46
What is the suspensory ligament?
A thin fold of the parietal peritoneum which attaches to the lateral margin of the ovary and extends to the lateral pelvic sidewall
47
What is the ovarian ligament?
A fibrous band of tissue that connects the ovary to the side of the uterus
48
What is the round ligament?
Wraps around uterine tube
49
What is the broad ligament?
Peritoneum that folds and pressed over structures to create other ligaments
50
What are the ligaments created by the broad ligament?
Mesometrium, mesosalpinx and mesovarium
51
What is the mesometrium?
The largest part of the broad ligament, a double-layered fold of the peritoneum that connects behind the uterus
52
What is the mesosalpinx?
The fold of peritoneum that encloses and supports the uterine tube
53
What is the mesovarium?
The portion of the broad ligament of the uterus that connects behind the ovaries
54
Where does the uterus lie?
Posterior to the bladder and anterior to the rectum
55
What is formed between the uterus and bladder?
Vesicouterine pouch
56
What is formed between the uterus and rectum?
Rectouterine pouch aka the pouch of douglas
57
What are the breasts?
Composed of glands and fat that lie on the pectoralis major muscles and function to nourish infants
58
What is the structure of the breast?
Lobes form lobules that form alveoli -> lactiferous ducts -> lactiferous sinuses that open at nipple pores
59
What supports the glands in the breast?
Suspensory ligaments
