Q

What’s the role of the fimbriae?

A

The fimbriae uses cilia to create currents to carry the oocyte into the uterine (fallopian) tube from the ovaries since they have no contact

25
What is the isthmus?
narrow organ passage of tissues between the body and the cervix
26
Explain the functions of the uterus
To provide suitable environment for the growth and development of the foetus and to assist in the expulsion of the foetus, placenta and membranes at birth
27
The uterine wall is composed of 3 layers. Which are..
1 - endometrium 2 - myometrium 3 - perimetrium endo - inner myo - muscle peri - surrounding
28
What is the endometrium?
The mucosal lining of the uterine cavity - becomes the 'decidua' during pregnancy - where the embryo will implant
29
Why does the endometrium has numerous uterine glands?
They change in length as the endometrial thickness changes - e.g during menstruation
30
What happens to the endometrium during and after menstruation?
During - part is shed | After - a new layer is formed
31
Define the myometrium
Middle layer of the uterine wall of smooth muscle
32
Define the perimetrium
Outermost layer of the uterine wall, formed by peritoneum
33
Describe the cervix
Narrow neck which projects into the vagina, approx 2.5cm long
34
What is the important role of the cervix?
Protecting the uterus from infection
35
The cervical cavity communicates with...
1 - the vagina via the external opening passage | 2 - the uterine body via the internal opening passage
36
What do the cervical glands secrete?
Mucus that covers the external opening passage and blocks sperm entry except during mid-menstruation cycle
37
Describe the vagina
thin-walled, hollow, fibre-muscular tube lying between bladder and rectum: directed upwards and backwards
38
The vagina comprises of 3 layers, which are:
1 - muscosa 2 - muscle 3 - fascia
39
The vagina extends from the vulva to the cervix, approx ..?..cm long
7.5cm wall length
40
The vagina is made of rugae. What is this?
rugae refers to series of ridges produced by folding of the wall of an organ
41
Describe vaginal rugae
The vagina is lined by moist epithelial cells, smooth muscle layer to maintain tone and ability to stretch during times such as sexual intercourse and childbirth
42
What is the urethra and where is it located?
The passage for urine, embedded in the anterior wall of the vagina
43
Where are vaginal fornices/fornix located?
(latin for arch) located at the upper end of the vagina, surrounding the cervix
44
What is muscosa?
Located near the vaginal orifice forming an incomplete division called the hymen
45
What is the hymen?
The hymen is a thin piece of mucosal tissue that surrounds or partially covers the external vaginal opening
46
What are the vaginal functions?
Passageway for menstrual blood flow, sexual activity and birth, prevention of ascending infection
47
No glands are present in the vagina...why?
Secretions from the cervical glands provide moisture and transudation of serous fluid from blood vessels
48
Describe the mons pubis
fatty pad located over pubic bone, skin and hair covered after puberty
49
Describe labia majora
two thick (outer) folds of fatty skin covered tissue
50
Describe the labia minora
two thinner (inner) skin fold, anteriorly encircles the clitoris, forms to prepuce and a smaller, lower fold called the frenulum just below the prepuce
51
Describe the clitoris
highly sensitive erectile tissue that host many nerve endings for sexual pleasure
52
What is the urethral meatus?
the external opening of the urethra which connects to the bladder
53
Describe the hymen
Thin membrane below the vaginal orifice, ruptures easily from tampons, intercourse and at birth
54
Where are the bartholin's glands (vestibular glands) located?
Ducts which emerge from both sides of the vaginal orifice and inner sides of labia minora.
55
What do the bartholin's glands do?
Mucus secretion to lubricate vulva - increased during sexual arousal
56
Where are the scene's glands located and what do they do?
Located at the mouth of the urethra. Swell during arousal and play a role in female ejaculation
57
Explain the vestibule
Extends from the clitoris to the fourchette, therefore containing urethral and vaginal orifices and vestibular glands (skenes and bartholins)
58
Where is the fourchette located?
Where the labia minor joins posteriorly to the vaginal orifice
59
Where is the perineum located?
Extends from the fourchette to anus, covering pelvic floor muscles. Prone to tears in labour, or cut if necessary
60
What is the age range for puberty?
10-14
61
What is the age range for menopause?
45-55
62
What visibly appears during puberty?
hair and fat accumulates
63
Secretory glands become less active during puberty. True or False?
False. Become more active, more hormones to secrete
64
Labia majora and minora become pigmented with melanin during puberty. What is this?
Melanin is the pigment that gives hair, skin and eyes their colour
65
The clitoris shrinks during puberty. True or False?
False, it enlarges.
66
During puberty vaginal epithelium thickens and...
becomes responsive to oestrogen
67
How does vaginal pH decrease during puberty?
lactobacilli metabolise vaginal epithelium
68
What happens to the size of the uterus and cervix during puberty?
Uterus grows and cervix doubles in length
69
What is meant by epithelium?
The thin tissue forming the outer layer of a body's surface
70
What is lactobacilli?
a rod-shaped bacterium which produces lactic acid which helps destroy pathogenic bacteria
71
Vaginal examinations can flag up issues of sensitivity, informed consent, privacy etc. What other considerations would midwives need to be mindful of before undertaking a VE?
- embarrassment/anxiety - have they had a VE before? - their age? particularly young, vulnerable? - experience of sexual violence? - childhood sexual abuse - FGM
