Q
WTN
Structures opening in Vestibule
A
- Anterior → External urethral meatus
- Posterior → External vaginal orifice
- On each side → duct of Bartholin’s gland
25
Def of **Vestibular Bulbs**
Two oblong erectile tissues, lying on each side of the vaginal orifice and seen on straining.
26
# VIP
**Vestibular Bulbs** are Homologous to .....
Corpora spongiosa in male.
27
Site of **Vestibular Bulbs**
Deep to bulbocavernosus muscles & anterior to Bartholin's glands.
28
# WTN
Def of **Bartholin Glands (Greater Vestibular Glands)**
Modified racemose sebaceous glands
29
# WTN
**Bartholin Glands (Greater Vestibular Glands)** is Homologous to .....
Cowper's glands in male.
30
# wtn
Sites of **Bartholin Glands (Greater Vestibular Glands)**
- Posterior 1/3 of labia majora in contact with posterior parts of vestibular bulbs
31
# WTN
**Bartholin Glands (Greater Vestibular Glands)**
- Ducts
- Each gland has a duct of about 2 cm long that passes between the hymen and labia minora to open in the vagina.
- The duct openings are not seen except when inflame d or obstructed
32
# WTN
**Bartholin Glands (Greater Vestibular Glands)**
- Applied Anatomy
33
Applied Anatomy of **Bartholin Glands (Greater Vestibular Glands)**
- Secrete .....
- thin mucoid alkaline fluid during sexual excitement which acts as coital lubricant & has antimicrobial activities.
34
Applied Anatomy of **Bartholin Glands (Greater Vestibular Glands)**
- If any swelling appears at posterior 1/3 of Jabium majus
considered Bartholin's gland swelling.
35
Applied Anatomy of **Bartholin Glands (Greater Vestibular Glands)**
- If duct opening is seen
means obstruction or inflammation.
36
Applied Anatomy of **Bartholin Glands (Greater Vestibular Glands)**
- It gland is surgically removed
may lead to severe Hge as it is in contact with posterior part of vestibular bulb.
37
Applied Anatomy of **Bartholin Glands (Greater Vestibular Glands)**
- Bartholin Gland Carcinoma
drains directly to deep inguinal LNs.
38
Marsupialization of Bartholin's duct cyst
39
Def of **Hymen**
- It is a double layered mucous membrane that closes the lower vaginal orifice in the virgin.
- It has an opening for the menstrual blood to pass
40
# MCQ
Shapes of **Hymenal Opening**
41
**Hymen**
- Applied Anatomy
42
Applied Anatomy of **Hymen**
- If it is imperforate
causes cryptomenorrhea.
43
Applied Anatomy of **Hymen**
- It is torn by ist coitus unless .....
- opening is patulous or hymen is elastic (so, intact hymen isn't absolute proof of virginity).
44
Applied Anatomy of **Hymen**
- It may be torn by .....
trauma (so, ruptured hymen isn't indicator of coitus).
45
# MCQ
Applied Anatomy of **Hymen**
- It is torn more & more during 1st vaginal delivery & remnants of hymen in parous women are called .......
caranculae myrtiformis.
46
Depression () hymen & fourchette is called ......... which is found only in virgins.
fossa navicularis
47
48
Blood Supply to **Vulva**
49
# MCQ
Blood Supply to **Vulva**
- Arterial
Internal “main” and external pudendal arteries.
50
Blood Supply to **Vulva**
- Venous
corresponding to the arteries
51
# WTN
Lymphatic Drainage of **Vulva**
superficial and deep femoral and inguinal L.N
52
Nerve Supply of **Vulva**
- Pudendal nerve “main” "from S2, S3, S4 motor and sensory"
- ilioinguinal nerve,
- genital branch of genitofemoral nerve
- posterior cutaneous nerve of the thigh.
53
Origin of **Pudendal Nerve**
S2, S3 & S4.
54
Course of **Pudendal Nerve**
- Leaves pelvis through greater sciatic foramen & crosses behind ischial spine & curls around it then passes through lesser sciatic foramen to enter pelvis again & pass in pudendal canal (Alcock's canal) in ischiorectal fossa.
