Q

what is the broad ligament and what does it contain ?

FROM L

A
  • Fallopian tubes
  • Round ligament x uterus
  • Ovarian ligament
  • Mesovarium attaches the ovaries to the posterior broad ligament

Lymphatic Vessels and nerves

2
Q

What are the ligaments of the uterus ?

4

A

1) Ovarian ligament= ovary to uterus connection
2) Mesovarium + suspensory ligaments= Broad Ligament =laterally
3) Utero-sacral ligament ( anchors uterus to sacrum )=posteriorly
4) Round ligament = anchors uterus anteriorly, through inguinal canal

3
Q

Uterus relations

A

Anterior :
1-Vesico uterine pouch
2-Superior surface of the bladder

Posterior :
1-Recto-uterine pouch

Laterally:
-Broad ligament

4
Q

course and relations of the ovarian arterys

A
  • At the level of the cervico-uterine junction, the uterine artery divides into an ascending and descending branch.
  • Ascending branch: passes superiorly along the lateral wall of the body of the uterus towards the Fallopian tube.

-Descending branch: passes inferiorly towards the vagina. This vaginal branch anastomoses with branches of the vaginal artery .

5
Q

what are the parts of the fallopian tube?

4

A

1) Infundibulum -envelopes the ovary to capture the ovulated egg, the Fimbriae = hang from infundibulum
2) Ampulla -wide, thin walled = fertilisation occurs here
3) Isthmus = narrow section
4) Intramural portion = lies within uterine wall and opens into uterine cavity

The fimbriae of the uterine tube, also known as fimbriae tubae, are small, fingerlike projections at the end of the fallopian tubes,

6
Q

Anatomy of the breast

5

A
  • 15-20 lobules in adipose tissue
  • Lobulues separated by fibrous tissue/septa ( from subcutaneous tissue –>chest wall)
  • suspensory ligaments connect fat to chest wall
  • lactiferous sinus =>opens into the nipple
  • Lactiferous Ducts around the sinus
7
Q

Lymphatic drainage of the breast
(4)
In examination what do u need to remember ?

A

Breast tissue extends into the axilla so when you examine the patient , make sure to continue until the axilla

  • majority (75%)= axillary lymph nodes
  • Parasternal nodes ( inferior region of breast )
  • Abdominal nodes
  • also can drain to the opposite breast
8
Q

what are the parts of the uterus

5

A

1) opening of fallopian tubes
2) Fundus
3) Body
4) Cervix leads to Vagina

The positions is in anti flexion, and anti-version (over hangs uterus)

9
Q

Anatomy of the external vagina

A

1) Labium majus
2) Labium minus
3) Vestibule of vagina

10
Q

Lymph drainage of ovaries

A

1) Upper region = Lumbar lymph nodes

2) Lower region = external iliac lymph nodes

11
Q

Identify and describe the anatomy and relations of the male reproductive organs
(4)

A
  • Testes = lie within scrotum pouch, containing Dartos muscle
  • covered with tunica albuginea
  • 200-300 lobules , each with 1-3 seminiferous tubules
  • Seminiferous tubules come together to form Rete testis—>efferent (exit) ductules –>epididymus
Blood supply :
1-Testicular artery 
2-Pampiniform plexus 
3-Testicular vein --->IVC
4- Left Testicular --->Left renal vein
12
Q

Identify and describe the spermatic cord and its contents
(3 fascial layers)
Papers Don’t Contribute To A Good Specialist Level

A

External spermatic Fascia => from external oblique aponeurosis
Cremasteric Fascia =>internal Oblique aponeurosis
Internal Spermatic Fascia => transversalis

Papers Don’t Contribute To A Good Specialist Level
P: pampiniform plexus
D: ductus deferens
C: cremasteric artery
T: testicular artery
A: artery of the ductus deferens (deferential artery)
G: genital branch of the genitofemoral nerve
S: sympathetic nerve fibres
L: lymphatic vessels

13
Q

Identify and describe the course, relations and distribution of the testicular artery

A

The testicular artery, also known as the internal spermatic artery, is a branch of the abdominal aorta. It arises in the abdomen and reaches the scrotum by traversing the spermatic cord.

  • While the right testicular artery passes posterior to the ileocolic and middle colic arteries and the distal ileum, and anterior to the inferior vena cava.
  • They both enter the same sided deep inguinal ring and continue towards the testes through the spermatic cord.
14
Q

Identify and describe the location of the recto-vesical pouch

A

-
Rectovesical pouch is the forward reflection of the peritoneum from the middle third of the rectum to the upper part of the bladder in males

15
Q

Identify and describe the anatomy of the pelvic floor in the male

A
16
Q

Describe the lymphatic drainage of the pelvis in the male

A

-Internal iliac lymph nodes

17
Q

describe the epididymis
what does it do ?
parts ?

A

1) Vas deferens (ductus deferens )= tail of epididymis , body, head
- storage of the sperm
2) during ejaculation , the sperm are propelled along the head –>tail
travel along vas deferens within spermatic chord

18
Q
male urethra (3) 
- 3 parts and glands in last part ?
A

1) Prostatic Urethra
2) Membraneous Urethra
3) Spongy urethra

internal urethral sphincter = smooth muscle under sympathetic control
External uretheral spincter = skeletal muscle via pudendal nerve (somatic )

proximal portion of spongy urethra = bulbourethal Cowper’s glands = alkaline mucous

19
Q

Penis anatomy

3 layers

A
outlet for urine and semen
3 bodies of erectile tissue :
1) Corpora cavernosa: 2 lateral layers 
2)Corpus spongiosum: inner 2 layers 
3)glans penis (middle ) = terminates via the navicular fossa --->external urethral orifice
