GENITALS

Question 1

INGUINAL CANAL

Answer 1

= Connective tissue filled cleft between abdominal muscles and their aponeurosis
o PATHWAY for VAGINAL PROCESSES
- Males: Spermatic chord + M.Cremaster
- Females: Round ligament of Uterus

o Caudomedial angle of Inguinal Canal
- Blood, Lymphatic vessels
A/V. Pudenda
- Vasa efferentia of superficial Lnn.
- N.Genitofemoralis

o CLINICAL IMPORTANCE:

• Castration
• Inguinal hernias
• Cryptochidism

Question 2

INGUINAL CANAL

Structures

Answer 2

1. ANNULUS INGUINALIS SUPERFICIALIS
= External opening of the inguinal canal
Borders:
M. Obliquus Externus Abdominis
- Crus Laterale/Pelvina
- Crus Mediale/Femoralis

2. ANNULUS INGUINALIS PROFUNDUS
   = Transversally
   Borders:
   Caudally –> Caudal border of M.obl.int.abd
   Craniomedially –> Lateral border of M.rect.abd
   Craniolaterally–> Lig.Inguinale (part of M.obl.ext.abd)

Question 3

CANALIS FEMORALIS

Answer 3

= Channel, where femoral vessels and nerves go towards hindlimb.

Its opening from abdominal cavity,
underneath inguinal ligament is the
femoral ring (ANULUS FEMORALIS ).

Femoral triangle forms its borders:

1. M. sartorius pars caudalis (rostral),
2. M. Pectineus (caudal),
3. Lig. inguinale (proximal),
4. M. iliopsoas (medial),
5. Femoral fascia (lateral)

Space under inguinal ligament - before canalis femoralis starts - can be divided into:

1. Lacuna vasorum (for femoral vessels) and
2. Lacuna musculorum (for m. iliopsoas).
