Editing Anatomy: Groin and Inguinal (section)

== Groin ==

=== Vasculature ===
*'''<span style="color:#ff0000">Posterior to fascia lata</span>'''
*'''<span style="color:#ff0000">Superficial vessels</span>'''
**'''Supply the skin and subcutaneous tissue'''
**'''Branches of the femoral artery (3)'''
**#'''Superficial circumflex iliac artery'''
**#*Smallest of the branches
**#*Pierces through the fascia lata
**#*'''Origin is usually lateral to the saphenous opening'''
**#*Travels superolaterally, in the direction of the anterior superior iliac spine
**#*Supplies
**#**Region of the skin over the lateral third of the inguinal ligament and the iliac crest
**#**Superficial fascia and superficial inguinal nodes along its course
**#*Anastomoses with branches of the deep circumflex iliac, superior gluteal, and lateral circumflex femoral artery
**#'''Superficial epigastric artery'''
**#*Medial to the superficial circumflex iliac artery
**#*Following a more vertical course; ascends anterior to the inguinal ligament up to the region just below the umbilicus
**#*'''Typically originates from the anterior aspect of the femoral artery about 2–5 cm distal to the inguinal ligament, just inferior to the saphenofemoral venous junction'''
**#**Often originates from a trunk that is shared with the superficial circumflex iliac artery
**#*Supplies the skin, superficial fascia, and inguinal nodes in midinguinal area
**#*Branches anastomose with those of the contralateral artery and with the inferior epigastric artery
**#'''Superficial external pudendal artery'''
**#*'''Medial origin on the femoral artery'''
**#**Rarely it may originate from the profunda femoris artery
**#*'''Medial route,''' coursing in the direction of the pubic symphysis where it traverses the spermatic cord in males and the round ligament in females
**#*Supplies cutaneous blood flow to the inferior abdomen, the penis, and the scrotum in males and the labia majora in females
**#*Anastomoses with branches of the internal pudendal artery
**Anastomoses exist between the superficial and deep vessels
*'''<span style="color:#ff0000">Deep vessels</span>'''
**Supplies the muscles and fascia
**'''Deep circumflex iliac'''
***Branches off of the lateral aspect of the external iliac artery
***Supplies the deep lateral groin
**'''Inferior epigastric'''
***Branch of the external iliac artery
***Origin just medial to that of the deep circumflex iliac artery
***Gives off two branches: the pubic and the external spermatic (or cremasteric)
***Forms the lateral border of the inguinal (Hesselbach’s) triangle
