Editing Inguinal lymph nodes (section)

==Superficial inguinal lymph nodes==
The '''superficial inguinal lymph nodes''' are the inguinal lymph nodes that form a chain immediately inferior to the [[inguinal ligament]]. They lie deep to the [[fascia of Camper]] that overlies the [[femoral vessel]]s at the medial aspect of the [[thigh]]. They are bounded superiorly by the inguinal ligament in the femoral triangle, laterally by the border of the [[sartorius muscle]], and medially by the [[adductor longus muscle]].

There are approximately 10 superficial lymph nodes. They normally measure up to 2&nbsp;cm in diameter.<ref name="Assessment of lymphadenopathy">{{cite web |title=Assessment of lymphadenopathy |url=http://bestpractice.bmj.com/best-practice/monograph/838/diagnosis/step-by-step.html |access-date=2017-03-04 |website=[[BMJ Best Practice]]}} Last updated: Last updated: Feb 16, 2017</ref>

They are divided into three groups:
* inferior – inferior of the [[saphenous opening]] of the leg, receive drainage from lower legs 
* superolateral – on the side of the saphenous opening, receive drainage from the side buttocks and the lower abdominal wall. 
* superomedial – located at the middle of the saphenous opening, take drainage from the [[perineum]] and [[sex organ|genitals]].<ref>{{Cite web|url=http://www.medilexicon.com/medicaldictionary.php?t=51862|title=Superficial Inguinal Lymph Nodes -- Medical Definition|website=www.medilexicon.com|access-date=2016-05-09|archive-date=2016-05-12|archive-url=https://web.archive.org/web/20160512223255/http://www.medilexicon.com/medicaldictionary.php?t=51862|url-status=dead}}</ref>

=== Afferents ===
They may receive [[lymphatic vessel#Afferent vessels|lymphatic afferents]] from the following as applicable:
* [[integument]] of the [[Human penis|penis]]
* [[scrotum]]
* [[perineum]]
* [[buttock]]
* [[abdominal wall]] below the level of the [[Navel|umbilicus]]
* [[back]] below the level of the [[iliac crest]]
* [[vulva]]
* [[Human anus|anus]] (below the [[pectinate line]])
* the thigh and the medial side of the leg (the lateral leg drains to the popliteal lymph nodes first).

=== Efferents ===
They drain to the deep inguinal lymph nodes.<ref name="Assessment of lymphadenopathy" />
