What is inguinal triangle?
What is inguinal triangle?
The Hesselbach triangle, also called the inguinal triangle, is a region of the lower, anterior abdominal wall, or groin, that was first described by Frank Hesselbach, a German surgeon and anatomist, in 1806. It describes a potential area of weakness in the abdominal wall, through which a hernia can protrude.
Where is inguinal located?
Overview. The inguinal region of the body, also known as the groin, is located on the lower portion of the anterior abdominal wall, with the thigh inferiorly, the pubic tubercle medially, and the anterior superior iliac spine (ASIS) superolaterally.
Which hernia goes through Hesselbach’s triangle?
Inguinal (Hesselbach’s) Triangle – Borders – Direct Hernia – TeachMeAnatomy.
What is the inguinal point?
Mid-inguinal point – halfway between the pubic symphysis and the anterior superior iliac spine. Midpoint of the inguinal ligament – halfway between the pubic tubercle and the anterior superior iliac spine (the two attachments of the inguinal ligament). The opening to the inguinal canal is located just above this point.
How is linea alba formed?
In humans, the linea alba runs from the xiphoid process to the pubic symphysis down the midline of the abdomen. The name means white line as it is composed mostly of collagen connective tissue, which has a white appearance. It is formed by the fusion of the aponeuroses of the muscles of the anterior abdominal wall.
Why is it called triangle of doom?
The vas deferens and the gonadal vessels form the boundaries of a so-called ‘triangle of doom’ [18] . This tri- angle of doom contains the external iliac artery and vein. No dissection or other activity whatsoever should be per- formed in this area, as an injury to either of these vessels could be fatal.
How inguinal canal is formed?
The anterior wall of the canal is formed by the external oblique aponeurosis; the posterior wall is formed by the inguinal ligament and conjoined tendon. The oblique direction of the inguinal canal allows for the posterior and anterior walls to coapt with increases in intraabdominal pressure.
What are inguinal canals?
The inguinal canal is a passage in the lower anterior abdominal wall located just above the inguinal ligament. It functions as a passageway for structures between the intra- and extra-abdominal structures. In males, it transmits the spermatic cord, gonadal vessels, and lymphatics.
What does linea alba mean?
[ ăl′bə ] n. A fibrous band that runs vertically along the center of the anterior abdominal wall and receives the attachments of the oblique and transverse abdominal muscles. white line.
What is the innervation of the linea alba?
Linea alba generally lacks blood supply and innervation, but a few small blood vessels cross to the opposite side over its anterior surface. Due to this, it is a common incision and puncture site in abdominal surgery and suprapubic bladder catheterization, respectively. The linea alba is widest around the umbilicus.
