What is the shutter mechanism of inguinal canal?
1. The inner shutter mechanism is the movement between transversus abdominis and the transversalis fascia. It is located at the deep inguinal ring at the layer of transversus abdominis, which works alongside the transversalis fascia and is thought to be the most significant in maintaining the canals integrity.
What is shutter mechanism of internal oblique?
The arching fibres of the internal oblique and transversus abdominus contract when the muscles of the abdomen contract. This acts as a shutter on the posterior wall to protect it from herniation. This is termed the Shutter Mechanism.
What is Bubonocele hernia?
Medical Definition of bubonocele : an inguinal hernia especially : a hernia in which the hernial pouch descends only as far as the groin and forms a swelling there like a bubo.
What is the pathophysiology of hernia?
It occurs as a result of the deep inguinal ring failing to close during embryogenesis after a testicle has moved through it. Once bowel or other abdominal tissue moves into and enlarges the empty space, a visible bulge forms and the hernia becomes clinically evident.
What is the 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.
What is the conjoined tendon?
The conjoint tendon (previously known as the inguinal aponeurotic falx) is a sheath of connective tissue formed from the lower part of the common aponeurosis of the abdominal internal oblique muscle and the transversus abdominis muscle, joining the muscle to the pelvis.
What is the management of hernia?
Open surgery, in which a cut is made into the body at the location of the hernia. The protruding tissue is set back in place and the weakened muscle wall is stitched back together. Sometimes a type of mesh is implanted in the area to provide extra support. Laparoscopic surgery involves the same type of repairs.
What is Scarpa fascia?
Scarpa’s fascia is a membranous layer of the anterior abdominal wall. Scarpa’s fascia lies below the Camper’s fascia and above the external oblique muscle. It is connected laterally to the aponeurosis of the external oblique muscle.
What is the Endoabdominal fascia?
Parietal abdominal fascia (endoabdominal fascia) may be the fascia that covers the abdominal cavity, or a generic term including extraperitoneal and visceral fascia. Transversalis fascia is the inner epimysium of transversus abdominis muscle; no separate deep investing fascia exists.
