In human anatomy, the groin, also known as the inguinal region or iliac region, [1] is the junctional area between the torso and the thigh. [2] The groin is at the front of the body on either side of the pubic tubercle , where the lower part of the abdominal wall meets the thigh.
The inguinal ligament (/ ˈ ɪ ŋ ɡ w ɪ n ə l / [1] [2]), also known as Poupart's ligament or groin ligament, is a band running from the pubic tubercle to the anterior superior iliac spine. It forms the base of the inguinal canal through which an indirect inguinal hernia may develop.
The femoral triangle is bounded: [2] superiorly (also known as the base) by the inguinal ligament. [2]medially by the medial border of the adductor longus muscle. (Some people consider the femoral triangle to be smaller hence the medial border being at the lateral border of the adductor longus muscle.) [2]
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. It forms the medial part of the posterior wall of the inguinal canal.
It connects to the pectineus muscle on its ventral and superior aspects. [1] It connects to the rectus abdominis muscle, and the abdominal internal oblique muscle, of the anterior abdominal wall. [1] The pectineal ligament is usually around 6 cm long in adults. [2] It is close to the major vasculature of the pelvis, including external iliac ...
The aponeurosis of the abdominal external oblique muscle is a thin but strong membranous structure, the fibers of which are directed downward and medially.. It is joined with that of the opposite muscle along the middle line, and covers the whole of the front of the abdomen; above, it is covered by and gives origin to the lower fibers of the pectoralis major; below, its fibers are closely ...
The muscle which can 'cancel' or to some degree reverse the action of the muscle. Muscle synergies are noted in parentheses when relevant. O (Occurrences) Number of times that the named muscle row occurs in a standard human body. Here it may also be denoted when a given muscles only occurs in a male or a female body.
The gracilis muscle is commonly used as a flap in microsurgery. According to the classification of Mathes and Nahai, it presents a type II blood supply, allowing it to be transferred on its artery derived from the medial circumflex femoral artery. This artery enters the muscle about 10 cm from the pubic symphysis.
