What passes through the inguinal canal in males?
There are two known nerves that pass within the structures of the inguinal canal. These nerves are the ilioinguinal and the genitofemoral nerves. [1] A third nerve, iliohypogastric nerve, supply sensation to the skin above the genitalia does not pass through the inguinal canal.
What artery goes through the inguinal canal?
The cremasteric artery (formerly known as the external spermatic artery) supplies the cremaster as well as other fascial layers of the spermatic cord. The artery arises from the inferior epigastric artery and traverses the inguinal canal. It also shares anastomoses with the testicular artery.
What is the relationship of the inferior epigastric artery to the deep inguinal ring?
The inferior epigastric artery arises from the external iliac artery immediately superior to the inguinal ligament. It ascends medially to the deep inguinal ring towards the midline while running posterior to the spermatic cord and anterior to the transversalis fascia.
What artery is inferior to inguinal ligament?
Palpation of the femoral artery is only possible below the inguinal ligament at the mid-inguinal point. The midpoint of the inguinal ligament (the midpoint between the ASIS and the pubic tubercle) is just lateral to the mid-inguinal point.
Which normally pass through the inguinal canals quizlet?
In men, spermatic cord passes through inguinal canal, to supply & drain the testes. In women, round ligament of uterus traverses through the canal. -peritoneal sac enters the inguinal canal via the deep inguinal ring.
Why are inguinal canals larger in males?
The inguinal canals are the two passages in the anterior abdominal wall of humans and animals which in males convey the spermatic cords and in females the round ligament of the uterus. The inguinal canals are larger and more prominent in males….

How deep is the inferior epigastric artery?
The inferior epigastric artery is a direct branch off the external iliac artery. This artery continues moving superiorly and medially for 4–6 cm before it enters the rectus abdominis muscle.
What does inferior epigastric artery supply?
The inferior epigastric artery (IEA) is a major blood vessel that supplies the anterior abdominal wall. It arises from the external iliac artery, proximal to the inguinal ligament.
What does inferior epigastric supply?
What is the location and contents of the inguinal canal for male and female quizlet?
Which tube transports sperm from the ductus deferens to the prostatic urethra?
Sperm then travels through the deferent duct through up the spermatic cord into the pelvic cavity, over the ureter to the prostate behind the bladder. Here, the vas deferens joins with the seminal vesicle to form the ejaculatory duct, which passes through the prostate and empties into the urethra.
What does an inguinal hernia feel like in a man?
A burning or aching sensation at the bulge. Pain or discomfort in your groin, especially when bending over, coughing or lifting. A heavy or dragging sensation in your groin. Weakness or pressure in your groin.
Where is inferior epigastric artery?
The inferior epigastric artery arises commonly from the external iliac artery just superior to the inguinal ligament. This artery runs superiorly in the transversalis fascia to enter the rectus sheath below the arcuate line, and finally anastomoses with the superior epigastric artery [1].
What does the epigastric artery supply?
The superficial epigastric artery supplies the superficial tissue of the abdominal wall; the superior and inferior epigastric arteries make an anastomosis with each other and supply the muscles of the abdominal wall.
What are the contents of the inguinal canal?
The contents of the inguinal canal in males consist of the spermatic cord (with the genital branch of the genitofemoral nerve) and the ilioinguinal nerve. For females, the contents include the round ligament, genital branch of the genitofemoral nerve, and the ilioinguinal nerve.
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.
What is the inferior epigastric artery?
The inferior epigastric artery is a branch of the external iliac artery. It is found on the anterior abdominal wall, passing superomedially from the inguinal canal towards the midline.
What is the difference between the inferior epigastric and obturator?
The pubic branch of the inferior epigastric artery is then considered as the site of origin of the obturator artery, and is referred to as the aberrant or replaced obturator artery. The inferior epigastric may also be doubled. Relatively often, the artery can be referred to as the deep inferior epigastric artery when a superficial one is present.
Where is the opening to the inguinal canal located?
Clinically it is important to note that the opening to the inguinal canal is located laterally to the inferior epigastric artery. During development, the tissue that will become gonads (either testes or ovaries) establish in the posterior abdominal wall, and descend through the abdominal cavity.
What artery anastomoses with the superior epigastric artery?
It anastomoses with the superior epigastric artery. Along its course, it is accompanied by a similarly named vein, the inferior epigastric vein. These epigastric vessels form the lateral border of Hesselbach’s triangle, which outlines the area through which direct inguinal hernias protrude.
