Where is the superficial inguinal ring?
The superficial or external ring is the terminal end of the inguinal canal. It is located just superior to the pubic tubercle. The superficial ring has a triangular shape that is made by fibers of the external oblique muscle. These fibers continue to cover the inguinal contents as they descend into the scrotal area.
What are the coverings of the spermatic cord and their origins?
The coverings of the spermatic cord include the following: Internal spermatic fascia, derived from the transversalis fascia at the deep inguinal ring. Cremaster muscle, derived from the internal oblique muscle at the deep inguinal ring.
What is the difference between inguinal canal and spermatic cord?
The key difference between spermatic cord and inguinal canal is that spermatic cord is a collection of vessels, nerves and ducts that run to and from the testes while the inguinal canal is a passage that allows the spermatic cord to pass through.
What is the inguinal ring?
: either of two openings in the fasciae of the abdominal muscles on each side of the body that are the inlet and outlet of the inguinal canal, give passage to the spermatic cord in the male and the round ligament in the female, and are a frequent site of hernia formation : abdominal ring: a : deep inguinal ring.
What are parts of the spermatic cord?
The contents of the spermatic cord include the following:
- Vas deferens.
- Testicular artery.
- Artery of the ductus deferens.
- Cremasteric artery.
- Pampiniform plexus.
- Genital branch of the genitofemoral nerve.
- Parasympathetic and sympathetic nerves.
- Lymphatic vessels.
What nerve exits the superficial inguinal ring?
The ilioinguinal nerve (L1) emerges through the superficial inguinal ring to supply the root of the penis, anterior third of the scrotum and vulva, and an adjoining small area in the upper part of the thigh.
Is the Ilioinguinal nerve in the spermatic cord?
The ilioinguinal nerve is not actually located inside the spermatic cord, but runs outside it in the inguinal canal.
What are the parts of the spermatic cord?
Is the epididymis part of the spermatic cord?
The spermatic cord is a soft and round cable-like structure suspending the testis and epididymis, which originates from the deep inguinal ring, passing through the superficial inguinal ring, descending into the scrotum and ending in the posterior margin of the testicle.
What passes through superficial inguinal ring?
Superficial inguinal ring It is a triangular opening that forms the exit of the inguinal canal, which houses the ilioinguinal nerve, the genital branch of the genitofemoral nerve, and the spermatic cord (in men) or the round ligament (in women).
What goes through the inguinal ring?
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 does the spermatic cord enter the scrotum?
The spermatic cord is formed at the opening of the inguinal canal, known as the deep inguinal ring. This opening is located laterally to the inferior epigastric vessels. The cord passes through the inguinal canal, entering the scrotum via the superficial inguinal ring.
Which is the superficial ring of the inguinal canal?
The superficial (external) ring marks the end of the inguinal canal, and lies just superior to the pubic tubercle. It is a triangle shaped opening, formed by the evagination of the external oblique, which forms another covering of the inguinal canal contents.
Where is the ilioinguinal nerve located in the spermatic cord?
A useful mnemonic to remember the contents of the spermatic cord can be found here. The ilioinguinal nerve runs anterior to the spermatic cord. 1. Shadbolt CL, Heinze SB, Dietrich RB. Imaging of groin masses: inguinal anatomy and pathologic conditions revisited.
Is the spermatic cord covered by the tunica vaginalis?
The spermatic cord is not covered completely by the tunica vaginalis in circle, but only the front of the spermatic cord is covered by the tunica vaginalis. Therefore it is not easy to see the funicular spermatic cord, the tunica vaginalis cavity is fully filled.
