Where does the spermatic cord pass through?
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. Is the testicular vein in the spermatic cord? The testicular vein (or spermatic vein), the male gonadal vein, carries deoxygenated blood from its corresponding testis to the inferior vena cava or
What is the spermatic cord in males?
Sep 26, 2014 · 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. It continues into the scrotum, ending at the posterior border of the testes.
What are the three layers of the spermatic cord?
Dec 04, 2010 · Spermatic cord structures enter the pelvic cavity through passageways in the anterior abdominal wall known called inguinal canals.
What is the pathway of sperm through the vas deferens?
The _____ is an opening through which the spermatic cord passes. ... an enlarged part of a tube or canal. spermatic cord. bundle of fibrous connective tissue containing the ductus deferens, blood and lymphatic vessels, and testicular nerve ... prostatic urethra. proximal portion of urethra. membranous urethra. passes through urogenital ...
What is the passageway through which the spermatic cord passes?
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.Aug 10, 2020
What is the spermatic cord and what is its path?
The spermatic cord is the cord-like structure in males formed by the vas deferens (ductus deferens) and surrounding tissue that runs from the deep inguinal ring down to each testicle. Its serosal covering, the tunica vaginalis, is an extension of the peritoneum that passes through the transversalis fascia.
What passes through 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.Aug 15, 2017

What is the structure of the spermatic cord?
Structure. The spermatic cord is ensheathed in three layers of tissue: external spermatic fascia, an extension of the innominate fascia that overlies the aponeurosis of the external oblique muscle. cremasteric muscle and fascia, formed from a continuation of the internal oblique muscle and its fascia. internal spermatic fascia, continuous ...
What is the normal diameter of the spermatic cord?
internal spermatic fascia, continuous with the transversalis fascia. The normal diameter of the spermatic cord is about 16 mm (range 11 to 22 mm). It is located behind the tunica vaginalis.
Can a testicle torsion cause an indirect inguinal hernia?
A collection of serous fluid in the spermatic cord is named 'funiculocele'. The contents of the abdominal cavity may protrude into the inguinal canal, producing an indirect inguinal hernia.
Overview
The spermatic cord is the cord-like structure in males formed by the vas deferens (ductus deferens) and surrounding tissue that runs from the deep inguinal ring down to each testicle. Its serosal covering, the tunica vaginalis, is an extension of the peritoneum that passes through the transversalis fascia. Each testicle develops in the lower thoracic and upper lumbar region and migrates into the scrotum during its descent it carries along with it vas deferens, its vessels, ner…
Structure
The spermatic cord is ensheathed in three layers of tissue:
• external spermatic fascia, an extension of the innominate fascia that overlies the aponeurosis of the external oblique muscle.
• cremasteric muscle and fascia, formed from a continuation of the internal oblique muscle and its fascia.
Clinical significance
The spermatic cord is sensitive to torsion, in which the testicle rotates within its sac and blocks its own blood supply. Testicular torsion may result in irreversible damage to the testicle within hours. A collection of serous fluid in the spermatic cord is named 'funiculocele'.
