What are spermatic cord components?
What are spermatic cord components?
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 are the three parts of the epididymis?
Testicle and Epididymis, Surface The epididymis consists of three parts: head, body, and tail. The head of the epididymis is located on superior pole of testis. It stores sperm for maturation. The body of the epididymis is a highly convoluted duct which connects the head to the tail of the epididymis.
Which component of the spermatic cord is formed from this Aponeurosis?
Cremaster muscle, derived from the internal oblique muscle at the deep inguinal ring. External spermatic fascia, derived from the external oblique aponeurosis at the superficial inguinal ring (present only in the scrotum and not in the inguinal canal)
What are the three coverings of the testes?
The testis is invested by three tunics: the tunica vaginalis, tunica albuginea, and tunica vasculosa. The Tunica Vaginalis (tunica vaginalis propria testis) is the serous covering of the testis.
What is the tunica albuginea made of?
collagen
The tunica albuginea is composed primarily of tough type I collagen with a minority component of more flexible type III collagen and elastin. It is arranged in a bilayer, with inner circular layers and outer longitudinal layers (see Fig.
How do you remember the contents of the spermatic cord?
Mnemonics
- P: pampiniform plexus.
- D: ductus deferens.
- C: cremasteric artery.
- T: testicular artery.
- A: artery of the ductus deferens (deferential artery)
- G: genital branch of the genitofemoral nerve.
- S: sympathetic nerve fibers.
- L: lymphatic vessels.
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.
How spermatic cord is formed?
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 are the coverings of the spermatic cord?
The coverings of the spermatic cord include the external spermatic fascia, cremaster muscle, and internal spermatic fascia. The coverings are originally part of the abdominal wall. The external spermatic fascia is part of the external abdominal oblique and contains the dartos muscle.
What are testes made of?
Each testicle is covered by tough, fibrous layers of tissue called the tunica. The outer layer is called the tunica vaginalis and the inner layer is called the tunica albuginea. The testicle is divided into parts called lobules. Each lobule contains tiny U-shaped tubes called seminiferous tubules.
What tissue layer is tunica albuginea in?
fibrous connective tissue
The tunica albuginea is the fibrous tissue covering of the testis. It is a dense blue-grey membrane, composed of bundles of white fibrous connective tissue, from which it derives its name albuginea, which interlace in every direction….

What is Gubernaculum?
Anatomical terminology. The paired gubernacula (from Ancient Greek κυβερνάω = pilot, steer) also called the caudal genital ligament, are embryonic structures which begin as undifferentiated mesenchyme attaching to the caudal end of the gonads (testes in males and ovaries in females).
The contents of the Spermatic Cord can be easily remember with the Rule of 3’s. 3 arteries: Testicular Artery, Cremasteric Artery, Artery to Vas. 3 veins: Pampiniform plexus, Cremasteric Vein, Vein of Vas. 3 nerves: genital branch of genitofemoral nerve, sympathetics, ilioinguinal nerve (technically runs outside the spermatic cord.
What are the 3 nerves in the spermatic cord?
First Spermatic Cord Contents Mnemonic 3 nerves, 3 arteries, and 3 other things. It is also known as the spermatic cord contents rule of 3’s 3 Nerves: genital branch of the genitofemoral, cremasteric nerve, sympathetic nerve fibers.
What are the fascial coverings of the spermatic cord?
Fascial Coverings. The contents of the spermatic cord are mainly bound together by three fascial layers. They are all derived from anterior abdominal wall: External spermatic fascia – derived from deep subcutaneous fascia (fascia innominata). Cremaster muscle and fascia – derived from the internal oblique muscle and its fascial coverings.
What is the pathway of sperm from epididymis to testes?
Vas deferens – the duct that transports sperm from the epididymis to the ampulla (a dilated terminal part of the duct), ready for ejaculation. Processus vaginalis – projection of peritoneum that forms the pathway of descent for the testes during embryonic development. In the adult, it is fused shut.
