What is spermatic fascia?

What is spermatic fascia?

The spermatic fascia is a bilayered fascia covering the testis; both layers are derived from abdominal muscle or fascia. The deeper internal spermatic fascia is deep to the cremaster muscle, directly surrounds the spermatic cord and its contents, and is a continuation of the abdominal transversalis fascia.

What forms the internal spermatic fascia?

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.

Where is internal spermatic fascia?

The internal spermatic fascia is a continuation downward of the aponeurosis from the transverse abdominal muscle. This attaches around the deep inguinal ring.

What are the 3 layers of spermatic fascia?

Gross anatomy

• external spermatic fascia (arising from the external oblique aponeurosis)
• cremaster fascia which contains the cremaster muscle (arising from the internal oblique muscle and aponeurosis)
• internal spermatic fascia (arising from the transversalis fascia) 1,2

What are the three layers of spermatic fascia?

We find a double layer here and outside the superficial inguinal ring we might be able to identify 3 layers of spermatic fascia; an external spermatic fascia, a cremesteric fascia, which is muscular and a deep spermatic fascia which is derived from the transversalis layer.

What makes external spermatic fascia?

The external spermatic fascia is derived from the aponeurosis of the abdominal external oblique muscle. This attaches around the superficial inguinal ring.

What forms the Cremasteric fascia?

The cremasteric fascia lies between the more superficial external spermatic fascia and the deeper internal spermatic fascia. It is a continuation of the aponeurosis of the abdominal internal oblique muscle.

What becomes the external spermatic fascia?

The external spermatic fascia is derived from the aponeurosis of the abdominal external oblique muscle. It is acquired by the spermatic cord at the superficial inguinal ring.

Where does the Cremasteric fascia come from?

What are the layers of the testis?

Structure. 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.

What are the components 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.
