What does external spermatic fascia cover?
The spermatic fascia is a bilayered fascia covering the testis; both layers are derived from abdominal muscle or fascia.
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
Where does external spermatic fascia come from?
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 gives rise to 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 is the function of spermatic fascia?
The internal spermatic fascia is derived from the transversalis fascia. It is acquired by the spermatic cord at the deep inguinal ring. It has very little lymphatic drainage. It is mainly supplied by sensory afferents and the sympathetic nervous system.
What is external oblique?
The external oblique muscle (EOM) is one of the muscles that forms the anterior abdominal wall. Its free inferior border forms the inguinal ligament, and its aponeurotic part contributes to the anterior wall of the inguinal canal.
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.
What is Scarpa fascia?
Scarpa’s fascia is a membranous layer of the anterior abdominal wall. Scarpa’s fascia lies below the Camper’s fascia and above the external oblique muscle. It is connected laterally to the aponeurosis of the external oblique muscle.
What is the internal oblique muscle?
Internal abdominal oblique is a muscle found on the lateral side of the abdomen. It is broad and thin. it forms one of the layers of the lateral abdominal wall along with external oblique on the outer side and transverse abdominis on the inner side. Its fibers are obliquely oriented hence the name.
What forms internal spermatic 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.
Where is the external oblique located?
External abdominal oblique (EO) is a flat superficial abdominal muscle located on the lateral side, with anterior abdominal muscle forms anterolateral abdominal wall.
