Abdomen Cont Flashcards
This is between the median and medial folds
Supervesical fossae
This is between the medial and lateral folds
-AKA hasselbach triangle
Medial inguinal fossae
This is lateral to the lateral folds
-most common area for an inguinal hernia
Lateral inguinal fossae
What are the boundaries of the inguinal triangle? (Hasselbachs triangle)
- Rectus abdominus m
- Inferior epigastric a & v
- Inguinal ligament
Where do the testes develope
Retroperitoneal
This guides the testes
Gubernaculum
Describe the intra and extra abdominal part of the gubernaculum
- Intra- extends from testes to the deep ring
- Extra- deep ring to scrotum
What accompanies the testes to the deep ring?
- Ductus deferens
- Testicular a & v
- Autonomic nn
- Lymphatics
This layer entirely covers the testes and epididymis
Tunica vaginalis
Patent processus vaginalis
Connection between the tunical vaginalis and the peritoneal cavity
Fluid collection around the testes
Hydrocele
Fancy word for undescended testes
Cryptorchisidism
What is the gubernaculum of the female?
The round ligament of the uterus and the ovarian ligament
-both are remnants of the gubernaculum
Where are the attachments of the gubernaculum of the uterus?
- Attaches from the caudal pole of ovaries to labia majora
- attaches to the uterus along the way
_____ interrupts the descent and splits the gubernaculum into 2 separate support structures…. _____ & _____
The uterus
- Ovarian ligament
- Round ligament of the uterus
This anchors the ovary to the uterus
Ovarian ligament
This fixes the uterus to the anterior body wall by attaching into fascia on the labia majora
Round ligament of the uterus
What are the contents of the spermatic cord?
- Ductus deferens
- Testicular artery
- Pampiniform plexus
- Autonomic nerves
- Genetal branch of Genitofemoral Nerve
- Lymphatic vessels
Where does the spermatic cord begin and end?
- Deep inguinal ring
- Posterior aspect of the testes
This is a muscular tube which conveys sperm from the epididymis to the ejactulatory duct (within the prostate)
Ductus deferens
This is the blood supply to the testes and epididymis
-A branch off of the aorta
Testicular artery
These empty or converge into the right and left testicular veins
Pampinform plexus
This structure is only innervated by sympathetic nerves
Testicular artery
This structure has both sympathetic and parasympathetic innervation
Ductus deferens
This nerve supplies the cremaster muscle
The genital branch of the genitofemoral nerve
What is the tunica vaginalis derived from?
Parietal and visceral layers of peritoneum
What is the internal spermatic fascia derived from?
Transversalis fascia
What is the cremaster muscle derived from?
Inferior internal oblique fibers
What is the cremaster fascia derived from?
Internal oblique aponeurosis
What is the external spermatic fascia derieved from?
External oblique and aponeurosis
What muscle does not contribute to the cord
Transverse abdominal muscle
Is the peritoneum continuous through the scrotum
Nope
Layers of the spermatic cord from internal to external
- Tunica vaginalis
- Internal spermatic fascia
- Cremaster muscle
- Cremaster fascia
- External spermatic fascia
- Dartos muscle
- Dartos fascia
- Skin
This is a smooth muscle in the subcutaneous layer that attaches to the skin
-aids in testicular elevation
Dartos muscle
