Q

What are the functions of genitofemoral nerve?

A

Motor to cremaster muscle

Sensory to medial thigh

23
Q

What types of fibers are contained within the lumbar splanchnic nerves?

A

Sympathetic fibers, preganglionic

The lumbar splanchnics synapse in the inferior mesenteric ganglion.

24
Q

What is the function of the cremaster muscle?

A

To control the temperature of the testes.

25
Q

What is the innervation of the cremaster muscle?

A

Genital branch of genitofemoral nerve

26
Q

From which layer of the abdominal muscles is the inguinal ligament derived?

A

External oblique muscle

27
Q

What is the relationship of the inguinal ligament to the inguinal canal?

A

The inguinal ligament is the floor of the inguinal canal

28
Q

What areas does the ilioninguinal nerve supply in the male?

A

In the male - to the skin over the root of the penis and upper part of the scrotum.

29
Q

What areas does the ilioninguinal nerve supply in the female?

A

In the female - to the skin covering the mons pubis and labium majorum.

30
Q

What is the relationship of the ilioninguinal nerve to the spermatic cord and the superficial ring?

A

It travels through the superficial ring to join the spermatic cord after running the length of the ilioinguinal ligament.

31
Q

Which layers of the abdominal muscle join to form the conjoint tendon?

A

Internal oblique and transversus muscles

32
Q

What is the function of the conjoint tendon?

A

The conjoint tendon serves to protect what would otherwise be a weak point in the abdominal wall. A weakening of the conjoint tendon can precipitate a direct inguinal hernia.

Reinforces superficial ring

33
Q

Into what vein does the testicular vein drain into on the left? On the right?

A

Right drains into IVC

Left drains into Left renal vein

34
Q

The lacunar ligament is a direct continuation of:

A

Inguinal ligament

35
Q

What is the function of the pampiniform plexus?

A

Venous drainage to testes

Keeps testes cool

36
Q

The veins that make up the pampiniform plexus eventually become:

A

Testicular vein

37
Q

Which nerve supplies the bulbospongiosus muscle?

A

The pudendal nerve supplies the bulbospongiosus muscle.

38
Q

What is the function of the bulbospongiosus muscle?

A

The function of the bulbospongiosus muscle is to aid in ejaculation by squeezing .

39
Q

The deep dorsal vein of the penis drains into:

A

Prostatic plexus

40
Q

From which artery does the dorsal artery of the penis branch?

A

Internal pudendal artery, which is a branch off of internal anterior

41
Q

What artery supplies the corpora cavernosa?

A

Cavernous artery, fed by the internal pudendal artery

42
Q

The inferior epigastric artery is a branch of:

A

External iliac artery

43
Q

With what artery does the inferior epigastric artery anastomose?

A

Superior epigastric artery

44
Q

What is the function of the seminal vesicles?

A

The seminal vesicles secrete a significant proportion of the fluid that ultimately becomes semen. Lipofuscin granules from dead epithelial cells give the secretion its yellowish color.

Q

Where do the ejaculatory ducts enter the prostatic urethra?

A

2 holes next to the utricle on the colliculus

Q

Where do the prostatic ducts enter the prostatic urethra?

A

There are lots of little prostatic ducts in the prostatic sinuses

Q

The ___1___ and ___2___ join to form the ejaculatory ducts.

A

Vas deferens (ampulla) and seminal vesicles

48
Q

What arteries are contained within the mesosalpinx?

A

Uterine and ovarian arteries

49
Q

Which vessels and nerves are contained within the suspensory ligament of the ovary?

A

Ovarian artery and vein

50
Q

What is the function of the round ligament of the uterus?
