The visceral peritoneum is sensitive to touch, heat, cold, and laceration. True/False?
False.
It is the PARIETAL peritoneum.
Venous drainage:
______ -> ______ -> ______
Superficial epigastric v. -> thoracoepigastric v. -> axillary v.

False.
Omentum is only a covering. The neurovasculature is found in the MESENTERY.
Responsible for the wrinkled appearance of the scrotum
Dartos fascia and dartos muscle
Contraction when cold causes the scrotum to wrinkle and reduce its surface area, assisting the CREMASTER MUSCLE in holding it closer to the body.
