B) Dartos m.
C) Median septum
D) Cremaster m.
E) Dartos and cremaster mm.

E) Dartos and cremaster mm.
Explanation: Both the dartos and cremaster muscles respond to temperature changes by contracting to regulate the temperature of the testes.

Which vessel contributes to the formation of the portal vein?
A) Superior mesenteric v.
B) Right renal v.
C) Testicular v.
D) Inferior rectal v.
E) Inferior vena cava

A) Superior mesenteric v.
Explanation: The superior mesenteric vein is one of the major contributors to the formation of the portal vein, which carries blood from the gastrointestinal tract to the liver.

C) Is in the upper right quadrant of the abdomen
D) Is located between the ileum and the jejunum
E) Has the lumen of the ileum opening into it

E) Has the lumen of the ileum opening into it
Explanation: The cecum is the first part of the large intestine and receives the ileum's contents, making option E the correct statement.

Which vessel contributes to the formation of the portal vein?

Superior mesenteric vein.

p.2
Scalp Anatomy and Hematoma Formation

Where does a subdural hematoma result from blood collecting?

Between the arachnoid and the dura mater.

D) T4
E) T6

D) T4
Explanation: The boundary between the superior and inferior mediastinum is defined by a line projecting from the sternal angle to the T4 vertebra.
