2
Q

The superior hypogastric plexus gives rise to what three other plexuses?

A

Ureteric plexus.

Testicular plexus.

Common iliac plexus.

3
Q

Which anterior rami give rise to the nerve of the quadratus femoris?

A

L4-S1

4
Q

What are the branches of the sacral plexus?

A

Sciatic nerve.

Pudendal nerve.

Superior gluteal nerve.

Inferior gluteal nerve.

5
Q

Which anterior rami give rise to the nerves to the levator ani and coccygeus?

A

S3, S4

6
Q

What nerve contributions form the Coccygeal plexus?

S4 – S5 and coccygeal nerves.

7
Q

From which spinal nerves do the somatic nerves of the lower limb, pelvis, and perineum arise?

A

L4-L5 (lumbar plexus contribution).

S1-Co

8
Q

What is the function of the pudendal nerve?

A

Innervation of the perineum, and sensory afferents for the external genitalia and anal canal (below the pectinate line).

9
Q

What is the function of the coccygeal plexus?

A

Somatic innervation to the coccygeus muscle, part of the levator ani, and the sacral coccygeal joint.

Q

What provides the sympathetic and parasympathetic contributions to the inferior hypogastric plexus?

A

Sympathetic: Right and left hypogastric nerves (from the superior hypogastric plexus), and the sacral splanchnic nerves.

Parasympathetic: pelvic splanchnic nerves.

13
Q
