17
Q

Lumbosacral trunk spinal cord levels

A

L4-L5

Note: Lumbar contribution to sacral peripheral nerves like the gluteal nerves and sciatic nerves, found medial to psoas major and deep to obturator nerve

18
Q

Lumbosacral trunk source

A

Ventral rami of spinal nerves L4-L5

19
Q

Lumbosacral trunk destination

A

Sacral Plexus

20
Q

Lumbosacral trunk innervates

A

Contributes to sacral plexus nerves like gluteal nerves, sciatic nerve

21
Q

Sacral Ventral Rami spinal cord levels

A

S1-S3

Note: Joins lumbosacral trunk to form sacral plexus in particular sacral component of major lower limb and pelvic nerves; sympathetic chain also contributes. S4+S5 are also part of the plexus but likely hard to see, so they are not included.

22
Q

Sacral Ventral rami source

A

Spinal nerves S1-S3

23
Q

Sacral Ventral rami destination

A

Sacral plexus

24
Q

Sacral Ventral rami innervates

A

Contributes to sacral plexus nerves like the gluteal nerves, sciatic nerve, pudendal nerve
