Lumbosacral plexus... Superior gluteal and inferior gluteal: Posterior Femoral cutaneous: Sciatic: Pudendal:
Superior gluteal and inferior gluteal: L4-S2
Posterior Femoral cutaneous: S1-S3
Sciatic: L4-S3

Distal to the knee =
Distal to elbow =
caudal
Rectus femoris... Origin: Insertion: Action: Innervation:
Origin: anterior inferior iliac spine
Insertion: tibial tuberosity by patellar ligament
Action: flexes hip, extends knee
Innervation: femoral nerve
Evolutionary grouping of elevators (dorsal) musculature:
extensors or abductors
Evolutionary grouping of ventral musculature:
flexors or adductors
The sartorius, adductor longus, and inquinal ligament make up what?
the femoral triangle
The superior gluteals:
The inferior gluteals:
The superior gluteals: medius and minimus
The inferior gluteals: maximus
What’s deep to the gluteal musculature and is the “last thing to cover the sciatic nerve before it crosses a bunch of other musculature”?
piriformis
If it originates from the pubis, the quadrant is…
and it MUST be innervated by…
Cranial/ventral
Obturator nerve
The little “hole” in the adductor magnus is the…
Why is it there?
Adductor hiatus
Vessels pass through
If it originated from the ischial tuberosity, the quadrant is…
and it MUST be innervated by…
unless it doesn’t cross the knee, then it’s by…
Caudal/ventral
Tibial nerve
Tibial portion of sciatic nerve
What is the quadrant of the gastrocnemius?
Caudal/ventral
