Question 1

Innervation of skin of thigh

For presentation mostly

Answer 1

Anterior (medial to lateral): Ilioinguinal nerve (L1, maybe T12), genitofemoral nerve (L1-L2), lateral cutaneous branch of subcostal nerve (T12), cutaneous branch of obturator nerve (L2-L4), anterior cutaneous branches of femoral nerve (lateral group, L2-L4) and lateral cutaneous nerve of thigh (anterior branches, L2-L3)

Posterior (medial to lateral): Medial Clunial nerves (posterior rami, S1-S3), Superior clunial nerves (posterior rami, L1-L3), Lateral cutaneous branch of ilio-hypogastric nerve (L1, sometimes T12), Lateral cutaneous nerve of thigh (posterior branches, L2-L3), inferior clunial nerves (S2-S3), cutaneous branches of obturator nerve (L2-L4), some anterior cutaneous branches of femoral nerve (medial group, L2-L4), posterior cutaneous nerve of thigh (S1-S3)

Question 2

Anastamoses of thigh

Answer 2

Lateral circumflex femoral artery:
Transverse branch with medial circumflex femoral artery
Ascending branch with superior gluteal artery
Descending branch with genicular arteries (at knee)

Question 3

Answer 3

A lot in here.

Question 4

Spring ligament

Answer 4

plantar calcaneonavicular ligament

Question 5

short plantar ligament

Answer 5

plantar calcaneocuboid ligament

Question 6

What ligaments/factors support the arches of the foot?

Answer 6

The shape of the cuboid, cuneiform bones, and bases of the metatarsal maintain the transverse arch.
The longitudinal arches are maintained by bone shape, but also the long plantar ligament, the plantar calcaeneocuboidal ligament, the plantar aponeurosis, and the plantar calcaneonavicular ligament

The flexor hallucis and digitorum longus maintain the longitudinal arch and the fibularis longus and tibialis posterior maintain the transverse arch.
