What is in the first layer of the foot? What innervates them?
- Abductor Digiti Minimi
- lateral plantar nerve - Flexor Digitorum Brevis
- Abductor Hallucis
- medial plantar nerve

What is lateral deviation of the great toe?
Hallux Valgus
**Tissue surrounding deviated area swells -> swelling leads to frction -> Friction causes bursa to form.
