Study Notes
Intrinsic Foot Muscles: 1st Layer
-
Abductor Hallucis
- Innervated by the medial plantar nerve (S1, S2)
- Responsible for abduction of the metatarsophalangeal (MTP) joint of the first toe
-
Flexor Digitorum Brevis
- Also innervated by the medial plantar nerve (S1, S2)
- Facilitates flexion at both the MTP and distal interphalangeal (DIP) joints for toes 2-5
-
Abductor Digiti Minimi
- Innervated by the lateral plantar nerve (S2, S3)
- Functions include abduction of the MTP joint of the fifth toe
- Assists in flexion at the MTP joint of the fifth toe
