What are the three muscles that are considered the hamstrings?
Biceps femoris (long head)
Semitendinosus
Semimembranosus
What are the three requirements to be considered a hamstring muscle?
- Attach to the ischial tuberosity
- Innervated by the tibial division of the sciatic nerve
- Attach distally to the leg bones
What are the muscles of the anterior compartment of the leg?
Tibialis Anterior
Extensor Hallucis Longus
Extensor Digitorum Longus
Fibularis Tertius
What nerve innervates the anterior leg?
Deep fibular nerve (branch from the common fibular nerve)
What are the muscles of the lateral compartment of the leg?
Fibularis Longus
Fibularis Brevis
What nerve innervates the lateral compartment of the leg>
Superficial fibular nerve (branch from the common fibular nerve)
What are the three muscles that make up the Pes Anserine? Where do they distally attach?
Gracilis
Sartorius
Semitendinosus
Attach to the superior medial portion of the tibia
