Part 2 of Prac 3
Adductor Magnus
A deep adductor muscle that originates on the ischium and pubis and inserts on the linea aspera of the femur. Adducts and medially rotates the thigh.
Tibialis Anterior
Anterior muscle of the leg that originates on the lateral condyle of the tibia and inserts on the first metatarsal and cuneiform (one of the tarsals). Dorsiflexes and inverts the foot.
Extensor Digitorum Longus
Anterior muscle of the leg. Originates on the lateral condyle of the tibia and anterior surface of the fibula and inserts on the middle and distal phalanges of digits II-V. Dorsiflexes the foot and extends digits II-V.
Sartorius
Called the "tailor's muscle", the sartorius is the longest muscle in the body. It originates on the ilium and inserts on the medial body of the tibia. Flexes the leg, and flexes and laterally rotates the thigh.
Flexor Digitorum Longus
Deep posterior muscle of leg. Originates on the middle third of the posterior surface of the tibia and inserts on the distal phalanges of digits II-V. Plantar flexes foot and flexes digits II-V.
Flexor Hallucis Longus
Deep posterior muscle of the leg. Originates on the inferior two thirds of the posterior portion of the fibula and inserts on the distal phalanx of the great toe. Plantar flexes foot and flexes the great toe/hallux.
Tibialis Posterior
Deep to the soleus, the tibialis posterior originates on the superior portion of the posterior tibia and fibula and inserts medially on the inferior surface of several tarsals and metatarsals. Inverts and plantar flexes the foot.
Semitendinosus
Hamstrings Group Medial and superficial muscle of the hamstrings group that originates on the ischial tuberosity and inserts on the medial side of the body of the tibia. Flexes the leg and extends the thigh.
Biceps Femoris
Hamstrings Group Lateral muscle of the posterior thigh. Its two heads originate on the ischial tuberosity and linea aspera of the femur and insert on the head of the fibula and lateral condyle of the tibia. Flexes the leg and extends the thigh.
Semimembranosus
Hamstrings Group Medial and deep muscle of the hamstrings group that originates on the ischial tuberosity and inserts on the medial condyle of the tibia. Flexes the leg and extends the thigh.
Fibularis (Pernoeus) Brevis
Lateral muscle of the leg that originates on the body of the fibula and inserts on the fifth metatarsal. Everts and plantar flexes the foot.
Fibularis (Pernoeus) Longus
Lateral muscle of the leg that originates on the lateral condyle of the tibia and head of the fibula and inserts on the first metatarsal and cuneiform. Everts and plantar flexes the foot.
Gracilis
Muscle of the medial thigh that originates on the pubis and inserts on the medial surface of the proximal tibia. Adducts the thigh and flexes the leg.
Adductor Longus
Originates on the pubis and inserts on the linea aspera of the femur. Adducts, flexes, and medially rotates the thigh.
Adductor Brevis
Originates on the pubis and inserts on the linea aspera of the femur. Adducts, medially rotates and flexes the thigh.
Rectus Femoris
Quadriceps Femoris Muscle of the anterior thigh that originates on the anterior ilium and inserts on the tibial tuberosity via the patellar ligament. Flexes the thigh and extends the leg.
Vastus Intermedius
Quadriceps Femoris Originates on the anterior and lateral surfaces of the body of the femur and inserts on the tibial tuberosity. Extends the leg.
Vastus Medialis
Quadriceps Femoris Originates on the linea aspera of the femur and inserts on the tibial tuberosity. Extends the leg.
Vastus Lateralis
Quadriceps Femoris Originates on the proximal femur and inserts on the tibial tuberosity. Extends the leg.
Soleus
Triceps Surae Deep to the gastrocnemius, this muscle originates on the head of the fibula and proximal medial tibia and inserts on the calcaneus via the achilles tendon. Plantar flexes the foot.
Gastrocnemius
Triceps Surae Muscle of the posterior leg. Its two heads originate on the distal posterior femur and insert on the calcaneus via the achilles tendon. Plantar flexes the foot and flexes the leg.
