Muscles Flashcards
Caudofemoralis
Location: superficial; connected to tail; runs perpendicular to tail; separates tail from body
Origin: Caudal vertebrae
Insertion: Patella
Gluteus medius
Location: above gluteus maximus
Origin: Ilium, sacral and caudal vertebrae
Insertion: Greater trochanter of the femur
Gluteus Maximus
Location: superficial; located between the caudofemoralis and the gluteus medius
Origin: Sacral and caudal vertebrae
Insertion: greater trochanter of the femur
Tensor fasciae latae
Location: superficial; runs alongside gluteus medius and gluteus maximus
Origin: ilium
Insertion: fascia of thigh
Rectus femoris
Location: deep; above vastus medialis and below vastus lateralis; only quad muscle that doesn’t insert in the femur
Origin: Ilium
Insertion: patella
Vastus lateralis
Location: deep; highest hind limb muscle; anterior to the femur
Origin: shaft of the femur and the greater trochanter
Insertion: patella
Vastus intermedius
Location: deep to the rectus femoris
Origin: Shaft of the femur
Insertion: Patella
Vastus medialis
Location: deep, caudal to the rectus femoris
Origin: shaft of the femur
Insertion: Patella
Sartorius
Location: superficial muscle on the medial surface of the thigh; runs above the tensor faciae latae and gluteus medius; farthest away from midline
Origin: crest of the illium
Insertion: Fascia of the knee and proximal end of the tibia
Gracillis
Location: inner thigh; large; superficial
Origin: pubic symphysis and ischium
Insertion: proximal end of the tibia
Semitendonosus
Location: deep to the biceps femoris and caudal relative to the semimembranosus; runs down from tail; parallel to tail; perpendicular to caudafemoralis
Origin: ischial tuberosity
Insertion: patella and tibia
Semimembranous
Location: deep to the biceps femoris; right under the biceps femoris
Origin: Ischial tuberosity
Insertion: medial epicondyle of the femur
Biceps femoris
Location: largest muscle on the lateral surface of the thigh; covers the semimembranosus
Origin: Ischial tuberosity
Insertion: patella and tibia
Abductor femoris
Location: above the abductor femoris; small; triangular
Origin: pubis and ischium
Insertion: shaft of the femur
Abductor longus
Location: deep; below abductor femoris; larger than femoris
Origin: pubis
Insertion: proximal end of the femur
Gastrocnemius
Location: muscle with two heads; upper calf; behind knee; superficial
Origin: lateral and medial epicondyles of the femur
Insertion: calcaneous
Soleus
Location: lower calf; near ankle
Origin: proximal end of the fibula
Insertion: calcaneous
