Anatomy I- Canine Pelvic Limb Muscle Actions Flashcards
Sartorius (Cranial Head)
Extends Stifle, flexes hip
Sartorius (Caudal Head)
Flexes Stifle, Flexes hip
Superficial Gluteal
Extends hip, Abducts the limb
Middle Gluteal
Extends hip, Abducts the limb
Deep Gluteal
Extends hip, Abducts the limb
Tensor Fascia Latae
Flexes hip, Extends Stifle, Abducts the limb
Semitendinosus
Extends hip, Flexes Stifle, Extends Tarsus
Semimembranosus (Cranial Head)
Extends Stifle
Semimembranosus (Caudal Head)
Flexes Stifle
Biceps Femoris
Extends hip, flexes and extends stifle, extends tarsus, abducts limb.
Piriformis
Extends hip, flexes stifle
Internal Obturator
Laterally rotates femur
Caudal Crural Abductor
abducts limb, flexes stifle ( helps with leg lifting for urination)
Gemelli
Laterally rotates femur
Quadratus Femoris
Extends hip, Laterally rotates femur
Quadriceps Femoris ( Which are the 4 parts)
Vastus Lateralis (most lateral aspect), Vastus Medialis (most Medial aspect), Vastus Intermedius (closest to femur (bottom of bun), Rectus Femoris (in between medialis and lateralis ( hot dog in bun))
Quadriceps Femoris
Extends Stifle (Rectus Femoris flexes hip as well)
External Obturator
Laterally Rotates Femur
Pectineus
Adducts limb
Adductors
Two heads: Magnus et longus and Magnus et brevis - Both adducts limb, extends hip
Cranial Tibial
flexes tarsus, supinates pes
Fibularis longus
flexes tarsus, pronates pes
Long digital Extensor
extends digits, flexes tarsus
Gastrocenemius
extends tarsus, flexes stifle ( medial and lateral heads) same action both heads.
Deep digital flexor
lateral head and medial head ( medial head much smaller than lateral head ) Flexes digits, extends tarsus
Superficial Digital flexor
flexes stifle, extends tarsus, flexes digits
Popliteus
pronation
Gracilis
adducts limb, flexes stifle, extends tarsus
