Cards

Term
supraspinatus
Definition
lies beneath the acromiotrapezius and occupies the supra-spinous fossa of the shoulder blade; one of the rotator cuff muscles
Movement: helps abduct arm
Term
infraspinatus
Definition
occupies the infraspinous fossa of the shoulder blade; one of the rotator cuff muscles
Movement: helps rotate the humerus outward
Term
subscapularis
Definition
occupies the subscapular fossa; one of the rotator cuff muscles
Movement: helps to medially rotate the humerus
Term
teres major
Definition
below infraspinatus muscle along caudal border of the scapula
Movement: rotates the humerus medially and retracts the arm
Term
rhomboideus
Definition
seen between the two shoulder blades when the latter are spread appart; it is subdivided into several bundles
Movement: draws the scapula toward the vertebrae; assists in adduction of arm
Term
serratus ventralis (anterior)
Definition
fan-shaped muscle seen between the shoulder blade and body wall
Movement: protracts the scapula and assists in abduction of the arm
Term
sartorius
Definition
wide, thin muscle seen primarily on the anterior half of the inner surface of the thigh
Movement: flexes and abducts the thigh at the hip joint; flexes the knee to some extent
Term
tensor fascia latae
Definition
triangular muscle adjacent to the lateral Dart of the sartorius; the fascia lata continues from this muscle down to the shank of the leg
Movement: flex and abduct the thigh at the hip joint
Term
gracilis
Definition
muscle covering the medial surface of the thigh caudal to the quadriceps complex and the sartorius
Movement: adducts the leg and flexes the knee when contracting
Term
biceps femoris
Definition
large muscle caudal to the fascia lata; bounds the lateral wall of the popliteal fossa
Movement: flex the knee and contract the leg at the hip joint
Term
semitemdinosus
Definition
long cylindrical muscle which forms the medial wall of the popliteal fossa
Movement: helps flex the shank; retracts the leg at the hip joint
Term
semimembranosus
Definition
large, thick muscle beneath the gracilis; divided into 2 parts in the cat
Movement: retracts teh thigh and flexes the shank
Term
caudalfemoralis
Definition
small muscle just cranial to and dorsal to the biceps femoris near the base of the tail; only in cat
Movement: helps in abduction of the thigh and retraction of the leg in the cat
Term
gluteus maximus (gluteus superficialis)
Definition
muscle just cranial to the caudofemoralis in the cat; it is more developed in the human than the cat
Movement: helps in the abduction of the thigh and the retraction of the leg
Term
gluteus medius
Definition
muscle just cranial to and partially under the gluteus maximus; also covered by a portion of the tensor fascia lata muscle; more developed in cats than humans
Movement: helps in abduction of thigh
Term
vastus lateralis
Definition
muscle under the sartorius and fascia lata on the lateral aspect of the thigh
Movement: extends the leg at the knee joint via patellar tendon/ligament
Term
vastus medialis
Definition
muscle under the sartorius on the medial aspect of the thigh
Movement: extends the leg at the knee joint via patellar tendon/ligament
Term
rectus femoris
Definition
long, rounded muscle seen between the vastus lateralis and vastus medialis
Movement: extends the leg at the knee joint vial patellar tendon/ligament
Term
vastus intermedius
Definition
cannot be seen superficially; fourth muscle of the quadriceps femoris complex
Movement: extends the leg at the knee joint via patellar tendon/ligament
