Quiz 11
brachiocephalicus
Identify the muscle shown in the picture. This is the __________________ muscle.
subscapularis
Identify this muscle on the medial aspect of the scapula.
omotransversarius
The superficial cervical lymph nodes lie just deep to this muscle. This picture is of the left lateral thoracic limb. This is the __________________ muscle.
latissimus dorsi
This large muscle draws the limb caudally and flexes the shoulder joint. Name this muscle.
omotransversarius
This muscle (pin 11) originates on the wing of the atlas and inserts on the spine of the scapula. This is the _________________ muscle.
deep pectoral
This muscle adducts the limb AND pulls it caudally. Name this muscle.
superficial pectoralis
This muscle has a descending and a transverse portion, which both insert on the humerus. Name this muscle.
rhomboideus
This muscle has three parts, the capital, cervical, and thoracic. Each part inserts on the dorsal border of the scapula. Name the muscle identified by 11 and 12 in the picture.
brachiocephalicus
This muscle has three parts. When the animal is walking this muscle helps to advance the thoracic limb and extend the shoulder. This is the ________________ muscle.
rhomboideus
This muscle lies deep to the trapezius and works with the trapezius to elevate the thoracic limb. Name this muscle. Identify the muscle indicated by number 12.
supraspinatus
This muscle lies on the lateral aspect of the scapula, deep to the trapezius. Name this muscle.
deep pectoral
This muscle originates along the length of the sternum and inserts on the humerus. Name this muscle.
latissimus dorsi
This muscle originates from the caudal thoracic and lumbar vertebrae and inserts on the humerus. Name this muscle.
brachiocephalicus
This muscle originates on the clavicle or clavicular intersection. This is the ________________ muscle.
Superficial pectoralis
This muscle originates on the cranial sternum and adducts the thoracic limb. Name this muscle.
serratus ventralis
This picture is of a cat in dorsal recumbency with the head to the left and the orange arrow pointing to the right side of the body. This muscle acts as a sling to support the trunk. Name this muscle indicated by the orange arrow.
serratus ventralis
This picture is of a cat in dorsal recumbency with the left thoracic limb lifted out of the way. This muscle acts as a sling to support the scapula. Identify the muscle shown in the picture indicated by the orange arrow.
trapezius
This picture is of the left lateral dorsal view of the thoracic limb. This muscle that inserts on the spine of the scapula acts to elevate and abduct the thoracic limb. Name this muscle.
trapezius
This picture is of the left lateral dorsal view of the thoracic limb. This triangular-shaped muscle has both cervical and thoracic parts This muscle lies over the dorsal part of the scapula. Name this muscle.
lateral head of triceps brachii
This picture is of the left lateral thoracic limb. (The cat's head would be toward the left in the picture.) The picture indicates one head of this muscle on the caudal aspect of the humerus. Name this muscle.
long head of triceps brachii
This picture is of the left lateral thoracic limb. (The cat's head would be toward the left in the picture.) The picture indicates one head of this muscle on the caudal aspect of the humerus. Name this muscle.
brachialis
This picture is of the left lateral thoracic limb. (The cat's head would be toward the upper part of the picture.) This muscle acts to rotate the brachium. Identify this muscle.
deltoid
This picture is of the left lateral thoracic limb. This muscle has 2 parts. Name this muscle.
infraspinatus
This picture is of the left lateral thoracic limb. This muscle lies deep to the deltoideus. Name this muscle.
teres major
This picture is of the left lateral thoracic limb. This muscle on the caudal aspect of the shoulder helps to flex the shoulder.
biceps brachii
This picture is of the left medial aspect of the thoracic limb. (The cat's head would be to the right.) This muscle lies on the craniomedial aspect of the humerus.
