Which of the following represents a joint that is highly immotile?
Fibrous
Cartilaginous
Synovial
Fibrocartilaginous
What bone is being depicted here?
Humerus
Femur
Scapula
Ulna
Explain how the muscle attached from the spine of the scapula to the olecranon of the ulna would straighten the elbow?
Muscle relaxation would extend the humeroradioulnar joint
Muscle contraction would hyperextend the glenohumeral joint and extend the humeroradioulnar joint
Muscle contraction would flex the glenohumeral joint
Muscle contraction would hyperextend the humeroradioulnar joint
Which of the following is not true of the joint pictured in the following diagram?
A joint capsule is present between the articular surfaces of each bone present
This joint is a synovial joint, with a prominent capsule present surrounding the glenoid cavity of the scapula and the head of the humerus
This joint is highly motile, allowing for rotation, circumduction, extension and flexion
This joint is also known as the glenohumeral joint
The following muscle depicted in the image is able to stabilize the forelimb laterally (prevent medial rotation), and inserts on the crest of the greater tubercle of the humerus. What muscle is this?
Supraspinatus m.
Infraspinatus m.
Triceps brachii m.
Supinator m.
What is the origin of the muscle depicted in the diagram?
Teres major tuberosity of the Humerus
Caudal border of the scapula
Proximal aspect of the humerus
Scapular notch of the scapula
What bones make up the following joint depicted?
Humerus, Radius, and Ulna
Scapula and Humerus
Humerus, Carpus, and Radius
Radius, Humerus, Olecranon
While composing of four heads, this muscle can be contracted to both flex the glenohumeral joint and extend the humeroradioulnar joint. What muscle is this?
Triceps brachii m.
Biceps brachii m.
Supraspinatus m.
Teres Major m.
What action does the following muscle have on the glenohumeral joint following contraction?
Flexion
Extension
Hyperextension
Rotation
What portion of the ulna do the triceps brachii m. insert on?
Olecranon
Ulnar tuberosity
Radial tuboeristy
Caudal border of the scapula and tricipital line of the humerus
Where does the following muscle originate from?
The supraglenoid tubercle
The crest of the greater tubercle
The greater tubercle
The infraglenoid tubercle
What action does the following muscle have if it originates from the lateral epicondyle of the humerus?
Supination
Pronation
Circumduction
Extension
The image below depicts the ___________ m., as it originates on the medial epicondyle and inserts on the dorsomedial aspect of the radius. This is also a ______ view of the forelimb.
Supinator, Cranial
Pronator teres, Caudal

Biceps brachii m., Medial
If the following muscle inserts on the proximal bones of digits II and III, what is its origin and motion?
Medial epicondyle of the humerus, flexion
Lateral epicondyle of the humerus, extension
Medial epicondyle of the humerus, extension
Lateral epicondyle of the humerus, flexion
What muscle aids in flexion, originates from the medial epicondyle and inserts on the accessory carpal bone?
Flexor carpi ulnaris m.
Extensor carpi radialis m.
Pronator teres m.
Supinator m.
What is the name of joint proximal to the the one marked in red, which can be found within the manus region?
Antebachiocarpal joint
Middle carpal joint
Inner carpal joint
Carpometacarpal joint
Flexion of the manus region would entail -?
The paw being pressed up against the caudal aspect of the ulna
The paw being pulled forward toward the cranial aspect of the radius
The paw being pulled laterally, away from the body
The paw being pulled medially, toward the body
