Why is the deltoideus not divided into two parts in the horse?
Because the horse lacks an acromion therefore, no acromial and scapular parts of the deltoideus.
What is the glenohumeral joint common name?
Shoulder joint
What extends from the greater to the lesser tubercle over the inter tubercular groove of the humerus holding the tendon of the biceps brachii in place?

True/False: In the cat, there is an additional supracondylar foramen near the medial aspect of the condyle through which the brachial artery and median nerve pass
True
What is known as the “knee” by horse owners?
Carpus: comprised of 7-8 carpal bones located within two rows, none which are fused. Carpal bone 1 is absent in about 80%-85% of horses.

Intermediate tubercle
Identify the highlighted structure on the pelvic limb:
