So, the above-mentioned osteological features are more important to know while studying the anatomy of the dog humerus bone. Now, you will know the detailed anatomical facts of the dog humerus with the labeled diagram. Details anatomical features of dog humerus Quadratus femoris: originates on the ischium and inserts on the intertrochanteric crest. It acts to extend the hip and rotate the pelvic limb laterally. Infraspinous Fossa: A depressed area caudal to the spine. It serves as a point of attachment for infraspinatus muscle.

To make it simple, you may first learn the basic anatomy of an animal humerus bone. Then you may compare the osteological features of the dog humerus anatomy with another animal humerus. Drake, Abby Grace; Klingenberg, Christian Peter (2010). "Large‐Scale Diversification of Skull Shape in Domestic Dogs: Disparity and Modularity". The American Naturalist. 175 (3): 289–301. doi: 10.1086/650372. PMID 20095825. S2CID 26967649.The transverse process of the dog thoracic vertebrae resembles those of the horse. You will find the mammillary processes on the transverse process of the dog thoracic vertebrae. There is also an accessory process present in the last three thoracic vertebrae of the dog.

Deep digital flexor: originates on the fibular and inserts on the plantar surface of the distal phalanges. It acts to flex the digits and extend the tarsus. It is innervated by the tibial nerve. The segments and bones of the thoracic limb – scapula, humerus, radius – ulna, carpal, metacarpal, and phalanx Supraspinatus: originates on the supraspinous fossa and inserts on the greater tubercle of the humerus. It acts to extend and stabilize the shoulder joint. It is innervated by the suprascapular nerve. Subscapularis: originates on the subscapular fossa and inserts on the greater tubercle of the humerus. It acts to rotate the arm medially and stabilize the joint. It is innervated by the subscapular nerve.Do not translate text that appears unreliable or low-quality. If possible, verify the text with references provided in the foreign-language article. These are the essential osteological features of dog scapula that differs from other animal’s scapula – Deltoideus: originates on the acromial process of the scapula and inserts on the deltoid tuberosity. It acts to flex the shoulder. It is innervated by the axillary nerve.

Whilst males and females have their obvious reproductive differences, it is still incredible that within a breed they look identical. Ischiatic Arch: Caudal margin of the floor of the pelvis formed by the left and right ischiatic bones. Greater Tubercle: Large prominence located craniolateral to the head. This prominence forms a palpable feature known as the point of the shoulder on a live animal. Several shoulder muscles attach here. There is a facet (for sesamoid bone) present at the postero-lateral aspect of the distal end of each femur of the dogWhen you understand the biology of what happens you can see why trying to separate a male and female during the tie is inadvisable.
