What is the tuberosity of the deltoid?
Deltoid tuberosity. For other uses, see Deltoid tubercle. (Deltoideus labeled at center right.) In human anatomy, the deltoid tuberosity is a rough, triangular area on the anterolateral (front-side) surface of the middle of the humerus to which the deltoid muscle attaches.
What is the tuberosity of the humerus?
In human anatomy, the deltoid tuberosity is a rough, triangular area on the antero lateral (front-side) surface of the middle of the humerus. It is a site of attachment of deltoid muscle.
Is deltoid tuberosity serious in horses?
