lateral rectus extra-ocular muscle in dogs
The lateral rectus muscle is a muscle in the orbit. It is one of six extraocular muscles that control the movements of the eye (abduction in this case) and the only muscle innervated by the abducens nerve, cranial nerve VI. [WP,unvetted]. Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the lateral rectus extra-ocular muscle is
The lateral rectus muscle is a muscle in the orbit. It is one of six extraocular muscles that control the movements of the eye (abduction in this case) and the only muscle innervated by the abducens nerve, cranial nerve VI. [WP,unvetted]. The atlas records it as a muscle at the organ scale in the dog.
