The infrahyoid muscles, or strap muscles, are a group of four pairs of muscles in the anterior (frontal) part of the neck. [1] The four infrahyoid muscles are the sternohyoid, sternothyroid, thyrohyoid and omohyoid muscles.
It is then seen supplying a dog's head with oxygenated blood. The head is presented with external stimuli, which it responds to.

A dog can identify a sound's location much faster than a human can, as well as hear sounds at four times the distance. [41] Dogs can lose their hearing from age or an ear infection. [42]
Sternohyoid, omohyoid, sternothyroid are supplied by ansa cervicalis. Thyrohyoid: by a branch of hypoglossal nerve but the fibres are all 'hitch-hiking' from C1.
