Q

list the infrahyoid muscles that attach to the hyoid bone. What is the destination from the hyoid?

A

infra hyoid uscles ( the strap muscles)

  1. located in muscular compartment
  2. 3 of them attache to the hyoid bone
  3. a superficial layer of two parallel muscles
    1. STERNOHYOID
      1. medially attaches to manubrium of sternum
    2. OMOHYOID (omo =shoulder)
      1. superior belly, laterally
      2. joins the inferior belly by an intermediate tendon/attache to scapula
