=== '''Infrahyoid     strap muscles''' -     function of swallowing, depressing larynx; depressing hyoid. Nerve supply     via ansa cervicales, often dual innervation above level of lower border of     thyroid cartilage and also at level of suprasternal notch - so divide     midway between lower border of thyroid cartilage and suprasternal notch. ===

** '''Sternohyoid'''
*** Originates from back of       manubrium; ascends to body of hyoid
** '''Omohyoid'''
*** Inserts immediately lateral       sternohyoid on hyoid bone; passes downwards to an intermediate tendon       behind SCM (held in position by a condensation of cervical fascia       attaching it to clavicle); then passes obliquely to upper border of       scapula, near scapula notch
** '''Sternothyroid'''
*** Arises from back of       manubrium inferior to origin of sternohyoid; passes upwards; inserts on       thyroid cartilage
** '''Thyrohyoid'''
*** Direct extension of       sternothyroid
*** Arises from line of       insertion of sternothyroid; inserts to body and greater cornu of hyoid
