When this muscle contracts, thetongue must behave in a manner already described, andquoted from the authority above. 27. The cerato-glossus is a small muscle we find onthe upper side of the hyoid, one on either cornua. Eachoccupies, as an origin, the half of the surface of the firstbasibranchial. After passing over the joint formed bythe head of the thyro-hyal, the fibres become moretendinous, as they insert themselves along the upperside of the shaft of the cerato-branchial element. They.
