Anatomical terms of bone

The body of hyoid bone or central part of hyoid bone is of a quadrilateral form.

  • Its anterior surface is convex and directed forward and upward.
    • It is crossed in its upper half by a well-marked transverse ridge with a slight downward convexity, and in many cases a vertical median ridge divides it into two lateral halves.
    • The portion of the vertical ridge above the transverse line is present in a majority of specimens, but the lower portion is evident only in rare cases.
    • The anterior surface gives insertion to the geniohyoid muscle in the greater part of its extent both above and below the transverse ridge; a portion of the origin of the hyoglossus notches the lateral margin of the geniohyoid attachment.
    • Below the transverse ridge the mylohyoid, sternohyoid, and omohyoid are inserted.
  • The superior border is rounded, and gives attachment to the hyothyroid membrane and some aponeurotic fibers of the genioglossus.
  • The inferior border affords insertion medially to the sternohyoid and laterally to the omohyoid and occasionally a portion of the thyrohyoid. It also gives attachment to the Levator glandulae thyreoideae, when this muscle is present.
  • In early life the lateral borders are connected to the greater cornua by synchondroses; after middle life usually by bony union.
