The hyoid bone (lingual bone or tongue-bone) (/ ˈ h aɪ ɔɪ d / [2] [3]) is a horseshoe-shaped bone situated in the anterior midline of the neck between the chin and the thyroid cartilage. At rest, it lies between the base of the mandible and the third cervical vertebra .
The hyoid apparatus is the collective term used in veterinary anatomy for the bones which suspend the tongue and larynx. [1] It consists of pairs of stylohyoid, thyrohyoid, epihyoid and ceratohyoid bones, and a single basihyoid bone. [2] The hyoid apparatus resembles the shape of a trapeze, [3] or a bent letter "H".

The tongue is a specialized skeletal muscle that is specially adapted for the activities of speech, chewing, developing gustatory sense (taste) and swallowing. The tongue contains two sets of muscles, the intrinsic- involved with shape of tongue, and the extrinsic- involved with tongue movement. It is attached to the hyoid bone.
The second arch becomes the hyoid and jaw support. [2] In fish, the other posterior arches contribute to the branchial skeleton, which support the gills; in tetrapods the anterior arches develop into components of the ear, tonsils, and thymus. [4] The genetic and developmental basis of pharyngeal arch development is well characterized.
The genioglossus is one of the paired extrinsic muscles of the tongue. It is a fan-shaped muscle that comprises the bulk of the body of the tongue. It arises from the mental spine of the mandible; it inserts onto the hyoid bone, and the bottom of the tongue. It is innervated by the hypoglossal nerve (cranial nerve XII). The genioglossus is the ...
In all tetrapods the cartilage partially ossifies (changes to bone) at the rear end of the jaw and becomes the articular bone, which forms part of the jaw joint in all tetrapods except mammals. [1] In some extinct mammal groups like eutriconodonts, the Meckel's cartilage still connected otherwise entirely modern ear bones to the jaw. [2]
The Biden campaign mocked Donald Trump’s mumbling and use of an “emotional support paper” to deliver a speech outside his New York hush money trial, repurposing a frequent line of attack on ...
The term “flat bone” is something of a misnomer because, although a flat bone is typically thin, it is also often curved. Examples include the cranial (skull) bones, the scapulae (shoulder blades), the sternum (breastbone), and the ribs. Flat bones serve as points of attachment for muscles and often protect internal organs.
