The styloid process projects from the inferior part of the petrous temporal bone and offers attachment to the stylohyoid ligament and the stylohyoid, stylopharyngeus, and styloglossus muscles. Through these structures, the styloid …The hyoid apparatus helps to support the larynx and several tongue muscles. In EQUINE the basihyoid, the central bone of the hyoid apparatus, has a prominent lingual process (Fig. 4.8/5) that is embedded in the root of the tongue. The thyrohyoids project caudodorsally from the basihyoid and articulate with the thyroid cartilage of the larynx. Only one known complete hyoid bone exists from a Neanderthal: from a specimen known as Kebara 1 from a cave in Israel of the same name. ... So, Neanderthals had the anatomical properties to create the sounds that could form the basis of speech, though any words they produced would have sounded a bit unfamiliar to modern human …Endotracheal intubation is an essential skill performed by multiple medical specialists to secure a patient’s airway as well as provide oxygenation and ventilation.

The suprahyoid region extends from the base of the skull to the hyoid bone and includes the pharyngeal, parapharyngeal, parotid, carotid, masticator, retropharyngeal, and perivertebral spaces, as well as the oral cavity. The areas that can be explored by ultrasound include the parotid, carotid, and masticator spaces; the oral ...The hyoid bone is made of a body, two greater horns, and the two lesser horns: identified as its body.
