Musdes of The four extrinsic mena dugue huolegare all w d-ntay The mus lesoftht pharynx are nece.. ryformnow ng. speakingahem chewing, swallowing, and are illustrated in the diagram below O On an anatomical model identify the muscles of the pharynx. Note that many of these muncles support the laryma by suspending it Erom the base of the skull They are organized into three groups palatini and tensor veli palatini. They elevane and tighten the soft palste during Laryngeal elevators during swallowing Styloid proces Hyoglossus Hyoid bone (cut) O The names of the extrinsic tongue muscles provide clues for identifying their attachment sites. For example, glossus refers to the tongue. The terms palato, style, genie, and hye refer to the soft palate, styloid process, mandible, and hyold bone, respectively. Use this information to identify the origins and insertions of the extrinsic tongue muscles in the table nclude the superior middle, and inferior pharyngeal They form a circular layer of muscle around the wall of the pharynx Thyrold cartlage below. Observe your lab partner while he or she is swallowing Notice that during the swallowing process, the larynx is elevated toward the pharynx. You can observe this action by dentifying the thyroid cartilage along the anterior aspect of the neck and watching it move superiorly. The act of swallowing also involves the actions of muscles that elevate the soft palate and constrict the pharynx Hyoglossus 0n a skeleton, hold appe cleaner to each muscle, origin and extend it to where the tongue would be. The various tracks of the pipe cleaners approximate the paths of the four extrinsic tongue muscles MAKING CONNECTIONS Identify at least three daily activities that require normal function of the extrinsic tongue muscles.Explanation / Answer
B.1.
Daily activities requiring function of extrinsic tongue muscle:
1. chewing
2. swallowing
3. speaking
This is possible due to the mechanical flexibility of the extrinsic muscle because of the origin and insertion points allowing for movement front,back and sideways.
