The mechanism by which these fish capture prey involves upper jaw protrusion, lower jaw depression, hyoid depression, and cranial rotation. |
|
The hypohyal is a ventral element of the hyoid arch which links the ceratohyal and the basihyal. |
|
Again, we see that the mandibular and hyoid arches are developmentally different from the rest of the series. |
|
The muscles joining the hyoid bone to the jaw should be relaxed so that the larynx is pulled forward and upwards. |
|
Those muscles below the mandible are anatomically described as being above or below the hyoid bone. |
|
Physical examination revealed a golf-ball-sized lesion fixed to the hyoid bone in the anterior midline of the neck. |
|
The hyoid bone, thyroid cartilage, and cricoid cartilages are located within the central portion of the neck. |
|
The tongue is suspended from the inside of the mandible above the hyoid bone and has muscles with a range of different orientations. |
|
The specimen had an intact hyoid bone, located at the back of the tongue, which is where the voice box hangs. |
|
In most vertebrates the hyoid supports the tongue, as it does in the snake-necked turtle. |
|
Geese, of course, do not rely on this tongue for getting food into the mouth, so the hyoid apparatus tends to be simple, but powerful. |
|
The greater horn of the hyoid may be joined to the body of the hyoid by an articulation. |
|
The upper horns meet the back of the hyoid bone, while the inferior cornua are attached to the side of the cricoid, forming a pivotal joint. |
|
The anteromeclial process for articulation with the hyoid body is wide, flattened, and mildly concave on its dorsal face. |
|
It may be long, terminating below the level of the thyroid cartilage, or short, terminating at the level of the hyoid bone. |
|
Due to the reduction of the hyoid and branchial arches, no other means than the suction flow seems to be available for this function. |
|
The insertion of the superior belly may overshoot the hyoid bone and attach alongside the digastric. |
|
Lateral expansion occurs through rotation of the curved ceratobranchials I and 2 about their articulations with the hyoid body. |
|
These are formed from fused hyoid rays and articulate with the succeeding gill arches. |
|
The cystic lesion and an adjacent portion of hyoid bone were surgically excised. |
|
|
The chimaeran hyoid is, it turns out, quite happy supporting the operculum and has no interest in the palatoquadrate. |
|
I included all muscles associated with the jaws, tongue and hyoid, palate, and pharynx. |
|
Freeing the tongue from the hyoid removes a limit on tongue excursion imposed by the basic architecture of the mammalian feeding apparatus. |
|
Speech requires flexibility of the upper airway, including laryngeal and hyoid mobility and separation of the hard palate from the epiglottis. |
|
Ectoderm from the mesencephalon and rhombomere specifically migrates to the mandibular arch primordium, and rhombomere infiltrates the hyoid arch. |
|
Fibres of the hypobranchial muscles in the region of the hyoid are utilized to form the internal musculature of the tongue. |
|
Their contraction shortens the tongue towards its base on the hyoid. |
|
The hyoid bones, except for the stylohyal, are left and the tip of the epiglottis is removed. |
|
They were endowed with a hyoid bone, which anchors the tongue and allows a wide variety of movements of the larynx. |
|
Elephants have only five bones in the hyoid apparatus, and the gap formed by the missing bones is filled by muscles, tendons, and ligaments. |
|
The superficial constrictor of the hyoid arch in sharks is remodeled in bony fishes to control the opening and closing of this protective cover. |
|
Tongue swiss cut is the part of the tongue that remains after all of the hyoid bones and most of the attached fat are removed. |
|
The surgical technique must remove the hyoid bone in monobloc while going up until the contact of the base of the tongue. |
|
The upper airway may also appear to be normal beneath intact mucosal, despite hyoid bone or laryngeal fractures. |
|
There may be an obvious opening in the anterior neck between the hyoid bone and suprasternal notch. |
|
Infrahyoide muscles dissection from the posterior-inferior surface of the hyoid bone body. |
|
Reposition of the hyoid bone and suprahyoid muscles in place, and suture of infrahyiod muscles to hyoid bone. |
|
The thyroid cartilage and epiglottis are connected to the hyoid bone, and the cricoid cartilage is connected to the trachea by the extrinsic ligaments of the larynx. |
|
Such a mechanism would have been analogous to expansion of the buccal and gular cavities of fishes and many tetrapods by the hyobranchial muscles acting on the hyoid arches. |
|
The authors prove the importance of the mandible, that constitutes the mandibular system between the tongue and the hyoid bone, as both function with the skull as a pump that suctions the cephalic rachidial liquid. |
|
|
The hyoid bone was carefully released from the suprahyoid tongue base muscles. |
|
Discussed in this article as part of the axial skeleton is a third subdivision, the visceral, comprising the lower jaw, some elements of the upper jaw, and the branchial arches, including the hyoid bone. |
|
Hyoid suspension surgery is less invasive than the more widely used genioglossus advancement with hyoid myotomy. |
|
Tetrapods, with the exception of mammals, utilize part of the constrictor muscle of the hyoid arch to form the depressor mandibulae, which replaces the hypobranchial muscles as the major jaw-opening muscle. |
|
The chameleon tongue apparatus consists of highly modified hyoid bones, tongue muscles, and collagenous elements. |
|
In the vast majority of mammals, the throat contains nine bones connected in a boxlike structure, the hyoid apparatus, that supports the tongue and the voice box. |
|
Skeletal elements of the chondrocranium were simplistic and dominated by the hyoid, hyomandibulosymplectic cartilage, ethmoid and Meckel's cartilage in first feeding larvae. |
|
A thyroglossal duct was located, traced superiorly, and removed together with a 1-cm midline portion of the hyoid bone. |
|
Where laryngeal elevation is a problem, neuromuscular stimulation or muscle strengthening of the hyoid musculature offers hope. |
|
Rather than speaking about thyroglossal anomalies, the authors propose to call them hyo-glossal anomalies because these lesions are always involving the hyoid bone. |
|
Worldwide, hyoid suspension surgery is usually performed along with genioglossus advancement or maxillomandibular osteotomy. |
|
The changes in swallow physiology were assessed based on the hyoid movement and the penetration-aspiration scores during swallow of a thin liquid. |
|
The skeleton of most snakes consists solely of the skull, hyoid, vertebral column, and ribs, though henophidian snakes retain vestiges of the pelvis and rear limbs. |
|
The incidences of cervical rib, asymmetrically shaped sternebra, and incomplete ossification of hyoid bone, were significant in all treatment groups. |
|
Her sacrum had a right lateral torsion and fascial tension radiated from her respiratory diaphragm anteriorly into her neck, with her hyoid bone deviated to the right. |
|
The research team discovered that the connection between the larynx and the ear via the stylohyal bone in the hyoid chain was unique to bats that used laryngeal echolocation. |
|
The hyoid myotomy operation involves moving the hyoid bone forward, detaching the muscles and fixating the hyoid bone to the thyroid cartilage with non-resorbable sutures. |
|
The branchial horn I is curved dorsomedially and is longer than branchial horn II, which is the only element of the hyoid apparatus that ossifies. |
|
Postcranial pneumaticity is absent in all other extant vertebrates with the known exceptions of osteoglossomorph fish and the hyoid bone in howler monkeys. |
|
The ligamentous part of that apparatus originates in the ceratohyal cartilage and extends from the stylohyoid to the lesser cornu of the hyoid bone. |
|
|
Ceratohyal and epihyal cartilages continually expand until 9 DPH when the hyoid reaches its maximum depth and has the full complement of six branchiostegal rays. |
|
Surgical exploration and removal of the mass was done, but because the hyoid apparatus was incorporated in the base of the cyst, complete surgical excision was not possible. |
|
Peak opening of the jaw, depression of the hyoid bone, protrusion of the premaxilla, lateral movement of the head, and buccal velocity were measured. |
