- Anterior belly of digastric muscleVenter anterior musculi digastriciThe anterior belly of digastric is the short front half of a two-bellied muscle, running from the inside of the chin to the hyoid.
- Anterior inferior jugular nodesNodi jugulares inferiores anterioresDeep lymph nodes of the lower neck lying in front of the internal jugular vein, below the point where omohyoid crosses it.
- Anterior longitudinal ligamentLigamentum longitudinale anteriusA long, broad band running down the front of the vertebral column, over every vertebral body and intervertebral disc.
- Ary-epiglottic part of oblique arytenoid musclePars aryepiglottica musculi arytenoidei obliquiThe ary-epiglottic part is the continuation of the oblique arytenoid muscle that runs in the ary-epiglottic fold to the epiglottis.
- Arytenoid cartilageCartilago arytenoideaA small paired, pyramid-shaped cartilage perched on the back of the cricoid, to which the vocal fold and several laryngeal muscles attach.
- Ascending part of trapezius musclePars ascendens musculi trapeziiThe ascending part is the lower, upward-slanting band of trapezius, running from the mid and lower thoracic spines to the scapular spine.
- Atlas (C1)The atlas is the first cervical vertebra, a bony ring without a body that carries the skull and lets the head nod and turn.
- Axis (C2)The axis is the second cervical vertebra, recognised by the tooth-like dens that rises from its body and acts as a pivot for the atlas.
- Cervical vertebraeVertebrae cervicalesThe cervical vertebrae are the seven small bones of the neck spine, between the skull and the thorax, each with a foramen in its transverse process.
- Corniculate cartilageCartilago corniculataA tiny cone of elastic cartilage on the tip of each arytenoid cartilage, lying in the back of the aryepiglottic fold.
- Cricoid cartilageCartilago cricoideaThe signet-ring-shaped cartilage at the base of the larynx, the only complete cartilage ring of the airway, at the level of C6.
- Cricopharyngeal ligamentLigamentum cricopharyngeumA small band at the back of the larynx that ties the lamina of the cricoid cartilage to the midline of the pharyngeal wall behind it.
- Deep cervical arteryArteria cervicalis profundaA branch of the costocervical trunk that climbs the back of the neck among the deep muscles as high as the axis.
- Dorsal scapular nerveNervus dorsalis scapulaeA slender motor nerve from the fifth cervical root that runs down the back of the neck to the rhomboids and levator scapulae.
- External part of thyro-arytenoid musclePars externa musculi thyreoarytenoideiThe external part of thyro-arytenoid is the main outer sheet of that laryngeal muscle, lying beside the vocal fold.
- Ganglia of sympathetic trunkGanglia trunci sympathiciSmall swellings strung along each sympathetic trunk beside the vertebral column, where sympathetic nerve cells relay signals to the body.
- Geniohyoid muscleMusculus geniohyoideusGeniohyoid is a narrow strap muscle in the floor of the mouth, running from the back of the chin to the hyoid bone.
- Iliocostalis colli muscleMusculus iliocostalis colliIliocostalis colli is the uppermost part of the iliocostalis column, linking the upper rib angles to the lower cervical transverse processes.
- Inferior deep lateral cervical nodesNodi cervicales laterales profundi inferioresThe lower part of the deep chain of neck lymph nodes, along the internal jugular vein below the crossing of omohyoid.
- Inferior thyroid arteryArteria thyreoidea inferior arteria thyroidea inferiorA branch of the thyrocervical trunk that loops medially behind the carotid sheath to supply the lower thyroid and the parathyroid glands.
- Internal jugular veinVena jugularis internaThe large deep vein of the neck, running in the carotid sheath from the jugular foramen down to the base of the neck.
- Interspinales colli musclesMusculi interspinales colliThe interspinales colli are short paired muscles bridging the spinous processes of neighbouring neck vertebrae, from the axis down to T1.
- Interspinous ligamentsLigamenta interspinaliaThin membranes filling the gaps between neighbouring spinous processes, from the base to the tip of each process.
- Intertransverse ligamentsLigamenta intertransversariaFibrous bands stretching between the transverse processes of neighbouring vertebrae on each side of the spine.
