QuestionAnswer
motor innervation of superior constrictor muscle
provides sensory innervation above vocal folds
portion of the pharynx that is posterior to the nose and superior to the soft palate
an emergency procedure where a cut or passageway is made in the cricothyroid membrane.
which muscle divides the neck into anterior and posterior triangles?
which artery crosses the recurrent (inferior) laryngeal nerve?
what lies posterior to the transverse cervical artery and suprascapular artery as they cross the anterior surface of the scalenus anterior muscle.
triangle located between Between body of hyoid bone and right and left anterior bellies of the digastric muscles
innervation of the middle scalene (roots?)
True or False: the stylopharyngeus, salpingopharyngeus, and palatopharyngeus serve to shorten and widen pharynx during swallowing and speaking.
innervation of the thryohyoid
(from C2 and C3 roots) supplies the skin covering the anterior cervical region
this area of deep cervical fascia is limited to the anterior portion of the neck and it contains a muscular portion (surrounds infrahyoid muscles) and a vascular portion ( surround
Superior boundary of the anterior cervical triangle
(from C2 and C3 roots) ascends superiorly across SCM. Supplies the skin over parotid, posterior auricle, and skin from mandible to mastoid process
triangle bounded by anterior belly of omohyoid, posterior belly of digastric, and anterior border of SCM
muscle that opens the pharyngeal orifice of the eustachian tube during swallowing
origin of the salpingopharyngeus
nose opens into the nasopharynx via what structures?
innervation of the sternohyoid
which tonsils lie in the tonsillar fossa?
what muscle is the landmark for the division of the subclavian arteries
innervation of the omohyoid
the sternocleidomastiod and the trapezius muscle are surrounded by this layer of the deep fascia of the neck
fascia of the neck prevents the spread of what?
the roots of the brachial plexus appear between which 2 muscles?
the posterior cervical triangle is subdivided by which muscle?
triangle Bounded by anterior border of SCM, superior belly of omohyoid, midline of neck
an incomplete circular band of lymphoid tissues around the superior pharynx
anterior border of the posterior cervical triangle
the roots of C1-C4 make up the _____?
innervation anterior belly of digastric muscle
a rib which arises from the seventh cervical vertebrae (above the normal first rib).
the surgical creation of an artificial airway in the trachea (windpipe) on the anterior surface of the neck.
QuestionAnswer
junction between the thorax and the neck is known as the
the largest and most clinically important fascial interspace of the neck because it is the major pathway for the spread of infection
motor innervation of middle constrictor muscle and inferior constrictor muscles
inferior border of the posterior cervical triangle
innervation of stylopharyngeus
innervation of the posterior scalene (roots?)
hyoid bone lies at the level of which vertebra
provides motor innervation to most of the muscles of the tongue
motor innervation of the salpingopharyngeus
innervation of the splenius capitis
innervation of the longus colli

the right recurrent laryngeal nerve loops behind which structure?
which muscle of the pharynx attaches along the oblique line of the thyroid cartilage and on the cricoid cartilage laterally
2nd portion of the subclavian artery
Thin, broad sheet of muscle within superficial fascia of the neck that is used in facial expression
this portion of the pharynx is bounded by the soft palate superiorly, the base of the tongue inferiorly and the platoglossal and platopharyngeal arches laterally
which nerve passes through the occipital triangle?
the superior laryngeal nerve is a branch from which nerve
arises from the C3 and C4 nerve roots and passes under the cover of the SCM and sends small branches to the skin of the neck and across the clavicle to supply skin over shoulder
the thyrocervical trunk comes from which artery?
three layers of deep fascia in the neck
inferior thyroid artery arises from
the sternal head of the sternocleidomastoid attaches to what?
inferior thyroid vein drains into
nerve that supplies the skin of the neck and scalp posteriosuperior to the auricle. Comes from C2
The laryngeal prominence, larger in males, is located at which vertebra level?
nerve is located in the tracheo-esophageal groove.
small depression of the laryngealpharyngeal cavity on each side of inlet
triangle located between inferior mandible and anterior and posterior bellies of the digastric muscle
innervation of the anterior scalene (roots?)
enlargement of the thyroid gland
This lobe is an embryological remnant of the thyroglossal duct
supplies blood to the inferior part of the thyroid gland
QuestionAnswer
originates chiefly from the C4 nerve root (but receives contributions from C3 and C5. innervates the diaphragm.
the occipital artery comes from which main artery?
innervation of the sternothyroid
the external jugular vein, suprascapular artery, and subclavian artery are contained in which portion of the posterior cervical triangle?
innervation of stylohyoid muscle
first branch of subclavian artery

roof of posterior cervical triangle
posterior border of the posterior cervical triangle
attachment of the middle constrictor muscle of the pharynx?
surgical removal of the thyroid gland
sinus between the palatoglossal and palatopharyngeal arches
digestive organ that directs food to the esophagus.
Lateral boundary of the anterior cervical triangle
what attaches to the pharyngeal tubercle?
Head bends to affected side and face turns away.Facial asymmetry can occur, because of growth retardation on affected side.
