QuestionAnswer
originates chiefly from the C4 nerve root (but receives contributions from C3 and C5. innervates the diaphragm.
motor innevation of tensor veli palatini
inferior border of the posterior cervical triangle
muscle that opens the pharyngeal orifice of the eustachian tube during swallowing

the roots of the brachial plexus appear between which 2 muscles?
inferior thyroid artery arises from
the point of entry to the venous system for central line placement to administer parenteral (nutritional) fluids and medications and to measure central venous pressure.
the submental, submandibular, the carotid, and the muscular triangles make up the ____ ____ _____?
triangle Bounded by anterior border of SCM, superior belly of omohyoid, midline of neck
which muscle divides the neck into anterior and posterior triangles?
the thyrocervical trunk comes from which artery?
which artery crosses the recurrent (inferior) laryngeal nerve?
motor innervation of the sternocleidomastoid
innervation of the sternothyroid
the superior and middle thyroid veins drain into what?
an incomplete circular band of lymphoid tissues around the superior pharynx
the occipital artery comes from which main artery?
posterior border of the posterior cervical triangle
this layer of the deep cervical fascia forms a sheath around the vertebra and it's surrounding muscles
which tonsils lie in the tonsillar fossa?
which nerve passes through the occipital triangle?
innervation of the splenius capitis
an emergency procedure where a cut or passageway is made in the cricothyroid membrane.
triangle bounded by anterior belly of omohyoid, posterior belly of digastric, and anterior border of SCM
innervation of stylohyoid muscle
what attaches to the pharyngeal tubercle?
True or False: the stylopharyngeus, salpingopharyngeus, and palatopharyngeus serve to shorten and widen pharynx during swallowing and speaking.
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
provides motor innervation to Cricothyroid muscle
sinus between the palatoglossal and palatopharyngeal arches
(from C2 and C3 roots) supplies the skin covering the anterior cervical region
Bifurcation of common carotid artery into external and internal carotid arteries occurs at what cervical vertebra level?
Anterior boundary of the anterior cervical triangle
QuestionAnswer
what muscle is the landmark for the division of the subclavian arteries
innervation of the middle scalene (roots?)
supplies blood to the inferior part of the thyroid gland
innervation of stylopharyngeus
provides motor innervation to most of the muscles of the tongue
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
motor innervation of middle constrictor muscle and inferior constrictor muscles
the sternal head of the sternocleidomastoid attaches to what?
Superior boundary of the anterior cervical triangle
Thin, broad sheet of muscle within superficial fascia of the neck that is used in facial expression
nerve is located in the tracheo-esophageal groove.
nerve that supplies the skin of the neck and scalp posteriosuperior to the auricle. Comes from C2
nose opens into the nasopharynx via what structures?
motor innervation of superior constrictor muscle
hyoid bone lies at the level of which vertebra
innervation of the thryohyoid
innervation of the posterior scalene (roots?)
the roots of C1-C4 make up the _____?
a rib which arises from the seventh cervical vertebrae (above the normal first rib).
anterior border of the posterior cervical triangle
triangle located between Between body of hyoid bone and right and left anterior bellies of the digastric muscles
portion of the pharynx that is posterior to the nose and superior to the soft palate
2nd portion of the subclavian artery
innervation anterior belly of digastric muscle
(from C2 and C3 roots) ascends superiorly across SCM. Supplies the skin over parotid, posterior auricle, and skin from mandible to mastoid process
innervation of the longus colli
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
origin of the salpingopharyngeus
enlargement of the thyroid gland
surgical removal of the thyroid gland
innervation of the longus capitis
what lies posterior to the transverse cervical artery and suprascapular artery as they cross the anterior surface of the scalenus anterior muscle.
the largest and most clinically important fascial interspace of the neck because it is the major pathway for the spread of infection
fascia with common carotid artery, internal jugular vein, and vagus nerve
QuestionAnswer
which muscle of the pharynx attaches along the oblique line of the thyroid cartilage and on the cricoid cartilage laterally

first branch of subclavian artery
motor innervation of the palatopharyngeus
sensory innervation of the sternocleidomastoid
fascia of the neck prevents the spread of what?
roof of posterior cervical triangle
digestive organ that directs food to the esophagus.
Head bends to affected side and face turns away.Facial asymmetry can occur, because of growth retardation on affected side.
