which structure could you detect by placing your finger at the base of the mandible along the anterior edge of the masseter
parotid gland
the frontalis is best seen and felt by asking your partner to do what action
raise your eyebrows
to create an even more visible contraction in the sternocleidomastoid, ask your partner to flex her head after making what adjustment
rotate the head to the opposite side
which muscles are located between the SCM and the anterior flap of the trapezius
scalene
you might ask your partner to "breathe deeply into your upper chest" when palpating whihc muscle group
scalenes
passively raising the eyebrows would ----- the frontalis fibers
shorten

synergist to elevation
temporalis, masseter and medial pterygoid
to discern the posterior scalene form the levator scapula, what action could you ask your partner to perform that would contract the levator but not the scalene
elevate the scapula
located at the center of the occiput, the ___________________________ is the superior attachment site for the ligamentum nuchae
external occipital protuberance
synergists to protraction
lateral and medial pterygoid
antagonist to retraction
lateral pterygoid
not that you'd ever want tp, but passive elevation of the hyoid bone would ---- the infrahyoids
lengthen
passive protraction of the mandible would ---- the digastric
lengthen
passive protraction of the mandible would ---------- the temporalis
lengthen
passive rotation of the head and neck to the same side would ------ the sternocleidomastoid

the sternocleidomastoid, clavicle and trapezius form the _____________ of the neck
posterior triangle
what direction should you give your partner in order to locate the suprahyoid
press tongue to roof of the mouth
the brachial plexus and subclavian artery pass through a small gap between whihc two muscles on the anterior, lateral neck
scalenes and pectoralis minor
passive depression of the mandible would ------- the suprahyoid
shorten
passive elevation of the mandible would ------ the masseter
shorten
passive flexion of the head and neck would _-------- the anterior scalene
shorten
passive lateral flexion of the head and neck to the same side would ------- the sternocleidomastoid and scalene
shorten
passive rotation of the head and neck to the opposite side would ------ the scalene
shorten
