masseter

synergist to rotation

middle scalene, multifidi, and trapezius

which muscle runs form the hyoid bone to the superior border of the scapula and is mostly inaccessible

to access the insertion of the temporalis, you must ask your partner to perform what action

open the mouth wide

the ______________ bones merge at the body's midline to form the sagittal suture

parietal

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

tightening the fascia of the neck would ------ the platysma

shorten

synergist to extension

splenius capitis and cervics

antagonist of extension

sternocleidomastoid

the anterior scalene lies partially deep to the lateral edge of whihc muscle

sternocleidomastoid

antagonist to protraction

temporalis and digastric

synergist to retraction

temporalis and digastric

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

lengthen

antagonist to flexion

which scalene is difficult to distinguish form surrounding muscle bellies

posterior scalene

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

what three landmark create the borders of the neck's anterior triangle?

sternocleidomastoid, base of the mandible, and trachea

the two heads of the SCM originate at the ________ and the _______
