...

Lactate is a fuel

Glucose is broken down and converted

the pectoralis minor has the potential to create neurovascular compression on which three vessels?

brachial plexus, axillary artery, and axillary vein

which muscle is a strong elbow flexor located deep to the biceps brachii?

brachialis

flexing the shoulder and pulling it anteriorly while you palpate the pectoralis major in ansidelying position has which two benefits?

brings pec major off chest wall, and allows breast tissue to fall away from the area you are palpating

can you name an everyday action in which you use your pectoralis major?

deep breathing, hug, lifting heavy stack of books, pushup

can you name one action in which the rhomboids and trapezius are antagonists?

downwardly rotate the scapula--the rhomboids do this and the traps upwardly rotate the scapula

an action to ask your partner to perform to feel the levator scapula contract is?

elevate the scapula

can you name two actions in which the rhomboids and trapezius are synergists?

elevate the scapula and adduct the scapula

to distinguish trapezius fibers from splenius capitis fibers, you could ask your partner to perform which action

extend the head or rotate head toward the side you're palpating

what is the most lateral branch of the erector spinae geoup?

iliocostalis

as a group, the transversospinalis muscles can be easily located along the __________ of the thoracic and lumbar vertebrae.

lamina groove

when contracted, splenius capitis left turns the head which direction?

left

passive extension of the elbow would ______ the brachialis

lengthen

passive pronation of the forearm would ____ the supinator

lengthen

in order to feel the tensor fascia latae contract, position your partner supine and ask him to perform what action?

medially rotate the hip

when exploring between the scapulae, can you name two muscles through which you will have to palpate to access the deeper erector spinae fibers?

middle trapezius and rhomboids

the _______ muscle is an antagonist to both the biceps brachii and supinator

pronator teres

to contract the lower fibers of the erector spinae group in a prone position, you could ask your partner to perform what action?

raise and lower the feet

the serratus anterior abducts the scapula, making it a direct antagonist to the?

rhomboids

unlike the long vertical erector fibers, the branchs of the transversospinalis group consist of many _______ fibers

short, diagonal

passive pronation of the forearm would _____ the pronator teres.

shorten

what action could you ask your partner to perform to confirm that you have located psoas major?

slightly flex the hip

what is the most medial branch of the erector spinae group?

spinalis

what two bony landmarks and one region can be helpful to isolate the location of the suboccipitals?

spinous process of C2, transverse process of C1, and the superior nuchal line of the occiput

in the lumbar region the erectors lie deep to what connective tissue structure?

thoracolumbar aponeurosis

the splenius capitis is a deep muscle except on the lateral side of the neck where it is superficial between which two muscles?

trapezius and SCM

how can the upper fibers of the trapezius be helpful in locating suboccipitals?

you must palpate through the upper trapezius to feel the suboccipitals and the lateral edge of the traps is the same width as the suboccipitals

Muscle cramps caused by muscle receptors that are over fatigued

...

passive flexion of the elbow would _____ the brachioradialis

shorten
