what is the linea alba and what is it’s literal meaning
band of connective tissue that runs from a persons sternum to pubic bone, splits abs down the middle.
means “white line”
what muscle functions in mastication
masseter and temporalis
what specific joint movements do the massester and temporalis do for the mandible
masseter- elevates the mandible
temporalis- elevates and retracts mandible
laying on back, lifting head to look at a puppy. which muscles to lift head?
sternocleidomastoid
the pectoralis major is considered to be an agonist for arm (humerus) flexion at the shoulder. what is a major antagonist for the pec. major?
deltoid and trapezius
if you need to squeeze shoulder blades together, which two muscles are used the most in this action?
rhomboid minor and major
what are the 4 rotator cuff muscles? Which ones rotate the humorus medially and laterally
supraspinatus- no rotation, elevates laterally
infraspinatus- lateral rotation
teres minor- lateral rotation
subscapularis- medial rotation
which muscles are recruited to lift up the shoulder blades
levator scapulae
the latissimus dorsi is the agonist for arm extension. which is the synergist for this muscle?
pectoralis major
the agonist for inspiration is the diaphragm. it does not help with expiration. which intercostals are the synergists and antagonists for the diaphragm?
external- synergist
internal- antagonist
list the ab muscles (sans rectus abdominus) from superficial to deep
external oblique
internal oblique
transverse abdominus
differentiate between teres major and minor
minor- rotates arm laterally
major- rotates arm medially
differentiate between pectoralis major and minor
minor acts on scapula
major acts on humorus
