Section 1

Question Answer
Wolff's Lawbones form in areas of stress and reabsorb in areas of nonstress
5 golden rules of muscles1) at least one origin and insertion, 2) insertion moves towards origin during contraction, 3) bulk of muscle lies proximal to joint it crosses, 4) muscles can only contract (stretch antagonist), 5) origin least movable (usually proximal) and insertion more movable usually distal)
only neck muscle that moves scapulaLevator scapula
3 muscles attach to corocoid process of scapulaCorocobrachialis, Pectoralis minor, Biceps brachii (short head)
Claviclefirst bone to form in babies, last to finish in adolescence, most easily broken bone
Deltoid antagonist to itself howflexion/extension, medial/lateral rotation, and horizontal abduction/adduction of shoulder
Deltoid and Trapezius share what attachment pointLateral one-third of clavicle, acromion, and spine of scapula (Delt origin and Trap insertion)
Trapezium antagonist to itself howelevation/depression of scapula
Swimming musclesLatissimus dorsi and Pronator teres and quadratus
Muscles share handcuff motion actionsLatissimus dorsi and Teres major (extension, adduction, and medial rotation of shoulder)
most easily torn rotator cuff muscle (especially in baseball)Supraspinatus
only rotator cuff muscle to insert on lesser tubercle of humerusSubscapularis
rotator cuff muscles that share lateral rotation and adduction of shoulder actionsInfraspinatus and Teres minor
Pectoralis major antagonist to itself howflexion/extension of shoulder
brachial plexus runs deep to what musclePectoralis minor
Thoracic Outlet Syndrome compression of whatBrachial Plexus (median, msuculocutaneous, radial, ulnar, axillary nerves)
nerve involved in carpal tunnelmedian
nerve for hit elbowulnar
chunk of muscle at thumb and pinkie basethenar and hypothenar eminence
tennis elbowlateral epicondyle of the humerus
muscle divides front and back of arm, used in hammer curlBrachioradialis
head of ulna and radiusulna at wrist, radius at elbow, styloid process of radius at wrist
golf elbowmedial epicondyle of the humerus
elbow nameolecranon
pops up during wrist flexionlunate
anatomical snuffboxscaphoid
pinkie side chopping motionpisiform
strongest elbow flexerBrachialis
tendon pops when making fistPalmaris longus
pronation stronger than supination because2 muscles vs 1
only bone that doesn't articulate directly with another boneHyoid bone
Sternocleidomastoid and Scalenes share what actionslateral flexion and rotation of head and neck (all same side except scalenes when rotating)

Section 2

Question Answer
carpal bonesscaphoid, lunate, triquetrum, pisiform, trapezium, trapezoid, capitate, hamate
insertion site for Flexor carpi radialisbase of 2nd and 3rd metacarpals
most commonly torn rotator cuff muscleSupraspinatus
insertion site for Subscapularislesser tubercle of humerus
origin and insertion for supraspinatusO: Supraspinatus fossa of scapula, I: greater tubercle of humerus
actions of rhomboidsadduction, elevation, and downward rotation of scapula
specific term used to describe entrapment of brachial plexusTOS - Thoracic Outlet Syndrome
tarsal bonescalcaneus, talus, navicular, cuboid, lateral and intermediate and medial cuneiform
what cervical vertebrae does the levator scapula attach toC1-C4
what 3 ribs does pectoralis minor originate on3-5
nerve compressed with carpal tunnelmedian
nerve causes numbness in pinkyulnar
nerve innervates subclaviussubclavian
nerve innervates biceps brachiimusculocutaneous
5 nerves of brachial plexusradial, median, ulnar, axillary, musculocutaneous
structure deep to pectoralis minorbrachial plexus
4 tendons that insert on lateral epicondyleExtensor carpi radialis longus and brevis, Extensor digitorum, and Extensor carpi ulnaris
5 flexors on medial epicondyleFlexor carpi ulnaris, Flexor carpi radialis, Palmaris longus, Flexor digitorum superficialis and profundus
origin of serratus anteriorupper 8 or 9 ribs
4 bones the SCE attaches tosternum, clavicle, occiput, temporal
3 actions of Extensor carpi radialis longus and brevisextension and abduction of wrist, and flexion of elbow
2 actions of abductor digiti minimi and Flexor digiti minimiopposition, flexion, abduction
ribs scalenes insert onanterior and middle on 1st, posterior on 2nd
brachialis insert onulna
insertions of biceps brachiituberosity of the radius and aponeurosis of biceps brachii
insertion of tricpes brachiiolecranon process
3 actions of triceps brachiiextend elbow, and extend and adduct shoulder
coracobrachialis inserts onhumerus
levator scapula rotates head to which sidesame
