| Question | Answer |
|---|---|
| Where does the trapezius muscle insert itself? | Clavicle and scpaulae |
| The major abductor | Deltoid |
| Synergist of the deltoid muscle | Supraspinatus |
| Produces medial rotation at the shoulder | Subscapularous and teres major |
| produces lateral rotation at the shouder | infraspinatus and teres minor |
| produces flexion and adduction at shoulder | coracobrachialis |
| produces flexion at the the shoulder | pextoralis major |
| produces extension at the shoulder | latissimus dorsi |
| rotator cuff | supraspinatus, infraspinatus, subscapularious, teres minor |
| flexors of the elbow | brachialis, brachioradialis, bicpes brachii |
| extensors of the elbow | triceps brachii, anconeus |
| Flexors of the wrist | palmaris longus, flexor carpi radialis, flexor carpi ulnaris |
| Extensors of the wrist | Extensors carpi radialis, extensors carpi ulnaris |
| pronates | pronator teres and pronator quadratus |
| supines | supinator |
| Gluteal muscles | Gluteus maximus, minimus, medius, and tensor fisciae latae |
| Tensor fisciae latae | stabilizes Iliotibial tract |
| Works with gluteus maximus | Tensor fisciae latae |
| THe band of collagen fibers that laterally braces teh knee | Iliotibial tract |
| lateral rotators | piriformis and obturator |
| Muscles that move the thigh: adductors | adductor longus, brevis, magnus, and pectineus, gracilis |
| Iliopsoas | Iliacus and psoas major |
| Flexors of the knee | Hamstrings, sartoreus, and popliteus |
| Hamstrings are made up of ________. | Biceps femoris, semimembrosus, semitendinsus |
| Originates at the superior acetabulum | Sartoreus |
| Rotates the tibia to unlock the knees | Popliteus |
| Extensors of the knee | Four muscles of the quadriceps femoris |
| What muscles make up the quadriceps femoris | 3 Vastus muscles and 1 rectus femoris muscle |
| Muscles that produces extension at ankle (plantar flexion) | gastrocnemius, soleus, fibularis and tibialis posterior |
| Muscles that produce flexion (dorsiflexion) | tibialis anterior |
| Shared by the gastrocnemius and soleus muscle | Calcaneal tendon (achilles tendon) |
| tibialis anterior | opposes the gastrocnemius muscle |
| Triceps bracchi | Extensor of elbow. Origin: Scapula Insertion: olecranon |
| Anconeus | Extends elbow. Opposes brachialis |
| opposes brachilais | anconeus |
