|
What nerve innervates muscles that extend the carpus?
a. ulnar b. radial c. median d. musculocutaneous e. two of the above |
Radial
|
|
|
The lateral epicondyle of the humerus serves as a common point of origin for the muscles that flex the carpus and digits.
a. True b. False |
False; the medial epicondyle is the common point for flexors. The lateral epicondyle is a common attachment for extensors.
|
|
|
The triceps brachii muscle inserts on the olecranon of the ulna.
a. True b. False |
True
|
|
|
The pronator teres muscle will pronate the forearm and flex the elbow.
a. True b. False |
True
|
|
|
Which of the following muscles will supinate the forearm? (MACA)
a. palmaris longus b. supinator c. flexor carpi ulnaris d. biceps brachii e. extensor carpi ulnaris |
Supinator
Biceps brachii |
|
|
Which of the following muscles will flex the distal interphalangeal joint of digits 2-5?
a.flexor digitorum communis b. flexor digitorum profundus c. flexor digitorum superficialis d. flexor phalanges distalis e. none of the above |
Flexor digitorum superficialis: it flexes the proximal interphalangeal joint
|
|
|
The brachioradialis muscle will ____________ the elbow joint.
a. Flex b. Extend |
Flex
|
|
|
The flexor carpi ulnaris muscle will abduct the hand.
a. True b. False |
False; the flexor carpi ulnaris muscle will adduct the carpus (ulnar deviate).
|
|
|
The tendon of the extensor pollicus brevis muscle forms the ulnar border of the anatomic border.
a. True b. False |
False: It forms the radial (lateral) border along with the abductor pollicus longus.
The extensor pollicus longus forms the ulnar (medial) border |
|
|
The ulnar nerve innervates the muscles of the thenar eminence.
a. True b. False |
False; the median nerve forms the Thenar eminence
|
|
|
The iliacus muscle will flex the hip.
a. True b. False |
True; the iliacus muscle will also laterally rotate the hip.
|
|
|
The rectus femoris muscle attaches on the ASIS.
a. True b. False |
False; rectus femoris attaches on AIIS. The Tensor fascia latae attaches on ASIS.
|
|
|
Could a patient who experienced a trauma in which the femoral nerve was severed just as it formed, still extend the knee?
a. yes b. no |
No: beacause all of the quadricep muscles are responsible for extension of the knee and the femoral nerve is the only one that innervates these muscles.
|
|
|
The _____ is a common point of attachment for the hamstring muscles.
a. symphysis pubis b. ischial tuberosity c. ASIS d. PSIS e. pubic tubercle |
Ischial tuberosity
|
|
|
The __________ nerve is seen in the quadrangle space.
a. radial b. musculocutaneous c. axillary |
Axillary nerve because this space is between Teres major/minor and biceps brachii muscles.
|
|
|
The gluteus maximus muscle will extend and rotate the hip joint medially.
a. True b. False |
false; gluteus maximus extends and laterally rotates the thigh.
|
|
|
The piriformis muscle will laterally rotate the femur at the hip joint .
a. True b. False |
True; it will also extend thigh and abduct flexed thigh.
* This muscle allows you to find the sciatic nerve |
|
|
Which of the following muscles will flex the knee? MACA
a. soleus b gastrocnemius c. semimembranosus d. semitendinosus e. biceps femoris |
Biceps femoris
Semitendinosus Semimembranosus Gastrocnemius |
|
|
Which of the following muscles will plantar flex the foot? MACA
a. gastrocnemius b. peroneus brevis c. tibialis anterior d. tibialis posterior e. peroneus tertius |
Soleus
Gastrocnemius Tibialis posterior Peronius brevis * Muscles on the posterior aspect will plantar flex the foot. Muscles on the anterior aspect will dorsiflex the foot. |
|
|
Which of the following muscles will invert the foot at he ankle? (MACA)
a. peroneus tertius b. peroneus brevis c. peroneus longus d. tibialis anterior e. tibialis posterior |

a. tibial nerve b. common peroneal nerve c. obturator nerve d. femoral nerve e. inferior gluteal nerve |
Common (deep) peroneal nerve
|
|
|
What three muscles attach at the pes aserinus? (MACA)
a. sartorius b. tensor fascia latae c. soleus d. gracilis e. semitendinosus |
Sartorius
Gracilis Tensor fascia latae |
|
