Osteology
This large lateral projection of the proximal femur serves as the attachment site for the gluteus medius and minimus muscles.
What is the greater trochanter?
This muscle initiates shoulder abduction.
What is the supraspinatus muscle?
This ligament surrounds the head of the radius/
What is the annular ligament?
I separate the supraspinous and infraspinous fossae.
What is the spine of the scapula?
This muscle shares its insertion with the gastrocnemius via the calcaneal tendon but does not cross the knee.
What is the soleus?
This scapular landmark articulates with the humeral head.
What is the glenoid cavity?
This muscle is the only rotator cuff muscle that inserts on the lesser tubercle.
What is the subscapularis muscle?
This ligament prevents anterior displacement of the femur relative to the tibia.
What is the PCL?
I am the only carpal bone that possesses a hook.
What is the hamate?
This ligament connects adjacent metacarpal heads while still permitting flexion and extension at the MCP joints.
What is the deep transverse metacarpal ligament?
During elbow extension, this process fits into a depression on the posterior distal humerus.
What is the olecranon process of the ulna?
A patient cannot actively supinate the forearm against resistance when the elbow is flexed to 90°. This muscle is most likely injured.
What is the biceps brachii?
This ligament is likely the first contact with a posterior disc buldge.
What is the posterior longitudinal ligament of the spine?
I transmit the suprascapular nerve beneath me but the suprascapular artery passes above me.
What is the suprascapular notch?
This muscle originates from the anterior surface of the scapula yet inserts on the lesser tubercle of the humerus.
What is the subscapularis?
A patient fractures the surgical neck of the humerus. The fracture lies immediately distal to these two important proximal landmarks.
What are the greater and lesser tubercles of the humerus?
This muscle both flexes the hip and stabilizes the lumbar spine, yet is composed of three separate muscles that share a common distal insertion.
What is the iliopsoas?
An athlete sustains an inversion ankle sprain with the foot plantarflexed. This ligament is statistically the first to fail.
What is the anterior talofibular ligament?
I serve as the attachment for the adductor magnus tendon and lie immediately superior to the medial femoral epicondyle.
What is the adductor tubercle of the femur?
This bony landmark is shared by the ilium, ischium, and pubis.
What is the acetabulum?
This bony landmark serves as the insertion for iliopsoas and is not directly palpable on physical examination.
What is the lesser trochanter?
This muscle is innervated by the tibial nerve, passes posterior to the medial malleolus, inserts primarily on the navicular, and is considered one of the most important dynamic stabilizers of the medial longitudinal arch.
What is the tibialis posterior?
This ligament is considered the strongest ligament in the human body, resists hip hyperextension during standing, and has a characteristic Y-shaped appearance.
What is the iliofemoral ligament?
I separate the greater and lesser sciatic foramina and provide attachment for both the sacrospinous ligament and coccygeus muscle.
What is the ischial spine?
A patient presents with weakness in shoulder abduction beyond 15°, numbness over the lateral shoulder, and a fracture involving the surgical neck of the humerus. The muscle primarily responsible for the weakness is this one.
What is the deltoid?
