Osteology
This carpal bone is most commonly fractured when falling on an outstretched hand.
What is the scaphoid?
This nerve passes through the carpal tunnel and is compressed in carpal tunnel syndrome.
What is the median nerve?
This superficial vein runs on the lateral side of the forearm and drains into the axillary vein.
What is the cephalic vein?
This group of four muscles stabilizes the glenohumeral joint.
What are the rotator cuff muscles?
This autosomal dominant condition is the most common cause of dwarfism and is characterized by impaired longitudinal bone growth.
What is achondroplasia?
This part of the humerus is most commonly fractured in proximal humeral fractures.
What is the surgical neck?
This nerve innervates the deltoid and teres minor muscles and can be injured in shoulder dislocations.
What is the axillary nerve?
This superficial vein is commonly used for venipuncture and connects the cephalic and basilic veins.
What is the median cubital vein?
This muscle forms the anterior wall of the axilla and assists in medial rotation and adduction of the humerus.
What is pectoralis major?
A 70-year-old man complains of persistent groin pain after falling on ice. X-rays reveal a fracture at the femoral neck. This is a common injury in older adults with this condition.
What is osteoporosis?
This part of the sternum articulates with the clavicles and the first pair of ribs.
What is the manubrium?
Damage to this nerve causes a “claw hand” deformity, characterized by hyperextension of the MCP joints and flexion of the PIP and DIP joints in the 4th and 5th digits.
What is the ulnar nerve?
This vein is a continuation of the subclavian vein and begins at the lateral border of the 1st rib.
What is the axillary vein?
The boundaries of the cubital fossa include this muscle on the lateral side and this muscle on the medial side.
What are the brachioradialis (lateral) and pronator teres (medial)?
This condition is characterized by defective osteoclastic activity, resulting in dense but weak bones, and may present with a radiological "Erlenmeyer flask" deformity of the metaphyses.
What is osteopetrosis?
This carpal bone has a hook that provides attachment for the flexor retinaculum.
What is the hamate?
This nerve is a branch of the posterior cord of the brachial plexus and innervates the triceps brachii muscle.
What is the radial nerve?
This deep vein of the upper limb is formed by the union of the radial and ulnar veins.
What is the brachial vein?
This tendon runs through the cubital fossa and can be palpated just medial to the brachioradialis.
What is the biceps brachii tendon?
This disease is marked by a sequence of osteolytic, mixed osteoblastic-osteoclastic, and osteosclerotic phases, and shows a mosaic pattern of lamellar bone on histology.
What is Paget disease of the bone?
This fossa on the posterior side of the humerus accommodates part of the ulna during elbow extension.
What is the olecranon fossa?
(it accommodates the olecranon of the ulna)
This nerve, derived from the upper trunk of the brachial plexus, innervates the supraspinatus and infraspinatus muscles.
This superficial vein runs along the medial side of the forearm and arm and drains into the axillary vein.
What is the basilic vein?
This muscle in the posterior compartment of the forearm is responsible for extending and abducting the wrist and is innervated by the radial nerve.
What is the extensor carpi radialis longus?
This bone disease presents with a cold abscess, vertebral collapse, and kyphosis, and is commonly associated with tuberculosis infection spreading to the spine.
What is Pott disease (tuberculous spondylitis)?
