Chapter 6 Study Guide
True
Boney stability of elbow in full extension is enhanced by the elecronan process fitting into the elecronan fossa
False
Lateral epicondylitus is a condition that occurs less commonly than medial epicondylitus
True
Medial epicondylitus is also known as golfers elbow
True
Motion of the elbow primarily involves movement between articular surfaces of the humerus and ulna
False
Movement at the elbow by the forearm away from the shoulder is accurately described as term flexion
True
Normal boney limitation of elbow flexion is limited by the coranoid process fitting into the coronoid fossa
True
Positioning the forearm in pronation reduces the effectiveness of the biceps brachialis in flexing the elbow
True
Radial collateral ligament provides lateral stability to the elbow and is rarely injured
False
Radial head sits inside the capilum in place by the annular ligament
False
Scapula and clavicle serve as proximal attachments for muscles that flex and extend the elbow
False
Supination refers to internal rotary movement on ulna
True
The distal attachments for the radial joint muscle are rotated on the radius
False
The elbow is a hinge type joint that allows for internal and external rotation
False
The elecronan process is located on the medial aspect of the ulna
True
The insertion of the biceps Brachii muscle (Radial tuberosity)
False
The insertion of the brachialis muscle is coracoid process of the ulna
False
The insertion of the brachioradialis is the proximal end of the radius of the styloid process
False
The lateral supracondylar ridge is an anatomic landmark on the ulna
True
The origin of the biceps brachii muscle supraglenoid tubercle above the superior lip of the glenoid fossa
True
The pronator teres is innervated by the medial nerve
True
The ulna is much larger proximately than the radius
True
Triceps Brachii is the insertion of triceps of brachii is the olcreanon of ulna
True
When performing a pushup the biceps brachii is considered to be an antagonist muscle
True
When the arm is held in anatomical position, the radial tuberosity is in closed proximately to the lateral side of the ulna
False
While in an anatomical position the radius is medial in respect to the ulna
