What part of the humerus articulates with the radius and ulna?
The distal end of the humerus has two articulation areas, which join the ulna and radius bones of the forearm to form the elbow joint. The more medial of these areas is the trochlea, a spindle- or pulley-shaped region (trochlea = “pulley”), which articulates with the ulna bone.
What bone articulates with the humerus?
The humerus articulates with the scapula proximally at the glenohumeral joint so it participates in the movements of the shoulder. Also, the humerus has distal articulations with the radius and ulna at the elbow joint.
What articulates with the distal humerus?
The anatomy of the distal humerus is highly complex, as it articulates with both the radius and ulna and allows for motion in multiple planes.
What part of the radius articulates with the humerus quizlet?
The radius articulates proximally with the humerus at the capitulum and medially with the ulna on both proximal and distal ends. Distally, the radius articulates with two carpal bones of the wrist: the lunate (medially) and the scaphoid (laterally).
Is the radius is distal to the humerus?
The proximal end of the radius makes up the lateral (outer) edge of the elbow joint at the distal end of the humerus. The distal end of the radius attaches to the wrist just before the thumb.
Which bone articulates with the humerus quizlet?
clavicle articulates with the humerus. vertebral column articulates with the sacrum. clavicle articulates with the manubrium of the sternum.
Where does the humerus articulate with the ulna?
Elbow. The ulna articulates with the humerus at its most proximal point forming the elbow in a hinge joint. It is the trochlea of the humerus which sits in the semi-lunar notch of the ulna to form this joint.
What part of the humerus articulates with the ulna?
trochlea
The ulna articulates with the humerus at its most proximal point forming the elbow in a hinge joint. It is the trochlea of the humerus which sits in the semi-lunar notch of the ulna to form this joint.
What does the radial notch articulate with?
On the lateral aspect of the proximal ulna and just distal to the trochlear notch lies the shallow, rounded depression called the radial notch. The radial notch articulates with the circumference of the radial head and forms the proximal radioulnar joint.
How does the humerus and ulna articulate?
The ulna articulates with the humerus at its most proximal point forming the elbow in a hinge joint. It is the trochlea of the humerus which sits in the semi-lunar notch of the ulna to form this joint.
What part of the scapula articulates with the humerus?
glenoid fossa
The scapula articulates with the humerus at the glenoid fossa and the clavicle at the acromion process.
What part of the ulna articulates with the humerus?
trochlea of
Elbow. The ulna articulates with the humerus at its most proximal point forming the elbow in a hinge joint. It is the trochlea of the humerus which sits in the semi-lunar notch of the ulna to form this joint.
Which bone articulates with the ulna?
the humerus
Which part of the scapula articulates with the humerus quizlet?
The glenoid fossa of the scapula articulates with the head of the humerus to form the glenohumeral joint.
What articulates with the ulna?
The ulna is the longest, thinnest bone of the forearm. It articulates proximally with the trochlea of the humerus and with the head of the radius. Distally it articulates with the ulnar notch of the radius and with an articular disk that separates it from the carpal bones.
How does the radius and ulna articulate?
The radius articulates with the ulna in a synovial pivot joint. The radial head rotates within the annular ligament and radial notch on the ulna to produce pronation of the forearm. The radius and ulna also articulate distally in reverse to their articulation at the elbow to produce supination.
What does the ulna articulate with?
Proximally the ulna articulates with the humerus and the radius. Distally it contacts the carpus or wrist. The trochlear notch is the deep semicircular surface for articulation with the trochlea of the humerus. The olecranon is the squared process extending proximal to the trochlear notch.
Does the humerus articulate with the clavicle?
The scapula (shoulder blade) lies on the posterior aspect of the shoulder. It is supported by the clavicle, which also articulates with the humerus (arm bone) to form the shoulder joint.
What part of the humerus articulates with the scapula to form the shoulder joint quizlet?
What part of the humerus articulates with the scapula to form the shoulder joint? The head of the humerus articulates with the glenoid cavity of the scapulae to form the shoulder joint.
