What does the condyle of the humerus articulate with?
Description. The condyle of humerus is the whole distal end except the epicondyles. The condyle articulates with the radius and ulna forming the elbow joint.
Which condyle of the humerus articulates with the ulna?
The name of the medial condyle of the humerus that articulates with the ulna is the trochlea.
What part of the humerus articulates with the humerus?
The humerus is a long bone of the upper limb, which extends from the shoulder to the elbow. The proximal aspect of the humerus articulates with the glenoid fossa of the scapula, forming the glenohumeral joint.
What part of the humeral condyle articulates with the radius?
The capitulum
The capitulum, the lateral part; that articulates with radius.
Does the humerus articulate with the radius and ulna?
The humerus is the single bone of the upper arm region. It articulates with the radius and ulna bones of the forearm to form the elbow joint. Distally, the humerus becomes flattened.
Which process of the humerus articulates with the ulna?
Trochlea of the humerus articulates with the ulna and capitulum with the radius to form the elbow joint. Trochlea and capitulum are condyles of the humerus.
What are the articulation points between the humerus 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.
How many articulations does the humerus have?
2
These 3 articulations, forming 2 different aspects, allow flexion and extension of the elbow, as well as supination and pronation of the forearm and wrist at the elbow.
What articulates with the head of the humerus?
The head of the humerus articulates with the glenoid fossa of the scapula to form the glenohumeral joint.
What is the condyle of humerus?
The condyle of humerus is the whole distal end except the epicondyles. The condyle articulates with the radius and ulna forming the elbow joint. In dog and cats, the condyle is divided in two parts: The trochlea, the medial part, that articulates with ulna. The capitulum, the lateral part; that articulates with radius.
What on the humerus articulates with the radius?
capitulum: At the distal head of the humerus, it articulates with the radius of the forearm.
Where does the head of the humerus articulate?
Articulations. At the shoulder, the head of the humerus articulates with the glenoid fossa of the scapula. More distally, at the elbow, the capitulum of the humerus articulates with the head of the radius, and the trochlea of the humerus articulates with the trochlear notch of the ulna.
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.
What part of humerus articulates with the scapula?
humeral head
The proximal portion of the humerus can be divided into three parts. The rounded humeral head projects medially and articulates with the glenoid cavity of the scapula. Immediately adjacent to the head is the narrower anatomical neck, which allows for a wider range of movements of the head within the shoulder joint.
What is the articulation of the humerus ulna and radius called?
The elbow joint is formed by the articulation between the trochlea of the humerus and the trochlear notch of the ulna, plus the articulation between the capitulum of the humerus and the head of the radius. The proximal radioulnar joint is the articulation between the head of the radius and the radial notch of the ulna.
Does the humerus have condyles?
The condyle of humerus is the distal part of humerus (including the capitulum, trochlea, olecranon fossa, coronoid fossa, radial fossa, medial and lateral epicondyles).
What structures comprise the condyle in the humerus?
The distal portion of the humerus ends with an area referred to as the condyle, which is composed of the trochlea, capitulum, olecranon, coronoid and radial fossae.
What are the specific names of the condyles of the humerus?
Description. The condyle of humerus is the distal part of humerus (including the capitulum, trochlea, olecranon fossa, coronoid fossa, radial fossa, medial and lateral epicondyles).
What part of humerus articulates with scapula?
What does the articular part of the humerus consist of?
The articular part of the humerus is a modified condyle and is wider transversely. It articulates with both the ulna and radius and consists of a medial trochlea and a lateral capitulum, which are separated by a faint groove.
What are the three surfaces of the humerus?
There are three surfaces (antero-lateral, antero-medial and posterior surfaces) and three borders (anterior, lateral and medial borders). The condyle of the humerus articulates with the radius and ulna. It is composed of the trochlea, capitulum, and medial and lateral epicondyles.
What is a lateral humeral condyle fracture?
Lateral humeral condyle fractures also referred to simply as lateral condyle fractures (in the appropriate context), are relatively common elbow fractures that predominantly occur in children.
What is the capitulum of the humerus?
The capitulum is a convex and rounded projection that covers the anterior and inferior surfaces of the lateral condyle of the humerus. Unlike the trochlea, it doesn’t cover the posterior surface. It articulates with the head of the radius.
