The projection that forms the lower border of the trochlear notch, the coronoid process, enters the coronoid fossa of the humerus when the elbow is flexed. On the outer side is the radial notch, which articulates with the head of the radius. The head of the bone is elsewhere roughened for muscle attachment.

What is the name of the fossa that articulates with the humerus?

The olecranon fossa is a deep triangular depression on the posterior side of the humerus, superior to the trochlea. It provides space for the olecranon of the ulna during extension of the forearm.

Which distal feature of the humerus articulate with the proximal head of the radius?

The Distal Humerus:

The coronoid fossa articulates with the coronoid process of the ulna, and the radial fossa articulates with the radial head of the radius. Moreover, just inferior to the coronoid fossa, the capitulum and the trochlea can be identified which promote articulation with the radius and the ulna.

Which of the following structures articulates with the head of the radius 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).

Which part of the scapula articulates with the head of the humerus?

The scapula articulates with the humerus at the glenoid fossa and the clavicle at the acromion process.

What are the 3 fossa of the scapula?

The scapula has three processes: the acromion, the spine, and the coracoid process. ... Above the spine is the supraspinous fossa and below it is the infraspinous fossa. A ridge runs down the infraspinous fossa near the lateral border from the glenoid cavity to just above the inferior angle.

What 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 structure articulates with the head of the radius?

The head of the radius has a cylindrical form, and on its upper surface is a shallow cup or fovea for articulation with the capitulum of the humerus.

Which structure articulates with the trochlea of the humerus?

In the human arm, the humeral trochlea is the medial portion of the articular surface of the elbow joint which articulates with the trochlear notch on the ulna in the forearm.

Which feature of the humerus articulates with the radius?

capitulum: At the distal head of the humerus, it articulates with the radius of the forearm.

What bone articulates with the radial fossa?

A large central condyle which has two articular components – the capitulum which articulates with the radius, and the trochlea which articulates with the ulna.

Which fossa are found on the anterior side of the humerus?

The coronoid fossa is the medial hollow part on the anterior surface of the distal humerus. The coronoid fossa is smaller than the olecranon fossa and receives the coronoid process of the ulna during maximum flexion of the elbow.

Which bones articulates with the humerus?

humerus, long bone of the upper limb or forelimb of land vertebrates that forms the shoulder joint above, where it articulates with a lateral depression of the shoulder blade (glenoid cavity of scapula), and the elbow joint below, where it articulates with projections of the ulna and the radius.

Where is radial fossa of humerus?

The radial fossa is a slight depression found on the humerus above the front part of the capitulum. It receives the anterior border of the head of the radius when the forearm is flexed.

What articulates with the Coronoid fossa?

part of ulna

…of the trochlear notch, the coronoid process, enters the coronoid fossa of the humerus when the elbow is flexed. On the outer side is the radial notch, which articulates with the head of the radius. The head of the bone is elsewhere roughened for muscle attachment.

Where is glenoid fossa?

The glenoid fossa is the socket of the shoulder joint. This part of the shoulder is a ball and socket joint. The head of the Humerus fits into the Glenoid fossa, though it is a shallow socket.

Which vertebrae articulates with the skull?

atlas: the first cervical vertebra (C1), lying directly under the skull, through which the head articulates with the neck.

Where is the head of radius?

The radial "head" is the knobby end of the radius where it meets the elbow.

What bone articulates with the proximal head of the upper arm?

The humerus is the single bone of the upper arm region (Figure). At its proximal end is the head of the humerus. This is the large, round, smooth region that faces medially. The head articulates with the glenoid cavity of the scapula to form the glenohumeral (shoulder) joint.

What does the Trochlea articulate with?

The capitulum laterally articulates with the radius; the trochlea, a spool-shaped surface, articulates with the ulna.

Where does the ulna articulate with the humerus?

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.

Where is the humerus head?

Where is the humerus located? The humerus bone is located in the upper arm, between the shoulder joint and the elbow joint. The shoulder joint, also known as the glenohumeral joint, is a ball and socket joint. The ball is the humeral head, and the socket is the glenoid fossa of the scapula.

Which bone articulates with the humerus quizlet?

Humerus? -Articulates with scapula, ulna, and radius.

Which bone articulates with the scapula quizlet?

Scapula articulates with clavicle at the acromioclavicular joint and with the humerus at the glenohumeral joint. Scapula? -Clavicle articulates with the manubrium of the sternum and laterally with acromion of scapula.

What bone articulates with the scapula?

In the dry skeleton, here's the clavicle, here's the scapula. The proximal long bone of the upper extremity, the humerus, articulates with the scapula at the shoulder joint.
