Is the head of the humerus at the proximal or distal end?

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. The margin of the smooth area of the head is the anatomical neck of the humerus.

What is the distal end of the humerus?

The distal humerus is the lower end of the humerus. It forms the upper part of the elbow and is the spool around which the forearm bends and straightens. The radial head is the knobby end of the radius where it meets the elbow.

What is the difference between the distal end of a humerus and the distal end of a femur?

Femur refers to the bone of the thigh or the upper hindlimb, articulating at the hip and the knee, while humerus refers to the bone of the upper arm or forelimb, forming joints at the shoulder and the elbow.

What is the proximal humerus?

The proximal area of the humerus is the portion near the arm’s attachment to the body. Bony landmarks in this part of your arm include the greater tuberosity, lesser tuberosity, surgical neck and anatomical neck.

Where is proximal end of humerus?

The most proximal portion of the humerus is the head of the humerus, which forms a ball and socket joint with the glenoid cavity on the scapula. [1] Just inferior to the head of the humerus is the anatomical neck of the humerus, which divides the head of the humerus from the greater and lesser tubercles.

Where does the humerus begin and end?

The proximal humerus connects to the shoulder through the glenoid fossa of the scapula, forming the glenohumeral joint. The distal humerus articulates at the elbow to the radius and ulna in the forearm.

Is the humerus proximal or distal to the ulna?

Humerus: The humerus attaches proximally to the scapula (shoulderblade) at the humeral head and distally with the radius and ulna (lower-arm bones) at the trochlea and capitulum, respectively. The proximal portion of the humerus can be divided into three parts.

Which landmark is found on the distal end of the humerus?

Which of the following landmarks is found on the distal end of the humerus? The lateral epicondyle of the humerus is on the lateral distal surface of the bone. It serves as a site of muscle attachment.

What muscles insert on proximal end of the humerus?

The proximal end of the humerus consists of a head, an anatomical neck and the greater and lesser tubercles….From superior to inferior, the muscles that attach at these impressions are the:

• supraspinatus.
• infraspinatus.
• teres minor.

Where is upper end of left humerus?

The humerus — also known as the upper arm bone — is a long bone that runs from the shoulder and scapula (shoulder blade) to the elbow. Fractures of the humerus are classified in one of two ways: proximal humerus fracture or humerus shaft fracture.

What muscles attach to distal humerus?

The biceps brachii, brachialis, and brachioradialis (which attaches distally) act to flex the elbow.

What is the proximal end of the humerus?

Proximal end. The proximal end of the humerus consists of a head, an anatomical neck and the greater and lesser tubercles. The head is a hemispheroidal shape, with hyaline cartilage covering its smooth articular surface.

What is the humerus bone?

The humerus is the longest and largest bone of the upper limb. It consists of a proximal end, a shaft and a distal end, all which contain important anatomical landmarks.

What is a distal humerus fracture?

Distal humerus fractures are uncommon injuries in adults. These fractures occur near the elbow joint. These fractures most often require surgical treatment unless the bones are held in proper position.

Is the humerus distal to the elbow?

Humerus. Also, the humerus has distal articulations with the radius and ulna at the elbow joint . The nature of the elbow joint enables the movements that are limited to the arm and forearm, and cannot be performed within the other parts of the body, such as supination and pronation.
