What are the processes near the head of the humerus?
The humeral upper extremity consists of a rounded head, a narrow neck, and two short processes (tubercles, sometimes called tuberosities). The body is cylindrical in its upper portion, and more prismatic below.
What is the large process lateral to the head of the femur?
Greater trochanter (Trochanter major) is a large, irregular-shaped process located lateral to neck and superior to shaft.
What muscle attaches to head of humerus?
Muscle Attachments
| Muscle | Attachment |
|---|---|
| Supraspinatus | Greater Tubercle |
| Infraspinatus | Greater Tubercle |
| Teres Minor | Greater Tubercle Upper Part of the Lateral Border |
| Subscapularis | Lesser Tubercle |
What is Diaphysis humerus?
The diaphysis is the main or midsection (shaft) of a long bone. It is made up of cortical bone and usually contains bone marrow and adipose tissue (fat). It is a middle tubular part composed of compact bone which surrounds a central marrow cavity which contains red or yellow marrow.
What side of the body does the humerus belong to?
The humerus is the bone in your upper arm. It’s located between your elbow and your shoulder, and consists of several parts that allow it to move freely in different directions. Your humerus has important functions related to both movement and support.
Is the head of the humerus a condyle?
Anatomical terms of bone The Condyle of humerus is the distal end of the humerus. It is made up of the capitulum and the trochlea.
Is the femur longer than the humerus?
Furthermore, the length and the average diameter of the femur are higher than that of the humerus. Besides, the femur is the largest bone of the human body while humerus is the second largest bone. In brief, femur and humerus are two of the largest long bones of the human body.
Which of the following bone markings on the femur is a point of articulation between bones?
Correctly match the following bone marking to its bone: Greater trochanter. Which of the following bone markings on the femur is a point of articulation between bones? Correctly match the following: Patella.
Can you move your arm with a broken humerus?
A fractured humerus or upper arm is extremely painful, and the patient may not be able to move their arm. Sometimes, the radial nerve (one of the main nerves in the arm) may be injured. This happens about 15% of the time. It is more common with fractures that happen closer to the base of the bone.
How is a humeral head fracture treated?
A humerus shaft fracture may be treated with or without surgery, depending on the fracture pattern and associated injuries (i.e., nerve injury or open fracture). A temporary splint extending from the shoulder to the forearm and holding the elbow bent at 90 degrees can be used for initial management of the fracture.
How strong is the humerus bone?
The humerus is a strong bone, analogous to the femur in the leg (which is the strongest bone in the body). It does not absorb the intensity of stress that the forearm bones do when you fall and catch yourself with your hands, since the humerus is farther up the chain of bones.
What is the end of the humerus?
The lower end of the humerus includes two smooth articular surfaces (capitulum and trochlea), two depressions (fossae) that form part of the elbow joint, and two projections (epicondyles). The capitulum laterally articulates with the radius; the trochlea, a spool-shaped surface, articulates with the ulna.
