What does the humerus look like?
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….

Where is the humerus bone located?
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.
What is the humerus anatomy?
The humerus is the largest bone of the upper extremity and defines the human brachium (arm). It articulates proximally with the glenoid via the glenohumeral (GH) joint and distally with the radius and ulna at the elbow joint.
What do you know about the osteology of upper end of the humerus?
Osteology. The humerus begins proximally as a rounded head and joins the greater and lesser tubercles via the anatomical neck of the humerus. The surgical neck is found just inferior to the tubercles where the shaft begins.
What is Subscap?
The subscapularis is a muscle in your shoulder that helps you internally rotate your arm. The subscapularis connects from your shoulder blade to your humerus, or upper arm bone. All the muscles of the rotator cuff, including the subscapularis, can tear from overuse, trauma, or age-related conditions.
Can you determine which side of the body the humerus is from?
Look for the deep olecranon fossa on the lower (distal) end. Rotate the humerus so that the capitulum and trochlea face YOU. If the capitulum is on the left side of the bone, it is a left humerus. If the capitulum is on the right side, it is a right humerus.
What is the funny bone called?
ulnar nerve
The ulnar nerve innervates muscles of the forearm, hand and two fingers (the ring and pinky fingers). It is believed to have been named the “funny bone,” because the nerve corresponds to the humerus bone (which sounds like humorous, as in funny).
What is osteology the study of?
Publisher Summary. Human osteology is the science that deals with human skeleton recovery and interpretation. Osteological work is often aimed at the identification of the relatively recently deceased and is usually done in a legal context.
How do you know which side of the humerus is?
How thick is the humerus bone?
The bone mineral density (BMD) was determined for the humeral head (HH), the surgical neck (SN), the greater tuberosity (GT) and lesser tuberosity (LT) using dual-energy x-ray absorptiometry. The mean cortical thickness was 4.4 +/- 1.0 mm.
