What is a posterior landmark of the humerus?
Posterior Markings of the Humerus Bone: Head (Caput humeri) is a large, rounded, prominence that extends medially from the bone’s proximal end. It articulates with the glenoid fossa of the scapula to form the glenohumeral joint or shoulder joint.
What is the back of the humerus called?
corpus humeri
The posterorsuperior part of the shaft has a crest, beginning just below the surgical neck of the humerus and extends till the superior tip of the deltoid tuberosity. This is where the lateral head of triceps brachii is attached….Shaft.

What is the bony ridge of the humerus called?
The prominent bony projection on the medial side is the medial epicondyle of the humerus. The much smaller lateral epicondyle of the humerus is found on the lateral side of the distal humerus. The roughened ridge of bone above the lateral epicondyle is the lateral supracondylar ridge.
What is a bony landmark?
Any place on the skin surface where the underlying bone is normally close to the surface and easily palpable.
Which bony landmark of the humerus articulates with the ulna to form the elbow joint?
trochlea
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.
What are the parts of the humerus?
It consists of a proximal end, a shaft and a distal end, all which contain important anatomical landmarks. The humerus articulates with the scapula proximally at the glenohumeral joint so it participates in the movements of the shoulder.
What is spiral groove of humerus?
The radial sulcus ( also known as the musculospiral groove, radial groove, or spiral groove) is a broad but shallow oblique depression for the radial nerve and deep brachial artery. It is located on the center of the lateral border of the humerus bone.

Where are the bony landmarks?
Bony Landmarks
- Iliac crest – the highest point of the pelvis, extending anterior to posterior.
- Anterior superior iliac spine – a sharp notch anterior to the iliac crest.
- Posterior superior iliac spine – the most posterior aspect of the iliac crest, identified by dimples at approximately the level of S2.
What is the difference between bones and bony landmarks?
We have 206 to 213 bones in the human body. The points where bones touch the skin, we call landmarks. These are bony areas that show at the surface.
