What are the 'Bony Landmarks' in the human body?

Answer 1

The 'bony landmarks' of the human body are distinguishing features found on the bones of the skeletal system. Each bone of the human body has at least one or two "landmarks" that serve to distinguish that bone from other bones. A bony landmark could be anything from a line or a notch in its surface to a large bump or projection. These landmarks are often named for what they are and where they are( a notch in the bone at the top of the scapula = suprascapular notch), but the names of the landmarks vary widely. Clinically, these bony features are important in palpation, the physical examination of the tissues of the body, often done with the hands/fingers, because they serve as the somewhat fixed landmarks of the body. Hence, bony landmarks.

To give an example, one of the most well known landmarks of the hip/thigh region is the Greater Trochanter. The Greater Trochanter is a large, bony bump on the lateral aspect of the femur(the hip bone). To palpate or feel this landmark, a clinician will place his/her hand on the side of the thigh close to the abdomen and will externally and internally rotate the hip on the same side to feel the large greater trochanter roll underneath his/her palm. This landmark is important because many of the muscles that create movements at the hip joint attach on or around the greater trochanter.

There are literally hundreds of bony landmarks all over the human body, which comes as no surprise as there are approximately 206 bones in the average human adult skeleton. Not all can be easily palpated, but they are used regularly by massage therapists, physical therapists, occupational therapists, and many other medical professionals, in the treatment of their patients. ~BLJ, SPTA Some other examples are the distal end of radius (the bone of forearm) here we can feel pulsation of radial artery. The medial malleolus in the foot, the artery and the nerve that supply the sole of the foot pass about 2.5 cm behind this bony hump. On the left side of chest the speeln lies beneath the 9th 10th and 11th ribs. The ulnar nerve (the nere supplies most of the small muscles of hand) passes just under the medial condyle (the inner part of elbow) of humerus (bone of arm) and we can easily feel it.

Answer 2

A "bony landmark" is a groove or prominence on a bone that acts as a guide to find or relate other body structures.

Examples are those whose names end with facet, canal, fossa, fovea, condyle, tubercle, tuberosity, process, spine, sinus, etc.

Examples:

Olecranon fossa (on the posterior aspect of the humerus)

Lateral/medial epicondyle (on the inferior aspect of the humerus)

Acromial facet (on the clavicle)

Jugular notch (on the manubrium)

Answer 3

The ends of bones around joints are the most common places for muscles to insert so as to move the body. Some of the landmarks made by these insertion sites are condyles, fossas, styluses and other protuberances and depressions.

Answer 4

• Hyoid bone - the hyoid bone is suspended by the hyoid muscle, below the floor of the mouth.
• Thyroid cartilage - the thyroid cartilage forms part of the largyngeal prominence and overlies the thyroid and larynx.
• Cricoid cartilage - the cricoid forms a cartilaginous ring below the thyroid cartilage

Answer 5

Any bony prominence is named by "process". E.g. "mastoid process of the skull."
