EPICONDYLIC RIDGES Meaning and
Definition
-
Epicondylic ridges, also known as epicondylar ridges, refer to prominent bony characteristics found on the medial (inner) and lateral (outer) sides of the distal end of the humerus bone. These ridges serve as attachment sites for muscles, tendons, and ligaments in the elbow region.
The medial epicondylar ridge, also called the medial epicondyle, is located on the inner side of the humerus, slightly above the elbow joint. It serves as an attachment point for muscles involved in flexion and pronation of the forearm, such as the flexor carpi radialis and pronator teres muscles. In addition, the tendons of the forearm muscles that control wrist and finger movement attach to this ridge.
On the outer side of the humerus, the lateral epicondylar ridge, or lateral epicondyle, is located. It provides attachment sites for muscles involved in extension and supination of the forearm, such as the extensor carpi radialis brevis and extensor carpi ulnaris muscles. Similarly, the tendons of the forearm muscles that control wrist and finger extension attach here.
The prominence of these epicondylic ridges varies among individuals and can be more pronounced in those who engage in repetitive upper limb activities. Epicondylic ridges are important anatomical features that provide structural support and stability to the elbow joint by allowing the attachment of various muscles, tendons, and ligaments.

The two borders separating the anterior and posterior surfaces of the humerus, running up from the condyles; the external (margo lateralis) gives attachment to the brachioradialis and extensor carpi radialis longior muscles, the internal (margo medialis), as well as the external, gives attachment to the intermuscular septa.

Etymology of EPICONDYLIC RIDGES
The etymology of the word "epicondylic ridges" can be broken down as follows:
1. Epicondylus: The term "epicondylic" is derived from the Latin word "epicondylus", which means "epicondyle". An epicondyle refers to a rounded prominence at the end of a bone, typically located near a joint. In the case of the epicondylic ridges, it refers to the bony ridges found near the epicondyles of the humerus bone (the long bone of the upper arm).
2. Ridge: The word "ridge" comes from the Old English word "hrycg", meaning "back" or "spine". In the context of anatomy, a ridge refers to a long, narrow, elevated strip of bone.
