DORSUM SCAPULAE Meaning and
Definition
-
Dorsum scapulae, also known as the scapular spine, is a term used in anatomy to refer to a prominent ridge of bone found on the posterior surface of the scapula, or shoulder blade. The scapula is a flat, triangular-shaped bone located on the upper back and plays a crucial role in the movement and stabilization of the upper limb.
The dorsum scapulae is a bony ridge that extends longitudinally along the posterior aspect of the scapula. It starts at the medial border of the scapula, also called the vertebral border, and runs towards the lateral border, also known as the axillary border. This ridge has a convex shape and is easily palpable on the surface of the skin.
The dorsum scapulae provides attachment points for various muscles, including the trapezius, rhomboids, and deltoids. These muscles are involved in movements of the shoulder joint, such as elevation, retraction, and rotation of the scapula.
Studying the dorsum scapulae is important for healthcare professionals, physiotherapists, and anatomists as it allows for accurate identification of the scapular region and serves as a landmark for understanding the attachments and actions of surrounding muscles. Additionally, knowledge of the dorsum scapulae is essential for diagnosing and treating injuries or conditions affecting the scapula or related structures.

The term "dorsum scapulae" is a Latin phrase that refers to the "back of the scapula" or shoulder blade. Here is the breakdown of its etymology:
1. Dorsum: This Latin word means "back" or "ridge". It is derived from the Proto-Indo-European root *dʰers-, which also gave rise to the Greek word "dóron" meaning "gift" and the English word "dorsal" meaning "pertaining to the back".
2. Scapulae: This is the plural form of "scapula", which is a Latin term referring to the shoulder blade. The word "scapula" itself could be traced back to the Proto-Indo-European *kap- meaning "shoulder" or "to seize".
