ANATOMICAL NECK Meaning and
Definition
-
The anatomical neck, in anatomy, refers to a specific region of the humerus bone located just below the head of the bone. It is a narrow, constricted area that serves as a transition point between the head and the greater tubercle of the humerus. This region is named "anatomical" because it represents the natural boundary or division between the head and the shaft of the humerus bone.
The anatomical neck is crucial for the functioning of the shoulder joint since it allows for the attachment of various muscles, tendons, and ligaments that support the movement and stability of the joint. It provides an attachment site for the rotator cuff muscles, including the supraspinatus and infraspinatus muscles, which are responsible for the rotation and abduction of the shoulder. Additionally, the anatomical neck is involved in articulation with the glenoid cavity of the scapula bone to form the glenohumeral joint, enabling the arm's movements.
Understanding the anatomical neck is important for healthcare professionals such as orthopedic surgeons, physical therapists, and radiologists since injuries or fractures in this specific region can have significant implications for shoulder function. The anatomical neck's location and structure play a crucial role in determining treatment options and prognosis for patients with shoulder-related issues.

Etymology of ANATOMICAL NECK
The term "anatomical neck" is used in the field of anatomy to refer to a specific region or structure in the human body.
Etymologically, the word "anatomical" derives from the Greek word "anatome", which means "dissection" or "cutting up". This reflects the origin and nature of the term, as it relates to the study of the structure and organization of the human body through dissection.
The word "neck" can be traced back to Old English, where it was spelled as "hnecca" and meant the same anatomical region. The term likely has its root in Proto-Germanic, the ancestor of multiple modern Germanic languages, including Old English, where it referred to the part of the body that connects the head and the torso.
