Scapulum is a noun that refers to the technical anatomical term for the human shoulder blade, which is a flat triangular bone located in the upper back region of the body. It serves as a crucial connecting link between the arm and the trunk, forming part of the shoulder girdle along with the clavicle. The scapulum plays a vital role in various movements of the upper limbs, enabling the mobility and stability of the shoulder joint.
Typically, the scapulum is positioned on the posterior side of the thorax, extending from the second to the seventh rib. It is characterized by its unique shape, resembling a triangle with two angles and three edges. The superior angle is the uppermost point, while the lateral angle is located towards the arm. The lateral angle also houses the glenoid cavity, forming a joint with the head of the humerus bone to create the shoulder joint.
The scapulum is connected to the rest of the skeletal system through several muscles, tendons, and ligaments, which allow for various movements such as abduction, adduction, flexion, extension, and rotation of the upper limbs. Additionally, it provides support and stability to the upper body during activities involving arm movement.
Overall, the scapulum plays a crucial role in the structural and functional integrity of the shoulder region, enabling a wide range of movements necessary for daily activities and physical capabilities.
The word "scapulum" derives from the Latin term "scapula", which means "shoulder blade" or "shoulder". In Latin, the word is a diminutive form of "scapus", meaning "shaft" or "stalk". The term "scapula" originally denoted a tool or utensil made from a stalk or handle-like structure, and eventually came to refer to the bony structure found in human and animal bodies. It is important to note that "scapulum" is the nominative singular form of the word in Latin, while "scapula" is the nominative plural form.
