MUSCULUS TRAPEZIUS Meaning and
Definition
-
The Musculus Trapezius, commonly known as the trapezius muscle, is a large, paired, and flat triangular muscle located on the upper back and neck region of the human body. It is named after its trapezoidal shape, with a broad base at the top of the spine and a narrow apex pointing towards the shoulder blades.
The trapezius muscle is one of the major muscles involved in movements of the shoulder and neck. It originates from the base of the skull, the spinous processes of the cervical and thoracic vertebrae, and the ligamentum nuchae, and it inserts into the spine of the scapula, the acromion, and the lateral third of the clavicle. The muscle is divided into three distinct portions: the upper, middle, and lower fibers.
The primary functions of the trapezius muscle include elevation, retraction, and depression of the scapula, as well as extension and lateral flexion of the neck. It is responsible for movements such as shrugging the shoulders, maintaining posture, and rotating and tilting the head. It also stabilizes the scapula during various upper limb movements.
The trapezius muscle is innervated by the accessory nerve (cranial nerve XI) and receives a blood supply from the transverse cervical artery, as well as other contributing vessels. It is often subjected to tension and stress, leading to common complaints such as muscle tightness, pain, and stiffness. Exercises targeting the trapezius muscle, such as shoulder shrugs, rows, and head tilts, can be performed to improve strength and flexibility.

Etymology of MUSCULUS TRAPEZIUS
The word "musculus trapezius" is derived from Latin.
The term "musculus" translates to "muscle" in English and originates from the Latin word "mūsculus", which means "little mouse" due to the similarity in appearance.
The word "trapezius" comes from the Greek word "trapezion", meaning "irregular quadrilateral". This is because the trapezius muscle is a large, flat, triangular-shaped muscle located on the upper back between the neck and the shoulders. The Greek word "trapezion" was later adapted into the Latin term "trapezius".
