One of the 5 main muscles of movement.

Keeping it simple: trapezius.

Anatomy in detail.

TRAPEZIUS

The left and right trapezius muscles form the most superficial muscle layer from mid-back to the base of the skull.

Thin muscles, sculpted down the neck and towards the shoulders, attaching to both scapula (shoulder blade) and clavicle (collar bone) of each arm.

The trapezii (plural) meet on the median plane where they attach to the nuchal and supraspinous ligaments and the spinous processes of the 7th cervical to 12th thoracic vertebrae.

the trapezius muscles, connecting the base-line muscles to the head and arms. From the back of your head, down the back and sides of your neck towards your shoulders and then extending down to a point at mid-back level.
Like a kite on the back. From the level of the bottom ribs, starting as point each trapezius extends up and out towards the shoulders like two triangles.  The widest part across the top of the neck/shoulders before narrowing again towards the head like another two triangles on top of the bottom ones.

Wikipedia: Trapezius: from Late Latin trapezium, from Greek τραπέζιον (trapézion), literally "a little table", a diminutive of τράπεζα (trápeza), "a table", itself from τετράς (tetrás), "four" + πέζα (péza), "a foot; end, border, edge"

The trapezii should be free to extend in all directions without pain or restriction, supporting the head and arms through their full range of movement, connecting the upper body to Base-Line support.

Trapezius keeping it simple

trapezius-muscles in three sections the upper trapezius triangles, the middle trapezius horizontal strips across the shoulders, and the lower trapezius triangles ending as as point at the base of the ribs.

Current descriptions split the trapezius into 3 functional sections, based on the direction of the muscle fibres.

Upper trapezius

Middle trapezius

Lower trapezius

Upper trapezius

a.k.a. superior (i.e. higher than the other sections) or descending (i.e. the muscle fibres descend) trapezius.

Attaches to:

Middle trapezius

a.k.a. transverse (i.e. the muscle fibres run approximately horizontally) trapezius.

Attaches to:

Lower trapezius

a.k.a. inferior (i.e. lower than the other sections) or ascending (i.e. the muscle fibres ascend) trapezius.

Attaches to:

Showing the nuchal ligament like a triangle of connective tissue extending from the midline between the trapezii  into the neck to the cervical vertebrae.  Also the clavicle and scapula bones and the thoracic vertebrae. trapezius muscle and its attachments, seen from the side. The curve in the trapezius from the base of the skull as it goes down the back of the neck is pronounced as the sides of the each trapezius fan out towards the shoulders. Like a curved blanket over the neck and upper back.
Bones and ligaments of the neck and upper back where the trapezius muscles attach

Between the 6th cervical and 3rd thoracic vertebrae (the base of the nuchal ligament and start of the supraspinous ligament) the trapezius muscles are connected to the midline by a broad semi-elliptical aponeurosis (thin sheet of strong connective tissue), forming a tendinous ellipse between the shoulder blades.

The trapezius muscles should be free the extend in all directions.

 OPTIMISING THE USE OF YOUR MUSCLES = BETTER HEALTH.

ALWAYS START FROM BASE-LINE, ALWAYS GO BACK TO BASE-LINE.
