The rhomboideus is a thick, large muscle below the trapezius muscles. It extends from the vertebral border of the scapula to the mid-dorsal line. Its origin is from the neural spines of the first four thoracic vertebrae, and its insertion is at the vertebral border of the scapula. Its action is to draw the scapula to the dorsal.
The trapezius muscle (pl.: trapezii) is a surface muscle of back, shown in red above and below. Details. Origin. Medial one-third of superior nuchal line, external occipital protuberance, spinous processes of vertebrae C7-T12, Nuchal ligament [1] Insertion. Posterior border of the lateral one-third of the clavicle, acromion process, and spine ...
v. t. e. The accessory nerve, also known as the eleventh cranial nerve, cranial nerve XI, or simply CN XI, is a cranial nerve that supplies the sternocleidomastoid and trapezius muscles. It is classified as the eleventh of twelve pairs of cranial nerves because part of it was formerly believed to originate in the brain.
The root of the spine of the scapula is the most medial part of the scapular spine. It is termed "triangular area of the spine of scapula", based on its triangular shape giving it distinguishable visible shape on x-ray images. [1] The root of the spine is on a level with the tip of the spinous process of the third thoracic vertebra.

Cats can use a range of communication methods, including vocal, visual, tactile and olfactory communication. Up to 21 different cat vocalizations have been observed. [ 3 ] They use visual signals, or body language, to express emotions like relaxation, fear, and aggression. Cats use several types of tactile behaviors to communicate, such as ...
The platysma muscle is a broad sheet of muscle arising from the fascia covering the upper parts of the pectoralis major muscle and deltoid muscle. Its fibers cross the clavicle, and proceed obliquely upward and medially along the side of the neck. This leaves the inferior part of the neck in the midline deficient of significant muscle cover.
The levator scapulae is a slender [ 1 ]: 910 skeletal muscle situated at the back and side of the neck. It originates from the transverse processes of the four uppermost cervical vertebrae; it inserts onto the upper portion of the medial border of the scapula. It is innervated by the cervical nerves C3-C4, and frequently also by the dorsal ...
