The splenius muscles are: Splenius capitis muscle; Splenius cervicis muscle; Their origins are in the upper thoracic and lower cervical spinous processes. Their actions are to extend and ipsilaterally rotate the head and neck.
The splenius capitis (/ ˈ s p l iː n i ə s ˈ k æ p ɪ t ɪ s /) (from Greek splēníon 'bandage' and Latin caput 'head' [1] [2]) is a broad, straplike muscle in the back of the neck.

The semispinalis capitis (complexus) is situated at the upper and back part of the neck, deep to the splenius muscles, and medial to the longissimus cervicis and longissimus capitis. It arises by a series of tendons from the tips of the transverse processes of the upper six or seven thoracic and the seventh cervical vertebrae , and from the ...
To it is attached, the splenius capitis muscle, the trapezius muscle, [1] and the occipitalis. [2] From the external occipital protuberance a ridge or crest, the external occipital crest also called the median nuchal line, often faintly marked, descends to the foramen magnum, and affords attachment to the nuchal ligament.
Epaxial muscles include other (dorsal) muscles associated with the vertebrae, ribs, and base of the skull. In humans, the erector spinae, the transversospinales (including the multifidus, semispinalis and rotatores), the splenius and suboccipital muscles are the only epaxial muscles. Hypaxial and epaxial muscles develop directly from somitic ...
In sheep and cattle, it is known as the paxwax. [4] It relieves the animal of the weight of its head. The nuchal ligament is unusual in being a ligament containing more elastin as well as collagen, allowing for stretch and recovery to its original form. [5]
