Splenius Capitis Muscle Laterally
Splenius Capitis Muscle is a broad strap like muscle in the back of head.. It starts from the three points which are as follows. Lower half of Nuchal Ligament (ligament at the back of Neck) Spinous Process (serves attachments of muscles and ligaments) of Seventh Cervical Vertebrae Upper three or four Thoracic Vertebrae. The fibers of this muscle also end in three points given below. Under cover of Sternocleidomastoideus (paired muscle in superficial layer of the Anterior Neck) Mastoid Process of Temporal Bone Below Superior Nuchal Line, the rough surface of Occipital Bone. This muscle is formed from the base of the posterior triangle of Neck.
Splenius Capitis Muscle receives its innervations from the Dorsal Rami of Cervical Spinal Nerves C3, 4, 5, 6.
The blood to the muscle is supplied from the branches of the Occipital Artery which itself is a branch of External Carotid Artery.
Splenius Capitis plays a prime function in the extension of Head. The muscle also allows the flexion and rotation of Cervical Spine.
Damage to this muscle can result in neck pain, headaches, facial pain and shoulder pain. These pains can be relieved by stretching, physical therapy and ice or heat massage.ANATOMY
