The lesser occipital nerve (or small occipital nerve [1]) is a cutaneous spinal nerve of the cervical plexus. [2] It arises from second cervical (spinal) nerve (C2) (along with the greater occipital nerve).
The occipitalis muscle (occipital belly) is a muscle which covers parts of the skull. Some sources consider the occipital muscle to be a distinct muscle. However, Terminologia Anatomica currently classifies it as part of the occipitofrontalis muscle along with the frontalis muscle. The occipitalis muscle is thin and quadrilateral in form.
The occipitalis minor is a muscle in the back of the head which normally joins to the auricular muscles of the ear. This muscle is very sporadic in frequency—always present in Malays, present in 56% of Africans, 50% of Japanese, and 36% of Europeans, and nonexistent in the Khoikhoi people of southwestern Africa and in Melanesians.

The greater occipital nerve is a nerve of the head. It is a spinal nerve, specifically the medial branch of the dorsal primary ramus of cervical spinal nerve 2.It arises from between the first and second cervical vertebrae, ascends, and then passes through the semispinalis muscle.
Occipital neuralgia is caused by damage to the occipital nerves, which can arise from trauma (usually concussive or cervical), physical stress on the nerve, repetitive neck contraction, flexion or extension, and/or as a result of medical complications (such as osteochondroma, a benign bone tumour).

The rectus capitis posterior minor (or rectus capitis posticus minor [citation needed]) is a muscle in the upper back part of the neck. It is one of the suboccipital muscles . Its inferior attachment is at the posterior arch of atlas ; its superior attachment is onto the occipital bone at and below the inferior nuchal line .
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.
