  2. Occipital neuralgia - Wikipedia

    en.wikipedia.org/wiki/Occipital_neuralgia

    Patients presenting with a headache originating at the posterior skull base should be evaluated for ON. This condition typically presents as a paroxysmal, lancinating or stabbing pain lasting from seconds to minutes, and therefore a continuous, aching pain likely indicates a different diagnosis. Bilateral symptoms are present in one-third of cases.

  3. Nuchal ligament - Wikipedia

    en.wikipedia.org/wiki/Nuchal_ligament

    From the anterior border of the nuchal ligament, a fibrous lamina is given off. This is attached to the posterior tubercle of the atlas, and to the spinous processes of the cervical vertebrae, and forms a septum between the muscles on either side of the neck. The trapezius and splenius capitis muscle attach to the nuchal ligament.

  4. Posterior longitudinal ligament - Wikipedia

    en.wikipedia.org/wiki/Posterior_longitudinal...

    The posterior longitudinal ligament contains a higher density of nociceptors than many ligaments, so can cause back pain. [1] It may ossify, particularly around cervical vertebrae. [1] The posterior longitudinal ligament has a high density of vasomotor fibres, allowing for increased blood flow to respond to damage to the ligament. [1]

  5. External occipital protuberance - Wikipedia

    en.wikipedia.org/wiki/External_occipital...

    The nuchal ligament and trapezius muscle attach to it. The inion (ἰνίον, iníon, Greek for the occipital bone) is used as a landmark in the 10-20 system in electroencephalography (EEG) recording. Extending laterally from it on either side is the superior nuchal line, and above it is the faintly marked highest nuchal line.

  6. Greater occipital nerve - Wikipedia

    en.wikipedia.org/wiki/Greater_occipital_nerve

    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.

  7. Nuchal lines - Wikipedia

    en.wikipedia.org/wiki/Nuchal_lines

    The nuchal lines are four curved lines on the external surface of the occipital bone: The upper, often faintly marked, is named the highest nuchal line, but is sometimes referred to as the Mempin line or linea suprema, and it attaches to the epicranial aponeurosis. Below the highest nuchal line is the superior nuchal line.

  8. Posterior triangle of the neck - Wikipedia

    en.wikipedia.org/wiki/Posterior_triangle_of_the_neck

    The posterior triangle has the following boundaries: [1] Apex: Union of the sternocleidomastoid and the trapezius muscles at the superior nuchal line of the occipital bone. Anteriorly: Posterior border of the sternocleidomastoideus. Posteriorly: Anterior border of the trapezius. Inferiorly: Middle one third of the clavicle

  9. Rectus capitis posterior minor muscle - Wikipedia

    en.wikipedia.org/wiki/Rectus_capitis_posterior...

    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.
