Which muscles attach to the ligamentum nuchae?

Which muscles attach to the ligamentum nuchae?

The trapezius and splenius capitis muscle attach to the nuchal ligament.

Where does the ligamentum nuchae attach?

Attachments. Extends from the external occipital protuberance on the skull and median nuchal line, to the spinous process of C7. The deep fibers of the ligament attach to the external occipital crest, the posterior tubercle of the atlas, and to the medial surface of the bifid processes of the other cervical vertebrae.

What does the ligamentum nuchae connect?

The ligamentum nuchae directly attaches to the spinal dura, as does the ligamentum flavum, to a lesser degree. The upper cervical nerves serve the sensory innervation of both the cervical spinal dura and the cranial dura in the posterior cranial fossa.

What are the two parts of ligamentum nuchae?

The ligamentum nuchae consists of the dorsal raphe and medial septal parts. The dorsal raphe attaches to muscles while the medial septum does not.

What are the nuchal muscles?

a) In the nuchal region, the superficial intrinsic layer consists of the splenius muscles. They lie on both the lateral and posterior aspects of the neck. There are two splenius muscles: splenius cervicis and splenius capitis.

What type of connective tissue is ligamentum nuchae?

Elastic Connective Tissue
Elastic Connective Tissue – the ligamentum nuchae is an example of elastic connective tissue. The ligamentum nuchae is a ligament at the back of the neck. It is dense regular connective tissue with both collagen and elastic fibers.

What type of tissue is ligamentum nuchae?

Can you feel your nuchal ligament?

You should be able to easily feel the nuchal ligament in your neck (I could not due to the restrictions in surrounding tissues.) Extend your head backward and press your fingers on the midline of the back of your neck.

Is ligamentum nuchae a ligament?

Here’s the nuchal ligament, also called the ligamentum nuchae. It’s a sheet of strong fibrous tissue that extends from the spinous process of the first thoracic vertebra, to the external occipital protuberance. The nuchal ligament limits forward flexion of the head and the cervical spine.

How does nuchal ligament work?

The nuchal ligament is a triangular fibrous membrane, which extends from the external occipital protuberance to the spinous process of the 7th cervical vertebra4,12). It maintains the lordotic alignment and limits the movements of cervical spine6,17).

Can you feel ligamentum nuchae?

What is calcification of the ligamentum nuchae?

Calcification of the alar ligament is a rare condition, which usually develops in the elderly and tends to occur following traumatic injury or as a consequence of inflammatory disease. In crowned dens syndrome, calcium pyrophosphate dehydrate crystals deposit on the atlantoaxial joint.

What movement does the nuchal ligament limit?

The nuchal ligament limits forward flexion of the head and the cervical spine. It also serves as the attachment for some major muscles.

What muscles attach C7?

12 The splenius capitis muscle, semi- spinalis cervicis muscle, and multifidus muscle, as well as the trapezius and rhomboid minor muscles, attach to the C7 spinous process and connect to the scapula.

What muscles attach C5?

Muscles of the Spinal Column

Why is C7 so important?

The body of C7 supports the collective weight of the head and neck. Lateral Facets, allow C7’s body to form joints with the C6 vertebra above it and the T1 below it. The facets surrounding the body provide both stability and flexibility to the neck.

What muscles attach C2?

suboccipital muscle group. rectus capitis posterior major muscle. rectus capitis posterior minor muscle. obliquus capitis superior muscle. obliquus capitis inferior muscle.
