Where does the nuchal ligament start and end?
The nuchal ligament extends from the external occipital protuberance on the skull and median nuchal line to the spinous process of the seventh cervical vertebra in the lower part of the neck.
Can you feel ligamentum nuchae?
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.
What muscles attach to nuchal ligament?
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 is the function of the ligamentum nuchae?
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.
Where does the nuchal ligament 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 muscle originates from the ligamentum nuchae?
The ligamentum nuchae is formed primarily from the aponeurotic attachments of the adjacent and subjacent musculature. From superficial to deep, these muscles are the trapezius; rhomboideus minor; splenius capitis; and the serratus posterior superior.
What type of tissue is ligamentum nuchae?
Elastic Connective TissueElastic 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 is nuchal ligament calcification?
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.
Where does the nuchal ligament attach to?
The nuchal ligament forms a broad attachment to the dorsal apexes of the spinous processes of the withers and continues caudally as the supraspinous ligament.
Do cervical ligaments heal?
Neck sprains or strains will heal gradually with the appropriate treatment protocols. Your doctor may recommend wearing a soft collar to help support the head and relieve pressure on the ligaments in the neck.
What type of tissue is ligamentum nuchae?
Elastic Connective TissueElastic 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 is the ligamentum nuchae?
The ligamentum nuchae is a large median ligament composed of tendons and fascia located between the posterior muscles of the neck. It covers the spines of C1 to C6 vertebrae. It is a superior and posterior extension of the supraspinous ligament.
Which vertebrae are covered by the supraspinous ligament?
It covers the spines of C1 to C6 vertebrae. It is a superior and posterior extension of the supraspinous ligament. It rises from the spinous process of C7 to the inion of the occipital bone, attaching all the posterior tips of the spinous processes in between. It is thick and strong, limiting hyperflexion of the neck.
What membranes are the medial septum in?
The medial septum blends into the posterior atlanto-occipital membrane and the posterior atlanto-axial membrane (upper portion of the ligamentum flavum between C1 and C2). It is attached to the posterior spinal dura along these membranes. ossification of ligamentum nuchae.
Where does the medial septum go?
The medial septum runs deep into the vertebral column. It reaches depths as far as the ligamentum flavum . The medial septum blends into the posterior atlanto-occipital membrane and the posterior atlanto-axial membrane (upper portion of the ligamentum flavum between C1 and C2). It is attached to the posterior spinal dura along these membranes.
What is the superior portion of the C7?
It extends from the occipital protuberance to the spinous process of the C7 vertebra. The superior portion consists of medial fibers from the cervical trapezius. The inferior portion consists of interweaving tendons from splenius capitis and rhomboid minor.
Which septum isolates the semispinalis capitis?
The medial septum isolates the semispinalis capitis ventrally and laterally. Thus, the semispinalis cervicis, multifidus and opposite semispinalis capitis remain separate. The medial septum runs deep into the vertebral column. It reaches depths as far as the ligamentum flavum .
Where is the nuchal ligament located?
The nuchal ligament is a ligament at the back of the neck that is continuous with the supraspinous ligament .
What is the function of the nuchal ligament?
In some four-legged animals, particularly ungulates, the nuchal ligament serves to sustain the weight of the head.
What ligaments do dogs have?
This ligament is analogous in function (but different in exact structural detail) to the nuchal ligament found in ungulates. This ligament allows dogs to carry their heads while running long distances, such as while following scent trails with their nose to the ground, without expending much energy.
Which ligament attaches to the posterior tubercle of the Atlas?
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.
Which vertebrae are connected to the back of the neck?
All dogs (and all living Canidae - wolves, foxes, and wild dogs) possess a similar ligament connecting the spinous process of their first thoracic (or chest) vertebrae to the back of the axis bone (second cervical or neck bone), which supports the weight of the head without active muscle exertion, thus saving energy.
Do all animals have a nuchal ligament?
In most other mammals, including the great apes, the nuchal ligament is absent or present only as a thin fascia. As it is required for running, not all animals have one.
Where is the nuchal ligament located?
Ligamentum Nuchae. Also known as the nuchal ligament, this ligament is located at the back of your neck. It merges with the supraspinous ligament, which as we’ve discussed, is that long, strong cord that connects the tips of most (i.e. the lumbar and thoracic) of your spinous processes.
Where is the ligament flavum located?
It is located between the laminae of the vertebra. At each vertebral level, fibers originate from a superior lamina (the term superior refers to a location above, relatively speaking) and connect to the inferior lamina (i.e. the lamina just below). The ligamentum flavum limits spinal flexion (bending forward), especially abrupt flexion. This function enables the ligamentum flavum to protect your discs from injury.
What ligaments provide stability to the column?
Spinal ligaments also provide stability to the column. They do this by limiting the degree of movement in the direction opposite their location. For example, your anterior longitudinal ligament (see below for details) is located in front of your vertebral bodies. When you arch back, it prevents you from going too far.
What is ligamentum flavum?
The phrase ligamentum flavum means "yellow ligament". The ligamentum flavum is made of a (pale) yellow-colored elastic tissue. This tissue is similar to the type of connective tissue that comprises the other spinal ligaments, except there’s a degree of elasticity to it.
Where does the interspinous ligament connect to the spinous process?
The interspinous ligaments connect the whole of each spinous process vertically. The interspinous ligament starts at the root of the spinous process, where it emerges from the ring of bone located at the back of the body of its respective vertebra, and extends all the way out to the tip.
Which ligaments are more fibrous?
In the thoracic (mid-back) area, the intertransverse ligaments are tougher and more fibrous. Now you know your ligament ABCs. These are the spinal ligaments that affect all or at least large portions of the spine. Other spinal ligaments are specific to an area such as the neck or the sacrum and sacroiliac joints.
Which ligaments limit forward bending?
The supraspinous and interspinous ligaments both limit flexion (forward bending). Located in back, the supraspinous ligament is a strong rope like tissue that connects the tips of the spinous processes from your sacrum up to C7 (otherwise known as the base of the neck).
