The splenius capitis muscle is a deep, thin, broad muscle located at the back of the neck. This muscle originates from several different locations in the neck and upper back areas of the body. These locations include: Bottom of the nuchal ligament: the ligament located at the back, base of the skull.

What does the Semispinalis capitis muscle do?

The semispinalis capitis is a long, thin muscle that is located at the back of the neck, on both sides of the spinal column. This muscle has several different functions, which include: Neck extension: bending the neck backward, such as when you look at the ceiling above your head.

Thereof, what does the Splenius capitis muscle do?

Function. The splenius capitis muscle is a prime mover for head extension. The splenius capitis can also allow lateral flexion and rotation of the cervical spine.

Why does my Splenius capitis hurt?

Splenius capitis syndrome is a condition in which the splenius capitis muscle becomes injured, causing pain and other symptoms throughout the head, neck, and upper extremities. Causes of splenius capitis syndrome include car accidents, sports collisions, falls, direct trauma, and poor posture.

In this regard, where does Splenius capitis attach?

The splenius capitis is a deep muscle of the neck. It originates from the lower half of the nuchal ligament and the spinous processes of the 7th cervical vertebra and the superior 3 thoracic vertebrae. It inserts onto the mastoid process of the temporal bone. It acts to laterally flex and rotate the neck.

What are the Suboccipital muscles?

Anatomical terms of muscle

The suboccipital muscles are a group of muscles defined by their location to the occiput. Suboccipital muscles are located below the occipital bone. These are four paired muscles on the underside of the occipital bone; the two straight muscles (rectus) and the two oblique muscles (obliquus).

What is the origin of the trapezius?

The trapezius has multiple origin and insertion points—it’s simply too big not to. It originates on the occipital bone, the ligamentum nuchae, and the spinous processes of T01-T12. The trapezius inserts on the lateral third of the clavicle, as well as the acromion and scapular spine of the scapula.

What causes Vertex pain?

Top of the Head – This type of headache is usually caused by disorders of the liver. It is also called a vertex headache. Back of the Head – The back of the head is also called the occipital area. Occipital headaches that are acute are usually caused by the invasion of external factors, such as Wind, Cold and Dampness.

How many Sternocleidomastoid muscles are there?

The sternocleidomastoid muscle (SCM) is one of more than 20 pairs of muscles that act on the neck. SCM has a dual-innervation and multiple functions.

Where is the Semispinalis Thoracis?

Semispinalis thoracis muscle. Semispinalis are a group of back muscles that together with the rotatores and multifidus comprise the spinotransverse group of deep back muscles. Semispinalis group is found lying on either side of the vertebral column spanning from the skull as far as to the vertebra T10.

Where do lats attach?

As the muscle fibers of the lats extend from the origin to the insertion point (the insertion for the lats is located on the inner aspect of your upper arm bone, just below the shoulder joint) they taper into a point.

What are the neck muscles?

Neck muscles help support the cervical spine and contribute to movements of the head, neck, upper back, and shoulders. Here are some of the key muscles attached to the cervical spine:

  • Levator scapulae.
  • Sternocleidomastoid (SCM).
  • Trapezius.
  • Erector spinae.
  • Deep cervical flexors.
  • Suboccipitals.

Where is the Semispinalis capitis?

The semispinalis capitis inserts or attaches to the occipital bone, which is the bone located at the back base of the skull. This muscle attaches to the occipital bone between the superior and inferior nuchal lines, which are ridges located on the occipital bone.

What are the Splenius muscles?

The splenius muscle of the head and the splenius muscle of the neck work together so that the neck and the head can extend (tilt backward) and rotate. The splenius muscle of the head, also known as the splenius capitis, is a broad muscle located at the back of the neck. It is attached to the base of the skull.

One may also ask, is the Splenius capitis superficial or deep?

The superficial muscles are also known as the spinotransversales. There are two muscles in this group – splenius capitis and splenius cervicis. They are both associated with movements of the head and neck. They are located on the posterolateral aspect of the neck, covering the deeper neck muscles.

What are trap muscles?

The trapezius muscle is a postural and active movement muscle, used to tilt and turn the head and neck, shrug, steady the shoulders, and twist the arms. The trapezius elevates, depresses, rotates, and retracts the scapula, or shoulder blade. Innervation of the trapezius is derived from the spinal accessory nerve.

What causes tight trapezius muscles?

Causes of trapezius pain

  • Overuse: Pain in the trapezius often develops due to overuse.
  • Stress: It is common for people to tense the muscles of the shoulder and neck when they feel stressed.
  • Poor posture: Prolonged poor posture can place added stress on the trapezius.

What is in the Suboccipital triangle?

Contents. The suboccipital triangle contains the vertebral artery, suboccipital nerve (C1), and suboccipital venous plexus. The suboccipital nerve is the posterior ramus of C1 spinal nerve. It courses between the posterior arch of atlas and the vertebral artery to innervate the four suboccipital muscles.

What causes levator scapulae pain?

There are many causes of levator scapulae syndrome. Probably the most common cause of this condition is sitting with incorrect posture for long periods of time, such as when a person sits at a work desk with their upper back, shoulders, and neck hunched over. Symptoms of levator scapulae syndrome include: Pain.

How do you stretch your Splenius capitis?
