What muscles form the suboccipital triangle?
The right suboccipital region has been exposed and shows the muscles that form the suboccipital triangle: obliquus capitis inferior, obliquus capitis superior, and rectus capitis posterior major.
What are the 4 suboccipital muscles?
The suboccipital muscles are a group of four muscles located inferior to the occipital bone. These four muscles include the rectus capitis posterior major, rectus capitis posterior minor, obliquus capitis superior, and obliquus capitis inferior.
What do the suboccipital triangle muscles do?
The suboccipital muscle group contains four paired muscles, three of which pairs belong to the suboccipital triangle. These muscles all lie below the occipital bone and are responsible for postural support of the head, as well as extension, lateral flexion and rotation.
How do you remember suboccipital muscles?
Suboccipital muscles-think head -rectus and oblique-both sub occipital nerve-extension rotation and lateral flexion of cervical spine. Rectus capitiis obliques-major and minor (majors are straight!)- major is from axis not atlas despite thought.
Where are suboccipital muscles?
occipital bone
The suboccipital region is a muscle compartment, located inferior to the external occipital protuberance and the inferior nuchal line. These are anatomical landmarks on the occipital bone of the skull.
What Innervates the suboccipital triangle?
The suboccipital nerve innervates the following suboccipital muscles: The rectus capitis posterior minor muscle. The rectus capitis posterior major muscle (the superomedial border of the suboccipital triangle) The obliquus capitis superior (the superolateral border of the suboccipital triangle)
What Innervates suboccipital triangle?
Why do suboccipital muscles get tight?
The suboccipital muscles commonly become tense and tender due to factors such as eye strain, wearing new eyeglasses, poor ergonomics at a computer workstation, grinding the teeth, slouching posture, and trauma (such as a whiplash injury).
What nerve Innervates the suboccipital triangle?
The suboccipital nerve carries mainly motor fibers. The prime function of this nerve is to provide motor innervation for the suboccipital muscle group….Suboccipital nerve.
| Origin | First cervical nerve (C1) |
|---|---|
| Branches | Muscular branches |
What muscles does suboccipital nerve supply?
The suboccipital nerve innervates the following suboccipital muscles:
- The rectus capitis posterior minor muscle.
- The rectus capitis posterior major muscle (the superomedial border of the suboccipital triangle)
- The obliquus capitis superior (the superolateral border of the suboccipital triangle)
What causes tight suboccipital muscles?
Where is the suboccipital triangle located?
The suboccipital triangle is contained within a space bordered by muscles and ligaments deep to the nuchal region (posterior neck). The suboccipital triangle has three boundaries contained between a floor and roof.
What are the suboccipital muscles?
The suboccipital muscles are a group of four muscles situated underneath the occipital bone. All the muscles in this group are innervated by the suboccipital nerve.
Where is the suboccipital nerve located?
All the muscles in this group are innervated by the suboccipital nerve. They are located within the suboccipital compartment of the neck; deep to the sternocleidomastoid, trapezius, splenius and semispinalis muscles.
What is suboccipital syndrome?
Suboccipital syndrome is a disorder that can occur due to shortening of the muscles in the suboccipital triangle or spasms of these muscles. This may be due to poor posture or due to the effects of underlying spinal degeneration.
