Rectus capitis posterior minor muscle
Rectus Capitis Posterior Minor Muscle[edit | edit source]
The Rectus Capitis Posterior Minor muscle is a small muscle located in the posterior region of the neck. It is one of the suboccipital muscles, a group of four muscles that play a crucial role in the movement and stabilization of the head.
Anatomy[edit | edit source]
The Rectus Capitis Posterior Minor muscle originates from the posterior tubercle of the atlas (C1 vertebra) and inserts into the medial part of the inferior nuchal line of the occipital bone. It lies deep to the Rectus Capitis Posterior Major muscle and is situated between the obliquus capitis superior and inferior muscles.
Function[edit | edit source]
The main function of the Rectus Capitis Posterior Minor muscle is to extend and rotate the head. It works in conjunction with the other suboccipital muscles to maintain proper posture and stabilize the head on the neck. Additionally, it assists in the movement of the head during flexion and lateral bending.
Clinical Significance[edit | edit source]
Due to its close proximity to important structures in the neck, the Rectus Capitis Posterior Minor muscle can be involved in certain clinical conditions. Trigger points in this muscle can cause referred pain to the occipital region, leading to headaches and neck pain. These trigger points can be treated with manual therapy techniques such as trigger point release or dry needling.
Related Muscles[edit | edit source]
The Rectus Capitis Posterior Minor muscle is part of the suboccipital group, which also includes the Rectus Capitis Posterior Major, Obliquus Capitis Superior, and Obliquus Capitis Inferior muscles. These muscles work together to control the movement and stability of the head.
