30 paź 2023 · Additionally, the suboccipital nerve innervates the semispinalis capitis muscle (that forms the roof of the suboccipital triangle) and the rectus capitis posterior minor muscle. In some cases, the suboccipital nerve can give rise to a cutaneous branch that joins the occipital nerves in the innervation of the scalp.
23 wrz 2023 · The suboccipital nerve, also known as the posterior ramus of the first cervical spinal nerve (C1), is a nerve that primarily provides motor innervation to the muscles in the suboccipital triangle of the neck. It also contributes to some sensory innervation in the occipital region. Structure Type: The suboccipital nerve is mainly a motor nerve,
The posterior ramus, or suboccipital nerve innervates muscles of the suboccipital triangle (rectus capitis posterior major and minor, obliquus capitis superior and inferior) and semispinalis capitis.
31 paź 2022 · Nerves of the Posterior Head and Neck Region. This illustration shows the suboccipital nerve, greater occipital nerve, cutaneous branch suboccipital nerve, lesser occipital nerve, and third occipital nerve. Illustration by E Gregory
30 sty 2024 · The suboccipital nerve innervates the 3 muscles bordering the suboccipital triangle and the rectus capitis posterior minor. Collectively, the suboccipital muscles function as the head's postural muscles, assisting in head extension and rotation.
A filament from the branch to the Obliquus inferior joins the posterior division of the second cervical nerve. The nerve occasionally gives off a cutaneous branch which accompanies the occipital artery to the scalp, and communicates with the greater and lesser occipital nerves.
The suboccipital nerve (first cervical dorsal ramus) is the dorsal primary ramus of the first cervical nerve (C1). It exits the spinal cord between the skull and the first cervical vertebra, the atlas. [1]
