Mylohyoid: The mylohyoid muscle is a paired muscle running from the mandible to the hyoid bone. The mylohyoid is a broad, triangular shaped muscle. It forms the floor of the oral cavity and supports the floor of the mouth. Origin:...

Digastric: The digastric muscle is positioned in the neck, beneath the jaw. It occupies below the body of the mandible, and extends, in a curved form, from the mastoid process to the symphysis menti. This muscle assists in opening and...

Stylohyoid: The stylohyoid muscle is a thin muscular strip, that is positioned superiorly to the posterior belly of the digastric muscle. The stylohyoid muscle's innervation by the facial nerve, and functions to draw the hyoid bone backwards and elevate the...

Obliquus Capitis Superior: The obliquus capitis superior is located laterally in the suboccipital compartment. It is narrow below, wide and expanded above, and is lateral to the semispinalis capitis. It forms the superolateral border of the suboccipital triangle. Origin: Originates...

Obliquus Capitis Inferior: The obliquus capitis inferior is the most inferiorly positioned of the suboccipital muscles. It is situated under the deep cervical vein and comprises the inferior boarder of the suboccipital triangle.Additionally, it is the only capitis muscle that...

Rectus Capitis Posterior Minor: Rectus capitis posterior minor is a member of the suboccipital group of muscles along with rectus capitis posterior major, obliquus capitis superior, and obliquus capitis inferior.The rectus capitis posterior minor is the most medial of the...

Rectus Capitis Posterior Major: The rectus capitis posterior major is the larger of the rectus capitis muscles. It is located laterally to the rectus capitis posterior minor. It is also known as the Greater Posterior Rectus Capitis and comprises the...

Neck Muscles: The neck muscles are divided into four groups of muscles- Suboccipital MusclesSuprahyoid MusclesInfrahyoid MusclesScalene Muscles Suboccipital Muscles The suboccipital muscles are a group of four muscles located under the occipital bone. All the muscles are innervated by the...

C7 Spine: C7 has enlarged spinous process called vertebra prominence. It is the most prominent structure that can be palpated when we pass our finger downwards from the skull. Its spine is thick, long and nearly horizontal. It is not...

Cervical Spine (C3 to C6): The first, second and seventh are uniquely shaped, and C3 to C6 vertebra are often grouped together as similar to one another in form & function .C1 to C7 have a transverse foramen, vertebral artery...
