The posterior belly arises from the medial surface of mastoid notch, a deep groove found on the mastoid process of temporal bone.

At its most basic level, muscle tissue is classified as either striated or non-striated/smooth based on the presence or absence of ‘striations’ (i.e. stripes/furrows) seen at a microscopic level; these are formed due to a particular arrangement of actin and myosin filaments within the myocyte (discussed below). Through these properties, the muscular system as a whole performs several important functions. These include the production of force and movement, support of body stature and position, stability of joints, production of body heat (to maintain normal body temperature), as well as, provision of form to the body. Obliquus capitis superior, that arises from the transverse process of atlas and inserts on the occipital bone, between the superior and inferior nuchal lines. The middle scalene muscle receives its nerve supply from the anterior rami of cervical spinal nerves C3-C8. Its blood supply stems from the ascending cervical branch of the inferior thyroid artery. Obliquus capitis inferior, that arises from the spinous process of axis and inserts on the transverse process of atlas.When the vertebral column is fixed, the muscle produces elevation of the 1st rib, which combined with the action of the external intercostals expands the antero-posterior diameter of the thoracic cage. This action is important during forced respiration. The intertransversarii colli are innervated by the anterior and posterior rami of cervical spinal nerves, and vascularized by the occipital, deep cervical and vertebral arteries.

The longus capitis is a long, flat muscle that arises from the anterior tubercles of transverse processes of vertebrae C3-C6 as four thin muscle strips. These muscle strips travel superiorly and medially to insert onto the inferior surface of the basilar part of the occipital bone. Femdomup contains materials for persons only 18+. If You have not reached this age, then we ask you to leave us. will tell you what to do. They can tell you the right place to get help if you need to see someone. The splenius cervicis arises from the spinous processes of vertebrae T3-T6 and inserts onto the transverse processes of vertebrae C1-C3.The mylohyoid is a sheet-like muscle that forms the majority of the floor of the mouth. The mylohyoid arises from the mylohyoid line on the inner surface of mandible, and inserts into the mylohyoid raphe and superior aspect of the body of hyoid bone. If the mandible is fixed, the mylohyoid elevates the hyoid bone and the floor of the mouth, which aids the act of deglutition by pressing the tongue against the hard palate.
