Are you feeling weak, sluggish, overweight, or slow? ❌ Not sure if you should do more cardio or weightlifting? Eat more or fewer proteins, carbs, veggies?

This exercise loosens up tight muscles, relieves pain, and reduces spinal pressure. Keep your eyes facing forward the whole time. The vertebrae are formed from the sclerotomal portion of the somites (soma is Greek for "body"). The 42 pairs of somites are composed of the paraxial mesoderm of the embryo. [4]Sclerotomes, myotomes, symetotomes, and dermatomes are all subdivisions of somites. Somites give rise to the muscles, the vertebral column, and dermatomes (the sensory supply from a given spinal cord nerve).Lee S, et al. (2017). Effects of the cervical flexion angle during smartphone use on muscle fatigue and pain in the cervical erector spinae and upper trapezius in normal adults in their 20s. The digastric muscle is a small muscle situated below the mandible, that extends from the mastoid process of temporal bone to the chin. The muscle is composed of a posterior and an anterior belly, connected by an intermediate tendon, which represents their common insertion point.

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.All four of the suboccipital muscles are innervated by the suboccipital nerve (C1), and vascularized by the vertebral artery and the deep descending branches of the occipital artery. The suboccipital triangle forms from a group of muscles located at the base of the skull (rectus capitis posterior major and minor, and the obliquus capitis superior and inferior). A myodural bridge exists between the rectus capitus posterior minor muscle and the intracranial dura. A cervicogenic headache can result when this bridge is stretched or inflamed from cervical spine joint dysfunction or excessive tightness of the suboccipital triangle muscles. Spinal manipulation, soft tissue intervention, and therapeutic exercise may help treat and prevent the future occurrence of a myodural bridge, which will cause headaches. [16] The suboccipital muscles are four small muscles found in the suboccipital region, deep to the semispinalis muscles. These are: The posterior scalene is the smallest and most posterior of the scalene muscles that arises from the posterior tubercles of transverse processes of cervical vertebrae C4-C6. It then extends posterolaterally and inserts into the external surface of the second rib. Semispinalis capitis, that arises from the articular processes of vertebrae C4-C7 and transverse processes of vertebrae T1-T6. It then courses upwards to insert between the superior and inferior nuchal lines of the occipital bone.

The intermediate part arises from the anterior surface of bodies of vertebrae C5-T3 and inserts into the anterior surface of bodies of vertebrae C2-C4.

These are examples of compression injuries, resulting in a compromised blood supply to the affected nerve. The result of such injury is often paresthesia, a condition in which the fine touch sensation is compromised or lost, but the pain and temperature sensation is normal. The pain sensation may be increased (hyperalgesia) because the axons supplying pain are damaged and, therefore, irritable. This dichotomy occurs because the fine-touch fibers are the largest and have the highest oxygen demand. The fibers for pain and temperature are much smaller and can survive when the fine-touch fibers are damaged or dead. However, the pain and temperature fibers can be damaged, producing severe chronic pain. Vertebrae C3 through C7 are known as "typical" cervical vertebrae. The primary motion of the upper portion of the lower cervical unit (C2-C4) is rotation. The primary motion of the lower portion of the lower cervical unit is side-bending.The description of all spinal and vertebral movements is relative to motions of their anterior and superior surfaces. [1] The digastric muscle has dual innervation. The anterior belly is innervated by the nerve to mylohyoid, a branch of the inferior alveolar nerve, while the posterior belly receives innervation from the digastric branch of the facial nerve. The blood supply for the digastric muscle is derived from the submental branch of the facial artery, and posterior auricular and occipital arteries.
