The term âgrowing painsâ first appeared in a book penned in 1823 by a French doctor, but since then physicians have realized that the peak of these pains, which is at around age 6, doesnât correspond to a period of rapid growth. (A quarter of a personâs total growth actually happens during puberty).
The Cervical Plexus. The cervical plexus is a network of nerve fibres that supplies innervation to some of the structures in the neck and trunk. It is located in the posterior triangle of the neck, halfway up the sternocleidomastoid muscle, and within the prevertebral layer of cervical fascia. The plexus is formed by the anterior rami (divisions) of cervical spinal nerves C1-C4.
The brachial plexus is the tangle of nerves that occurs in the shoulder when the cervical nerve roots exit from the spine. They form a âtangoâ (called a plexus) where these nerves join together and then separate into the final nerves that travel down the arm (the ulnar, median and radial nerves).
