Feature 6 Concomitant Blood Vessels

Arteries and veins course along the nerve trunks to form neurovascular bundles to reach the muscle attachments. Acu-reflex points associated with neu-rovascular bundles tend to become sensitive more readily than do acu-reflex points associated only with cutaneous nerves, because the cutaneous nerves are not accompanied by concomitant blood vessels.

The deep radial nerve is a clear example of how an acu-reflex point is formed by concomitant blood vessels and nerves. At the lateral surface of the proximal portion of the forearm, the deep radial nerve is buried inside the intermuscular septum between the muscles of the brachioradialis and the extensor radialis longus. Both the deep radial nerve and the lateral antebrachial cutaneous nerves are located at a similar depth and have similar size, except that the h-'

Figure 7-5 The lateral antebrachial cutaneous nerve, a branch of the musculocutaneous nerve, forms an acu-reflex point (H9) at the lateral side of the elbow where it penetrates the fascia.

deep radial nerve is associated with rich concomitant blood vessels. The acu-reflex point H1 (deep radial) appearing in this location always becomes sensitive before the acu-reflex point H9 (lateral antebrachial cutaneous) associated with lateral antebrachial cutaneous nerve (see Fig. 7-4).

The physiologic role of blood vessels in forming acu-reflex points is unknown. More sensory receptors are presumably formed where the nerve innervates the smooth muscles of the blood vessel.
