Carpal tunnel syndrome (CTS) is caused by compression and subsequent irritation of the median nerve as it travels through the carpal tunnel and into the hand where it innervates the palm side of the second to fourth digits. (chiro-trust.org)
As stated last month, the median nerve is sometimes referred to as, "…the eye of the hand" since we rely so heavily on activities of daily living (ADLs) that require its health and function. (chiro-trust.org)
Since the median nerve originates from the C6-T1 (and a little from C5) nerve roots exiting the spine, it only makes sense that a pinched nerve in the neck can mimic a pinched nerve at the wrist. (chiro-trust.org)
In a few of us (only about 2%), there is a ligament just above the elbow that can entrap the median (as well as the ulnar) nerve, creating a pinch and subsequent numbness below that point, mimicking CTS. (chiro-trust.org)
The median nerve is more commonly entrapped by the pronator teres muscle just below the elbow, and treating this location can be highly rewarding when managing stubborn CTS cases. (chiro-trust.org)
The most distal point of median nerve compression is at the carpal tunnel. (chiro-trust.org)
Entrapments can be singular or multiple and when more than one "tunnel" compresses the median nerve, the term double or multiple crush is utilized. (chiro-trust.org)

Furthermore, lack of sensation over the radial dorsal hand may suggest an injury to the superficial radial nerve, which supplies the radial dorsal half of the hand. (basicmedicalkey.com)
For example, the radial nerve supplies sensation to the dorsum of the thumb, index, and middle finger, and also gives motor input to all the finger and wrist extensor tendons. (basicmedicalkey.com)
For the radial nerve, intact sensation over the dorsum thumb/index webspace indicates the integrity of the radial nerve, or more specifically, the radial sensory nerve ( Fig. 2 ). (basicmedicalkey.com)
The ability to extend the thumb when the hand lies flat on a table is powered by the extensor pollicis longus, which is supplied by the terminal branch of the radial nerve, or more specifically, the posterior interosseous branch of the radial nerve ( Fig. 3A -C). (basicmedicalkey.com)

First, there is strong evidence that the optic nerve head is an important site of injury. (touchophthalmology.com)
Characteristic optic nerve changes are observed in glaucoma and correlate with the pattern of visual field loss. (touchophthalmology.com)
The arcuate nature of many field defects observed in glaucoma also suggests the optic nerve head as the site of injury. (touchophthalmology.com)
In addition to such clinical evidence, recent basic science studies have pointed to the lamina cribrosa region of the optic nerve as a major site of injury in the disease. (touchophthalmology.com)
However, although there is strong evidence that the optic nerve head is an important site of injury in glaucoma, this does not preclude the possibility that glaucomatous neurodegeneration may be compounded by factors affecting other RGC compartments. (touchophthalmology.com)
