thenar eminence การใช้

It also supplies the muscles of the thenar eminence by a recurrent thenar branch.
Characteristic signs include pain, swelling, and ecchymosis around the thenar eminence, and especially over the MCP joint of the thumb.
The muscular branch supplies the thenar eminence while the palmar digital branch supplies sensation to the palmar aspect of the lateral 3 ?digits and the lateral two lumbricals.
As a note, a patient with true carpal tunnel syndrome ( entrapment of the median nerve within the carpal tunnel ) will not have any sensory loss over the thenar eminence ( bulge of muscles in the palm of hand and at the base of the thumb ).
