The following three muscles are considered part of the thenar eminence:

A section of the thenar eminence below the thumb was gone, causing a grooved defect.

It also supplies the muscles of the thenar eminence by a recurrent thenar branch.

It is a thenar muscle, and therefore contributes to the bulk of the palm's thenar eminence.

The most common associated neurological finding is decreased sensation over the thenar eminence due to associated median nerve injury.

Its position is the intersections of the long axes of the four fingers while in a fist, or the base of the thenar eminence.

Characteristic signs include pain, swelling, and ecchymosis around the thenar eminence, and especially over the MCP joint of the thumb.

The thenar eminence is stroked briskly with a thin stick, from proximal (edge of wrist) to distal (base of thumb) using moderate pressure.

(NB: OAF are the thenar eminence)

A good way to remember what muscles are in the thenar eminence is "OAF"; oafs have big thenar eminences.

Also, there's a couple of lacerations on the left wrist and slight contusions on the thenar eminence, indicating that a bracelet may have been forcibly pulled over her hand."

In the thenar eminence it provides motor innervation to opponens pollicis, abductor pollicis brevis and flexor pollicis brevis.

Long-standing CTS leads to permanent nerve damage with constant numbness, atrophy of some of the muscles of the thenar eminence, and weakness of palmar abduction.

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.

Mom was never interested solely in the heart line, head line, and lifelines, but equally in the anatomical snuffbox, the interdigital pads, the heel of the hand, the thenar eminence, and the hypothenar.

In medicine, split hand syndrome is a neurological syndrome in which the hand muscles on the side of the thumb (lateral, thenar eminence) appear wasted, whereas the muscles on the side of the little finger (medial, hypothenar eminence) are spared.

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).

The morphological detail in the cast, particularly impressions of the thenar eminence muscle, also helped convince Krantz, who argued that a hoax "would require someone quite familiar with the anatomy of the human hand to make the connection between a non-opposable thumb and an absence of the thenar eminence."
