see the abovee post as mentiony by aditi plus

The Abductor brevis, Opponens, and lateral head of the Flexor pollicis brevis are supplied by the sixth and seventh cervical nerves through the median nerve;
the medial head of the Flexor brevis, and the Adductor, by the eighth cervical through the ulnar nerve.

the Flexor pollicis brevis flexes and adducts the proximal phalanx.

The Flexor pollicis longus and Pronator quadratus are supplied by the eighth cervical and first thoracic through the volar interosseous branch of the median.

The volar interosseous nerve (n. interosseus [antibrachii] volaris; anterior interosseous nerve) supplies the deep muscles on the front of the forearm, except the ulnar half of the Flexor digitorum profundus. It accompanies the volar interosseous artery along the front of the interosseous membrane, in the interval between the Flexor pollicis longus and Flexor digitorum profundus, supplying the whole of the former and the radial half of the latter, and ending below in the Pronator quadratus and wrist-joint.

so fpl though supplied by the median nerve it is supplied by its volat intraosseue branch. which ends deep to the wrist joint.it is not affected commonly in carple tunel

and remember abductor plicies bravis is supplies by median nerve and not main abductor that is abductor policies lonus which is supplied by radial.

and adductor polices by ulnar

so answer here is opponens polices only. as fpl is supplied by volar intraosses branch of median nerve
