The word thenar originates from the Greek meaning “palm of the hand.” The hypothenar eminence is located on the ulnar portion of the volar hand at the base of the fifth digit (small finger). The thenar eminence is located on the radial portion of the volar hand at the base of the first digit (thumb). The thenar eminence is composed of three muscles that control the movements of the thumb: abductor pollicis brevis (APB), flexor pollicis brevis (FPB), and the opponens pollicis. Medical conditions that can affect the thenar eminence include carpal tunnel syndrome, arthritis, and amyotrophic lateral sclerosis (ALS), among others.
“鱼际”一词源于希腊语，意为“手掌”。小鱼际隆起位于手掌尺侧、小指根部。大鱼际隆起位于手掌桡侧、拇指根部。大鱼际隆起由三块控制拇指运动的肌肉组成：拇短展肌（APB）、拇短屈肌（FPB）和拇对掌肌。可能影响大鱼际隆起的医学病症包括腕管综合征、关节炎和肌萎缩侧索硬化症（ALS）等。
