Flexor Pollicis Brevis flex the metacarpophalangeal and carpometacarpal joints leading to the opposition of the thumb and, if continued, produces the medial rotation of the thumb. Due to this function, we are able to manipulate objects and create tools. It plays role in fine movements like precision, pinching, and power griping. [4]

The flexor pollicis brevis is a muscle in the hand that flexes the thumb. It is one of three thenar muscles. [1][2] It has both a superficial part and a deep part. The muscle's superficial head arises from the distal edge of the flexor retinaculum and the tubercle of the trapezium, the most lateral bone in the distal row of carpal bones. [1] .

2023年11月13日 · Flexor pollicis brevis is a short, broad intrinsic muscle of the hand. Together with opponens pollicis and abductor pollicis brevis, it comprises the group of thenar muscles. Flexor pollicis brevis is composed of superficial and deep heads. However, the deep head can vary in size and sometimes even be absent.

2024年2月5日 · Trigger thumb typically results from the thickening of the A1 pulley, impairing the free movement of the FPL tendon. This results in pain, reduced functionality, and a clicking or popping sensation on the attempted extension of the thumb. Both adults and children can experience trigger thumb.

In muscle testing, a normal result is a positive one. During a normal muscle test, the examiner should observe a normal muscle contraction that can move the joint or tendon against full resistance. In muscle testing, an abnormal result is a negative one.

FP（Fabry-perot）激光器 是以FP腔为谐振腔，发出多纵模相干光的半导体发光器件。 FP 激光器主要用于 低速率短距离传输，比如传输距离一般在 20公里以内，速率一般在 1.25G以内，FP的分两种波长， 1310nm/1550nm。 现在市场上也存在一些制造商为了降低成本用FP的器件制作千兆40km的 光纤模块，为了达到相应的传输距离，必定调大发射光功率，长时间工作会提前让产品的器件老化，缩短使用寿命。 根据工程师的建议 1.25G 40km的双纤模块，应用 DFB器件 更为 …
