Loss of large myelinated nerve fibres of the recurrent laryngeal nerve in patients
with multiple system atrophy and vocal cord palsy.
多系統萎縮和聲帶麻痺患者喉返神經損傷有大髓鞘神經纖維損失。
The small myelinated nerve fibres (diameter < 7 microm) were decreased in number
in both multiple system atrophy groups,
在多系統萎縮組中,有小的髓鞘神經纖維(直徑<7 microm)數量減少
whereas the large myelinated nerve fibres (diameter < 8 microm) were decreased
only in those with vocal cord palsy, and preserved in those without the symptom.
大的髓鞘神經纖維(直徑<8 microm)僅在聲帶麻痺患者中減少
In multiple system atrophy, the small myelinated fibres innervating the vocal cord
are affected first, without obvious clinical signs.
在多系統萎縮中,支配聲帶的小髓鞘纖維首先受到影響,沒有明顯的臨床症狀。
The patient develops vocal cord palsy only after the loss of the large myelinated fibres,which mostly comprise the alpha motor axons that innervate the intrinsic laryngeal muscles.
患者僅在失去大的髓鞘纖維後才會出現聲帶麻痺,這種纖維主要包括支配內在喉部肌肉的α運動軸突。
Laryngeal Neuropathy in Adult Goats With Copper Deficiency.
銅缺乏的喉部神經病變
We concluded that the stridor was caused by axonal degeneration of
the recurrent laryngeal nerves due to the severe copper deficiency.
我們得出結論,喘鳴是由於嚴重的銅缺乏引起的喉返神經的軸突變性引起的。
