Full Definition
النَّسَا
[vulg. عِرْقُ النَّسَا, app. The sciatic vein;] the portion, in the thigh, of the vein (عِرْق) which, in the back, is called the
وَتِين, and which extends to the shank, where it is called the
صَافِن: (IAth, TA, voce أَبْهَرُ:) or the صاَفِن and عرق النسا are two branches of one
عِرْق [or vein]: [in a solid-hoofed animal,] النسا is a vein (عِرْق) proceeding from the hip, or haunch, lying within each thigh, then passing by the hock, so as to reach the hoof: when the breast is fat, each of its thighs becomes cleft by two large portions of flesh, and the
نسا
runs between them, and is apparent. [In the present day it seems to be applied by some to the sciatic nerve: and عِرْقُ النَّسَا, as also النَسَا alone, often signifies sciatica, or hip-gout: see نِقْرِسٌ and also شَنِجٌ.
