Halakhah for Bekhorot 89:46
גזירה שאינה נספרת אטו נספרת
If the additional finger is considered a limb [legally then it should even cause tent uncleanness; and if it is not a limb [legally], then it should not even make a person unclean by contact and by carrying it! - Said R'Huna B'Manoah in the name of R'Aha B'Ika: The Rabbis applied here the rule of a bone which is the size of a barleycorn.<span class="x" onmousemove="('comment',' Which makes a person unclean either by carrying it or coming in contact with it, but does not cause tent uncleanness.');"><sup>25</sup></span>
Peninei Halakhah, Women's Prayer
Women, who do not pray in the synagogue, do not hear the ḥazan, and therefore must practice one would when praying individually. That is, according to Ashkenazic custom, before beginning Shema she says, “Kel Melekh ne’eman” (“God, faithful King”). Even though women have 252 limbs, as the womb has two doors and two hinges (Bekhorot 45a), since all people have 248 limbs, perhaps it is most important to direct the blessings toward them, and the blessing will then continue to the limbs unique to women (Minḥat Elazar 2:28; Ha-elef Lekha Shlomo OḤ 120).
