74 Pesachim 7/10-13

(10) The bones, the nerves, and the notar [all of which are left over from the Pesach sacrifice] must be burned on the sixteenth [of Nissan]; If the sixteenth should come out on Shabbat, they must be burned on the seventeenth, since [the burning of these] does not push off [the prohibitions of] Shabbat nor [those] of the festival.

(11) All [parts of the animal] that are eaten of a full grown ox, may be eaten of the tender kid [used for the Pesach sacrifice, including] the tops of the shoulders and the cartilage. One who breaks a bone of a pure Pesach sacrifice, behold he is lashed forty [lashes]; but one who leaves over [a part of] a pure Pesach sacrifice [so that it becomes notar], or one who breaks a bone of an impure Pesach sacrifice, is not lashed the forty lashes.

(12) If part of a limb extends outside [beyond the walls of Jerusalem], one must cut it until [the knife] reaches the bone, and [then] peel off the meat until he reaches the joint, and may [there] cut it off [such that the entire bone be cast away]. And with [regard to other] sacrifices [the bones of which may be broken], the protruding part must be cut off with a chopping knife. If it extends from the‎ door-wing and towards the inside, it is considered as inside; if it extends from the‎ door-wing and towards the outside, it is to be considered as outside [and must be cut off]. The openings in the wall, and its thickness is considered as inside.

(13) If two companies were eating [their Pesach sacrifices] in one house [room], each must turn their faces [in a different direction] while eating it; and the hot water pot should be in the middle [between the two companies]. And when the butler stands to mix the wine [if he has already started to eat from his sacrifice], he must close his mouth and turn his face [towards the company he eats with] until he reaches his company. A bride may, [however,] avert her face [from her company] while eating [the Pesach] sacrifice.
