lac·ri·mal gland

[TA]
the gland that secretes tears into the conjunctival sac; it consists of 6-12 separate compound tubuloalveolar serous glands, located in the upper lateral part of the orbit. It is partially divided into a smaller palpebral part (pars palpebralis) and a larger orbital part (pars orbitalis) by the aponeurosis of the levator palpebrae muscle.
