Microtomy
Definition:

(17) This approach offers several advantages over existing techniques: 1) uniform section thickness is more easily obtained than with paraffin or cryostat microtomy, thereby allowing improved resolution and more reliable identification of mesenchymal cells with small nuclei such as skeletal muscle myocytes or fibroblasts, 2) the preparations are stable over long periods and can be repeatedly viewed or photographed, and 3) calcified tissues can be examined without prior decalcification.

(19) This study has been made possible by two technological advances, firstly the development of cryostat microtomy for cutting unfixed, undemineralised bone, and secondly the use of scanning and integrating microdensitometry for quantifying the activity in each periosteal cell.
Slice
Definition:

(v. t.) A plate of iron with a handle, forming a kind of chisel, or a spadelike implement, variously proportioned, and used for various purposes, as for stripping the planking from a vessel's side, for cutting blubber from a whale, or for stirring a fire of coals; a slice bar; a peel; a fire shovel.
(v. t.) One of the wedges by which the cradle and the ship are lifted clear of the building blocks to prepare for launching.
(v. t.) A removable sliding bottom to galley.
(v. t.) To cut into thin pieces, or to cut off a thin, broad piece from.
(v. t.) To cut into parts; to divide.
(v. t.) To clear by means of a slice bar, as a fire or the grate bars of a furnace.
Example Sentences:
(1) Microionophoretically applied excitatory amino acids induced firing of extracellularly recorded single units in a tissue slice preparation of the mouse cochlear nucleus, and the similarly applied antagonist 2-amino-5-phosphonovalerate (2APV) was demonstrated to be a selective N-methyl-D-aspartate (NMDA) receptor antagonist.
