continuous conduction – gradual propagation of an motion likely together an unmyelinated axon owing to voltage-gated Na+ channels Found along the whole size of the cell membrane.
bronchoconstriction – decrease in the size of the bronchiole as a result of contraction in the muscular wall.
cleavage – sort of mitotic mobile division in which the mobile divides but the total volume stays unchanged; this process serves to generate scaled-down and smaller cells.
