"longitudinal division" is a correct and usable phrase in written English.
You could use it when referring to the process of dividing something (perhaps a population) into groups according to a given criterion that runs in parallel to the main body. For example, "The teacher conducted a longitudinal division of the class according to height."
The footbridge arises from the need to connect the locations of Parbayón and Cacicedo, overcoming the longitudinal division of the landscape made by the dual carriageway and providing a striking visual reference point on the site.
Many turbellarians clone themselves by transverse or longitudinal division, and others, especially acoels, reproduce by budding.
Longitudinal division begins when a polyp broadens and then divides its coelenteron, analogous to splitting a log along its length.
The male can be distinguished from Z. rufipes by the large spot of white scales at the beginning of the thoracic slope (which is lacking in Z. rufipes), and by the longitudinal division present on the bulb of the pedipalp (Z. rufipes has a transverse division).
In the toz mutant, the first division of the zygote is normal, but the longitudinal division planes of the apical cell are generally replaced by transverse divisions [ 28].
20% zygotes divided once with either symmetrical division plane resulting in two equally sized cells (Fig. 1F and 1J), or asymmetrically with an enlarged apical cell that could just enlarge but is unable to undergo subsequent longitudinal division (Fig. 1H and 1I).
Although the girth may increase by longitudinal divisions and the widening of the daughter cells, most divisions occur in the transverse plane resulting in the formation of longitudinal files of cells.
Extra precautions are taken, such as adding longitudinal divisions and securing wood atop the cargo.
Subsequently, transverse and longitudinal divisions give rise to an elongated eight-celled proembryo (Fig. 4D).
In the four-celled stage, two longitudinal divisions of the two upper cells produced an octant embryo-proper.
In contrast, some F2 embryos displayed longitudinal divisions, thus altering the radial symmetry of the embryo axis observed in control plants.
