By physiological aspects I mean those topics of research which are not yet fully understood in terms of biochemistry and biophysics. Several major fields of biology are involved here (e.g. circadian clocks, cell gradient phenomena, hormone action and the control sequences of differentiation, neurosecretory action). Often the gaps in our knowledge include ignorance of details on the ultrastructural level—for example the morphological location of clock mechanisms, the co-ordination mechanism between cells in cell gradient behavior, the sites of action of various hormones, the exposing of sets of genes in correct order, the site of action of neurosecretory chemicals. Arthropod epidermal cells are so versatile that the proper study of the integument includes all of these fields. Because of the nature of its content therefore, this chapter is necessarily less integrated than the previous one.
