The neck differs clearly from both the head and the tail in certain morphological features of the plasmalemma, a sharp demarcation of its upper limit by the posterior ring, and lack of continuity between the segmental columns and the outer dense fibres of the tail (Figs. 57 and 63) (Kaczmarski 1978).

Proteins that have been purified from testes include some of defined function, e.g. enzymes, and some that play an as yet unknown structural role, e.g. plasma membrane components. Many of the proteins that are formed during spermatogenesis represent potential autoantigens,
