The condition is also known as apical ballooning syndrome ABS and stress cardiomyopathy.
Between late stage 16 and mid-stage 17 the apical plasma membrane of epidermal cells forms regular corrugations called apical undulae (au), at the tip of which chitin synthesis takes place, while secretion occurs at the valley between the corrugations (D).
Plants have a mechanism called apical dominance, by which axillary buds are prevented from growing at the same time as the terminal bud-the tip of the plant stem.
Plowe and his colleagues tested a vaccine that targets a molecule on the malaria parasite known as apical membrane antigen 1 (AMA1).

The epithelia secrete them constitutively into the thin layer of fluid that lies above the apical surface of the epithelium but below the viscous mucous layer.
The new species is highly adapted to hypogean life with very obvious troglobiomorphic features: unpigmented cuticle, an extraordinary lengthening of thorax and appendixes, multiplication of antennomeres and supernumerary placoid sensilla, not just in the apical antennomere but also in the preceding antennomeres.
