Morphological events

Thrombin and other agents cause platelet aggregation, which involves a variety of biochemical and morphologic events. Stimulation of phosphofipase C and the polyphosphoinositide pathway is a key event in platelet activation, but other processes are also involved. 

Is easily observed as a gross morphological event In which the "old" cuticle remains enveloping the Insect In the pharate condition. The abnormal pharate condition prevents feeding and locomotion, and eventually results In the death of the affected Insect. The Inhibited ecdysls of a Bombyx morl (silkworm) larva Is shown In Figure 2. The larva underwent normal apolysls, but failed to complete ecdysls and could not remove Its head capsule or trunk exuvla and eventually died.

Since chromatin condensation is an early morphological event in apoptosis, early attention was focused on the biochemical changes that bring this about. Chromatin condensation is accompanied by fragmentation of the chromatin into an easily diag-...
