Many of the enzymatic reactions of coagulation leading to thrombin generation are conserved in avian species; however, there are important differences from mammals. Moreover, thrombocytes, the avian equivalent of mammalian platelets, are unique.

WebThe first stage of hemostasis is called the neurogenic mechanism or vessel spasm. This step is characterized by an immediate reflex initiated by nociceptors in the vascular wall.
