Cerebral blood flow dynamics under light and heat loads in the lizard phrynocephalus heliscopus

, : Cerebral blood flow dynamics under light and heat loads in the lizard phrynocephalus heliscopus. Fiziologicheskii Zhurnal SSSR Imeni I M Sechenova 75(10): 1405-1408

The role of the parietal and that of the lateral eyes in mediating heat and light impacts on total cerebral blood flow (TCBF) was studied in the lizard. A reduction in the TCBF in response to heat and light effects occurred under control conditions. An extirpation of the parietal eye and screening of the lateral eyes modified the responses of the vascular system increasing the TCBF.

The extrinsic coagulation pathway is activated when tissue factor (TF) is exposed as a consequence of arterial damage. TF binds to factor VII (FVII) or activated FVII (FVIIa), generating a complex that activates both FX and FIX, ultimately leading...
