superficial response
2.The weakened superficial layers of cartilage develop fissures in response to increased deformation by normal loads.
3.But the recent discovery of detailed similarities in the skeletal structure of the flippers in all three groups undermines the attempt to explain away superficial resemblance as due to convergent evolution—the independent development of similarities between unrelated groups in response to similar environmental pressures.
4.All the results mentioned above lead to the conclusions that OmpL1s is the leptospiral genus-specific superficial protein antigen of L. interrogans and both rOmpL1/1 and rOmpL1/2 can induce humoral response in individuals naturally infected with L. interrogans as well as produce two serum antibodies IgM and IgG with extensive antigenic-cross reaction.
5.A total of 101 retinal ganglion units were recorded from axons and terminal arbours in the superficial layer of the optic tectum of pigeon (Columba livia) and quantitatively analyzed to study the effects of ECMA-lesion on the response properties of retinal ganglion units. In control group, units could be classified into the ON, OFF and ON-OFF transient responses to flashing spots.
