The Sexual Assault Nurse Examiner (SANE) is an RN with specialized education and clinical preparation in the forensic examination of sexual assault survivors. The examination involves a comprehensive medical-forensic approach that simultaneously addresses the survivor's medical needs and collects evidence for potential criminal prosecution. The tonic immobility response during assault—a parasympathetic-mediated state of involuntary paralysis occurring in 12-50% of victims—explains why many victims do not fight back or scream, countering common misconceptions about 'expected' victim behavior. This is a neurobiological survival response, not consent. The fight-flight-freeze response is mediated by the amygdala bypassing conscious decision-making through the thalamo-amygdalar pathway. Trauma memories are stored as fragmented sensory fragments rather than coherent narratives because the hippocampus (responsible for contextual memory consolidation) is suppressed during extreme stress while the amygdala encodes emotional and sensory associations. This explains why victim accounts may seem inconsistent or fragmented—this is a NORMAL neurobiological response to trauma, not evidence of fabrication.
