Human Anatomy & Physiology Reflex Physiology lab Objectives: To understand what reflexes are, the processes involved, and purpose of reflexes. Introduction: A reflex is an involuntary neural response to a specific sensory stimulus that threatens the survival or homeostatic state of an organism.n humans and other vertebrates, protective reflexes have been maintained and expanded in number.
