Some analgesic neuropeptides and how they affect the sensation of pain. Introduction: Structures that are specialized for the detection of stimuli such as pain and heat are referred to as sensory receptors. Such receptors can either be real sense organs or simple nerve endings. A sensory receptor converts energy from one form to another. It is involved in the conversion of various forms of stimulus energy, including sound, light, heat, vibration, and touch, into nerve signals. Pain indicates the discomfort that typically leads to evasive action. It is caused by noxious stimulation and injury in tissues. The nociceptors indicate the pain receptors, which respond to the injuries in tissues and situations that lead to the tissue damage. They occur in the protective tissue called meninges and are responsible for headaches. Nociceptors are tonic receptors since the brain must be aware of the pain all the time.

In as much detail as possible, hand draw a schematic diagram of the hypothalamic-pituitary- gonad (HPG) axis in the human male. Be sure to include all the relevant structures and hormones. You must define all abbreviations the first time you use them. Please include (and explain) the feedback loops.

A negligence action was brought by a mother against a hospital on behalf of her minor daughter. It alleged that when the mother was 13 years of age, the hospital negligently transfused her with Rh-positive blood. The mother's Rh-negative blood was incompatible with and sensitized by the Rh-positive blood. The mother discovered her condition 8 years later during a routine blood screening ordered by her healthcare provider in the course of prenatal care. The resulting sensitization of the mother's blood allegedly caused damage to the fetus, resulting in physical defects and premature birth. Did a patient relationship with the transfusing hospital exist?
