Posterior horn Dorsal root ganglia Anterior horn Substantia gelatinosa - correct answers The substantia gelatinosa, which is at the tip of the posterior horn of the spinal cord, is directly involved in pain transmission. Previousquestion Which mechanism of heat loss involves electromagnetic waves? Convection Radiation Conduction Evaporation - correct answers Radiation is heat loss due to magnetic waves from surfaces of higher temperatures to ambient air that is cooler. Which theory of pain best describes phantom limb pain? Pattern theory Gate control theory Neuromatrix theory Specificity theory - correct answers The neuromatrix theory proposes that the brain produces patterns of nerve impulses drawn from various inputs, such as genetic, psychological, and cognitive experiences, and suggests that pain may be felt in the absence of input from the body. This theory would explain the phantom limb pain the woman is experiencing. What is the most critical aspect of correctly diagnosing a seizure disorder and establishing its cause?
