Answer:
Genetic Engineering is on purpose.
Explanation:
Genetic engineering could range from selective breeding to adding/removing DNA and RNA. Natural reproduction occurs with the sole purpose of creating successful offspring. The offspring could he tainted if the male and female are related leaving it to not have the DNA or RNA necessary to lessen the likelihood of dysfunctional genetics.
<span>Ian Waterman was able to sense pain and temperature because his
spinothalamic pathway was intact, but could not feel touch and limb position because of damage to his
lemniscus pathway. </span>
The lateral spinothalamic tract is a sensory pathway which carries sensory information like pain and temperature to the brain, across the thalamus. Free nerve endings which are located in the peripheral tissues are sensitive to cell damage. Those are primary neurons and they pass the sensory signal. Primary neurons synapse with secondary which are located in the spinal cord (white matter). These secondary neurons will ascend through the brainstem, medulla oblongata, pons and midbrain, until synapsing in the ventroposteriorlateral (VPL) nucleus of the thalamus. From the thalamus, the information is sent to cortex (somatosensory cortex).
Posterior column-medial lemniscus pathway is ascending spinal tract, carrying sensory information to the brain (sensory pathway). It conducts localized sensations of fine touch, vibration and proprioception (position sense) from the skin and extremities (muscles) to the central nervous system (cerebral cortex).
In humans, the medulla region of the brain is mainly responsible for the regulation process of respiration. It is also called the respiratory rhythm centre. The chemosensitive area located near the respiratory centre sends signals across nerve impulses to alter the rate of expiration to eliminate compounds.
