Sequence the events of a spinal reflex

Spinal reflex refers to a reflex, which is directed by a nerve pathway with a sensory afferent to the spinal cord, linkages within the cord, and an efferent to muscle from the cord. The spinal reflexes take place in the absence of the influence of the brain.  

The following is the correct sequence of events of a spinal reflex:  

1. Something stimulates a sense, like heat, pain, or smell.  

2. The sensory receptors produce nerve signals, which travel along the sensory fibers via the dorsal-root ganglia towards the spinal cord.  

3. The posterior neurons conduct signals on to interneurons, some of which synapse with the motor neurons.  

4. The nerve signals travel to an effector-like a muscle that brings about a response.  

a few examples of ethical concerns involving genetically engineering of humans include

-privacy of genetically tested people

- potential side effects

-long term effects
