The most interesting aspect of working with firearm evidence is finding out which type of firearm was used and inspecting the bullet and matching it to the archives of guns and bullets. However, the challenging part is tracing which person used the firearm and evidence and is the suspect of a crime. Also, tracing the movement of the bullet used from where it was shot and where it landed. It's very hard to know which person used the firearm as the end user.
Answer: Third-order neurons
Explanation:
Third-order neurons in the thalamus, brainstem, and midbrain project to the central nervous system, which allows pain perception and interpretation.
Also, the limbic and reticular tracts are activated by third-order neurons, resulting in arousal and emotional responses to pain.
When stimulated, nociceptors (first-order neurons) in the skin, muscles, joints, arteries, and viscera transmit pain impulses to the spinal cord.
Second-order neurons in the dorsal horn of the spinal cord transmit the pain impulse to higher brain areas via spinal pathways.
The thalamus is the primary relay station for pain impulses.
