Tissue damage activates nociceptors or pain receptors in the skin. A signal is sent to the peripheral nerve to the spinal cord where neurotransmitters or chemical messengers are released. It activates other nerves to pass signal to the brain. The signals are relayed to the somatosensory cortex for sensation, frontal cortex for thinking and limbic system for emotional response.

Anaphase
Explanation:
Before the mitosis process (where cells multiply creating two new daughter cells from a single cell) chromosomes are replicated and remain attached to their replicates, then they are condensed forming microtubules as they align on the metaphase plate. <em>Now the sister chromatids (replicates) begin to separate to the opposite poles due to the action of the spindle in </em><u><em>anaphase</em></u> (You can observe this in the image I added). Then telophase begins when the nuclear envelope forms back again and chromosomes begin to unroll.
