MUSCLE PHYSIOLOGY

Detailed explanation-1: -Most notably, the insula and anterior cingulate cortex are consistently activated when nociceptors are stimulated by noxious stimuli, and activation in these brain regions is associated with the subjective experience of pain.

Detailed explanation-2: -Parietal lobe. The middle part of the brain, the parietal lobe helps a person identify objects and understand spatial relationships (where one’s body is compared with objects around the person). The parietal lobe is also involved in interpreting pain and touch in the body.

Detailed explanation-3: -But the truth is, pain is constructed entirely in the brain. This doesn’t mean your pain is any less real – it’s just that your brain literally creates what your body feels, and in cases of chronic pain, your brain helps perpetuate it.

Detailed explanation-4: -Pain-sensing neurons are called nociceptors. They respond to extreme temperature, pressure, or chemicals from damaged cells. Nociceptors are found throughout our skin, muscles, bones, and internal organs. Once the ascending message reaches the brain, it’s translated and we feel pain.
