2.2 Electrical Communication Study Guide by Hisrich 2.2.a How does communication happen within the body? Electrical Signals Nervous System Chemical Signals Endocrine System The nervous system is made up of neurons. Neurons communicate just like people do‚ but they send messages using action potentials (electricity passing through their axons). Each neuron picks up signals at its dendrites‚ passes the signals down the axon‚ into the axon terminals‚ and into the synapses. The synapse

“How does the brain naturally control pain? And how can we target these systems with treatments?” How does the brain receive pain? The brain receives pain through nociceptive stimuli which activates pain receptors on neurons called nociceptors. Nociceptors can be placed into two categories: A-delta (Aδ) fibres and C-fibres. A-delta fibres are small‚ myelinated‚ neurons that transmit signals fast and mediate sharp pain. C-fibres are smaller unmyelinated neurons that slowly transmit signals. They

The peripheral nervous system is the portion of the nervous system that is outside the brain and spinal cord. Autoimmune means an illness that occurs when the body tissues are attacked by its own immune system. In this case they begin attacking nerve cells which communicate with muscles. They attack the myelin sheaths surrounding the axons of the nerve cells
