only when your organs rise up and your brain is put under stress.
Breathing, blinking, and regulating body temperature are examples of actions that occur because of automatic processing in the body. These functions are essential for our survival and are controlled by the autonomic nervous system without conscious effort.
The processor (aka CPU - Central Processing Unit)

Neural processing can involve both serial processing where information travels in a linear pathway to a specific destination, as well as parallel processing where information travels along multiple pathways to integrate in different regions of the central nervous system. These processes can occur simultaneously and play a role in the complex functioning of the brain.

Synapses are important for the functioning of the nervous system because they allow for communication between neurons. This communication is essential for transmitting signals and information throughout the brain and body, enabling processes such as thinking, feeling, and movement to occur.

The nervous sysytem is the control unit of the body.It is responsible for regulating and coordinating the activities of all the other sysytem of the body.Through the nervous systemthe body is able to adjust to changes that occur within itself and in its surroundings. It is divided into 2 principal systems: -The Central Nervous System -Peripheral Nervous System

Usually when we talk about reflexes -we are referring to two things: primary sensory processing (peripheral nervous system) followed by a motor response (central nervous system). These types of reflexes do not require higher-order cognitive function to occur - but the brain is made aware of what is going on, presumably so that we learn to avoid the harmful stimulus in the future. For example, the accidental placement of a hand on a hot surface would usually result in an immediate withdrawal reflex. What's happening here is that pain receptors in the skin - in this case 'nociceptors' activated by thermal stimuli - send impulses to neurons in the spinal cord (the spinal cord is part of the central nervous system) that share circuits with neurons that control muscle contractions. These in turn fire, resulting in an immediate flexion (movement toward the body) of the affected limb.
The sympathetic nervous system originates in the spinal cord and its main function is to activate the physiological changes that occur during the fight-or-flight response.
