The nervous system controls everything from our thoughts and emotions to our movements and reflexes—but it’s made up of two major parts: the central nervous system (CNS) and the peripheral nervous system (PNS).| Simply Psychology
Think of neurotransmitters as instant messages between nerve cells: fast, direct, and short-lived. Hormones, on the other hand, are more like letters sent through the mail—slower, but able to travel long distances in the body and create lasting effects.| Simply Psychology
Stress is a biological and psychological response experienced upon encountering a threat that we feel we do not have the resources to deal with.| Simply Psychology
The peripheral nervous system (PNS) is critical for connecting the central nervous system (CNS) to the rest of the body. It is essential for bodily functions such as movement, sensation, and autonomic processes.| Simply Psychology
The autonomic nervous system (ANS) is part of the peripheral nervous system (PNS) responsible for regulating involuntary bodily functions, such as heart rate, digestion, respiratory rate, and pupillary response.| Simply Psychology
The parasympathetic nervous system is a subdivision of the autonomic nervous system (ANS), which regulates bodily functions outside of voluntary control, therefore being automatic. It is also called the ‘rest and digest' system as it conserves the body’s natural activity and relaxes the individual once an emergency has passed. It promotes relaxation, energy conservation, and recovery by slowing the heart rate, stimulating digestion, and facilitating other processes when the body is restin...| Simply Psychology
Fear is a basic, emotional response to a perceived threat or danger. It triggers the body's 'fight-or-flight' response, leading to physiological changes like increased heart rate and adrenaline levels. Fear is an essential survival mechanism, helping individuals react to potentially life-threatening situations. It can respond to immediate, tangible threats and more abstract or future concerns. Fear can also be learned through past experiences or observations.| Simply Psychology
The fight or flight response is a physiological reaction that occurs in response to a perceived harmful event, attack, or threat to survival. It prepares your body to either confront or flee from the threat by triggering changes like increased heart rate, quickened breathing, and heightened alertness.| Simply Psychology
