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
The somatic nervous system (SNS) is the part of the peripheral nervous system that controls voluntary movement and processes external stimuli through two types of neurons: motor neurons (activating muscles) and sensory neurons (relaying information to the central nervous system).| Simply Psychology
The forebrain, midbrain, and hindbrain are the three main brain divisions. The forebrain handles higher cognitive functions, the midbrain controls motor movement and sensory processing, and the hindbrain manages coordination, balance, and autonomic functions like breathing and heart rate.| Simply Psychology
The brainstem is the stalk-like lower part of the brain that connects the main brain (cerebrum) to the spinal cord. It sits at the base of the skull, just above the spinal cord, and is considered part of the central nervous system (CNS).| 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
Look for inconsistencies in their story, exaggerated details, and avoiding eye contact. Liars tend to touch or cover their mouth more and shift in their seats. They may speak in a higher pitch or clearing their throat often. Pay attention if they repeat your questions before answering and provide extra unsolicited information. These signals suggest dishonesty.| Simply Psychology
Motor neurons are nerve cells that carry messages from the brain and spinal cord to your muscles and glands. They control everything from blinking and walking to breathing and digestion.| Simply Psychology
The sympathetic nervous system is a branch of the autonomic nervous system that prepares the body for "fight or flight" responses during stressful situations. It increases heart rate, dilates pupils, and inhibits digestion, among other functions, to mobilize the body's resources for immediate action.| 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
