The peripheral nervous system is the part of the nervous system excluding the spinal cord and brain. Efferent nerves carry messages from the central nervous system to the rest of the body.
The central nervous system
Central
The main function of the peripheral nervous system is to connect the central nervous system to the limbs and organs. It helps coordinate body movements and receiving external stimuli. It is also the system that controls the "fight or flight" response.
Any internal or external change that brings about a response is called a stimulus. As a key homeostatic regulatory and coordinating system, the nervous system detects, interprets, and responds to changes in external and internal conditions.
Nervous System
The nervous system is triggered to respond to stimuli.
The effectors of the nervous system are muscles and glands. They respond to nervous stimuli.
The system that works closely is the nervous system
The nervous system's ultimate function is to interpret and respond to sensory signals from the environment.The nervous system consists of two main categories:1. Peripheral Nervous System (PNS): receives sensory stimuli, passes stimulus information to CNS in the form of an electrical action potential.2. Central Nervous System (CNS): consists of brain and spinal cord; interprets signals coming from sensory stimuli in the periphery and decides appropriate response to initiate- Afferent neurons transmit sensory signals from the PNS to the CNS- Efferent neurons transmit response signals to targets in the body to respond accordingly to initial sensory stimulus.
The parts of the nervous system that respond to stimuli are called the sensory nervous system. This includes touch, pressure, hot and cold, sound, light, and taste.
Stimuli
By release of chemical neurotransmitters like epinephrine and norepinephrine, increasing response to tough external stimuli.
You can get a nervous breakdown from stress.
