Spinal cord
Information entering the central nervous system from the external environment is called external stimuli. External stimuli are factors which are detected by the body and communicated to the central nervous system such as temperature and scents.
The nervous system. Which is made up of the peripheral nervous system and the central nervous system (including the brain).
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.
nervous
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.
The rest of the nervous system follows the instructions of the main part that makes the decisions. The main part is the brain, spinal cord, and other interneurons. The rest of the nervous system is called the peripheral nervous system and it mainly receives stimuli with sensory neurons, and sends signals for movement with motor neurons.
Stimuli
Auditory sensory neurons are specialized to detect stimuli from the environment which triggers the neuron to transmit a message to the central nervous system. These stimuli are both voluntary and involuntary.
Information about the environment comes from the senses to the brain via the nervous system.
You can get a nervous breakdown from stress.
