The Human Nervous System Flashcards
The central nervous system (CNS)
consists of the brain and spinal cord
The peripheral nervous system (PNS)
somatic nervous system and autonomic nervous system (this is then broken down into sympathetic and parasynaptic)
somatic nervous system (SNS)
receives information from the senses and transmits it to the CNS. It also transmits information from the CNS to direct movement of muscles
parasynthetic nervous system
it stimulates functions like digestion. It is involved in “rest & digest” response.
autonomic nervous system (ANS)
Responsible for vital function such as heart beat, breathing, digestion. It transmits information from and to the internal body organs such as the liver and the lungs. It operates, automatically/involuntary.
sympathetic nervous system (SNS)
It inhibits functions like digestion. It is involved with the ‘fight or flight’ response: it happens instantly
the human nervous system
responsible for everything people think, feel, or do
