Sympathetic
Somatic nervous system
Voluntary movement
Autonomic nervous system
Not under conscious consciousness (digestion)
2 divisions
Parasympathetic
Sympathetic
What is the parasympathetic nervous system
In control when u are relaxed
Aids in digestion, storing energy, & growth promotion
What is sympathetic nervous system
Activated when your in emergency situations (pain, anger and fear)
Releases norepinephrine which commands body to use stored energy to respond to crisis (increases attention and alertness)
What is the Endocrine system?
Works alongside nervous system to respond to a stressor
system of glands, tissues and cells that control body functions by releasing hormones and chemical messages into blood stream
What is the path of the nervous and endocrine system?
- Brain detects threat
- Neurochem message is sent to the hypothalamus
- Hypothalamus releases corticotropin-releasing factor to the pituitary gland
- Which releases adrenocortotropic hormone (ACTH) into bloodstream
- ATCH reaches adrenal glands which release cortisol and other key hormones into blood stream
When the adrenal gland releases cortisol what happens in the body?
Increased glucose utilization, fat mobilization, and muscle breakdown
What happens simultaneously to the nervous system and brain?
The sympathetic nervous system instructs the adrenal gland to release epinephrine (adrenaline) which triggers bodily changes
What bodily changes occur with the release of epinephrine?
Increased sweating
Decreased salivation
Increased muscular tension and cardiac function
Increased metabolic rate
Decreased digestion rate
Hearing and vision become more acute
Liver releases extra sugar to boost energy
Brain releases endorphins
What is fight or flight in modern life?
