biopsychology: the nervous system and the endocrine system
the nervous system
- it is a specialised network of cells (primary internal communication system
- 2 main functions
- collect, process and respond to info
- co-ordinate the workings of different organs
- 2 sub systems
- central nervous system
- brain and spinal chord
- brain
- centre of all conscious awareness
- 2 hemispheres
- distinguishes us from animals
- 2 hemispheres
- centre of all conscious awareness
- spinal chord
- reflex actions
- messages to and from the brain and the PNS
- reflex actions
- brain
- brain and spinal chord
- peripheral nervous system
- transmits messages through neurons to and from the CNS
- 2 sub groups
- autonomic NS
- governs automatic functions
- breathing
- digestion
- governs automatic functions
- somatic NS
- muscle movement
- receives info from senses
- muscle movement
- autonomic NS
- 2 sub groups
- transmits messages through neurons to and from the CNS
- central nervous system
- 2 main functions
- it is a specialised network of cells (primary internal communication system
the endocrine system
- works alongside NS
- slower than the NS but widespread powerful effects
- glands and hormones
- glands produce hormones
- hormones secreted in the bloodstream
- affect every cell in the body that has a receptor for that hormone
- hormones secreted in the bloodstream
- most hormones effect cells in most organs
- leading to different and powerful responses
- main gland - pituitary gland in brain
- master gland
- controls the release of hormones form all the endocrine glands in the body
- master gland
- main gland - pituitary gland in brain
- leading to different and powerful responses
- glands produce hormones
- glands and hormones
- slower than the NS but widespread powerful effects
- endocrine and ANS work together: fight or flight
- when a stressor happens - hypothalamus in the brain triggers activity in the sympathetic part of the ANS
- changes from resting (parasympathetic) to aroused sympathetic
- stress hormone releases adrenaline
- pupils dilate, heart rate increases, lungs dilate, digestion stops, liver makes adrenaline
- happens instantly
- parasympathetic returns it to its resting place
- happens instantly
- pupils dilate, heart rate increases, lungs dilate, digestion stops, liver makes adrenaline
- stress hormone releases adrenaline
- changes from resting (parasympathetic) to aroused sympathetic
- when a stressor happens - hypothalamus in the brain triggers activity in the sympathetic part of the ANS
- works alongside NS
