- biopsychology
- the nervous system - specialised network of cells + primary internal com system
- CNS - consists of brain and spinal cord + is the origin of all complex decisions and commands
- PNS - sends info from CNS to muscles and glands in the body
- SNS - transmits info from receptor cells to the CNS + receives info from CNS that directs muscles to act
- the endocrine system - instructs glands to release hormones directly into the bloodstream
- fight or flight response - the way we respond to stressful situations
- amygdala [distress signal] --> hypothalamus [distress signal] --> pineal gland [message] --> adrenal gland --> adrenaline is released
- sympathetic state - increased heartrate, increased breath intake, dilated pupils, digestion inhibited, increased saliva production
- parasympathetic state - decreased heartrate, decreased breath intake, constricted pupils, digestion stimulated, saliva production stimulated
- fight or flight response - the way we respond to stressful situations
- neurons
- sensory neuron - carries message from PNS to CNS
- motor neuron - connect CNS to effectors such as muscles
- relay neurons - connect sensory neurons to motor neurons
- synaptic transmission - neighbouring neurons communicate with each other by sending chemical messages across the gap
- neurotransmitters - brain chemicals released from synaptic vesicles that have either an inhibitory or excitatory effect
- excitatory - when a neurotransmitter increases the positive charge of the postsynaptic neuron
- inhibitory - when a neurotransmitter increases the negative charge of the postsynaptic neuron
- neurotransmitters - brain chemicals released from synaptic vesicles that have either an inhibitory or excitatory effect
- the nervous system - specialised network of cells + primary internal com system
