Biopsychology
The Nervous System
Controlled by sympathetic nervous system
fight/flight response Sympathetic and parasympathetic are constantly shifting to maintain
equilibrium
The Endocrine System
In charge of slow bodily processes
⤷ Hormones = chemical substances that
circulate in the blood and affect target
organs
Pituitary = controls release of all hormones
Thyroid = releases thyroxine (heart, metabolic
rate, growth rate)
Hypothalamus = controls homeostasis
(influences ANS + hormone)
, Neurons
Cells that conduct nerve impulses/ action potential (electrochemical signals controlling behaviour
and thought)
Dendrite = carries impulses from neighbouring neuron
into cell body
Axon = carries impulse away from cell body
Myelin sheath + Nodes of Ranvier = speed up
transmission
Terminal Buttons = communicates with next neuron
across synapse
