BIOLOGICAL BASIS OF PSYCHOLOGY
NERVOUS SYSTEM
Central nervous system
Brain
Thinking, feeling and acting
Spinal cord
Connect PNS and brain
Ascending neural fibers
Send up sensory
information
Descending neural fibers
Send back motor-control
information
Peripheral nervous system
Autonomic
Biologically control actions
by body
Somatic
Thinking
in the brain
controls the movement
Neurons
Sensory neurons
Carry information
from sensory neurons to NS
Motor neurons
Carry information
from Central NS to Peripheral NS
Interneurons
Connect
these 2 brain regions
ENDOCRINE SYSTEM
Adrenal glands
Above kidneys
Secreate hormone
Epinephrine
Norepinephrine
Pituitary glands
Most influential
Influence by hypothalamus
Specific
hormone
Growth hormone
Stimulate physical development
Oxytocin
Associate
contractions and birthing
, milk flow during nursing
Thyroid gland
Absorb nutrients from hormones
NEURON TRANMISSION
Dendrites - Axons - Myelin sheath
Action potential
Neurotransmitter
Acetylchloline
Muscle actions
Learning and memory
Dopamine
Movement
Learning
Attention
Emotion
Serotonin
Mood and arosal
Norepinephrine
Alertness and arosal
GABA
Inhibitory transmitter
Glumate
Excitatory neurotransmitter
Neuron
Generate electricity
Ion +
Ion -
Resting potential
Charge ion
Positive / Negative
Refractory
period
A period of time during which an organ or cell is incapable of repeating a particular action
Decision-making devices
Excitatory signals
Inhibitory signals
INFLUENCE OF DRUGS TO NEUROTRANSMISSION
Opiates
Brain indeed produce its own
Endorphins
(Endogenous morphine)
Runner's
high
Relieve pain
Heroine and Morphine
Use too much
can
lead to
stop the brain producing its natural opiates
. Then discomfort when we withdraw it
