Biological Perspectives
|
looks at the body and the influences of hormones, genes, brain, and cns on how we think, feel, and act.
|
|
Biological Psychology
|
study of physiological, evolutionary, and developmental mechanisms of behavior and experience
|
|
Sensory Neurons
|
input from sensory organs to the brain and spinal cord
|
|
Motor Neurons
|
output from the brain and spinal cord to the muscle and glands
|
|
Interneurons
|
carry information between to other neurons only found in the brain and spinal cord (relay neurons)
|
|
Most Numerous Neurons
|
Interneurons
|
|
Cell Body (Soma)
|
provides energy for the neuron
|
|
Nucleus
|
contains the cells genetic material
|
|
Dendrites
|
receives information from other neurons
|
|
Axon
|
carries neuron's information to other body areas
|
|
Myelin Sheath
|
provides insulation to the axon
|
|
Neuron to Neuron
|
1. axons branch out and end near dendrites of near cells.
|
|
Axon Terminal (terminal button)
|
are the tips of the axon's branches
|
|
Synapse
|
gap that seperates the axon terminals from dendrites
|
|
Synaptic Vesicle
|
located inside the terminal buttons; they house our neuro transmitter
|
|
Vesicles
|
each houses on kind (type) of neurotransmitter
|
|
Reuptake
|
is when the vesicle reclaims any unused neurotransmitter for later use
|
|
Acetylcholine
|
Important; keeps heart from beating too fast; causes skeletal muscle fibers to contract; involved in learining and memory
|
|
Alzheimer's disease
|
deficiency of acetylcholine
|
|
Dopamine
|
involved in movement; attention and learing
|
|
Schizophrenia and Parkinson's Disease
|
deficiency of dopamine
|
|
Serotonin
|
plays role in appetitie, sleep, regulating mood, aggression, and impulsivity
|
|
GABA
|
the main inhibitory neurotransmitter
|
|
Huntington's Disease
|
deficiency of GABA
|
|
Glutamate
|
the main excitatory neurotransmitter
|
|
Norepinephrine
|
plays role in alertness, sleep, eating, arousal, flight or fight
|
|
Hypothalamus
|
control center of the endocrine system
|
|
CNS
|
consists of brain and spinal cord
|
|
Spinal Cord
|
connects brain and PNS
|
|
PNS
|
carris messages to and from CNS
|
|
PNS Subdivision
|
Somatic Nervous System
Autonomic Nervous System |
|
SNS
|
controls voluntary muscle and transmits sensory info to CNS
|
|
ANS
|
controls involuntary movements
|
|
ANS Subdivisions
|
Sympathetic Nervous System
Parasympathetic Nervous System |
|
Sympathetic NS
|
arouses body for action
|
|
Parasympathetic NS
|
calms body to conserve and maintain energy
|
|
Brain
|
headquaters of your behavior
|
|
Cerebral Cortex
|
makes up 2/3 of brain; is the wrinkles of the brain; highly developed brain; thinking, perceiving, producing, and understanding language
|
|
Left Cerebral Hemisphere
|
language, logic, and calculations
|
|
Right Cerebral Hemisphere
|
visual patterns and spatial relationships
|
|
Corpus Callusum
|
huge bundle of fibers that connect the 2 hemisphere and allows to communicate
|
|
Frontal Lobe
|
front and center; executive (planning, decision making, motor movements, personality regulation, and seeking goals)
|
|
Primary Motor Cortex
|
Boca's Area (plays role in speech production)
|
|
Broca's Aphasia
|
prevents producing speech, but able to understand language
|
|
Parietal Lobe
|
sits at the top of head; process sensory info (touch, pain, locations of limbs, and temperature). somatosensory cortex
|
|
Temporal Lobe
|
sits directly behind ears; primary job to make sense of what you hear
|
|
Auditory Cortex
|
wernicke's area; plays understanding meaningful speech.
|
|
Wernike's Aphasia
|
loss of ability to understand language; word salad
|
|
Occipital Lobe
|
located behind head; proccess visiual info; damage to this area will cause blindness
|
|
EEG
|
records brain wave activity
Beta (mental and physical) Alpha (deep relaxation) Delta (deep sleep) |
|
CT
|
cross sectional images (using radiation)
|
|
MRI
