A branch of Psychology that links biology and behavior together
Biological Psychology
Basic building block of nervous system
Neuron
Brushy ends receive and conduct messages
Dendrite
Messages pass through this to other neurons
Axon
Layer of fatty tissue that protects the neurons
Myelin Sheath
Brief impulse, or electrical charge that travels down the axon
Action Potential
Junction between axon tip and dendrite
Synapse
Chemical messengers traveling synaptic gaps between neurons
Neurotransmitters
Enables learning and memory
Acetylcholine
Controls pain and pleasure
Endorphins
Body's communication network
Nervous system
The brain and spinal cord make up this system
Central nervous system
Sensory and motor neurons connecting body
Peripheral nervous system
Neural cables connecting body
Nerves
Carry information from sense receptors to CNS
Sensory neurons
Carry outgoing information from CNS to muscles and glands
Motor neurons
CNS neurons that internally communicate
interneurons
Controls body's skeletal muscles
Somatic nervous system
Controls glands and muscles of internal organs
Autonomic nervous system
Arouses body
Sympathetic nervous system
Calms body
Parasympathetic nervous system
response, like a knee-jerk response
reflex
interconnected neural cells
neural network
Body's chemical communications system
Endocrine system
Chemical messengers created by endocrine
Hormones
Helps to arouse the body in times of stress; you may get a "rush" of this
Adrenal Glands
Regulates growth anf controls other endocrine glands
Pituitary glands
Tissue distruction
Lesion
Measurement of waves of electrical activity in the brain
EEG scan
While scanning brain, it detects where radioactive forms of glucose are going
PET scan
Differentiates brain tissue
MRI scan
Helps detect blood flow in brain
fMRI scan
Central core of brain
Brainstem
Controls heartbeat and breathing
Medulla
Controls arousal
Reticular formation
Brain's "switchborad"
Thalamus
Coordinates movement and balance
Cerebellum
Associated with fear and emotion
Limbic system
Linked to fear and emotion; there are 2 of these in our brain
Amygdala
Directs survival activities
Hypothalamus
Body's control and information-processing center
Cerebral Cortex
Cells that protect neurons
Glial cells
Involved with speaking and muscle movements
Frontal lobes
Receives sensory input for touch and body position
Parietal lobes
Receieve visual information from opposite visual field
occipital lobes
Receives auditory information from opposite ear
Temporal lobes
Controls voluntary movements
Motor cortex
Processes body touch and movement
Sensory cortex
Involved with mental functions like learning and thinking
Association areas
