Psych Unit 1 test
cell body - the cells life support
dendrites - receive messages from other cells
axon - passes messages away from the body to other neurons
Myelin Sheath - covers the axon of some neurons and helps speed neural impulses
Terminal Knobs - form junctions with other cells
neuron - basic building block of the nervous system
Action Potential - A neural impulse; a brief electrical charge that travels down an axon
Synapse - junction between the axon tip of the sending neuron and the dendrite or cell body of the receiving neuron
Acetylcholine - what it does (Enables muscle action, learning and memory) examples (Under-supply marks Alzheimer’s disease)
Dopamine - what it does (Influences movement, learning, attention and emotion) examples (often linked to Schizophrenia, Brain produces tremors, Parkinson’s)
Serotonin - what it does (affects mood, hunger, sleep and arousal) examples (under-supply causes depression)
Norepinephrine - what it does (controls alertness and arousal) examples (under-supply can depress mood)
GABA - what it does (major inhibitory neurotransmitter) examples (undersupply linked to seizures, tremors and insomnia)
Glutamate - what it does (major excitatory neurotransmitter; involved in memory) examples (over-supply can produces migraines or seizures)
Endorphins - what it does (linked to pain, control and to pleasure)
Nervous System - the body’s speedy, electrochemical communication system
Autonomic Nervous System - controls self-regulated actions of internal organs and glands
Somatic Nervous System - controls voluntary movements of skeletal muscles
Sympathetic - arousing (fast)(fight or flight system)
Parasympathetic - calming (slow)(long-term survival)
Hypothalamus - neural structure lying below (hypo) the thalamus; directs several maintenance activities (eating, drinking, body temperature and it is linked to emotion)
Amygdala - two almond-shaped neural clusters that are components of the limbic system and are linked to emotion (Linked with fear and aggression)
Pituitary gland - the major endocrine gland. A pea-sized body attached to the base of the brain, the pituitary is important in controlling growth and development and the functioning of the other endocrine glands.
Hippocampus - the center of emotion, memory, and the autonomic nervous system.
Frontal lobe - Prefrontal cortex, motor cortex, Brocas cortex
Parietal lobe - sensory cortex, wernicke’s cortex
Occipital lobe - visual cortex
Temporal lobe- auditory cortex
Cerebellum - helps coordinate voluntary movement and balance
Medulla - the base of the brainstem, controls heartbeat and breathing
Reticular Formation - a nerve network in the brainstem that plays an important role in controlling arousal
Pons - handles unconscious processes and jobs, such as your sleep-wake cycle and breathing
Corpus Callosum - large band of neural fibers, connects the two brain hemispheres, carries messages between the hemispheres
Thalamus - directs messages to the sensory receiving areas in the cortex and transmits replies to the cerebellum and medulla
Sensory Cortex - responsible for receiving and processing sensory information from across the body, such as touch, temperature, and pain.
Motor cortex - generates signals to direct the movement of the body.
Prefrontal cortex - Digests and processes sensations
Broca’s Area - allows you to speak
Wernicke’s Area- processes language
Brain Plasticity - the brain’s capacity for modification, as evident in brain reorganization following damage (especially in children) and in experiments on the effects of experience on brain development
