Unit 2 Flashcards
Cerebellum (Very Bad lice)
Voluntary Movement
Balance
Learning and memories
Thalamus
Relays messages
Pituitary
Master gland of Endocrine System
Spinal cord
Pathway for neural fibers
Controls simple reflexes
Amygdala
Limbic system
Liked to emotion
Aggression and fear
Hippocampus
Limbic system
Linked to memory
Hypothalamus
Limbic system
Maintenance functions
Governs endocrine system
Fighting, Fleeing, Flirting, FeedIng
Limbic system HAH!
Hypothalamus
Amygdala
Hippocampus
Reticular formation
Brain stem
Arousal
Pons
Brain stem
Coordinates movement
Medulla
Brain stem
Heartbeat
Breathing
Brain stem Mustard ranch pickles
Medulla
Reticular formation
Pons
Cerebral cortex
Control and information processing center
Soma
Keeps cell alive
Dendrite
Receive messages from cells
Axon
Fires action potential, passes messages
Myelin
Covering on axon,. Weak myelin-> MS
After passing through axon
Neurons travel through axon branches to terminal buds
Neurons..
Transmit action potential and release neurotransmitters.
Synaptic gap
Gap between neurons where information is transmitted
Antagonist
Blocks the synaptic receptor
Agonist
Mimics the neurotransmitter by binding to synaptic gap
Increases neurotransmitter effect
Gilal Cells
Neurotransmitters nanny
Vesicle
Stores neurotransmitters
Action potential—> In pump:
Sodium on outside and Potassium inside- goes through pump- Sodium on inside and Potassium outside
A stronger mylein sheeth
Makes neurons travel faster and fire faster
The resting potential is
-70mv
Excitatory makes…
The neuron fire
Gluteamate GO!
Inhibitory
Stops neurons from firing
GABA- yo Gaba Gaba at bedtime
Phrenology
Measuring bumps on skull to study traits
Depolarize
Immediately after neuron fires
Repolarize
Neuron recharging to fire again
Refractory period
Time between neurons firing
Reuptake
A neuron transmitter returning to vesicle
SSRI
Selective serotonin Reuptake inhibitors
Keeps senetonin in synapsis to continue binding and making you happy
CNS
Brain/Spinal Cord
Nervous systems decision maker
Interneurons- neurons that think
Peripheral nervous system
All other neves besides CNS.
Sensory neurons
Carries messages from senses to brain
PNS separates into
Somatic And Autonomic
Somatic controls skeletal muscles
Autonomic
Glands/internal organs muscles
Autonomic-Inhibitory
Sympathetic-Excitatory (fight or flight
Autonomic separates into
Parasympathetic and sympathetic
Sympathetic-Fight or flight
Para sympathetic- relaxation/inhibitory
AcH
ACTION
Muscle action, memory, learning
Endocrine passes messages using
Hormones
Adrenal Gland/Pituitary Gland
Adrenaline/Epinephrine
/Master Gland receives information from hypothamlus
Motor/Somosensory cortex
Motor-voluntary movement
Somosensory-Makes you aware of movement
Brocas/Wernickes
Producing sound/interpreting it
Left Hemisphere
Speech and abstract thinking
Right Hemishpere
Problem solving, memory, reasoning, emotion motion
CONTROLLS LEFT SIDE
TRANSMITS MESSAGES THOUGH CORPUS CALLOSUM
Left Hemisphere
Speech, interpreting speech, comprehension, creativity abstract thinking
CONTROLLS RIGHT SIDE
TRANSMITS MESSAGES THOUGH CORPUS CALLOSUM
