|
What is Dualism?
|
The mind(brain) and body are separate.
|
|
|
What is monism?
|
mind and body (brain) are same; reality consists of unified whole
mind is the working of brain and nervous system (neurons firing) |
|
|
What are some physiological changes the Sympathetic nervous system causes?
|
Dilated pupils, accelerated heartbeat, inhibited digestion, constricted blood vessels in the skin, secretion of sweat glands.
|
|
|
What are some physiological changes caused by the Parasympathetic nervous system?
|
Constricts pupils, slows heartbeat, stimulates digestion, dilates blood vessels in skin, stimulates salivation.
|
|
|
What is the difference between afferent and efferent?
|
Afferent : toward the CNS (from sensory to brain)
Efferent : from the CNS (from brain to neurons to stimulate a response) |
|
|
Coup and Contre Coup.
|
Coup: site of the injury
Contre Coup: worse damage on the opposite side of coup b/c it bounced back. |
|
|
Grey matter in spinal cord.
|
Cell bodies
|
|
|
White matter in spinal cord.
|
Axons
|
|
|
Spinal tracts
|
Bundle of axons IN the CNS
|
|
|
What is the role of convolutions (folds) in the brain?
|
Allows more tissue in a limited space.
|
|
|
Frontal lobe
|
motor function
prefrontal - higher "executive function" |
|
|
Parietal lobe
|
somatosensory function
EX:touch, hot, cold, vibrations |
|
|
Temporal lobe
|
Auditory and emotion
|
|
|
Occipital lobe
|
Vision
|
|
|
Synapse
|
Tiny gap which separates neurons from each other over which they communicate.
|
|
|
What are the 3 states in which a neuron can exist?
|
Resting state, active state, and refractory state.
|
|
|
Depolarization
|
change from negative inside neuron to more positive.
|
|
|
Hyperpolarization
|
change from positive to more negative
|
|
|
What causes changes in electrical potential?
|
Ions flowing across the membrane is what causes the changes in the potential between the inside and outside of the axon.
|
|
|
Anion
|
negative charge
|
|
|
Cation
|
positive charge
|
|
|
What causes the resting state, active state, and refractory period?
|
Message is carried down the axon by changes IN THE MEMBRANE OF THE AXON that causes changes b/t various ions inside and outside the axon of the neuron.
|
|
|
Concentration Gradient
|
Ions diffuse from higher concentration to lower concentration.
|
|
|
Electrical Gradient
|
Opposite charges attract so ions are attracted to an environment that has a charge that is opposite of the charge they carry.
|
|
|
What drives the action potential?
|
Opening of Na+ channels and influx of Na+ ions.
|
