Synapes
It's electric!
Central Nervous System
Peripheral Nervous System
Senses
100
Neuron conducting impulses toward the synapse (send info)
Presynaptic Neuron
100
Neurotransmitters open chemically gated channels, locally graded net potential
Excitatory postsynaptic potential (EPSP)
100
Executive suite, site of conscience mind (all are interneurons, no axons)
Cerebral cortex
100
The awareness of changes in the internal and external environment
Sensation
100
Modified neurons in the neural layer of the retina
Photoreceptors
200
Neuron transmitting electrical signals away from synapse (receives info)
Postsynaptic Neuron
200
Neurotransmitters open chemically gated channels and allow the entrance of ions that cause hyperpolarization
Inhibitory postsynaptic potential (IPSP)
200
Hemispheres are concerned with opposite sides of the body
Contralateral
200
The conscience interpretation of stimuli
Perception
200
The process by which light energy is converted into a graded potential by photoreceptors and bipolar cells
Phototransduction
300
Releases and receives neurotransmitters, most common
Chemical Synapses
300
Presynaptic neuron sends impulses in rapid fire to a postsynaptic neuron
Temporal Summation
300
Specialization of cortical functioning only in one hemisphere (rt or left brain)
Lateralization
300
The energy of stimulus is converted into a graded potential (generator potential)
Transduction
300
SHOW THE PATHWAY OF SOUND
400
Neurons are electrically coupled, joined by gap junctions, communication is very rapid, rare and is primarily in the brain
Electrical synapses
400
Postsynaptic neuron stimulated by multiple terminals simultaneously
Spatial Summation
400
An impermeable barrier that keeps the brain from many blood-borne substances, may maintain a stable environment for the brain
Blood-brain barrier
400
Change in sensitivity in the presence of a constant stimulus
Adaptation
400
Sense of smell (includes pain and temperature receptors (smell hot and cold)
Olfaction
500
DRAW A SYNAPSE
500
Language of the nervous system
Neurotransmitters
500
Contains CSF, 3 layers (Dura mater, arachnoid mater, and pia mater, encloses venous sinuses
Meninges
500
Clusters of neuron cell bodies
Ganglia
500
Sweet, Sour, Salty, Bitter, Umami (Savory/meaty)
The five sensations of taste
