Intro Ch 1 / 2 Flashcards
pet measures blank flow in brain
oxygen
pet scan stands for
positron emission tomography
fmri measures blank flow in brain
oxygen and blood
three parts of hindbrain
medulla oblongata, pons, cerebellum
three parts of brain
hindbrain, midbrain, forebrain
two parts of forebrain
diencephalon, cerebrum
two parts of diencephalon
thalamus, hypothalamus
four parts of cerebrum
basal ganglia, hippocampus, amygdaloid nuclei, 4 lobes
section of axons that connects the two halves of the brain
corpus callosum
motor cortex is located here
precentral gyrus
somatic sensory cortex is located here
postcentral gyrus
left brain allows one to see blank
right visual field out of BOTH eyes
a spoken word is received in blank, understood by blank, then blank produces speech to repeat the spoken word
auditory cortex, wernickes area, brocas area
reading a word out loud has words read processed in the blank, understood in blank, speech produced in blank, mouth moves because of blank
visual cortex, wernickes, brocas, motor cortex
transition from cell body into axon
axon hillock
four types of neurons
unipolar, bipolar, pseudo-unipolar, multipolar
three types of multipolar neurons
motor spinal cord, pyramidal cell of hippocampus, purkinje cell of cerebellum
three classifications of neurons
afferent, efferent, interneurons
three macroglia nervous system support cells
oligodendrocyte, schwann cell, astrocyte
microglia are just blank support cells
immune system
astrocytes are found in blank matter
white
knee jerk reflex in quad has tension sensed by blank
muscle spindle
exciting one motor pathway and inhibiting opposite motor pathway is an example of blank
feedforward inhibition
an effect that turns off an effect once activated to a certain degree
feedback inhibition
neurotransmitters are blank signals
electrochemical
short term physiological changes can change the synaptic effectiveness permanently
plasticity
neuronal network is plastic and can constantly blank
change
