Neurons
Action Potentials
Neuroglia
Brain
Meninges and Spinal Cord
100
These branch-like structures of neurons take in information from other neurons.
Dendrites
100
This is the name given to the charge -70mV where a neuron spends the majority of its time waiting for stimuli.
Resting Potential
100
This type of cell is known to help regulate the nutrition of neurons by facilitating transport from blood vessels to neurons
astrocytes
100
This region of the brain is responsible for coordinating movement and balance.
Cerebellum
100
this type of nerve tract carries sensory information to the brain
ascending tract
200
Motor neurons fire impulses along their length until they reach this type of organ that responds to the stimuli.
Effector
200
This type of cell membrane gate responds to changes in electrical potential to open and allow select ions through.
Voltage-gated ion channel
200
What is the scientific sounding name for the process carried out by microglial cells
phagocytosis
200
This name is given to the piece of tissue to which the pituitary gland attaches
Infundibulum
200
This layer of the meninges is formed largely of fibrous connective tissue that protects the spinal cord
Dura Mater
300
This type of neuron classified by shape.
Bipolar
300
This is the voltage at which sodium voltage gates open
-55mV
300
Schwann Cells are responsible for producing myelin in what area of the body
Peripheral Nervous System
300
This region of the brain is responsible for both auditory and visual memory
Temporal Lobe
300
This region of the spinal cord is found between two layers of meninges and is filled with CSF
Subarachnoid space
400
At the synapse this type of molecule ends up passing impulses from one neuron to the next.
neurotransmitter
400
Action potentials are kicked off by a series of events at the synapse. The first event occurring at the post-synaptic neuron involves the movement of what molecule?
sodium ion
400
This molecule produced by several different neuroglial cells is responsible for speeding up signal transduction
myelin
400
The primary motor areas are found in the frontal lobe just anterior to this brain landmark
Central Sulcus
400
This structure contains many of the blood vessels that nourish the brain and spinal cord
pia mater
500
Multiple Sclerosis is a type of degenerative disease that destroys the myelin wrapped around neurons. What is one direct outcome of this.
slower signal transduction
500
Describe why the neuron has an all-or-none response.
sodium channels open at -55mV no lower
500
This structure can be used to quickly differentiate between oligodendrocytes and Schwann cells
Neurilemma
500
This piece of tissue divides the brain into hemispheres
corpus callosum
500
This region marks the point where spinal nerves branch off and lead to the arms
Cervical Enlargement
