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
