Neuron

anatomy of neuron

100

the part of the neuron that encompasses the nucleus

The cell body/ soma

200

An organelle that makes proteins in the soma

RER/ Nil bodies

300

This part of the neuron is the main receptive surface of neuron

Dendrites

400

This part of the neuron is the point of initiation of an axon potential

axon hillock

500

this part of the neuron is branching off from the axon, it is not considered to be a separate axon

axon collateral

axon vs dendrites

100

Dendrites carry information to the cell body while axon carry information

They carry information away from the cell body

200

Neurons only have one axon per cell, but a dendrite has how many per cell

There is many dendrites per neuron.

300

This type of structure is only found on dendrites and if you don't use it you lose it!

dendritic spines

400

What body part can an axon travel too

Your toes!

500

What type of surface texture do dendrites have

rough

cytoskeleton

100

What is the smallest part of the cytoskeleton

microfilaments

200

This type of microfilament helps give strength and is the most common

Neurofilaments

300

This part of the cytoskeleton help with structural rigidity, they are hollow and run down the axon, and aid in movement.

Microtubules

400

This type of plasmic transport does not support human life

Slow axoplasmic transport

500

These axon proteins when changed are associated with Alzheimer's Disease

microtubule associated proteins (MAPs)

Neural Plasma Membrane

100

The plasma membrane is consider to be what type of model

Fluid-mosaic model

200

This structure contains hydrophobic non-polar tails with polar phosphate heads.

Phosopholipid bilayer

300

This type of channel allows ions to leak through if they are a specific size, shape, and charge

passive channel

400

This type of channel will only open when the membrane is at a certain voltage and this channel is a key player in action potentials

Voltage gated sodium channel

500

This Active channel is found on dendrites and helps with synaptic potentials

Chemical-gated channels

Neuroglia

100

This cell type is the most abundant cell in the brain.

Neuroglia

200

This cell is responsible for mylenating the CNS

Oligodendrocytes

300

This type of cell is consider to the be immune system soldier of the brain and is derived from hematopoietic stem cells.

Microglial cells

400

This cell can only myelinate a single axon

Schwann cell

500

This cell helps maintain an appropriate chemical environment for neuronal signaling

Astrocyte cell
