anatomy of neuron
the part of the neuron that encompasses the nucleus
The cell body/ soma
Dendrites carry information to the cell body while axon carry information
They carry information away from the cell body
What is the smallest part of the cytoskeleton
microfilaments
The plasma membrane is consider to be what type of model
Fluid-mosaic model
This cell type is the most abundant cell in the brain.
Neuroglia
An organelle that makes proteins in the soma
RER/ Nil bodies
Neurons only have one axon per cell, but a dendrite has how many per cell
There is many dendrites per neuron.
This type of microfilament helps give strength and is the most common
Neurofilaments
This structure contains hydrophobic non-polar tails with polar phosphate heads.
Phosopholipid bilayer
This cell is responsible for mylenating the CNS
Oligodendrocytes
This part of the neuron is the main receptive surface of neuron
Dendrites
This type of structure is only found on dendrites and if you don't use it you lose it!
dendritic spines
This part of the cytoskeleton help with structural rigidity, they are hollow and run down the axon, and aid in movement.
Microtubules
This type of channel allows ions to leak through if they are a specific size, shape, and charge
passive channel
This type of cell is consider to the be immune system soldier of the brain and is derived from hematopoietic stem cells.
Microglial cells
This part of the neuron is the point of initiation of an axon potential
axon hillock
What body part can an axon travel too
This type of plasmic transport does not support human life
Slow axoplasmic transport
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
This cell can only myelinate a single axon
Schwann cell
this part of the neuron is branching off from the axon, it is not considered to be a separate axon
axon collateral
What type of surface texture do dendrites have
rough
These axon proteins when changed are associated with Alzheimer's Disease
microtubule associated proteins (MAPs)
This Active channel is found on dendrites and helps with synaptic potentials
Chemical-gated channels
This cell helps maintain an appropriate chemical environment for neuronal signaling
Astrocyte cell
