Neuron

Noun, pl. neurons 1. An electrically excitable cell that processes and transmits information through electrical and chemical signals. A chemical signal occurs via a synapse, a specialized connection with other cells. Neurons connect to each other to form neural networks. Neurons are the core components of the nervous system, which includes the brain, spinal cord, . . .

The Neuron – Internal Structure

Now that we’ve covered the external structure of the coolest cell in the body–the neuron(!), let’s look at it’s internal structure. Smaller Structures Inside The Neuron Like most cells, the neuron contains: 1. A nucleus - that contains the chromatin and the genetic make-up of the organism. The nucleus is generally located in the soma of the cell. . . .

The Neuron – External Structure and Classification

The Neuron The neuron is, in my opinion, the coolest cell type with the most mind blowing structure you could find in any organism. Period. The neuron’s main function is to transmit electrical signals (information) in one direction (dendrite to axon). The neuron is said to be polarized because information can only travel in a . . .

004 Ion Channels: The Proteins in the Membrane of Neurons

There are 4 important classes of proteins in the membrane of neurons: Passive/Leakage ion channels, Sodium-Potassium pumps, Voltage-gated ion channels, and Ligand-gated ion channels. In order to understand how the neuron functions, we have to understand how those channels work. Watch the following video to learn about these proteins.
