They receive information from other nerve cells and send it toward the soma or cell body Cell Body (Soma) Contains nucleus STRUCTURE OF NEURONS Axon the extension of a neuron‚ (long fiber) ending in branching terminal fibers‚ through which messages are sent to other neurons or to muscles or glands (senders).

Neuro notes for test 2! Cell membranes are composed of a lipid bilayer. It has different receptors that allow different ions to pass‚ depending on the conditions in the cell. Leak channels- always open allow ions to flow back and fourth across the cell membrane Na cl ‚K and Ca ions and they just flow back and fourth without any gate keeper or obstruction‚ When the neuron is at rest its cytoplasm is Negatively charged. That means that it is not going under depolarization‚ we use the term resting

On alternate Thursdays‚ it is mandatory that Bernard Marx attend Solitary Service. During this ritual‚ soma is passed around and stimulation is provided until a group of twelve reaches‚ in essence‚ an orgy of faith. This sexual addition to religion is meant to satisfy the body as well as the spirit‚ and keep the sense of community alive. After Solitary Service

In the New World Society‚ a young woman like Lenina should be constantly switching partners. Sex‚ much like the society’s feel-good drug soma‚ is a very instant form of gratification. Building a long term relationship can be emotionally taxing‚ something that society in Brave New World opposes.

cells are the basic functioning component in the nervous system. Every part of the system is comprised of neurons that collect and distribute information to make the body function. All neurons consist of four main components; a soma‚ dendrites‚ an axon and its terminals. The soma is a cell

Dendrite – Are located on neurons and they look like tree shape stems‚ they are what sends the signals out from the neuron and they also receive signals along with sending electrical stimulations to the soma. Synaptic Gap – This is a small gap between the cell membrane and the synapse it separates the neurons and allows the synapse to pass information. Axon – It’s a long slender part of the nerve cell‚ that helps transmit the neural signal. Neurotransmitter

They are the major neuron type in the CNS and include interneurons and motor neurons. • Bipolar neurons: Sensory neurons that have two processes coming off the soma‚ one dendrite and one axon • Pseudo unipolar neurons: Sensory neurons that have one process that splits into two branches‚ forming the axon and dendrite • Unipolar brush cells: Are excitatory glutamatergic interneurons that have a single short dendrite
