Neuronal Anatomy
This part of the neuron gets its name from a term meaning "body" and is the main part of the neuron
What is the Soma?
This type of gated channel opens because a signaling module binds to the extracellular region of the channel and is also known as an ionotropic receptor.
What is a ligand-gated channel?
This is the most commonly used value for Resting Membrane Potential (RMP).
What is -70mV?
This main neurotransmitter at the neuromuscular junction, parasympathetic nervous system and frontal lobe plays a big part in reward, memory and cognition. The loss of this contributes to the Alzheimer's Disease.
What is acetylcholine?
This part of the brain anterior to the central sulcus is primarily associated with motor function.
What is the frontal lobe?
This is the term used to describe the neurons extensions, or processes.
What are Dendrites?
This type of gated channel opens because of a physical distortion of the cell membrane.
What is a mechanically-gated channel?
This term is used to describe the membrane potential moving towards 0mV and is caused by either mechanically-gated or ligand-gated channels.
What is depolarization?
These neurotransmitters include molecules that are often mimicked by street drugs, examples of which are norepinephrine, dopamine and serotonin.
What are monoamines?
This lobe contains the somatosensory cortex, responsible for sensory input, and the half of Wernicke's area, that manages the understating of speech.
What is the parietal lobe?
This describes the term for the areas of contact where a neuron receives specialized signals from other neurons.
What are Synapses?
This type of channel responds to changes in the electrical properties of the membrane in which it is embedded.
What is a voltage-gated channel?
What is -55mV?
This term is used to describe "cellular math" used by a neuron to figure out the total excitatory and/or inhibitory information it receives during a given time.
This lobe house the visual cortex and receives special visual sensory input.
What is the occipital lobe?
This is the term used to describe a fiber that emerges from the cell body and projects to a target cell.
What is an Axon?
This randomly gated channel opens and closes at an intrinsic rate and contributes to the resting transmembrane voltage of the excitable membrane.
What is a non-gated or leakage channel?
This special region of voltage-gated sodium channels has a collection of amino acids that prevent depolarization's positive feedback loop from spiraling out of control.
What is an inactivation gate?
This term describes when a cell "adds up" all the excitatory postsynaptic potentials and inhibitory postsynaptic potentials and decides if it will fire an action potential or remain at rest.
What is synaptic integration?
This lobe contains the auditory area, involving hearing, and the other half of Wernicke's area that is responsible for understanding speech.
What is the temporal lobe?
This special region is characterized by a tapering of the cell body and is where cytoplasm changes to a solution of limited components called axoplasm.
What is the Axon Hillock or Initial Segment?
This term is used when an ion has many available channels with which to cross a membrane.
What is High Permeability?
During this phase of refractory period, a new action potential can be initiated, if the stimulus is strong enough.
What is the relative refractory period?
These are the four typical signal cessation mechanisms.
What are diffusion, reuptake, protein enzymes and astrocytes?
This lobe of the brain interprets visceral and special sensation as well as processes pain and social signals.
What is the insular lobe?
