What is Neuroscience?
The neuron at rest with a membrane potential of -70mv.
What is resting membrane potential?
This type of transport moves things along the concentration gradient.
What is passive transport?
What is diffusion?
This part of the neuron receives incoming messages.
What are dendrites?
What is a sulcus?
A chemical messenger that can travel across the synapse.
What is a neurotransmitter?
A difference of concentrations between two regions. For example, inside and outside the cell.
What is a concentration gradient?
-80mv, when too much potassium has left the cell
What is hyperpolarization?
The type of transport that allows molecules to travel against the concentration gradient.
What is active transport?
The zone of communication between to neurons.
What is the synapse?
controls vital involuntary functions like breathing, heart rate, and blood pressure, along with reflexes such as swallowing, coughing, and sneezing
What is the medulla oblongata?
This neurotransmitters is commonly known as the "feel good" neurotransmitter as it is integral to the reward pathway.
What is dopamine?
This channel allows for the movement of Na+ ions along the concentration gradient when the channel senses a certain voltage.
What is a voltage gated Na+ channel?
A flow of sodium ions moving into the cell causing an increase in positivity inside the cell.
What is depolarization?
The sodium potassium pump allows this amount of sodium ions out of the cell.
What is 3?
This part of the neuron houses vesicles that contain neurotransmitters.
What is the axon terminal?
Coordinates both the autonomic nervous system and the activity of the pituitary, controlling body temperature, thirst, hunger, and other homeostatic systems, and involved in sleep and emotional activity.
What is the hypothalamus?
This type of clearance removes neurotransmitter by taking it back into the cell that released it.
What is reuptake?
This channel allows for the passive transport of Na+ ions along the concentration gradient when a ligand binds to the channel.
What is a ligand-gated Na+ channel?
A flow of potassium ions to the outside of the cell causing a decrease in positivity on the inside of the cell.
What is repolarization?
A type of passive transport used to move ions and polar molecules with the assistance of channels.
What is facilitated diffusion?
This type of brain cell does not transmit messages but instead supports the nervous system.
What are glial cells?
a fine, delicate membrane, the middle one of the three membranes or meninges that surround the brain and spinal cord.
What is the arachnoid mater?
This neurotransmitter is responsible for muscle movement.
What is acetylcholine?
Who is Mr. Velasco's best friend at SHS?
Who is Mrs. Kling?
During this time a neuron cannot send another signal.
What is refractory period?
The type of transport that allows neurotransmitter to exit the cell/
What is exocytosis?
This part of the neuron encapsulates the axon and allows for faster neural signaling.
What is the myelin sheath?
The major endocrine gland. A pea-sized body attached to the base of the brain, is important in controlling growth and development and the functioning of the other endocrine glands.
What is the pituitary gland?
Dopamine is cleared through this type of clearance mechanisms.
What is reuptake, enzyme degradation, and diffusion?
