Dani Brain 1 Flashcards
How much of the total oxygen of the body does the brain consume
20%
How much of the total body glucose does the brain consumes
About 25%
How much of the body does the brain mass
2%
What does neuron sends between each other
Neurotransmitters
How does the space between the neurons called
Synaptic gap or synaptic cleft
Which part of the neuron is the connection point
Synapse
What are the glial cells
Non-neuron cells that support neurons and provide them nutrients
which is the most abundant glucose transporter in the brain
Glut 3
Which type of astrocyte are existed?
Fibrous and protoplasmic
Where does the protoplasmic astrocyte are located
In the gray matter
Where does the fibrous astrocytes are located
At the white matter
How many subtypes of tight exist
10
Did the Astrocytes evolved through evolution
Yes
Which brain cells did Albert Einstein had more than an average person
Astrocytes
Did the behavior of a mouse changed after he was transplanted with human brain
Yes
For what action does the astrocytes responsible for
Sending neurotransmitters send blood vessels express plasma membrane transporters
Synapse function
Which types of blood brain barrier there are
- In the blood vessels
- Endothelial cells
- pericyte cells
Which protein components existed in the tight junction
Claudine , occluding and adhesion molecules like Cadherin
Which glucose transport facilitates the neuronal glucose uptake in the brain
Glut 3
Which metabolic process is unique to astrocytes
Glycolysis that ends up with Lactet production
Which metabolic product is unique for astrocytes in different way from the other brain cells
Glycogen
Which cognitive function does the glycolgen is required
Conversion from short term memory to long-term memory
Which product does the glycogen transform into in order to create long-term memory
Lactate
How astrocyte function to glutamate That being transported from one neuron to other
Take the majority of the glutamate and convert it to glutamine
