Easy
Basic unit of nervous system
Neuron
How neuron communicate with each other?
Electrically and chemically
Common neurotransmitter
Acetylcholine
Function :
-Nourish cells
-Insulate axons
-Regulate extracellular fluid
- Replenish certain group of neurons
Name this cell
Glia cell / Glial cell
Largest continent
Asia
Resting Potential charge (mV)
-70 mV
3 stage of nervous system
Sensory input, integration, motor output
Action potential generated in
Axon Hillock
Lobe that functions for decision making
Frontal lobe
Saddest death in Demon Slayer (yang belum tengok tutup mata) (dalam anime bukan manga)
RENGOKUUUUUUUU
Myelin sheath is produced by
- oligodendrocytes in central nervous system
- schwann cell in peripheral nervous system
The forebrain part is formed of
Olfactory bulb and cerebrum
Neurotransmitter is release via _______ in synaptic cleft
exocytosis
Where are neurotransmitter receptors located?
The postsynaptic membrane
When you cook or eat a potato, the potato are ______
Still alive
An electrical signal that propagates (travels) along the membrane of a neuron or other excitable cell as a nongraded (all-or-none) depolarization.
Action potential
A transmembrane protein channel that allows a specific ion to diffuse across the membrane down its concentration or electrochemical gradient.
Ion channel
The potential that an excitable cell membrane must reach for an action potential to be initiated.
Threshold
________ opens when SPECIFIC neurotransmitter binds
Ligand gated channels
Abang Gusion MLBB
Aamon
Refractory period function
-Ensure signals travels in pne direction
-Prevents neuron from firing repeatedly due to low level stimulation
Saltatory conduction happens in
Myelinated fibers
Transmission of information from neurons to other cells occurs at
Synapses
Describe all-or-none response (this is related to threshold)
-threshold reached, action potential happens
-threshold not reached, action potential NOT happen
