What is synapse?
Release of neurotransmitters occur from the presynaptic to the postsynaptic cells.
Release of neurotransmitters occur from the postsynaptic to the presynaptic cells.
Release of enzyme occur from the presynaptic to the postsynaptic cells.
Release of enzyme occur from the postsynaptic to the presynaptic cells.
How can we recognize the type of synapse?
Neurotransmitter
Enzyme
Receptor
Site of synapse
Changes of transmembrane potential allow neural function. The ECF contains high concentration of .. ?
Na+
Cl-
K+
Protein
Changes of transmembrane potential allow neural function. The ICF contains high concentration of .. ?
Na+
Cl-
K+
Protein
Why does ICF has excess positive (+) charges?
Protein cannot cross cell membrane, Na+ enter ICF with Na+ channel = more +ve charges
Protein cross cell membrane, Na+ enter ICF with Na+ channel = more +ve charges
Cl- cross cell membrane, Na+ enter ICF with Na+ channel = more +ve charges
Cl-, Protein, K+ and Na+ filled the ICF = more +ve charges
Neurons can produce ... ?
Excitement
Satisfaction
Enthusiasm
Anticipation
Neuron will change signals caught by receptor to impulses. These impulses are present as electrical charges. Choose the correct characteristic of impulse.
