Neuron A has very long axons, whereas neuron B has short axons. However, both of them can send impulses over the same period of time. The difference in the structure of the two neurons is….
Axon B is covered with myelin sheath, while axon A is not
Axon A is covered with a thin myelin sheath, while axon B is covered with a thick myelin sheath
Axon A is covered with myelin sheath, while axon B is not
Axon A is completely coated with myelin sheath to the end of the axon, while axon B does not have myelin sheath
Axon A is covered with myelin sheath with Ranvier's nodes, while axon B is completely coated with myelin sheath to the end of the axon.
Neurons consist of three parts, among others ...
Pericaryon, dendrite, and impulse
Pericaryons, axons, and dendrites
Dendrites, ganglion and nucleus
Pericaryons, axons and nucleus
Impulses, axons, and dendrites
Between two neurons there is a relationship between neurons that play a role in impulse transmission. The following are true statements regarding the relationship, except ...
The impulses that come can be continued or transmitted
Between the two neurons there is a synaptic gap
The impulse propagates back and forth
Impulses are transmitted from presynaptic neurons to postynaptic neurons
Impulse transmission requires conducting substances called neurotransmitters
Below that does not include the influence of sympathetic nerves on the work of organs, namely ...
Inflate the bladder
Speed up heart rate
Speed up the digestive process
Dilates the pupil
Reducing the diameter of the vessels
The part of the image marked with an X serves to…
Feeding neurites
Accelerate the passage of impulses
Protects neurites from damage
Forward impulses to other nerve cells
1. Dendrites receive neurotransmitters from the axons of other cells
2. Neurotransmitters will be released and then returned to other nerve cells
3. The impulses travel along the axon membrane to the end of the nerve cell
4. As a result of impulses, there is a change in the charge on the inner membrane and outer membrane of the axon
5. The sequence of the flow of electrical impulses in human nerve cells is correct, namely ...

Reflex tests are often carried out by hitting a soft object suddenly under the knees so that the patient unconsciously moves forward. The movement involves a reflex arc starting at the knee and then working its way down ...

Sufferers have difficulty walking and often walk unsteadily where their arms do not swing according to their steps. The face of the sufferer becomes less expressive because the facial muscles to form an expression do not move. The name of the disease based on these symptoms is ...
Epilepsy
Parkinson
Transection
Night blindness
Eczema
Look at the following picture!
Nicotine affects the work of the nervous system in a way ...
Increase inhibitory neuron activity
Stimulates dopamine-releasing VTA neurons
Decreases inhibitory neuron activity
Blocking dopamine receptors on the post-synaptic membrane
Increase the dopamine concentration at the synaptic cleft
