Answer:
Sensory transduction.
Explanation:
Sensory transduction may be defined as the process by which sensory stimulus are transformed in the body. The receptor cell is mainly involved in the sensory transduction process.
The sensory receptor cell like a light or an odor is converted into the electrical signal by the process of signal transduction. The information is then conveyed to the nervous system in the form of electrical signals.
Thus, the correct answer is signal transduction.
The right answer is the second one
I think that they both measure energy
Answer:
The correct option is: <em>a deficiency of dopamine in the substantia nigra.</em>
Explanation:
The substantia nigra is the principal site involved in the physiopathology of Parkinson´s disease.
Cells from this area degenerate and die progressively causing important degeneration in the central nervous system. The cells that die -with no known reason- are those that produce dopamine and proportionate dopaminergic innervation to the encephalon. In fact, almost all the symptoms exhibited by patients with the disease can be explained by the lack of dopamine in the substantia nigra.
This area uses the neurotransmitter to communicate neurons from the base ganglia. Ganglia are responsible of modulating and modifying movements.
The nigrostriatal system participates in planning and automatic execution of learned movements. When the ganglia activity decreases, so it does the amount and velocity of movements, something typical of the disease.
