Explanation:
Sensory (or afferent) neurons, <em>located in the central neuron system (brain and spinal cord)</em>, are a special kind of neuron that carries <em>electrical signals (impulses) from receptors or sense organs to the CNS</em>. In this process, a type of stimulus is transformed, via their receptors, into action potentials or graded potentials in a process known as sensory transduction.

By volume, oxygen is the second most abundant element in the hydrosphere and troposphere. The troposphere is the lowest part of Earth's atmosphere which is nothing but air, and the hydrosphere is made up of the Earth's water which is full of oxygen at any given moment.
Answer:
The hormone is seretonin.
Explanation:
Seretonin is a hormone that is synthesized from the hydroxylation of amino acid tryptophan resulting in the formation of 5-hydroxytryptophan which further undergo de carboxylation to form seretonin.
Seretonin is found in both myentric neuron and seretogenic neuron.Seretonin helps to control mood,desire for food and sleep.
Selective seretonin reuptake inhibitors are used as antidepressent that interfere with the re absorption of seretonin thereby maintaining high level of seretonin in the synapse.
