Drug addiction has reduced the number of receptors in the addicts neural synapses. How will this affect signal transduction at the synapse?
Answers
Synapse is a specialized contact between nerve cells (or nerve and other excitable cells), which ensures the transmission of excitation while maintaining its informational significance. With the help of synapses, nerve cells are combined into nerve networks that process information. The relationship between the nervous system and peripheral organs and tissues is also carried out with the help of synapses.
Synapse classification
According to the morphological principle, synapses are divided into:
• neuromuscular (the axon of a neuron is in contact with a muscle cell);
• neuro-secretory (the axon of the neuron is in contact with the secretory cell);
• neuro-neuronal (the axon of a neuron is in contact with another neuron):
• axo-somatic (with the body of another neuron),
• axo-axonal (with the axon of another neuron),
• axo-dendritic (with the dendrite of another neuron).
According to the method of transmission of excitation, synapses are divided into:
• electrical (excitation is transmitted by means of electric current);
• chemical (excitation is transmitted with the help of a chemical):
• adrenergic (excitation is transmitted with the help of norepinephrine),
• cholinergic (excitation is transmitted with the help of acetylcholine),
• peptidergic, NO-ergic, purinergic, etc.
According to the physiological effect, synapses are divided into:
• excitatory (depolarize the postsynaptic membrane and cause excitation of the postsynaptic cell);
• inhibitory (hyperpolarize the postsynaptic membrane and cause inhibition of the postsynaptic cell).
The terminal part of the axon (synaptic ending), approaching the innervated cell, loses its myelin sheath and forms a small thickening at the end (synaptic plaque). The part of the axon membrane that contacts the innervated cell is called the presynaptic membrane. The synaptic cleft is a narrow space between the presynaptic membrane and the membrane of the innervated cell, which is a direct continuation of the intercellular space. The postsynaptic membrane is the portion of the innervated cell membrane that contacts the presynaptic membrane through the synaptic cleft.

An earthquake is a natural disaster that includes the violent shaking of the ground provoked by the sudden movement of rock materials.
What are the three elements of command and management?The three elements of command and management include an incident command system, a multi-agency coordination system, and public information.
An incident command system is a standardized strategy for the command, control, and coordination of emergency response. It allows the affected individual to fulfill their needs or demands which were taken by natural disasters. A multi-agency coordination system works synergistically to provide for all the needs of affected people. This system wants to heal the problem or situation caused by the earthquake. It supports and facilitates resource tracking and supply. Public information deals with summarizing the threat that happened by the earthquake publicly. It reveals the actual severity of any natural disaster only by words. It kept all the information, assignment, and documents related to the earthquake for future availability.Therefore, an earthquake is a natural disaster that includes the violent shaking of the ground provoked by the sudden movement of rock materials.
