The correct answer is C. Arches.
Explanation
The arch is the name by which a type of semicircular structure is known, which is used as a support for buildings because it provides great stability to them, due to the distribution of the load that allows it to support large amounts of weight. This form of architecture developed in ancient civilizations like Mesopotamia. However, its greatest use was in ancient Rome, where it was used in different structures with domestic functions such as sewers, aqueducts and bridges; and larger buildings such as theaters and the monumental Roman Coliseum. So, the correct answer is C. Arches.
Answer:
the effects of neurotransmitters released from either sympathetic or parasympathetic postganglionic neurons may be stimulatory or inhibitory
Explanation:
The effects are based on two aspects: when excitation occurs a stimulus makes an increase of chances that neurons will engage in action.
On the contrary, <em>when inhibition is preferred it means that the likelihood that neurons will act together is lessened so neurotransmitters make nerve cells process and transmit information through electrical and chemical stimulus.</em>
An <em>increase of activity is done by the excitation and a decrease or cessation of activity is done when inhibitory neurotransmitters are present.</em>
Simply put, neurons act based on the surrounding chemicals that are present, they are the neurotransmitters.
The exchange of information between neurons is always enabled and regulated by these substances. They help life-essential processes: make the heartbeat, cause lungs to keep breathing and help in stomach digestion.
<u>Of course, when we sleep, are awake and study different levels of neurotransmitters are present.</u>
