In a sensory pathway, third-order neurons run from the thalamus to the sensory cerebral cortex.
Thalamus is a gray matter located in the center of the brain. It is the main center for the processing of all the signals that are transmitted to the different parts of the body. However, the thalamus does not control the signals in response to smell.
The cerebral cortex is the outermost layer of the brain. It is responsible for the processing of functions like language, thinking, reasoning, decision-making, etc. There are three functional areas: motor areas, sensory areas, and association areas.

Answer: There should be concern because zoonotic diseases passes from an animal or insect to a human very easily, and although they do not always represent a danger, they can cause serious symptoms and even death.
Explanation:
Zoonotic diseases are caused by microorganisms such as bacteria, virus, parasites and fungi, and they can be transmitted between animals and humans. Some examples of zoonotic diseases are Brucellosis, Anthrax and Rocky Mountain Fever (rickettsiosis)
Sometimes, people with zoonotic infections can get very sick and have symptoms such as fever, diarrhea, muscle pain and others. While in other cases, people may have no symptoms and never get sick, without representing a risk
. <u>Besides being important because they can make many people sick, we have to take into account that the way of transmission or propagation can be very simple.</u> Food can be a source of zoonotic infections, for example when farm animals re infected with parasites and these animals are consumed as food. Another example is when people get trichinosis by eating undercooked meat, or consuming fruit without washing it properly, or raw meat from animals infected with the Trichinella parasite. Also, people can get the parasites swimming in a lake if they accidentally swallow water contaminated with the feces of infected animals. Besides, pets can have parasites and pass them on to people, and wild animals can also have infection from parasites that can infect people.
Therefore, we must be concerned about zoonotic diseases, since they can be transmitted very easily from animals to humans, and although they do not always represent a danger, they can cause serious symptoms and even death.
