Overall, how has science impacted human health?
mixas84 [53]

Answer:

The correct answer is: <em>C. Increased average lifespan to 78 in the US.</em>

Explanation:

Science has impacted human health by increasing the average lifespan to 78 in the US. Over the last couple of decades, the life expectancy of Americans has increased significantly than what it was 200 years ago. This can be attributed to:

1. Vaccinations- Since the invention of vaccinations, diseases such as tuberculosis, cholera and polio which were major causes of death 200 years ago have virtually been eradicated in the US.

2. Abundant and safer foods available- Commercial and large scale farming has made a wide variety of nutritious foods easier to obtain.

3. Improved sanitation- Safer drinking water, sewage treatment and stricter food inspection has significantly reduced the rate of illnesses due to poor hygiene and sanitation.  

In these ways, science has impacted human health by increasing the average lifespan to 78 in the US.

Anika [276]

The amygdala is thought to control defensive behavior via outputs from the central nucleus of the amygdala

What does the Amygdala do?

It is crucial in processing and regulating emotional reactions. Especially important in strong emotional reactions such as fear and anger

What does the amygdala control?

The amygdala is commonly thought to form the core of a neural system for processing fearful and threatening stimuli , including detection of threat and activation of appropriate fear-related behaviors in response to threatening or dangerous stimuli.

Central nucleus of Amygdala :

The central nucleus of the amygdala (CeA) has been traditionally viewed in fear conditioning to serve as an output neural center that transfers conditioned information formed in the basolateral amygdala to brain structures that generate emotional responses.

What does the central nucleus consist?

The central nucleus of the amygdala (CeA) is primarily composed of GABAergic interneurons which are finely controlled through glutamatergic neurotransmission and signaling. The CeA can be divided into the medial (CeM) and lateral (CeL) divisions
