General Instructions

In the following activity, we will present you with four actions carried out by the human body. You must explain what each one consists of by following the corresponding instructions and items provided.

Step 1 - Review

1st Scenario:

A woman is on her way to work. She walks, begins to accelerate her step, and realizes that, suddenly, she starts running to reach on time. At this time, her nervous system begins to generate an answer.

2nd Scenario:

Damage to specific regions of the cerebral cortex, such as through a stroke, can result in specific losses of function. A 65-year-old man suffers from high blood pressure. He stopped taking his medication, and the blood vessels in his brain collapsed, and he suffered a stroke. In the MRI, the doctor noticed two damaged regions in his brain, the Temporal and the Occipital. 

3rd Scenario:

Following a motorcycle accident, the victim loses the ability to move the right leg but has normal control over the left one, suggesting a hemisection somewhere in the thoracic region of the spinal cord. 

4th Scenario:

The cardiovascular center is responsible for regulating the heart and blood vessels through homeostatic mechanisms. 

Step 2 - Respond

1st Scenario:

• 5 keywords that you will use in your explanation paragraph.
• List the organs generally involved to perform the actions described. 
• Explain what answer was generated by the nervous system when the woman began running. Include an example of each type of tissue that is under the control of the nervous system. (maximum 100 words for the explanation)

2nd Scenario:

• 5 keywords that you will use in your explanation paragraph.
• List of the organs involved in the loss of functions action.
• Explain which functions would probably be lost by a stroke in the temporal lobe and which in the occipital lobe. (maximum 100 words for the explanation)

3rth Scenario:

• 3 keywords that you will use in your explanation paragraph.
• List of the organs involved in the loss of functions action.
• Explain what sensory deficits would be expected regarding touch versus pain. Explain your answer. (maximum 100 words for the explanation)

4th Scenario:

• 3 keywords that you will use in your explanation paragraph.
• List of the organs involved in the loss of functions.
• Explain what tone each component of the cardiovascular system is.
• What connections does the cardiovascular center invoke to keep these two systems in their resting tone? (maximum 100 words for the explanation)

Step 3: Share

Step 4: Interact

OPTIONAL Step 5: Interact (10 minutes)
