In a study to determine whether trans-fat consumption was associated with heart disease mortality, researchers studied the per capita consumption of trans-fats and the number of deaths per 100,000 population. They obtained this information for all 50 states in the US and created a plot showing the relationship between trans-fat consumption and heart disease mortality for each state. Use this information to answer the Questions 12 and 13.

Fred and Mary were working in the library and were asked to shift textbooks from one shelf to another. Fred asked Mary to hold out her hands so he could stack several books on her arms to carry multiple books at once. Fred noticed when he placed a textbook on Mary’s arms they would extend downward slightly for a moment and then return quickly to the original position, this happened with each additional textbook he added. Mary was surprised by this as she didn’t feel as if she was voluntarily restoring her arm position. When Fred placed a 5th very heavy textbook onto the stack in Mary’s arms her arms relaxed and all the textbooks fell to the floor, Mary insisted she didn’t drop the books purposefully but did feel the load was becoming too heavy for her to maintain her arm position.

a) Which reflex is first being elicited as Fred adds each book to Mary’s arms to enable Mary to maintain her arm position? Provide a description of this neural reflex pathway, including the stimulus, receptor, neural pathway, effector and response. Include or draw a diagram. (6 points worth)

b) As Fred added the 5th textbook the increased load caused Mary’s arms to relax. Which sensory receptor was activated here and what is this detecting in the muscle? How does this result in Mary dropping the books? (4 points worth)

A patient comes into the ER after she was attacked. She is experiencing difficulty breathing after she was stabbed in the thorax. Scans show fluid in the thoracic cavity through a lesion in the lung; in short, a hemopneumothorax. Explain the pressure gradients that would allow air and blood to enter the thoracic cavity in the first place. What will happen to this patient without medical intervention? Explain each step of her imminent demise.
