The left parietal lobe cortex

/0 Comments/in /by
A 71-year-old woman had loss of consciousness persisting for over an hour. When she becomes arousable, she cannot speak nor move her. right arm. A cerebral angiogram reveals an occlusion to her left middle cerebral artery. Three months later, a computed tomographic (CT) scan showed a large 5 cystic area in her left parietal lobe cortex. This CT finding is most likely the consequence of resolution from which of the following pathologic cellular events?
a. Atrophy
b. Liquefactive necrosis
c. Caseous necrosis
d. Coagulative necrosis
e. Apoptosis

The rare Andean anteater

/0 Comments/in /by

The limb depicted below is from the rare Andean anteater. It feeds by pushing over ant hills and consuming the delicious larvae underneath. To do this, it needs to generate an out force at its claw of 50(newtons).

Assume the following:
the limb has the proportions shown below
the limb muscle generates this force with the joint angle and muscle line of action shown
the muscle generates a force of 4o 2 (i.e. 40 Newtons of force per square centimeter of physiological cross-sectional area)
the entire length of the whole muscle is composed of contractile tissue (i.e. there is no tendon – we’ll talk about tendons later)
Don’t have ruler, measured

What cross sectional area of muscle is required, assuming that the muscle fibers run parallel to the long axis of the muscle? (Note: Use a ruler, and measure in centimeters).

Which of the following best summarizes the research on long-term endurance exercise?
Research shows that in terms of the health benefits of exercise, more is always better in terms of the overall protective effect.
There are potential health risks including coronary artery calcification, a risk factor for cardiovascular disease

The general nervous system depressant

/0 Comments/in /by

Ethanol is a general nervous system depressant, and among the neurons inhibited by ethanol are neurosecretory cells of the hypothalamus. Using your knowledge of hormones released by the posterior pituitary, how would ethanol consumption affect urine volume, the urine’s osmolarity, and the blood’s osmolarity? Explain your answers, including the hormone involved.

You are at your favorite restaurant where you order their best dish, a pizza with anchovies. Before it arrives at your table, you can smell its distinct aroma. What is the process of olfaction? Use 23.2 Olfaction and 23.3 Olfactory Pathway to help you. You next take a bite of this odiferous confection upon being placed in front of you. You then taste its deliciousness. How does the process of tasting work and what are the five kinds of taste?

Mitral valve regurgitation is a condition where the mitral valve doesnt close tighlty and permits some backflow of blood, which can reduce the effciency of the heart. In a person with mitral valve regurgitation, the backflow of blood would be into which chamber of the heart?

Examples of homeostatic control systems

The human body uses a variety of homeostatic control systems to keep its internal environment relatively constant around an optimal level. This stability is essential for survival, so you should not be surprised to find e in all of the major body systems.
The following illustration highlights the general workings and components of a homeostatic control system typically found in the human body. Starting at the first arrow (labeled 1), complete the illustration by using the dropdown menus provided.

The effects of the hormones on the body

Describe the effects of the hormones on the body to explain how calcitonin and parathyroid hormones maintain calcium levels in the body. Be very specific. You may draw two detailed flow diagrams instead of writing a paragraph if you choose, one for each hormone. Your textbook has examples as does Google (make sure you use a valid scientific source).
