Why does the shoulder joint have more freedom of movement than any other joint of the body? The entire process of coordinated, voluntary, muscle contraction is summed up as excitation-contraction coupling. Why are these two things coupled, and what, specifically, is responsible for bring excitation and contraction together i
1. Why is knowing the patient is at risk for bacterial endocarditis important to the emergency room workers? 2. Although a bone density scan is the test that verifies a diagnosis of osteoporosis, what results from the other tests (chemistry profile, thyroid studies, urinalysis, and CBC) would contribute to the diagnosis?
I need some help in these questions on joints, their movements and some of the homeostatic imbalances in diseases: 1. Identify a homeostatic imbalance (disease) of a joint or joints; 2. Describe the joint by its structural and functional classification; 3. Describe the type of movement that joint or joints exhibit; 4. Descri
The endocrine system plays an important role in our ability to handle stress. Hormone release associated with the stress response can help us to survive and handle crisis situations. However, chronic stress can result in unregulated release of stress hormones that can have negative effects on the brain and our immune systems.

The human body is truly remarkable and is designed to function effectively. Organs are important structures composed of different tissues that facilitate specific functions within the body. Organs function as part of an integrated group of structures known as organ systems. These organ systems form the organizational units that
