The type of muscle tissue that is least impacted by the change in extracellular Ca 2+ concentration during contraction. Introduction: The increased amount of the Ca 2+ promotes the formation of actin-myosin complex in the muscle cells. Therefore the Ca 2+ concentration of the cytosol should always be low. Muscle fibers would fail to relax if the concentration of the Ca 2+ remains increased. The muscle tissue that would be least impacted by the increased concentration of Ca 2+ in the extracellular space in the contraction state, is the skeletal muscle tissues.

Summary Introduction

To determine:

The type of muscle tissue that is least impacted by the change in extracellular Ca²⁺ concentration during contraction.

Introduction:

The increased amount of the Ca²⁺ promotes the formation of actin-myosin complex in the muscle cells. Therefore the Ca²⁺ concentration of the cytosol should always be low. Muscle fibers would fail to relax if the concentration of the Ca²⁺ remains increased. The muscle tissue that would be least impacted by the increased concentration of Ca²⁺ in the extracellular space in the contraction state, is the skeletal muscle tissues.

Discussion entries must be at least 250 words to fulfill the assignment requirements. You must complete your entry before you will be able to see the responses of other students. Responses to other students are encouraged but not required. Grading for discussion entries will be based on application of course concepts, proper grammar, and correct punctuation. Read one the attached article and explore the Human Development Index (https://hdr.undp.org/data-center/human-development-index#/indicies/HDI). In your opinion, is the Human Development Index a good measure of the well- being of the people of a nation? Are the items measured in the HDI valid and relevant in the modern global economy? How are they related to the political economy of a nation? The attached articles propose some alternative measures of well-being. In your opinion, are there other measures of well-being that might be better alternatives to the items in the current HDI?
