The three microscopic components of muscle cells that are not found in other types of cells Introduction: The muscle cells are also known as Myocytes. They are long, tube-shaped cells. These cells form the muscle tissue. The muscle cell is composed of myofibrils, which are made up of repeated units of sarcomeres in the sarcoplasm, along with sarcoplasmic reticulum surrounded by sarcolemma. The muscle cells are of three different types: smooth, cardiac and skeletal muscle cells. The skeletal muscle fibers are large, striated cells with multiple nuclei. The smooth muscle cells are elongated, spindle-shaped and non-striated. The cardiac muscle cells are striated, contain one-two nuclei and are separated from intercalated disk and form an intercalating network.

Summary Introduction

To identify:

The three microscopic components of muscle cells that are not found in other types of cells

Introduction:

The muscle cells are also known as Myocytes. They are long, tube-shaped cells. These cells form the muscle tissue. The muscle cell is composed of myofibrils, which are made up of repeated units of sarcomeres in the sarcoplasm, along with sarcoplasmic reticulum surrounded by sarcolemma. The muscle cells are of three different types: smooth, cardiac and skeletal muscle cells.

The skeletal muscle fibers are large, striated cells with multiple nuclei. The smooth muscle cells are elongated, spindle-shaped and non-striated. The cardiac muscle cells are striated, contain one-two nuclei and are separated from intercalated disk and form an intercalating network.

Using information from the primary literature (several references have been provided as a starting point below) please answer the following question: Based on your review of the literature on rewilding, what are the major scientific pros and cons for rewilding? Please note that the focus of this assignment are the (biological) scientific issues associated with rewilding. As will be discussed in class, there are a number of non-scientific issues involved or implicated in rewilding, all ultimately affecting the public acceptability of rewilding. Although these issues are important – indeed, critical – in this assignment you should focus on the biological science issues and questions. Details: You must enumerate at least two pros and at least two cons. Your answer should be no more than 500 well-chosen words, excluding references. Think carefully about how best to organize and structure your answer. Aim for high information density: say a lot, but say it succinctly. Recall Nietzche’s…
