- Please answer this following questions in your own words: Question 1: Identify the main tissue types that could be found in the human body and discuss their roles? Question 2: can you Identify the three types of muscle tissue and their function? and Identify the classes of cells that make up nervous tissue?1. Discuss how microtubules are arranged and how they interact to promote movement. 2. Discuss how the components of muscle cells enable movement in muscles. Please answer 1 and 2. Thank youSkeletal, smooth, and cardiac muscle are similar in that they all _____. A are divided into motor units B require calcium in order to contract C undergo mitosis frequently to replace dead or damaged cells D have small round cells connected by gap junctions

If this organ is destroyed the secondary…Which muscle type has the most elaborate connective tissue wrappings? Please explain. What do striated mean relative to muscle cells? Please explain further.Can cardiac muscle exhibit (normally or under experimental conditions) summation or complete tetanus as does skeletal muscle? Why not? (highlight the main answer)
- Which of the following are aspects of the structure of skeletal muscle? Select all that apply. --They are cylindrical cells called muscle fibers that have multiple nuclei. --Skeletal muscle has more mitochondria than other types of muscle cells. --The muscle fibers parallel one another and have a striated appearance. --Cells are branched or unbranched with single nuclei. --Each fiber contains stacks of many units of contraction and protein filaments.What is the principal difference between the way cardiac muscle and smooth muscle form and the way skeletal muscle forms?Muscle Tissue 1. List the three types of muscular tissue. 2. List the characteristics of skeletal muscle. 3. List the characteristics of smooth muscle. 4. List the characteristics of cardiac muscle.
- One of the major questions of regeneration is whether the cells keep a “memory” of what they had been. In other words, do new muscles arise from old muscle cells that dedifferentiated, or can any cell of the blastema become a muscle cell?Calmodulin is found in smooth muscle cells and performs a similar function to troponin in striated muscle fibers. However, calmodulin not only gets activated by Ca2+ but also slows the release of Ca2+ from the sarcoplasmic reticulum. How might this difference relate to the different kinds of contractions smooth muscles do in comparison to striated muscles?In cardiac muscle, which ion serves both to depolarize the cells and as the essential link to myocyte contraction (the troponin/tropomyosin part)? a-Na+ b-Ca+ c-Ca2+ d-Cl-
