Actin filaments, usually in association with myosin, are responsible for many types of cell movements. Myosin is the prototype of a molecular motor —a protein that converts chemical energy in the form of ATP to mechanical energy, thus generating force and movement. The most striking variety of such movement is muscle contraction, which has ... Cardiac muscle (or myocardium) makes up the thick middle layer of the heart. It is one of three types of muscle in the body, along with skeletal and smooth muscle. The myocardium is surrounded by a thin outer layer called the epicardium (AKA visceral pericardium) and an inner endocardium. Coronary arteries supply to the cardiac …The answer is a, one nucleus, which is located near the center of the smooth muscle cell. 2. Smooth muscle contains striations. a. True. b. False. The answer is b, false. Unlike skeletal and cardiac muscle tissue, smooth muscle tissue does NOT contain striations (stripes), due to its lack of sarcomeres.1. INTRODUCTION. Striated muscle is composed of two major muscle types—skeletal and cardiac. While the cardiac (heart) muscle functionally represents a set of self‐stimulating, non‐fatiguing muscle cells with an intermediate energy requirement, skeletal muscle represents a set of innervated, voluntary muscle cells that exhibit fatigue with high energy requirements (e.g., muscles of the ...Organelles of a skeletal muscle cell contain the same organelles as other animal cells, with the addition of myofibrils.
