26) Select the correct statement about the function of myocardial cells. A) The entire heart contracts as a unit or it does not contract at all. B) Each cardiac muscle cell is innervated by a sympathetic nerve ending so that the nervous system can increase heart rate.Select the correct statement about bone. A) Bone stores, but does not release, inorganic salts. B) Bone cells (osteocytes) are dead in mature bone. C) Bone is a very metabolically active tissue. D) Elderly people cannot rebuild bone.Select the CORRECT statement about the function of myocardial cells. The entire heart contracts as a unit or it does not contract at all. Each cardiac muscle cell is innervated by a sympathetic nerve ending so that the nervous system can increase heart rate. The refractory period in skeletal muscle is much longer than that in cardiac muscle.Cardiac muscle tissue or myocardium forms the bulk of the heart. The heart wall is a three-layered structure with a thick layer of myocardium sandwiched between the inner endocardium and the outer epicardium (also known as the visceral pericardium). The inner endocardium lines the cardiac chambers, covers the cardiac valves, and joins with the endothelium that lines the blood vessels thatDead cells provide mechanical strength as easily as live ones, and need less maintenance. 3. Select the longest animal cell among following. (a) Nerve cell (b) Muscle cell (c) Liver cell (d) Goblet cell Ans : (a) Nerve cell The longest animal cell is nerve cell. 4. Given are some differences between the tissues of plants and animals.
