Schwan cells are found inA. Myelinated nerve fibresB. Unmyelinated nerve fibresC. Both A and BD. None of the above |
|
Answer» Correct Answer - C There are two types of axons, namely, myelinated and non-myelinated. The myelinated nerve fibres are enveloped with Schwann cells, which form a myelin sheath around the axon. The gaps between two adjacent myelin sheaths are called nodes of Ranvier. Unmylinated nerve fibre is enclosed by a Schwann cell that does not form a myelin sheath around the axon. |

Answer» Correct Answer - b During resting membrane potential, `Na^(+)` ions are more on the outer side of membrane due to `Na^(+)-K^(+)` ion pumps: (b) Action potential lasts only for very short time and `Na^(+)` ions are more on the inner side of membrane, (c) During depolarization, `Na^(+)` developing positive charge on inner side of plasma membrane, (d) during replarization, `Na^(+)` ion channel get closed and `K^(+)` ion channels open leading to effux of `K^(+)` moving it outerside of membrane. |

Assertion : The function of muscles, lungs, heart, blood vessels, kidney and other organs are coordinated while performing physical exercise. Reason : In our body the neural system and the endocrine system jointly coordinate all the activities of the organs so that they function in a synchronised fashion.A. If both assertion and reason are true and the reason is the correct explanation of the assertion.B. If both assertion and reason are true but reason is not the correct explanation of the assertion.C. If assertion is true but reason is false.D. If both assertion and reason are false. |
|
Answer» Correct Answer - A The functions of the organs/organ systems in our body must be coordinated to maintain homeostasis. Coordination is the process through which two or more organs interect and complement the functions of one another. For example, when we do physical exercises, the energy demand is increased for maintaining an increased muscular activity. The supply of oxygen is also increased. The increased supply of oxygen necessitates an increase in the rate of respiration, heart beat and increased blood flow via blood vessels. ltBrgt When physical exercise is stopped, the activities of nerves, lungs, heart and kidney gradually return to their normal conditons. Thus, the functions of muscles, lungs, heart, blood vessels, kidney and other organs are coordinated while performing physical exercises. |
