          Question 4.
          \nRed muscle fibers have greater capacity to do work for a prolonged period where as white muscles suffer from fatigue after a short time. Give reason.
          \nAnswer:
          \nRed muscle fibers are red in colour due to the presence of large amount of myoglobin. Myoglobin is an oxygen storing pigment. These muscle also contain plenty of mitochondria which can utilise the large amount of oxygen stored in them for ATP production.<\/p>\n

          So red muscle fibers have greater capacity to do work for a prolonged period. White muscle fibers possess very less quantity of myoglobin and mitochondria.<\/p>\n

          Question 5.
          \nShoulder joints are not very stable. But they are freely movable. Give reason?
          \nAnswer:
          \nShoulder joints are freely movable joint or synovial joint. In this type of joint there is presence of a fluid filled synovial cavity between the articulating surfaces of the two bones. Such an arrangement allows considerable movement.<\/p>\n

          Question 6.
          \nName the types of joint between the following.<\/p>\n

            1. Pivot joint<\/li>\n
            2. Fibrous joint<\/li>\n
            3. Saddle joint<\/li>\n

              1. What do you meant by the term floating ribs?<\/li>\n
              2. What are true ribs?<\/li>\n<\/ol>\n

                Answer:<\/p>\n

                  \n
                1. Last 2 pairs of ribs are not connected ventrally to the sternum. These ribs are called floating ribs.<\/li>\n
                2. First seven pairs of ribs are called true ribs. Dorsally, they are attached to the thoracic vertebrae and ventrally connected to the sternum with the help of hyaline cartilage.<\/li>\n<\/ol>\n
