Flipper
a leg spin delivery with under-spin, so it bounces lower than normal, invented by Clarrie Grimmett. Floater
a delivery bowled by a spinner that travels in a highly arched path appearing to float in the air. Fly slip
a position deeper than the conventional slips, between the slips and third man. Follow on
a team which bats first in the second innings, after having batted second in the first innings, is said to have followed on. The captain of the team batting first in the first innings may direct the team batting second to follow on if it leads by a certain margin after the first innings; this margin is currently 200 runs in a five-day game, and 150 runs in a three- or four-day game. Follow through
a bowlers body actions after the release of the ball to stabilise their body. Footmarks
On a grass pitch, the bowler creates a rough patch where they lands their foot and follow through after delivering the ball. The rough patch can become cratered and becomes more abrasive as the match continues and more players step on it. The abrasive surface means that the ball will increasingly grip more if it lands in the footmarks. Bowlers, particularly spinners, will aim the ball there as it will turn more sharply, and is more likely to get irregular bounce from such areas, making it more difficult for the opposition batsmen.
Brody myopathy, also called Brody disease, is a rare disorder that affects skeletal muscle function. BD was first characterized in 1969 by Dr. Irwin A. Brody at Duke University Medical Center. Individuals with BD have difficulty relaxing their muscles after exercise. This difficulty in relaxation leads to symptoms including cramps, stiffness, and discomfort in the muscles of the limbs and face. Symptoms are heightened by exercise and commonly progress in severity throughout adulthood. Signs and symptoms
Symptoms include stiffness and sometimes muscle cramping after exercise and especially when exposed to cold. The most commonly affected muscles are in the arms, legs, and eyelids. Individuals with Brody myopathy also sometimes experience weakness, myalgia, and rhabdomyolysis. Cause
Most cases of BD are inherited through autosomal recessive mutations in ATP2A1,  where each copy of the affected individuals gene contain a mutation. The gene involved in BD encodes the fast-twitch skeletal muscle ATPase, SERCA1. SERCA1 is a protein pump that uses ATP to pump Ca2+ ions from the cytosol to the sarcoplasmic reticulum in skeletal muscle. In those with BD, SERCA1 pumps are unable to effectively move Ca2+ across the membrane, leading to increased levels of cytoplasmic Ca2+. Increases in cytoplasmic Ca2+ levels interfere with muscle contraction, leading to the characteristic symptoms of BD.In some cases of BD, no mutations in ATP2A1 have been observed. Disease transmission in cases of non-ATP2A1 BD have been characterized as autosomal dominant pattern of inheritance.
