Definition The median nerve‚ which controls movement and feeling in the palm-side of the hand‚ runs from the forearm to the hand through the carpal tunnel in the wrist. The bottom and sides of this tunnel are formed by bones‚ and the top of the tunnel is covered by strong band of connective tissue called a ligament. Repetetive movement‚ or certain conditions such as pregnancy and arthritis‚ can cause swelling within the carpal tunnel. The swelling puts pressure on the median nerve and can cause numbness

loses body heat easily. There are four sources of heat loss in newborns such as evaporation‚ conduction‚ convection‚ and radiation. Evaporation is when fluid evaporates from the skin due to sensible (sweating) or insensible (skin and breathing) losses. There are also other factors that contribute to evaporation and newborns‚ vapor pressure and air velocity is the main cause of newborn’s heat loss. Conduction is when the newborns are placed on a cool surface. The transfer of heat between two objects

A sound wave has characteristics just like any other type of wave‚ including amplitude‚ velocity‚ wavelength and frequency. The amplitude of a sound wave is its loudness. Since sound is a compression wave‚ its loudness or amplitude would correspond to how much the wave is compressed. The velocity of a sound wave is or close too 344 meters/second‚ 1130 feet/sec. or
