What is carpal tunnel syndrome? Carpus is a word derived from the Greek word karpos‚ which means "wrist." The wrist is surrounded by a band of fibrous tissue that normally functions as a support for the joint. The tight space between this fibrous band and the wrist bone is called the carpal tunnel. The median nerve passes through the carpal tunnel to receive sensations from the thumb‚ index‚ and middle fingers of the hand. Any condition that causes swelling or a change in position of the tissue

some motor neurons in the spinal cord have axons that exceed 1 m in length‚ connecting the spine to the lower limb muscles. These axons transmit signals to the target muscle in the form of electric impulses called action potentials. However‚ the axons alone are not enough to produce rapid conduction of the electric current necessary for this signal to be sent. Glial cells are the key element for supporting the messages neurons send and receive all over the body. Much like the insulation around the

Magnesium‚ an abundant mineral in the body‚ is naturally present in many foods‚ added to other food products‚ available as a dietary supplement‚ and present in some medicines (such as antacids and laxatives). Magnesium is a cofactor in more than 300 enzyme systems that regulate diverse biochemical reactions in the body‚ including protein synthesis‚ muscle and nerve function‚ blood glucose control‚ and blood pressure regulation [1-3]. Magnesium is required for energy production‚ oxidative phosphorylation

the core temperature within a narrow range. During exercise in the heat‚ the heat loss mechanisms compete with the active muscles for more of the limited blood volume. Thus‚ neither area is adequately supplied under extreme conditions. Heat conduction is when the heat transferred from one material to another through direct molecular contact. Heat generated deep in the body can be conducted through adjacent tissue until it reaches your body’s surface. It can be conducted to clothing or to the

1. Describe and give examples of the various ways that heat can be transported in the atmosphere. In the atmosphere‚ heat is transferred by conduction‚ convection‚ and radiation. Conduction is the transfer of heat from molecule to molecule. An example of conduction would be burning your hand after touching a hot stove. Convection is the transfer of heat by the mass movement of fluid. A good example of convection is actually a microwave oven. Radiation is the heat transfer that travels in the form

San Francisco‚ California has cooler summers but warmer winter as opposed to Saint Louis‚ Missouri. There are many things that affect this situation such as California being closer to water‚ Air Temperature/water temperature is cooler‚ and the water temperature is 27°. First‚ California is closer to the water. This results in cooler summers and warmer winters because there is a smaller temperature change in water rather than soil when it is exposed to heat. Saint Louis isn’t near any large body of

measuring the temperature distribution for steady state conduction of energy through a specific efficient unit. • Understand the Fourier Law of heat conduction and the usage of its equation in determining the rate of heat flow via solid materials. II. Theory : The Fourier Rate Equation: When a plane section of ∆x and a constant area A maintains a temperature difference ∆T‚ then the heat transfer rate per unit time by conduction through the wall is found to be: Q α A

securely. Pour HCL into the burette with a funnel until it reaches the 0.0cm3 mark. e)The risk of using plastic cup in this experiment is that the plastic material is too thin which will cause the outside surface of the plastic cup to be hot due to conduction. Furthermore‚ plastic is not a good insulator as compared to polystyrene cup and this will cause heat loss which will affect the reading of the experiment ii)NaOH is a strong alkaline solution that can cause severe chemical burns if it is in contact
