Molecules In Cold Muscle

Pages: 2

Molecules in cold objects move slower than that of warm objects (Burdge, 2014). It should then follow that a cold muscle will have less strength than a warm muscle. In order to better understand this, it is necessary to understand the physiological process. A muscle is stimulated by an action potential (Kincaid, 1999). An action potential is affected by temperature because molecules are affected by temperature (Buzantu, 2009). The contraction of a muscle occurs when calcium ions allow myosin to bind with actin in the sarcomere (Fox, 2009). Since calcium ions are atoms they too suffer from the effects of temperature. The strength of a muscle contraction is based on two things, the number of motor units recruited or temporal summation (Taylor,

composition and mass) 4) a combination of evaporation (from the moisture in the lungs) and convection (the displacement of warm air in the lungs, by cold air from the surrounding environment coming in). Moisture is lost through exchanging the air in the lungs with drier air from outside the body. This occurs during breathing. 5) the movement of molecules across the body results in heat being taken off and away from the body because of the convective currents passing by. For example, wind cools you…

Proprioception Essay

Q1 Proprioception is the sense that gives us our awareness of the relative positions of the different parts of our bodies. The system has sensors within joints, muscles and skin which relays information to the brain about joint angles and skin and muscle stretch. Its role is to act as the start point of any sequence of movement as without information about where we are now we could not format the instructions for moving to where we want to move to. Rather like asking a GPS system to guide you…
