function of hypothalamic structures‚ and emotional feeling results from stimulations of the dorsal thalamus. The physiological changes and subjective feeling of an emotion in response to a stimulus are separate and independent; arousal does not have to occur before the emotion (Adcock‚ 1976).

Aerobic respiration requires the presence of oxygen and releases high amounts of energy. Glycolysis is anaerobic; as it occurs whether or not oxygen is present

Patella dislocation most commonly occurs when the patella‚ a large sesamoid bone‚ shifts laterally out of the femoral trochlear (Mackay et al. 2014). This may happen due to a direct trauma‚ such as unusual shear force‚ which may occur whilst playing sport or exercise. However‚ it may also occur indirectly due to biomechanical variance‚ such as an increased quadriceps angle‚ trochlear dysplasia or general patella instability (Cheng et al. 2014). The main mechanism involved in a dislocation is a sudden

which occur naturally are known as natural disasters. There are infinite natural disasters. Some of them are landslides‚ floods and volcanic eruptions. By taking the example of planets orbiting around the sun‚ the question rises that how do these devastating disasters occur? Floods occur in those areas which are closer to seas. Due to heavy rain‚ the sea water increases and spills out over the area with speed and destroying everything. Flash floods are another example of floods which occur suddenly
