Your 80 year-old great aunt‚ Persis‚ was placing a canning jar on the top shelf of her pantry when she stepped awkwardly off the stool and twisted her leg at the hip. She felt a sharp pain in her hip and‚ after collapsing to the floor‚ found she could no longer stand. She was taken to the emergency room where an X ray showed that the neck of her femur was fractured. More detailed X ray images revealed reduced bone mass in the head and neck regions of the injured femur‚ in the ends of other long

Unit 9 Assignment 2 Chun Ho Yeung What is homeostasis? Homeostasis refers to maintaining the internal environment such as temperature‚ pH‚ blood pressure‚ blood sugar levels and fluid balance within a narrow range to ensure that cells can perform their best functions in an optimal environment‚ and to maintaining a constant relationship with the external environment. Although the external environment is changing‚ the human body can still maintain a stable internal environment and maintain the dynamic

Outline the differences between the excitation-contraction coupling mechanism between skeletal and cardiac muscles. Excitation-contraction coupling is the combination of the electrical and mechanical events in the muscle fibres and is related by the release of calcium from the sarcoplasmic reticulum. (Silverthorn‚ 2007) In the skeletal muscle‚ action potential in the nerves is generated when the somatic motor neurons releases the neurotransmitter acetylcholine (ACh)‚ at the neuromuscular junction

"Explain the concept of homeostasis with reference to the control of heart rate‚ breathing rate‚ body temperature and blood glucose levels" P5 Homeostasis is where the body keeps a constant internal environment. This involves all the metabolic processes taking place In the body as well as the blood‚ tissue fluid and all the contents in the body ’s cells. There are a range of variables from heart rate to the blood glucose levels that the body will take into account. Negative feedback will occur
