We have three types of muscles in our bodies‚ skeletal‚ smooth and cardiac. Each type of muscle performs different functions in our bodies. Some of the characteristics of our muscles are that they respond to stimuli‚ they are able to shorten in length‚ they stretch when they are pulled and they tend to return to their original shape after contracting or extending them. Muscle contractions occur when our nervous system sends a signal via the neuromuscular junctions the signal arrives at the end bulb

ACTIVITY 1: THE RESTING MEMBRANE POTENTIAL 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out the neuron through the K+ leak channels? When the diffusion is greater on one side‚ the other side will slow down. 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative value. How well did the results compare with your predictions? There are two potassium’s for every sodium so the increase of potassium will make it more

naked eye. What is the skeletal system? The skeletal system is a very important part of the human body this consists of 206 bones‚ which together with different structures make the joints of the system. Within the skeletal system the structures present are the cartilage‚ bone tissues‚ fibrous connective tissues which form the ligaments of the bones Scanlon and Sanders‚ pp.122‚ 2014). The skeletal system consists of two main organs these are the ligaments and bones‚ the skeletal system functions by

Cardio Pulmonary Practical The main aim of the practical was to assess‚ what affects did light exercise have on the systolic and diastolic blood pressure‚ heart and respiration rate‚ tidal volume‚ minute volume and percentage of gas. The readings were taken before exercise‚ during exercise and after exercise. Blood pressure is defined as the amount of pressure exerted on the vessels walls‚ during blood flow. Blood pressure can be measured using a sphygmomanometer. The upper value indicates the
