1. The number of muscle fibers that are innervated by a motor neuron is dependent on what muscle it is. Fine motor movements, such as typing, would need only a few muscle fibers. This means that the thumb has only a few fibers, but the thigh, back, and biceps have many. These need a lot more force to be exerted, which is why they need more muscle fibers. Using your thumb and bladder does not require many muscle fibers. 2. Alpha motor neurons innervate extrafusal muscles but gamma motor neurons…

Muscle cramps Toggle: English / Spanish Definition Muscle pain are when a muscular gets restricted (contracts) without you trying to stressed up it, and it does not relax. Pains may consist of all or part of one or more muscles. The most usually involved muscles are: Coming back of the reduced leg/calf Coming back of the higher leg (hamstrings) Front side of the higher leg (quadriceps) Cramps in you, arms, arms, abdomen, and along the rib cage are also very common. Muscle pain…

program entails exercises that are resistance based to build muscle strength overall. I have also prescribed a series of stretches in order to improve my client’s flexibility which is another goal of her (improve in sit and reach test).

You absolutely need this muscles to lift things up. The stronger you are, the more weight you can lift. When you are…

The objectives were to record the force produced by the clench muscle experiment listening to techno music and no music. The observations were to see if more motor unit recruitment came with techno music in the individual’s dominant hand. There were three participants used that were all females in the same range of age of 22-25. One of the individuals was a left hand dominant and the other two were a right hand dominant. A hand dynamometer was used for the BSL PRO3.7.5 software on a…

The one repetition maximum test is a common method of measuring isotonic muscle strength. It is a rough measurement of the heaviest weight a participant can perform a clean lift. It is recommended that you should only warm up before as you will not want to risk injury but by doing too much your muscles would have already begun to fatigue. Then after a rest of at least several minutes, increase the weight and try again. The athletes chooses subsequent weights until they can only repeat one full…

Brachialis muscle was seen uniformly to be consisting of 2 heads, superficial and deep. The superficial head forming the main bulk of the muscle originated from the anteromedial and anterolateral surface of the middle third of humerus ,embracing the deltoid insertion. In addition it also had attachement to the adjoining part of the lateral intermuscular septum. Its fibers ran vertically and terminated in a thick tendon to be inserted onto the ulnar tuberosity. Fibers of…

Muscles (Grip strength) In this week’s lab, we was doing an experiment on forearm, and its muscle fiber with nerves. The forearm is a part that between the primates’ elbow and wrist. Forearms contain connective tissue, nerve tissue and muscle tissue. In which, connective tissue is just radius and ulnar bones. However, there are a great deal of muscles and nerves in the forearm. When a nerve impulse transmission to synaptosomes induced depolarization, allows calcium ions to enter the cell…
