Ch 10 The unit of muscle structure that is composed of bundles of myofibrils‚ enclosed within a sarcolemma‚ and surrounded by a connective tissue covering called endomysium is a muscle fiber. The plasma membrane of a skeletal muscle fiber is called the Sarcolemma In a skeletal muscle fiber‚ Ca2+ is stored within the sarcoplasmic reticulum The bundle of dense regular connective tissue that attaches a skeletal muscle to bone is called a(n) tendon. In excitation-contraction coupling

Muscles are a Band or bundles of tissue in either the human body ‚ or animal body that allow contraction for movement. There are many muscles in the body. It is stated that there are over 650 muscles in the body ‚ and is said that there are possibilities of up to 840. Your whole body is a muscle. You have Muscles in your head‚ arms‚ legs‚ just about anywhere you can think of and as we progress in life and become of age our muscles may grow and get stronger ‚ or may deteriorate. We can also come across

system is to make the body move‚ a signal travels along neurons nerve cells from the brain to the spinal cord. There‚ "lower motor neurons" pass the message on to the muscles. The end of every lower motor neuron releases a chemical‚ which is received by receptors in the muscle tissue. Once enough of the chemical has been received‚ the muscle is able to move. Sometimes this process malfunctions and a person develops a neuromuscular disorder. Symptoms include muscular weakness‚ spasms‚

extensibility‚ and elasticity. State why each of these properties is necessary for muscle function. a. Responsiveness- is a property of all living cells- Muscle and nerve cells have developed this property to the highest degree. When stimulated by chemical signals‚ stretch‚ and other stimuli‚ muscle cells respond with electrical changes across the plasma membrane. b. Conductivity- Stimulation of a muscle cell produces more than a local effect- The local electrical change triggers a wave

Building muscles may be the purpose of many people and for doing so‚ they usually start with an intense weight training. What most of them don’t know‚ is that for building muscles‚ the balance is only 20% weight training and 80% a proper diet. Therefore‚ for those who are interested in building muscles‚ these article will provide information on how they have to introduce in their daily routine a strict diet that includes proteins‚ carbohydrates‚ or healthy fats. Proteins Muscles need proteins

Weights programme – The programme designed has been designed to target all muscle groups effectively using a wide range of exercises. Exercises for the pectorals such as the bench press‚ exercises for the latissimus dorsi such as the lat pulldown‚ etc. I have created a programme consisting of 6 exercises. The exercises are bench press‚ lat pulldown‚ leg press‚ dumbbell shoulder press and bicep curl and tricep pushdown. The first exercise is bench press. This exercise can either be performed using
