Muscle

Muscles work in pairs. one muscle contracts and pulls on the bones to which they are attached, in other word, Tendons which are fibrous connective tissue, muscle are attached to bones by tendons. The muscles contract to allow movement, while the skeletal gives the muscles support. The muscles and bones move together, basically with the muscles contracting the bones. The bone can not move back to its original state until another muscle pulls on it. Muscles work together to produce movement by…

1. Skeletal muscle used ATP to contract. Then, ATP is broken down into ADP and P, which release energy. 2. A) The sarcoplasmic reticulum is the organelle that stores calcium in muscles cells. B) In order for calcium to be released from this organelle some events must occur. First, an action potential needs to reach the synaptic terminal. Then acetylcholine needs to be released into the sarcoplasm. After that, ACH molecules will land on receptors that are on the motor end plate. Then, an action…

Electronic muscle stimulators, also known as EMS devices, are machines that aid people in toning their muscles. These types of machines can help an individual keep their body toned, in shape and according to some, enable them to lose weight. They are also used by physical therapists and health care professionals for the relief of minor joint pains, muscle aches and stress. For individuals who suffer from partial to full paralysis or have hard time moving, electronic muscle stimulation via these…

What is meant by “agonist and antagonist muscle pairs”? Give an example What is meant by agonist in muscle pairs is that it does the majority of the workload in an exercise and is considered the prime mover (primarily responsible for movement). The antagonist in respect to the agonist counteracts. The antagonist helps allow the agonist to perform a task. An example could be the biceps brachii contracts when doing elbow flexion. While the antagonist would be the triceps brachii relaxing during…

Adductor Muscle Strain An adductor muscle strain, also called a groin strain or pull, is an injury to the muscles or tendon on the upper inner part of the thigh. These muscles are called the adductor muscles or groin muscles. They are responsible for moving the leg across the body. A muscle strain occurs when a muscle is overstretched and some muscle fibers are torn. An adductor muscle strain can range from mild to severe depending on how many muscle fibers are affected and whether the muscle…

Bronchial Smooth Muscle Contraction and Relaxation Abstract Smooth muscles in human airways have multiple pathways for excitation and contraction. Both electrical and chemical signals regulate bronchial smooth muscle excitation. Bronchial smooth muscle is innervated by parasympathetic cholinergic nerves for contractile forces and by parasympathetic noncholinergic nerves for relaxant forces. Specifically, cholinergic nerves that secrete acetylcholine to muscarinic receptors cause smooth muscle…

rotate the pelvis anteriorly[17]. 2.2.2 Psoas This muscle is only muscle group in human body with direct attachment to the spine, the pelvis and the femur. Therefore it has potential to influence, and influenced by movement at both of the spine and hip joints[18]. 2.2.3 Gluteal maximus muscle: superficial group The gluteus maximus muscle is the one of the largest muscle in the gluteal region and it covers most of the other gluteal muscles. It is quadrangular in shape and has a broad…

athlete's, legs are also very important. One important muscle group of the leg includes the quadriceps muscles, otherwise known as the quadriceps femoris. The quadriceps are made out of four other different muscles, that all work towards a specific function for the body. Although it might not be one of the most important muscles, the quadriceps muscles are a very important leg muscle that has a great impact on our lives. The quadricep femoris muscles cover most of the femur and is made up of…

INTRODUCTION The proteins actin and myosin is the caused of excitement of skeletal muscle. It can be made chemical, electrical and mechanic. When the muscles are use many times to the maximum force, the muscle will decline. That decline is called muscle fatigue. 1 L-Carnitine is a compound that makes the increment of the muscle performace. L-Carnitine is found in the entire cell on the body, its function is to change fats to energy and transport the fatty acids to the mitochondria. L-Carnitine…

Duchenne Muscle Dystrophy Introduction: “Muscular Dystrophy is a group of muscle diseases that weaken the musculoskeletal system. Muscle Dystrophies are characterized by muscle weakness, defects in muscle proteins and the death of muscle cells and tissue. Duchenne Muscular Dystrophy is one of many types found and it passed down through the X chromosome. DMD is one of the most common muscle diseases found in early childhood. 1 in 3500 boys are born with DMD however very rarely affects girls…
