Muscle Strain Overview- Muscle strain‚ also termed as muscle tear and muscle pull is related to the muscle damage and its attached tendons. It occurs when you give excessive pressure on muscles during performing daily life activities like during sports or heavy weight lifting.it can be in the form of tearing of the fibres of your muscles and attaching tendons. In addition to this it also affects small blood vessels which leads to bleeding‚ bruising and pain. Causes- A severe muscle strain occurs

it requires muscles to adduct and abduct as well as give it strength to bite on hard food such as tooth-crackers. Muscles of mastication are known to be the most crucial muscles in the head aside from the muscles that are required to show facial expressions. The four muscles of mastication include: • Masseter muscle • Temporalis muscle • Medial pterygoid muscle • Lateral pterygoid muscle Each of which has a

Muscle contractions are the way that humans are able to move within the enviornment that surrounds them. To be able to understand the complexity of movement‚ there needs to be an understanding of the gross and micro-anatomy muscle contraction‚ and an understanding of the physiology of muscle contraction. This paper will provide an explaination of both the anatomy and physiology of muscle contraction. Anatomy of Muscle Contraction There are three types of muslces within the human body: skeletal

forces generated in muscles through the application of the laws of motion from Newtonian mechanics. The movement is actively controlled by the motor commands generated in the central nervous system and sent to the musculoskeletal system through the descending tracts. These motor commands can be estimated with the electrical activities in the muscle tissue‚ which are recorded using electromyography (EMG) techniques. The activity of muscles as a function of time‚ also known as muscle activations provides

extension is the movement of straightening the leg at the knee joint. The major muscle involved in knee extension is the Quadriceps femoris‚ which is a group of four muscles. These four separate muscles of the Quadriceps femoris are the Vastus lateralis‚ Vastus medialis‚ Vastus intermedius‚ and Rectus femoris. These muscles‚ along with synergists‚ work together to perform knee extension for a vertical jump. Each of the muscles of the Quadriceps femoris have different origins‚ however they all share a

Abstract The purpose of this experiment was to use the muscle tension and the electrical activity in the dominant and non-dominant forearm muscle‚ the flexor digitorum superficialis‚ to analyze the determinants of muscle tension and fatigue‚ and the reasons as to why differences may occur between the dominant and non-dominant arm. The generation of tension in a muscle is determined by the major type of motor unit being recruited‚ as well as the rate in which action potentials are being fired. A subject

The pelvic floor consists of layers of muscles “stretching like a hammock from the pubic bone in the front‚ to the base of the spine” (O’Connell‚ Bennett & Jarvis‚ 2004). There are three openings that pass through the pelvic floor; the urethra from the bladder‚ the vagina from the uterus and the anus from the bowel (The Royal Women’s Hospital Fact Sheet‚ 2010). The pelvic floor muscles work to support the bladder‚ uterus and bowel (Hendy‚ 2006; The Royal Women’s
