Background Research About Muscles
Ideas for data
The longest muscle in the body is the sartorial which is a long thin muscle that runs down the length of the upper thigh, crossing the leg down to the inside of the knee.
A Muscle Contraction Is Triggered When an Action Potential Travels Along the Nerves to the Muscles. Muscle contraction begins when the nervous system generates a signal. The signal, an impulse called an action potential, travels through a type of nerve cell called a motor neuron.
Sensory nerves relay information from the skin and muscles back to the spinal cord and brain.
There are three types of muscle contraction: concentric, isometric, and eccentric.
Motor nerves control the movements and actions by passing information from your brain and spinal cord to the muscles.
Differences between 3 types of muscles
The largest muscle in the body is the gluteus Maximus which is located in the buttocks and is regarded as the strongest muscles in the body. It is responsible for the movement of the hip and thigh.
Muscles are all made of the same material, a type of elastic tissue. The body contains more than 600 muscles and have thousands of special cells called muscle fibres that make up each muscle.
The nervous system provides the link between thoughts and actions by relaying messages. Nerves and muscles work together as the neuromuscular system, which makes the body move accordingly, voluntarily and involuntarily.
cardiac muscles connects at branching, irregular angles called intercalated dice. they are located in the walls of the heart. Involuntary
skeletal muscles are arranged in regular, parallel bundles.they are long, thin, multinucleate fibres that are crossed with regular pattern of ren and white lines. giving the muscle a distinctive appearance. they are bound together by connective tissue and communicate with nerves and blood vessels. They occur in muscles which are attached to the skeleton Voluntary
smooth muscle sustains longer or even near-permanent contractions. They interconnect with cells to form layers. It stimulates the contractility of the digestive, urinary, reproductive systems, blood vessels ad airways. They are controlled by the Autonomous Nervous System. Involuntary
Both are striated muscles which contracts and relaxes in short, intense bursts. They are composed of muscle fibers, made up of thick and thin filaments.
The somatic nervous system consists of nerves that connect the brain and spinal cord with muscles controlled by conscious effort (involuntary and voluntary) and with sensory receptors in the skin.
skeletal muscles can regenerate completely and spontaneously in response to minor injuries such as strain.
The typical reaction time for a human is about 250 milliseconds which means that it takes about a quarter of a second after to physically react to it.
isotonic contraction involves muscular contraction against resistance in which the length of the muscle changes
A concentric contraction is a type of muscle activation that causes tension on your muscle as it shortens. As your muscle shortens, it generates enough force to move an object
Eccentric contraction occurs when the total length of the muscle increases as tension is produced
how far the muscle can contract
Measure the wave lengths of the electrical currents that is going through to the nerves
flexibility
The effect of age on muscle strength
The TENS machine (transcutaneous electrical nerve stimulation) is a small portable device that is normally used as a pain killing medication
there are 630 muscles in the body
how fast can the muscle contract
might cause injuries
depends what's available at the ASMS
might cause injuries
