What else can I help you with?
What happens to muscles without normal stimulation?
Atrophy
Are nerves needed for muscles to contract?
Yes, without the nerves the muscles would be rendered useless. The muscles MUST have stimulation from somehwere in order to contract.
Why do you get a twitch?
You can get a twitch from stimulation or damage to the muscles.
Skeletal muscles need nerve stimulation for contraction to occur?
Yes, nerve stimulation is necessary for skeletal muscles to contract. This stimulation causes an action potential to travel down the motor neuron, leading to the release of acetylcholine at the neuromuscular junction, which triggers muscle contraction by causing calcium release in the muscle fiber. Without this nerve input, skeletal muscles would not be able to contract voluntarily.
Why does electricity contract your muscles?
When electricity passes through your muscles, it disrupts the normal flow of signals from your brain to your muscles, causing them to contract involuntarily. This phenomenon is known as electrical muscle stimulation and is commonly used in physical therapy and fitness training to help strengthen muscles and improve circulation.
Does skeletal muscle need stimulation to contract?
Yes! Although we have total control over these muscles, they still need stimulation to contract. The difference with muscles that we don't control is that we decide if we want to make this stimulation.
What is a disease of the muscles which results from some problem with stimulation of muscles by acetylcholine?
This disease is known as myesthenia gravis.
What muscle fibers pull in different directions depending on stimulation?
Skeletal muscles
What do muscles do list two different functions of muscles?
Some muscles (skeletal muscles) will not contract unless stimulated by neurons; other muscles (smooth & cardiac) will contract without nervous stimulation but their contraction can be influenced by the nervous system. Thus, the nervous and muscle systems are closely interconnected.
What is vasomotor tone?
Constant level of nervous stimulation to the muscles in the blood vessel walls. This gives the muscles a resting level of contraction.
What element plays an essential role in the response of nerves to stimulation and in contraction of muscles?
potassium
What types of muscles stimulator are available on the market?
The most common type of muscle simulator that is available on the buyer's market are electrical muscle stimulation devices. These types of muscle stimulation devices use an non-harmful electrical current to stimulate weak muscles.
