How fast does a muscle contract?
The fastest a muscle fiber can contract is 0.01 seconds or less. However, this is not necessarily the speed that the actual muscle contracts at. For example, the human eyelid can only blink in 0.15 seconds.
What are all muscle cells called?
A single muscle cell is called a muscle fiber.
How are ATp levels affected by muscle fatigue?
There has been no universal mechanism found to explain skeletal muscle fatigue. With the onset of intense exercise, muscle force has been shown to fall, which is often illustrated as a sign of fatigue. As ATP supplies the immediate energy to the muscle cell, the relationship between ATP and fatigue has been a topic of interest among researchers. During muscle contraction the majority of ATP is used for cross bridge cycling, ion pumps and transporters, and chemical signalling cascades. A fall in [ATP] would result in the development of rigor and goes against the viability of the cell. It is proposed that whole muscle [ATP] does not fall with repeated contraction, though there may be differences in [ATP] between fiber types with fatigue. Rather, fatigue is a protective mechanism by the muscle to preserve [ATP] accomplished by down regulating cellular processes that use ATP for energy
What are fatigue resistant fibers?
slow fiber
What is the Smaller fiber in a muscle fiber?
Myofibril
Exercise can do what?
make more muscle fiber
What is the term for a Smaller fiber in a muscle fiber?
The smaller fiber in a muscle fiber is called a myofibril. A band of tissue that connects bone to bone is called a ligament.
What is a single muscle called?
a muscle fiber
What is the basic unit of muscle?
muscle fiber
What is the part of the muscle fiber that allows the fiber to contract?
The sacromere with the proteins actin and myosin allow the muscle cell (fiber) to contract.
What are the structures within the muscle fiber that shorten to cause skeletal muscle fiber contraction?
Myofibrils
What type yogurt grows mold the fastest?
the fastest is fiber yogurt.
