What else can I help you with?
Does muscle fibers brake down during exercise?
Yes. Strenuous exercise can kill the muscle fibers. Such muscle fibers are replaced by fibrous tissue.
Muscle fibers contract and relax in response to what?
nerve impulses
How is the all-or-none response related to the strength of a muscle contraction?
The all-or-none response means that a muscle fiber contracts fully or not at all in response to a stimulus. The strength of a muscle contraction is determined by the number of muscle fibers that are recruited to contract, rather than the degree of contraction of individual muscle fibers. Therefore, the all-or-none response influences the overall strength of a muscle contraction by determining how many muscle fibers are activated.
The enlargement of muscle fibers as a result of physical exercise is called?
Hypertrophy
A thickening of existing muscle fibers is called?
Muscle hypertrophy is the thickening or increase in the size of existing muscle fibers. This process occurs in response to resistance training or overload, leading to an increase in muscle strength and size.
How does repeated exercise affect the amount of work that muscles can do?
When you exercise, you tear muscle fibers. Over time, these muscle fibers become thicker to prevent tearing. This is why your biceps bulge - it's actually just strands of muscle that have been torn through exercise and then grown back. Thicker muscles = more strength.
What is a satellite cell?
A satellite cell is a type of stem cell found in skeletal muscle tissue. These cells play a key role in muscle repair and growth by proliferating and differentiating into new muscle fibers in response to injury or exercise.
What make up nervous muscle tissue?
Muscle tissue made up of elongated muscle fibers, fibers that contract in response to stimuli. Nervous Tissue is made up of neurons and neurological cells.

What type of exercise do we use Fast twitch muscle fibers?
Strength and power exercise like weight lifting requires the explosive release of energy yielded by fast-twitch muscle fibers. Slow-twitch muscles are involved in endurance activity.
What type of muscle fibers are there?
You have three types of muscle fibers. 1) Skeletal muscle fibers. 2) Cardiac muscle fibers. 3) Smooth muscle fibers.
