What is the contractile organelle of skeletal muscle fibers is?
myofibrils
Does increased muscle density mean more myofibrils per muscle fiber?
Yes, increased muscle density often correlates with having more myofibrils per muscle fiber. Myofibrils are the contractile units within muscle fibers responsible for generating force and producing movement. When muscle density is increased, it usually indicates that there is a higher concentration of muscle fibers and myofibrils within a specific area, leading to greater strength and muscle function.
Individual muscle cells are called?
muscle fibre
How can exercise change muscle strength?
Muscle strength depends on the thickness of the fibers and the number of fibers contract at one time. And in order to compensate for the added work load,myofibrils are added in in order to increase the thickness of the fibers (more myofibrils,more thickness), hence a stronger muscle.
What are the muscle structures from largest to smallest?
The organization of a skeletal muscle from smallest to largest is as follows: myofilaments > myofibrils > muscle fiber > fascicle > muscle
What are muscle fibers that contains many bundles of cylindrical structure called?
Muscle fibers that contain many bundles of cylindrical structures are called myofibrils. Myofibrils are the contractile units within muscle fibers that are composed of repeating units called sarcomeres. Sarcomeres are responsible for muscle contractions by sliding past each other during the contraction process.
What type of skeletal muscle fibers are largest in diameter and contain most myofibrils?
Fast Glycolytic
What are Long threadlike structures found in muscle fibers?
Myofibrils are thread like structures found in muscle fiber composed of bundles of myofilaments.
What happens to a muscle in the body when it gets longer?
You get stronger. The individual muscle fibers become thicker with more myofibrils inside them. The number of muscle cells stays the same, contrary to popular belief that you grow more muscle fibers, this is not true.
What is the name of the repeating pattern of units of a muscle cell?
I do believe you are asking about a sarcomere, units of repeating bands that make up the fibers (myofibrils) of a striated muscle.
How many sarcomere in a muscle cell?
There are unknown amounts of fibers (fibre) in muscles
What are the longitudinal bundles in the cytoplasm of a skeletal?
Myofibril If you're looking for the answer for Medical Mayham it's myofibril.
