Skeletal muscle fibers are composed of thousands of fibers, each with a covering of loose connective tissue-endomysium. The fibers are organized in parallel bundles called fascicles. Each fascicle is surrounded by a perimysium sheath; the presence of collagen bundles suggests dense connective tissue. Multiple fascicles are encased in a dense connective tissue-epimysium, which covers the entire muscle organ. Blood vessels and nerve fibers penetrate to the endomysium to supply the muscle fibers.

Describe the 'all or nothing' principle of muscle fiber recruitment?
HORRIBLY CONDENSED. An electrical event of sufficient strength from the end of a nerve to pass into a muscle fiber(s) (end plate) resulting fiber(s) tension. The more electrical events 'spikes" per second (rate coding) to a point the greater, to a point, the tension(s).
What are the three methods of fiber identification?
The three methods of fiber identification are microscopic view,burning test,chemical test.
Each muscle fiber is also called a?
muscle cell
What cellular organelle in muscle fiber corresponds to the endoplasmic reticulum?
Sarcoplasmic reticulum is the cellular organelle in muscle fiber that corresponds to the endoplasmic reticulum.
Does increased muscle density mean more myofibrils per muscle fiber?
Yes, it means that you will gain more myofibrils per muscle fiber. A muscle fiber is a muscle cell, and everybody has about the same number. When you train your muscles, they will develop more myofibrils inside the muscle cells. So you cannot change the number of muscle fibers, or cells, but you can change the number of fibers, or myofibrils, inside them. The end result is more muscle density, not more muscle cells.
Describe the components of the neuromuscular junction?
Axon,motor end plate,synaptic cleft and muscle fiber.
Why muscle cell called muscle fibre?
Muscle cells are called muscle fibers because of their long, slender shape that resembles a fiber. The structure of muscle cells allows them to contract and generate force, which is essential for muscle function. The term "fiber" is used to describe the long, cylindrical shape of these cells that run parallel to each other in muscle tissue.
What are all muscle cells called?
A single muscle cell is called a muscle fiber.
What is the Smaller fiber in a muscle fiber?
Myofibril
Exercise can do what?
make more muscle fiber
What fiber a swim suit is made of?
microscopic metal wires
What is a single muscle called?
a muscle fiber
What is the basic unit of muscle?
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 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
Does most muscle contain a fibers of the same type?
Mostly muscle cells
