What is randomly coiled protein fibers that recoil after being stretch?
Elastic fibers made of the protein elastin has a coiled structure which allows it to stretch and recoil. Fibers can stretch up to 150 percent of their relaxed state length without breaking.
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.
The all-or-none law applies to skeletal muscle function at what level?
The all-or-none law applies to individual muscle fibers within a skeletal muscle. This means that when a muscle fiber is stimulated by a motor neuron, it will either contract maximally or not at all, depending on whether the stimulus reaches the threshold for activation.
What is the role of the spindle fibers?
Spindle-shaped muscle fibers are skeletal muscles that produce external mobility to the body.
Does glycerinated skeletal muscle fibers need calcium in order to contract?
Yes, glycerinated skeletal muscle fibers still require calcium in order to contract. The glycerination process maintains the basic structure of the muscle fibers but removes cellular components, allowing for the fibers to contract in response to calcium in a controlled laboratory setting.
What changes are thought to occur in the skeletal muscle to allow treppe to be observed?
This is known as wave summation. It is when the fibers of the muscles become stimulated before having a chance to relax completely.
What is a group of skeletal muscle fibers?
A skeletal muscle
Is skeletal muscle made of muscle fibers?
Basically, yes. All muscle (skeletal, cardiac and smooth) are made of muscle fibers.
What ensures that one action potential in the neuron yields only one action potential in the skeletal muscle fibers of the stimulated motor unit and therefore only one contraction per fiber?
sarcoplasmic reticulum
What is randomly coiled protein fibers that recoil after being stretch?
Elastic fibers made of the protein elastin has a coiled structure which allows it to stretch and recoil. Fibers can stretch up to 150 percent of their relaxed state length without breaking.
What fibers stretch across a cell during mitosisis?
spindle fibers
Skeletal muscle fibers are encased in?
Endomysium
What are skeletal muscle fibers enclosed in?
endomysium
True or false smooth muscle fibers are located in small skeletal muscles?
smooth muscle fibers are located in small skeletal muscle
The delicate connective tisssue that surrounds the skeletal muscle fibers and ties adjacent muscle fibers together is the?
The delicate connective tissue that surrounds the skeletal muscle fibers and ties adjacent muscle fibers together is the endomysium.
Do Skeletal muscle fibers tend to be shorter than smooth muscle fibers?
False
What types of fibers are there?
You have three types of muscle fibers. 1) Skeletal muscle fibers. 2) Cardiac muscle fibers. 3) Smooth muscle fibers.
