What are the structures within the muscle fiber that shorten to cause skeletal muscle fiber contraction?
Myofibrils
What are the Skeletal muscle cells that function in calcium storage?
in the sarcoplasmic reticulum of a muscle fiber/cell.
Why are skeletal muscle cells multinucleated?
The number of cells depends on how large the muscle is; muscles consist of fiber bundles, which are made up of myofibrils. A sarcomere is one of the segments that the myofibril is divided into. In each fiber bundle there are multinucleate cells, which can extend the length of the skeletal muscle. So, the number of cells in a skeletal muscle depends on the size of the muscle. for example, the number of cells in one of our triceps larger than one of the small muscles in a finger.
What enzyme has to be present for acetylcholine to be broken down so that the muscle fiber can relax?
Acetycholine esterase. It breaks down Ach in the skeletal muscle endplate.
What is the function of End Plates?
A motor endplate is a large special synaptic contact between motor axons and each skeletal muscle fiber. Each muscle fiber forms one endplate. Its function is to transmit impulses from nerves to muscles.
What is the multinucleate muscle fiber?
Skeletal
What are the structures within the muscle fiber that shorten to cause skeletal muscle fiber contraction?
Myofibrils
How relaxation in a skeletal muscle fiber occurs?
Relaxation of a skeletal muscle usually involves the Golgi tendon proprioceptors.
Most skeletal muscles contain?
muscle fiber
A specialized cell found in a skeletal muscle is called a muscle fiber?
true
The cytoplasm of a skeletal muscle fiber is called the?
Sarcoplasm
What are the repeating segments seen in skeletal muscle fiber?
sarcomeres
What is the correct sequencing of the microstructure of skeletal muscle?
muscle fiber, myofibril, myofilaments, sarcomere
How are the Neuron and skeletal muscle fiber connected?
they are connected with the rope in the body
How is a skeletal muscle fiber stimulated by a motor neuron?
motor unitUnit
What is the name of small contractile elements of skeletal muscle fiber?
sarcomere
What type of sensory receptors are made up of very small skeletal muscle fiber?
muscle spindles
