What else can I help you with?
A specialized cell found in a skeletal muscle is called a muscle fiber?
true
What is the multinucleate muscle fiber?
Skeletal
What are the structures within the muscle fiber that shorten to cause skeletal muscle fiber contraction?
The structures within the muscle fiber that shorten to cause skeletal muscle contraction are called myofibrils. Myofibrils are composed of repeating units called sarcomeres, which contain thick and thin filaments made of proteins (actin and myosin). When the muscle fiber is stimulated by a nerve impulse, the myosin heads interact with the actin filaments to generate the force required for muscle contraction.
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
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
What is the name of small contractile elements of skeletal muscle fiber?
sarcomere
How is a skeletal muscle fiber stimulated by a motor neuron?
motor unitUnit
What are all muscle cells called?
A single muscle cell is called a muscle fiber.
What shape are skeletal muscle fibers?
Each fiber is actually a muscle cell. They are found in bundles that form what we call muscles. These are also called skeletal muscles because when they contract and get shorter, the bones that they are attached to, move. And the bones are part of the skeletal system.
