What else can I help you with?
The repeating unit of a skeletal muscle fiber is the?
Myofibrils The sarcomere is the unit of muscular contraction.
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.
What is the multinucleate muscle fiber?
Skeletal
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
What is the specific relationship of the functional unit of contraction to the striated appearance of a skeletal muscle fiber?
The organization of contractile proteins into a regular end-to-end repeating pattern of sacromeres along the length of each cell accounts for the striated, or striped, appearance of skeletal muscle in longitudinal section.
The cytoplasm of a skeletal muscle fiber is called the?
Sarcoplasm
What is the correct sequencing of the microstructure of skeletal muscle?
muscle fiber, myofibril, myofilaments, sarcomere
The smallest functional unit of the muscle fiber?
The smallest functional unit of a muscle fiber is the sarcomere. Sarcomeres are composed of actin and myosin filaments arranged in a repeating pattern, allowing for muscle contraction and relaxation to occur. They are responsible for the striated appearance of skeletal muscle under a microscope.
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
