What is the significance of the skeletal muscle fiber triad relationship?
The skeletal muscle fiber triad relationship refers to the structural arrangement of a T-tubule sandwiched between two terminal cisternae of the sarcoplasmic reticulum. This triad structure plays a crucial role in excitation-contraction coupling, as it allows for the transmission of action potentials deep into the muscle fiber to trigger calcium release from the sarcoplasmic reticulum for muscle contraction.
What is the multinucleate muscle fiber?
Skeletal
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 primary role of muscle spindles?
the striated portions of the intrafusal fiber contract to keep the spindle taut at different muscle lengths. If the whole muscle is stretched, the muscle spindle is also stretched, triggering sensory nerve impulses on its nerve fiber. These sensory fibers synapse in the spinal chord with lower motor neurons leading back to the same muscle. Impulses triggered by stretch of the muscle spindle contract the skeletal muscle.
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
What is the function of motor end plate?
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.
How are the Neuron and skeletal muscle fiber connected?
they are connected with the rope in the body
