What is the difference between a muscle organ a muscle fiber myofibril and a myofilaments?
A muscle organ is made up of several muscle fibers, which are the individual cells that contract to produce movement. Each muscle fiber contains myofibrils, which are long, thread-like structures that run the length of the fiber and are responsible for contraction. Myofibrils are composed of myofilaments, the smallest units, which include actin (thin filaments) and myosin (thick filaments) that interact to facilitate muscle contraction. Together, these structures create the hierarchy of muscle organization from the whole muscle down to the molecular level.
As one muscle contracts the must relax.?
Yes. If not, the action at the joint will be incomplete and dysfunctional. As a whole, a muscle fiber is either contracted or relaxed (the all-or-none principal).
When a muscle fiber is subjected to a stimulus it contracts completely is called?
When a muscle fiber is subjected to a stimulus and contracts completely, this phenomenon is known as the "all-or-nothing response." In this response, if the stimulus reaches a certain threshold, the muscle fiber will contract fully; if it does not reach this threshold, there will be no contraction. This principle applies to individual muscle fibers, while whole muscles can exhibit varying degrees of contraction based on the number of fibers activated.
What is the difference between a whole number a?
A question about "the difference between" requires two objects!
What is the difference with muscle fiber and muscle tissue?
Muscle fibers are the individual, elongated cells that make up muscle tissue; they are responsible for the contraction and movement of muscles. Muscle tissue, on the other hand, is a collection of these muscle fibers grouped together, functioning as a whole to perform specific actions. There are three types of muscle tissue in the body: skeletal, cardiac, and smooth, each with distinct functions and characteristics. In summary, muscle fibers are the building blocks, while muscle tissue is the collective structure formed by these fibers.
What is the difference between a diameter and a radius?
A diameter is a whole line and a radius is just half not a whole that is the difference
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.
What are the difference between comparing whole number and comparing decimals?
There is no difference.
The difference between two whole numbers is always a whole number?
True.
Is the difference between 2 whole numbers always a whole number?
Yes, it is.
What are the difference between integer and a whole number?
There are no differences.
What is the difference between 0.3 and 3.0?
0.3 is not a whole number and 3.0 is a whole number
