What maintains the tension in a muscle spindle?
The tension in a muscle spindle is maintained by intrafusal muscle fibers, which are specialized muscle fibers within the spindle that are innervated by sensory nerve fibers. These sensory fibers detect changes in muscle length and transmit signals to the central nervous system to regulate muscle tone and coordination.
What are long fibers called?
Muscle cells are called fibers.
What is it called when white muscle fibers that contract quickly?
Fast-twitch muscle fibers.
Which sensory receptor is sensitive to change in tension of a muscle?
proprioceptors
What are individual muscle cells called?
Individual muscle cells are called muscle fibers or myofibers. These elongated cells are specialized for contraction and come in three types: skeletal, cardiac, and smooth muscle fibers, each serving different functions in the body. Skeletal muscle fibers are responsible for voluntary movements, cardiac muscle fibers make up the heart, and smooth muscle fibers are found in the walls of hollow organs.
What do you call the natural tension in the fibers of a muscle?
muscle tone

What is a muscle cell called?
The scientific name for a muscle cell is a myocyte. Myocytes are also sometimes called muscle fibers. They are long, tube shaped, cells that develop from myoblasts.
What is muscle cell called?
fibers
What are bundles of muscle fibers?
myofibril
Which sensory receptor is sensitive to change in tension of a muscle?
proprioceptors
What happen when muscles shorten?
What happens when a muscle shortens is that it is contracting. This is when the fibers of the muscles generate tension.

Skeletal muscle fibers are responsible for voluntary movements, cardiac muscle fibers make up the heart, and smooth muscle fibers are found in the walls of hollow organs.
What can the nervous system do to increase muscle tension?
The nervous system can increase muscle tension through the recruitment of motor units and the frequency of action potentials sent to the muscles. When more motor neurons are activated, additional muscle fibers contract, leading to greater force production. Additionally, increasing the rate of stimulation (temporal summation) can enhance muscle tension by allowing muscle fibers to contract more forcefully before they have a chance to relax. This coordinated control allows for precise adjustments in muscle tension to meet various demands.
An increase in muscle fibers is called?
smd
