What is the role of the spindle fibers?
Spindle-shaped muscle fibers are skeletal muscles that produce external mobility to the body.

What is role of spindle fibers in mitosis?
They pull the sister chromatids apart.
What is the role of spinder fibers?
Spindle fibers are responsible for organizing and separating chromosomes during cell division. They help to ensure that each new cell receives the correct number of chromosomes. Additionally, spindle fibers play a key role in the movement of chromosomes to opposite poles of the cell during both mitosis and meiosis.
What vitamin has an important role in the formation of collegen fibers and prevention of scurvy?
Vitamin C
Unmyelinated nerve fibers are known as?
Unmyelinated nerve fibers are known as C fibers. These fibers are characterized by their slow conduction velocity and are typically involved in transmitting pain, temperature, and certain autonomic functions. Unlike myelinated fibers, C fibers lack the insulating myelin sheath, which contributes to their slower signaling properties. They play a crucial role in the body's response to noxious stimuli.
What are spindle fibers composed of?
Spindle fibers are composed of microtubules, which are polymers of the protein tubulin. These microtubules play a crucial role in cell division by helping to separate the chromosomes during mitosis and meiosis.
What is the role of slow muscle fibers and fast muscle fibers in the response of a muscle to different types of exercise?
There are two broad types of voluntary muscle fibers: slow twitch and fast twitch. Slow twitch fibers contract for long periods of time but with little force while fast twitch fibers contract quickly and powerfully but fatigue very rapidly.
What is the role of cotton in making artificial fibers?
the role of cotton in making artificial fibres, it makes the fibre more flexible and smooth. Water absorbent.
Cell structures made of individual microtube fibers that are involved in moving chromosomes during cell division are called?
Spindle fibers. These structures form the mitotic spindle and play a crucial role in separating chromosomes during cell division.
What are the Fibers of ventricular bundle?
The fibers of the ventricular bundle, also known as the bundle of His, are specialized cardiac muscle fibers that conduct electrical impulses from the atrioventricular (AV) node to the Purkinje fibers in the ventricles. These fibers play a critical role in coordinating the contraction of the ventricles during the cardiac cycle, ensuring effective pumping of blood out of the heart.
What is the role of collagen fibers in maintaining the elasticity and firmness of the skin?
Collagen fibers play a crucial role in maintaining the elasticity and firmness of the skin. They provide structural support and help the skin maintain its shape and strength. As we age, the production of collagen decreases, leading to sagging and wrinkles.
