What role do spindles play in mitosis?
Spindles are protein structures that help separate chromosomes during mitosis. They attach to chromosomes and help move them to opposite sides of the dividing cell, ensuring that each daughter cell receives the correct number of chromosomes.
The myotatic reflex is provoked by activation of What in a stretched muscle?
The myotatic reflex is provoked by activation of muscle spindles in a stretched muscle. These muscle spindles are sensory receptors that detect changes in muscle length and help regulate muscle contraction and body position. When a muscle is stretched, the muscle spindles send signals to the spinal cord, leading to a reflex contraction to prevent overstretching.
What is a spindle made of?
a spindle fiber is a specialized form of microtubules...that's what it is made of
These are barrel shaped microtubules in most animal cells that organize the spindles during cell division?
Centrioles are barrel-shaped microtubule structures found in animal cells that play a crucial role in organizing the spindle fibers during cell division. They are typically found in pairs near the nucleus and aid in chromosome segregation during mitosis and meiosis.
are Genes are located at specific positions on spindles?
spindle
What structures do the spindles originate?
Spindle fibers originate from structures called centrosomes, which are located at opposite poles of the cell during cell division. Each centrosome contains a pair of centrioles that help organize microtubules, forming the mitotic spindle. The spindle fibers are primarily composed of microtubules, which extend and attach to chromosomes at their kinetochores to facilitate their movement during mitosis.
Are spindles bipolar?
Yes, spindles are bipolar structures consisting of two poles. These poles help to separate chromosomes during cell division, ensuring equal distribution of genetic material to daughter cells.
What cell structures composed of microtuble fibers?
Microtubules are found in - cytoskeleton cilia flagella mitotic spindles
Hypocalcified structures of dentin?
Enamel tufts Enamel spindles Enamel lamellae Striae of Retzius Neonatal lines

What is the structure of mitosis?
Structures of mitosis include chromosomes, chormatids, centrioles, chromosome, and spindles. basically the things that are made and used for mitosis to occur
