If you look at certain pictures taken of the spindles/an artists representation of them, you will find that the nucleus, the mitochondria, and the Golgi Apparatus all play a significant role in mitotic spindles.
The mitotic apparatus is primarily composed of the mitotic spindle, which consists of microtubules that form a network to separate chromosomes during cell division. Key components include spindle fibers, which are organized by centrosomes, and motor proteins that help in the movement of chromosomes. Additionally, the mitotic apparatus includes kinetochores, which are protein structures on the chromosomes that attach to spindle fibers. Together, these components ensure accurate chromosome alignment and segregation during mitosis.
To remove the key from the spindle nut, first loosen the nut using the appropriate tool. Once the nut is loose, slide the key out of the keyway on the spindle shaft by grasping it firmly and pulling it out. Be cautious not to damage the key or the spindle during this process.
During prophase of mitosis, several key cell parts migrate to the poles. The centrosomes, which organize the mitotic spindle, move to opposite poles of the cell. Additionally, spindle fibers, made of microtubules, extend from the centrosomes and begin to attach to the chromosomes. This organization is crucial for the proper separation of chromosomes in later stages of cell division.
The centrioles are found in a region of the cytoplasm called the centrosome. This area is crucial for organizing microtubules and plays a key role in cell division by helping to form the mitotic spindle. The centrosome typically contains a pair of centrioles arranged perpendicularly to each other.
The combination of mitotic cyclin with cyclin-dependent kinase (CDK) signals the cell to enter mitosis, initiating the process of cell division. This complex activates CDK, leading to the phosphorylation of target proteins that promote chromatin condensation, spindle formation, and other key events necessary for mitosis. The precise regulation of this cyclin-CDK complex is crucial for ensuring that the cell divides accurately and at the appropriate time in the cell cycle.
The centriole is the organelle that has 13 rows of tubulin dimers around an empty central core. It plays a key role in cell division by organizing the mitotic spindle apparatus.

Centrosome. It is a pair of centrioles plus pericentriolar material. The pericentriolar material contains tubulins, which are used for growth of the mitotic spindle and microtubule formation. The mitotic spindle are used in reproduction. Reference: Principles of Anatomy and Physiology. 12th Ed. Author: Tortora, Derrickson.
The centrosome is a cellular organelle that plays a key role in organizing the microtubules during cell division. It helps in the formation of the mitotic spindle, which is essential for the separation of chromosomes during cell division. Additionally, the centrosome is involved in cell motility and maintaining cell shape.
The centrioles are located in the centrosome. They play a key role in organizing the microtubules during cell division and are important for the formation of the mitotic spindle.
centrosome. It is an organelle found near the nucleus in animal cells and plays a key role in cell division by organizing and anchoring the microtubules that form the mitotic spindle. This structure helps ensure that replicated chromosomes are properly segregated into daughter cells during cell division.
The organelle near the nucleus that helps with reproduction is the centriole. Centrioles play a key role in cell division by organizing the mitotic spindle, which is crucial for separating chromosomes during cell division.
The centrosome is a crucial organelle in animal cells, primarily responsible for organizing microtubules and playing a key role in cell division. It consists of a pair of centrioles surrounded by a proteinaceous matrix known as the pericentriolar material. During mitosis, the centrosome helps to form the mitotic spindle, ensuring the proper separation of chromosomes. Additionally, centrosomes are involved in maintaining cell shape and facilitating intracellular transport.

Kinetochores are protein structures located at the centromere region of a chromosome. They play a key role in the attachment of chromosomes to the microtubules of the mitotic spindle during cell division. Errors in kinetochore function can lead to chromosome mis-segregation and genetic abnormalities.
