Why don't neurons have centrioles?
Neurons are post-mitotic cells, meaning they no longer divide once they are fully developed. Centrioles are organelles responsible for organizing the mitotic spindle during cell division, so neurons do not require them. Additionally, the presence of centrioles in neurons could interfere with their specialized functions, such as long-distance signaling.
Most neurons lack centrioles This observation explains?
the inability of most neurons to undergo cell division. Centrioles are required for the organization of the mitotic spindle during cell division. Since neurons lack centrioles, they are unable to divide and are primarily post-mitotic cells.
Are neuroglia or neuron likely to give rise to tumor why?
Neuroglia are more likely to give rise to tumors, as they have the capacity to divide and undergo abnormal growth. Neurons, on the other hand, are post-mitotic cells and do not typically give rise to tumors. Tumors arising from neuroglia are known as gliomas.
Are neurons are able to divide?
No, you're thinking of Neuroglia

When neurons die why are they not replaced?
ALZHERMERS SYNDROME in simple terms In these diseases, neurons- the brain cells responsible for receiving, processing, and transmitting information- die and are not replaced. The current scientific literature makes one thing plain. As yet, there is no unifying hypothesis for the causes of Alzheimer's disease, Parkinson's disease, or many rarer degenerative brain diseases that cause dementia

A structure called the mitotic can be seen between the centrioles of animal cells when cells are reproducing?
The structure you are referring to is probably the mitotic spindle. The mitotic spindle is made up of microtubules and is responsible for organizing and segregating the chromosomes during cell division. It ensures that each daughter cell receives the correct number of chromosomes.

What is responsible for forming spindle during mitosis?
The centrioles within the cell form the mitotic spindle.
What structure is most closely associated with the production of the mitotic spindle?
The centrosome is most closely associated with the production of the mitotic spindle. It is responsible for organizing the microtubules that make up the spindle fibers during cell division.
In which cell there is no cell division?
In neurons. Also liver cells typically don't divide, but can start dividing if a serious damage is done to the liver.
Are neurons are able to divide?
No, you're thinking of Neuroglia
What cells would not divide using mitosis?
Cells that do not divide using mitosis include red blood cells (erythrocytes) and neurons in the brain. Red blood cells lack a nucleus, and neurons undergo a different process called mitotic division or neurogenesis to replace themselves.
