  2. Cell cycle checkpoint - Wikipedia

    en.wikipedia.org/wiki/Cell_cycle_checkpoint

    Cell cycle checkpoints are control mechanisms in the eukaryotic cell cycle which ensure its proper progression. Each checkpoint serves as a potential termination ...

  3. Neuronal cell cycle - Wikipedia

    en.wikipedia.org/wiki/Neuronal_cell_cycle

    The Neuronal cell cycle represents the life cycle of the biological cell, its creation, reproduction and eventual death. The process by which cells divide into two daughter cells is called mitosis . Once these cells are formed they enter G1, the phase in which many of the proteins needed to replicate DNA are made.

  4. Cytoarchitecture - Wikipedia

    en.wikipedia.org/wiki/Cytoarchitecture

    Defining cerebral cytoarchitecture began with the advent of histology—the science of slicing and staining brain slices for examination. [2] It is credited to the Viennese psychiatrist Theodor Meynert (1833–1892), who in 1867 noticed regional variations in the histological structure of different parts of the gray matter in the cerebral hemispheres.

  5. Anatomy of the cerebellum - Wikipedia

    en.wikipedia.org/wiki/Anatomy_of_the_cerebellum

    The human cerebellum is located at the base of the brain, with the large mass of the cerebrum above it, and the portion of the brainstem called the pons in front of it. It is separated from the overlying cerebrum by a layer of tough dura mater called the cerebellar tentorium; all of its connections with other parts of the brain travel through the pons.

  6. Spindle checkpoint - Wikipedia

    en.wikipedia.org/wiki/Spindle_checkpoint

    Absence of p53, the most commonly mutated gene in human cancer, has a major effect on cell cycle checkpoint regulators and has been shown to act at the G1 checkpoint in the past, but now appears to be important in regulating the spindle checkpoint as well. [76] Another key aspect of cancer is inhibition of cell death or apoptosis.

  7. Human brain - Wikipedia

    en.wikipedia.org/wiki/Human_brain

    Betz cells are the largest cells (by size of cell body) in the nervous system. [40] The adult human brain is estimated to contain 86±8 billion neurons, with a roughly equal number (85±10 billion) of non-neuronal cells. [41] Out of these neurons, 16 billion (19%) are located in the cerebral cortex, and 69 billion (80%) are in the cerebellum ...

  8. ATM serine/threonine kinase - Wikipedia

    en.wikipedia.org/wiki/ATM_serine/threonine_kinase

    The cell cycle has different DNA damage checkpoints, which inhibit the next or maintain the current cell cycle step. There are two main checkpoints, the G1/S and the G2/M, during the cell cycle, which preserve correct progression. ATM plays a role in cell cycle delay after DNA damage, especially after double-strand breaks (DSBs). [10]

  9. Hippocampal subfields - Wikipedia

    en.wikipedia.org/wiki/Hippocampal_subfields

    The region is conventionally divided into three divisions. CA3a is the part of the cell band that is most distant from the dentate (and closest to CA1). CA3b is the middle part of the band nearest to the fimbria and fornix connection. CA3c is nearest to the dentate, inserting into the hilus.
