The appendix has been identified as an important component of mammalian mucosal immune function, particularly B cell-mediated immune responses and extrathymically derived T cells. This structure helps in the proper movement and removal of waste matter in the digestive system, contains lymphatic vessels that regulate pathogens, and lastly, might ...
Brain cells make up the functional tissue of the brain. The rest of the brain tissue is the structural stroma that includes connective tissue such as the meninges , blood vessels , and ducts. The two main types of cells in the brain are neurons , also known as nerve cells, and glial cells , also known as neuroglia. [ 1 ]
The firing of place cells is timed in relation to local theta waves, a process termed phase precession. [85] Cells with location-specific firing patterns have been reported during a study of people with drug-resistant epilepsy. They were undergoing an invasive procedure to localize the source of their seizures, with a view to surgical resection.
Since the brain regions are so specialized in their functioning, damages done to specific areas of the brain can cause specific type of damage. Damage to the left side of the brain can lead to language discrepancies, i.e. difficulty in properly identifying letters, numbers and words, inability to incorporate visual stimuli to comprehend ...
Ileum, caecum and colon of rabbit, showing Appendix vermiformis on fully functional caecum The human vermiform appendix on the vestigial caecum. The appendix was once believed to be a vestige of a redundant organ that in ancestral species had digestive functions, much as it still does in extant species in which intestinal flora hydrolyze cellulose and similar indigestible plant materials.

According to Kukushkin, the memories stored in non-brain cells in other parts of the body are memories strictly related to the roles that those specific cells play in human health. Thus, he detailed:
When it comes to flying under the radar, the appendix is in the running for the top spot. In a 2007 study researchers from Duke University said it helps store good microbes or bacteria that help ...
Glial cells maintain homeostasis, produce myelin (oligodendrocytes, Schwann cells), and provide support and protection for the brain's neurons. Some glial cells can even propagate intercellular calcium waves over long distances in response to stimulation, and release gliotransmitters in response to changes in calcium concentration. Wound scars ...
