Cajal body. Cajal bodies (CBs), also coiled bodies, are spherical nuclear bodies of 0.3–1.0 μm in diameter found in the nucleus of proliferative cells like embryonic cells and tumor cells, or metabolically active cells like neurons. CBs are membrane-less organelles and largely consist of proteins and RNA.
Interstitial cells of Cajal (ICC) are interstitial cells found in the gastrointestinal tract.There are different types of ICC with different functions. ICC and another type of interstitial cell, known as platelet-derived growth factor receptor alpha (PDGFRα) cells, are electrically coupled to smooth muscle cells via gap junctions, that work together as an SIP functional syncytium.

Cajal–Retzius cells (CR cells) (also known as Horizontal cells of Cajal) are a heterogeneous population of morphologically and molecularly distinct reelin-producing cell types in the marginal zone/layer I of the developing cerebral cortex and in the immature hippocampus of different species and at different times during embryogenesis and postnatal life.
Santiago Ramón y Cajal (Spanish: [sanˈtjaɣo raˈmon i kaˈxal]; 1 May 1852 – 17 October 1934) [1][2] was a Spanish neuroscientist, pathologist, and histologist specializing in neuroanatomy and the central nervous system. He and Camillo Golgi received the Nobel Prize in Physiology or Medicine in 1906. [3] Ramón y Cajal was the first person ...
Consequently, cellular bodies that form through liquid–liquid phase separation are a subset of biomolecular condensates, as are those where the physical origins of assembly are unknown. Historically, many cellular non-membrane bound compartments identified microscopically fall under the broad umbrella of biomolecular condensates.
The basal or basic electrical rhythm (BER) or electrical control activity (ECA) is the spontaneous depolarization and repolarization of pacemaker cells known as interstitial cells of Cajal (ICCs) in the smooth muscle of the stomach, small intestine, and large intestine. This electrical rhythm is spread through gap junctions in the smooth muscle ...
Frontopontine fibers. The medial longitudinal fasciculus (MLF) is a prominent bundle of nerve fibres which pass within the ventral/anterior portion of periaqueductal gray of the mesencephalon (midbrain). [1] It contains the interstitial nucleus of Cajal, responsible for oculomotor control, head posture, and vertical eye movement.
Astrocytes (from Ancient Greek ἄστρον, ástron, "star" and κύτος, kútos, "cavity", "cell"), also known collectively as astroglia, are characteristic star-shaped glial cells in the brain and spinal cord. They perform many functions, including biochemical control of endothelial cells that form the blood–brain barrier, [5] provision ...
