A bipolar cell is a type of neuron which has two extensions. This is a list of the subjects in Gray's Anatomy: IX Neurology Elsevier, the world's largest Publisher of Medical and Scientific literature, forms part of the Reed Elsevier group Neurons (ˈnjuːɹɒn also known as neurones and nerve cells) are responsive cells in the Nervous system that process and transmit information Bipolar cells are specialized sensory neurons for the transmission of special senses. As such, they are part of the sensory pathways for smell, sight, taste, hearing and vestibular functions.
The most common examples are the bipolar cell of the retina, and the ganglia of the vestibulocochlear nerve. As a part of the Retina, the bipolar cell exists between photoreceptors ( Rod cells and Cone cells and Ganglion cells They act to The vestibulocochlear nerve (also known as the auditory or acoustic nerve) is the eighth of twelve Cranial nerves, and is responsible for transmitting sound [1] When used without further detail, the term usually refers to the retinal cells.
Bipolar cells are also found in the spinal ganglia, when the cells are in an embryonic condition. In Anatomy and Neurology, the dorsal root Ganglion (or spinal ganglion) is a nodule on a Dorsal root that contains cell bodies of An embryo (from Greek:, plural, lit "that which grows" from en- "in" + bryein "to swell be full" is a multicellular
They are best demonstrated in the spinal ganglia of fish.
Sometimes the extensions, also called "processes", come off from opposite poles of the cell, and the cell then assumes a spindle shape; in other cells both processes emerge at the same point. In Anatomy, a process ( Latin: processus) is a projection or outgrowth of tissue from a larger body
In some cases where two fibers are apparently connected with a cell, one of the fibers is really derived from an adjoining nerve cell and is passing to end in a ramification around the ganglion cell, or, again, it may be coiled spirally around the nerve process which is issuing from the cell.
