(cytology) A cell of the nervous system, which conducts nerve impulses; consisting of an axon and several dendrites. Neurons are connected by synapses.
(anatomy) The basic structural and functional unit of the kidney, which filters the blood in order to regulate chemical concentrations, and thereby produces urine.
(zoology) A nervure of an insect's wing.
any of the small tubules that are the excretory units of the vertebrate kidney
The brain and spinal cord; the cerebro-spinal axis; myelencephalon.
The nephron is the minute or microscopic structural and functional unit of the kidney. It is composed of a renal corpuscle and a renal tubule.
The characteristic specialized cell that is part of the nervous system, serving to conduct electrical impulses to and from the brain, and also between other parts of the body, and composed of a main cell body, the axon, with a varying number of processes of varying length, the dendrites; a nerve cell. The movement and behavior of higher animals depends on the signals tranmsitted by such nerve cells.
a cell that is specialized to conduct nerve impulses
A neuron or nerve cell is an electrically excitable cell that communicates with other cells via specialized connections called synapses. It is the main component of nervous tissue in all animals except sponges and placozoa.
