simplest neural network 3 cells: a sensory neuron connected to a motor neuron connected to a muscle cell neural network of human brain 10^11 neurons and 10^14 synapses. the neurons and synapses of the human brain are divided into thousands of distinct but interacting networks that function in parallel neurons specialized cells of the nervous system that receive, encode, and transmit information nervous systems made up of neurons and their support cells (glial cells) glial cells They are support cells for neurons. These cells may support and orient neurons or insulate axons. Glial cells and oligodendrocytes do the latter. sensory cells modified neurons that transduce (ie, convert) stimuli into electrical signals: action potentials. effectors muscles and glands that respond to the signal received by the nervous system. the nervous system got the signal from sensory cells. nerve net A simple network of neurons that is how simple animals transfer information. A direct line from sensory cell to the effector. ganglia clusters of neurons in a nervous system slightly more complex than a nerve net. brain the largest and most complex ganglion (cluster of neurons) central nervous system CNS. Brain and spinal cord, where most of the cells of the nervous system are found in vertebrates. Peripheral nervous system
