WebThe basic building block of the nervous system is a nerve cell, or neurone. Neurones are shaped differently depending on where they are in the body and what role they play. All neurones have finger-like projections called dendrites and a long fibre called an axon. In many cases, the axon is coated by a specialised membrane called a myelin sheath. WebSep 21, 2016 · Neurons are connected to each other through synapses, sites where signals are transmitted in the form of chemical messengers. Reinhard Jahn, Director at the Max Planck Institute for Biophysical Chemistry in Göttingen, has investigated precisely how the process works. Fig. 1: Illustration of a neuron (left) and a synapse (right). WebThe peripheral nervous system (PNS) is made up of nerves and ganglia (clusters of nerve cells). The PNS and CNS work together to send information between the brain and the rest of the body. Nerves emerge from the CNS through the skull and vertebral column, using the PNS to carry information to the rest of the body. eds with sleep study
