Astrocytes express a range of receptors and ion channels that are similarly expressed in neurons Verkhratsky et al. 1998.At most glutamatergic central synapses the extremity of protoplasmic astrocyte process wraps the synaptic cleft and communicates with pre- and post-synaptic neurons forming what is called a tripartite synapse
Operations in many different industries can create explosive atmospheres that present a great danger to both life and equipment. In the chemical and petrochemical industries these are caused primarily by flammable gases vapors or mists. In mining mills and other areas dust can combine with the air to become highly explosive. Unsafe equipment can ignite these mixtures resulting in explosions
