An excitatory synapse is a synapse in which an action potential in a presynaptic neuron increases the probability of an action potential occurring in a postsynaptic cell. Neurons form networks through which nerve impulses travel, each neuron often making numerous connections with other cells.
Supplement. A biological synapse involving neurons can be: (1) Chemical synapse: the junction between neurons such that the nerve impulse is transmitted from a neuron to another neuron or to a muscle cell or gland cell.(2) Electrical synapse: the gap junction between two apposed neurons that allows faster nerve transmission.Recently, a biological synapse not involving a neuron is found to exist. The junction between a lymphocyte and an antigen-presenting cell is referred to as immunological synapse. biological synapse involving neurons can be: (1) Chemical synapse: the junction between neurons such that the nerve impulse is transmitted from a neuron to another neuron or to a muscle cell or gland cell.
