Neuroeffector junction
Neuroeffector Junction
Neuroeffector junction (pronunciation: /ˌnʊəroʊɪˈfɛktər ˈdʒʌŋkʃən/) is a specialized area of contact where a neuron communicates with an effector cell to elicit a physiological response.
Etymology
The term "neuroeffector junction" is derived from the combination of "neuro", from the Greek word "neuron" meaning nerve, and "effector", which refers to a muscle or gland cell that performs an action in response to a signal.
Function
The primary function of a neuroeffector junction is to transmit signals from the nervous system to the effector cells. This is achieved through the release of neurotransmitters from the neuron, which bind to receptors on the effector cell, triggering a response.
Types
There are two main types of neuroeffector junctions: neuromuscular junctions, where neurons communicate with muscle cells, and neuroglandular junctions, where neurons communicate with gland cells.
