NEUROEFFECTOR JUNCTION

Definition and Fundamental Role of the Neuroeffector Junction The neuroeffector junction (NEJ) is a specialized anatomical and physiological interface where a neuron, typically a postganglionic fiber of the autonomic nervous system, communicates with a non-neuronal target cell, known as an effector. These effectors encompass a diverse range of tissues, including smooth muscle, cardiac muscle, and […]

POSTGANGLIONIC AUTONOMIC NEURON

Defining the Postganglionic Autonomic Neuron The postganglionic autonomic neuron constitutes the second element in the two-neuron chain characteristic of the autonomic nervous system (ANS). This specialized neuron is fundamentally responsible for transmitting the efferent signal from the central nervous system (CNS) to the terminal effector organ, thereby mediating involuntary control over vital bodily functions. Specifically, […]
