What are the functions of sensory nerve terminals?
Peripheral sensory nerve terminals have multiple functions: reporting normal and abnormal sensations, releasing transmitter substances in response to local factors, and releasing trophic factors to maintain the structure and function of cells in their local environment (e.g., epithelial cells). Signal detection by nerve terminals varies based on location, morphology or type of ending (e.g., encapsulated vs. free nerve endings), and molecular receptor properties. Sensory terminals are populated with specialized receptors that transduce stimuli (e.g., thermal, mechanical, and chemical) into electrical potentials which generate action potentials in their parent axons. Action potentials are propagated through neurites to communicate the modality and intensity of stimuli toward neuron somas and to the CNS. The physiology of these endings is usually dependent on intracellular [Ca2+ ]. Generally, nociceptors are free nerve endings; mechanoreceptors or touch receptors show some type of encapsulation and are located in cutaneous and subcutaneous regions, and receptors located in muscle, joints, and deep structures monitor mechanical forces as proprioceptors.
