And you would be right in just about every instance. But for veterans with service-connected disability ratings, the math doesnât always work out quite so easily. In fact, 30 + 20 might only equal 44, which rounds down to 40. Or it might equal 48.4, which rounds up to 50.
Exteroceptors are the afferent nerve endings that sense stimuli originating from outside of the body, such as pain, touch, vibration, temperature, and sound. One type of exteroceptors are known as mechanoreceptors, which are receptors that respond to external mechanical stimuli such as touch, pressure, and vibration.
Autonomic nerves, in contrast to somatic nerves, have an additional synapse between the central nervous system and the innervated structure (end organ). These synapses are in structures called ganglia, and these are nerve-to-nerve junctions instead of nerve-to-end organ junctions.
