Visceral Afferent - an overview ScienceDirect Topics

WebbVisceral afferents (slow conducting fibers) tend to predominate in parasympathetic nerves, but there are fewer of them in sympathetic nerves. For example, 90% of the fibers in the vagus nerve are sensory compared with 20% in the greater splanchnic nerve. However, pelvic visceral pain returns to the spinal cord primarily via the sympathetic ... There are two main parts of the spinothalamic tract: • The lateral spinothalamic tract transmits pain and temperature. • The anterior spinothalamic tract (or ventral spinothalamic tract) transmits crude touch and firm pressure.
