Afferences
Afferent means to lead there, which is what nerves or blood vessels are called.
Afferences, for example, denote the totality of all the things that are described by the periphery (sensory organ, receptor) to the central nervous system (CNS) in more highly developed animals.
In German-speaking anatomy, a distinction is often made between sensitive (concerning the sense of touch) and sensory (concerning sensory perception) afferences, although this subdivision is not very meaningful. The counterpart to afferences are the efferences that direct nerve impulses in the opposite direction.
