sensory canal

sensory canal
lateral line (a tube-like sensory organ (usually bearing pores) extending along the side of the body. Detects water movements, low frequency vibrations and perhaps temperature changes. In some fishes the sensory organs are uncovered (without a tube or pores). The lateral line is innervated by the vagus or Xth cranial nerve. The similar sensory system on the head, often called the cephalic sensory canals, is differently innervated. Lateral lines may be single, multiple, complete (extend to the base of the caudal fin) or incomplete, have accessory branches, be decurved, recurved, arched. etc.)
