What is a lateral line system in fish?
The lateral line is a sensory system that allows fishes to detect weak water motions and pressure gradients.
What is lateral line system Slideshare?
The lateral line system consists of 100 or more sensory organs (neuromasts) that are typically arranged in lines on or just under the skin of the head and body.
Why is the lateral line important?
The lateral line functions to detect vibrations and water movement and allows fish to orientate themselves in a water current (rheotaxis), gain information about their spatial environment, and also plays a vital role in schooling (see also HEARING AND LATERAL LINE | Lateral Line Structure).
What is a lateral line system biology?
The lateral line system consists of 100 or more sensory organs (neuromasts) that are typically arranged in lines on or just under the skin of the head and body. Neuromasts are composed of sensory hair cells, which are also found in the auditory system of all vertebrates.
What is lateral line system class 11?
Lateral line system is a system of tactile sense organs, unique to aquatic. vertebrates from cyclostome fishes (lampreys and hagfish) to amphibians. It is made up of a series of mechanoreceptors called neuromasts (lateral line organs) derived from ectoderm arranged in an interconnected network along the head and body.
What is the function of the lateral line in fishes quizlet?
The lateral line is a system of sense organs found in aquatic vertebrates, used to detect movement and vibration in the surrounding water. Lateral lines serve an important role in schooling behavior, predation, and orientation.
Do cartilaginous fish have a lateral line?
Related to sound reception is the lateral line canal system of cartilaginous fishes and other aquatic vertebrates, a network of tubes below the skin, with several branches on the head but with a single line, the lateral line proper, running along the body on both sides and extending to the caudal fin.
Do all fish have a lateral line?
All fish have some form of a lateral line, some having a more developed one than others. Lateral lines are usually visible as faint lines running lengthwise down each side, from the vicinity of the gill covers to the base of the tail.
Where is the lateral line found what is its job?
The lateral line, also called the lateral line organ (LLO), is a system of sensory organs found in fish, used to detect movement, vibration, and pressure gradients in the surrounding water.
What is the function of the lateral line in Sharks quizlet?
The lateral line allows the shark to orient to particle movement or sound. It consists of structures called neuromasts which are located in canals that lie just below the surface of the skin or the scales.
Do all fish have lateral line?
Which part of the fish is most commonly used to propel high speed fish?
They propel themselves through water by using their rear flippers.
What is the lateral line system in fish?
The lateral line system is a way of detecting wave energy as it passes over, or bounces off, the fish’s body. It works using mechanoreceptors similar to those responsible for the senses of hearing and balance.
How is the lateral line system of elasmobranchs different from teleost fish?
The lateral line system of elasmobranchs is different to that of teleost fish. Elasmobranchs have superficial neuromasts and two morphological classes of sub-epidermal canals. Elasmobranch canals have skin pores that allow direct contact with the surrounding water.
What is the structure of the lateral line?
As the structure between these two systems is similar the author determined that the lateral line was derived from pore a canal system, and then became a specialized part of it and later remained there (Denison 1966). The lateral line, consists of a row of small pores which lead into the underlying lateral line canal.
Does foul water attract lateral-lineorgans in fish?
FUNOTION OF LA’J’ERAL-LINEORGANS IN FISHES.195 behaved as though they were in ordinary sea water, and hence the general condition of foul water could not be said to afford a stimulus for the lateral-lineorgans.
