tuberous electoreceptor organs for detecting perturbations in it's own electric ?eld. Each electroreceptor organ consists of a small (approx 0.1 mm diameter)... 5 animal. Within the electric organ, net sodium flux in the headward direction polarizes the fish’s head positive relative to the tail (Fig. 2).
The Electric Organ Discharges of the Gymnotiform Fishes
The electric eel ( Electrophorus electricus ) is unusual among electric fishes because it has three pairs of electric organs that serve multiple biological functions: For navigation and communication, it emits continuous pulses of weak electric discharge (<1 V), but for predation and defense, it intermittently emits lethal strong electric... tuberous electoreceptor organs for detecting perturbations in it's own electric ?eld.

This chapter focuses on electric fish research during the 19th century. These studies would involve attempting to get sparks from torpedoes, determining the polarity of the electric organs, trying to understand why these fish did not electrocute themselves, and much more. Fish studies and research on nerve and muscle physiology would be viewed scope of employee engagement pdf The electrocytes of most 'electric fishes' are modified muscle cells. Electrocytes are usually arranged in columns within electric organs. This arrangement increases the electrical output, much like a row of batteries placed end to end.
Genomic basis for the convergent evolution of electric organs
The electric catfish of Africa, the knife fish of Latin America, and the stargazers probably use their bioelectric organs as sense organs in the detection of other fishes. The basic element of an electric organ is a flattened cell called an electroplaque . inorganic chemistry principles of structure and reactivity huheey pdf The electric organs of fishes A number of different types of fish are capable of producing appreciable electric currents in the water surrounding them. These currents are produced by special organs known as electric organs. The position of the electric organs in vari- ous electric fish is shown in fig. 15. l. Electric organs are composed of columns of cells called electroplaques (sometimes

The electric organs (main, Sachs' and Hunter's) of a 23 cm and a 38 cm long Electrophorus electricus were studied by histological methods. The results were compared with 12 cm (Keynes, '61) and 140 cm (Couceiro and Ackermann, '48) specimens. All three electric organs originate from striated muscle fiber as indicated by the presence of a striated structure in the undeveloped electroplates. The
- Longitudinal section of E. electricus showing location and relative size of the three electric organs along with other anatomical features. Mentions: Over 700 species of electric fishes have been identified , the vast majority of which are capable of generating only weak electric organ discharges (EOD) for the purpose of navigation and communication.
- 1/05/1999 · Abstract: Weakly electric fish use active electrolocation - the generation and detection of electric currents - to explore their surroundings. Although electrosensory systems include some of the most extensively understood circuits in the vertebrate central nervous system, relatively little is known quantitatively about how fish
- Electric organs, found in six groups of fishes (Fig. 1), are structures specialized to generate electric fields in the animals’ external environment. In some the voltages are large enough to stun prey or repel predators. These, the strongly electric fishes, include the electric eel
