Sensory Systems Flashcards
What are the 5 sensory systems fish use to detect each other?
- Mechano reception
- Electro reception
- Vision
- Chemoreception
- Magnetic reception
What do these 5 sensory systems mean?
- Touch
- Detect Electricity
- See better in Water
- Taste
- Detect Magnetic Fields
Name the parts that fish use with their Mechano reception?
- Lateral Line System
- Inner Ear
- Neuromasts (Nerve cells) that detect vibrations
What are the functions of the Lateral Line System?
- Touching at a distance
- Schooling Behavior
- Predation
- Hydrodynamic Imaging
- Courtship Communication
- Subsurface Feeding
- Surface Wave Feeding
- Orientation
Where are the Otoliths located and their function?
- On sensory hair cells
2. Provide downward pull of gravity
Otoliths are also called what?
Bony/Ear Stones
What is the function of the Weberian Apparatus?
Transmit vibrations from gas bladder to the inner ear for detection by the Otolith Organs.
What are the sensory organs of Olfaction?
- Chambers
- Epithelia
- Taste Receptor Cells
What are the Olfaction Chambers made of and their function?
- Made of pits with epithelia and nerve snares covered with flap of skin
- Directs Water over the epithelia
What are the Olfaction Epithelia made of?
- Made of folded tissues in rosettes with chemo-receptor proteins
Taste Receptor Cells are often are clumped into what?
Taste Buds
What is the function of Ampullary Receptors?
Detect electrical currents
Why is salt water better for communication between fish?
Higher ionic concentration that makes it a good conductor of electricity
What do electrical organ discharges (EODs) use to send signals of electricity?
- Produce electrocytes
2. Modified muscle cells called electra plaques
Electrogenic Fish
Fish capable of generating an electric field
