What 3 Apparatus are found in the Ommatidia?
What two things are found in the Focusing Apparatus
- Corneal Lens - Top
- Crystalline Cone - Middle
What is Found in the Receptor Apparatus?
- Retinula cells- Middle Line
- Rhabdom-Inner Middle Line
- Axon- Bottom
- Rhodopsin-detects light
What is Found in the Isolating Apparatus?
Primary and Secondary Pigment cells
-Focus Light on the Rhabdom
What Reflects ligh back into the ommatidia and is formed by the trachea, usually found in moths?
Dark adapted eyes have what, which results in what?
Clear Zone-between Crystalline Cone and Rhabdom
Results in Increased Sensitivity to light but Decrease Resolution
What is the Color Range?
Red to Ultraviolet
What range do most Insects See?
Yellow to Ultraviolet
What is the Number of images that can be detected per second?
Flicker Fusion Frequency
What is Used in Navigation
Plane of Polarization
What are the 3 Parts to Image Formation (Mosaic theory)
Individual ommatidia contribute to overall picture
Individual Points of Light put together in brain
Image Right-side Up
What is the Angle of light entering the ommatidium called what angle is it in insects and humans
Human = 1/90 degrees
Retinula Cells detect light and send information where?
Optic lobe of Brain
What detects and mechanical stress placed on the body and is involved in detecting position of extremities and Sensilla?
What Detects extremities?
What detects Sensilla?
Bipolar neuron that is attached to cuticle
What are the 3 basic types of Mechanosensilla, whatis there form?
Trichoid -Hair like Setae
Campaniform - Dome-Like cuticle
Chordotonal - Internal
What Monitors stress placed on cuticle
What is the organ of hearing and detects vibrations?
What are the 4 Different factors of Chordotonal?
- Positioned anywhere on the body
- Johnstons organ-Male Mosquito
- Subgenual organ-Below Knee grasshopper
- Tympanal Organ
Where are the Auditory Trachea and Trachea found in subgenual organ?
- Middle Chamber
- Outside wall

In Chemosensilla Receptors on the Dendrites are found where?
What are some important things about chemosensilla?
- One Pore Through top of Cuticle
- Located on mouthparts tarsi and antennae
- Requires contact with food
In Chemical Communication what is the Releaser and the Reveiever?
Source that releases chemical
