19 important questions on Case 7; dog - aantekeningen
(true or false) the eye contains 3 types of cones, one of which is for seeing yellow light?
The image is a schematic overview of the eye. A number of structures of the eye are indicated by an arrow with the letter A through D. Onn which structure are the cones and the rods?
(true or false) frequenncies around 400 hz are easy to hear for people
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
How big is the surface of the olfactory membrane in the dog?
What is the meaning of vision and in which 3 steps can it be divided?
- 3 steps:
1. Light enters the eye, and the lens focuses light on the retina
2. Photoreceptors of the retina transduce light energy into an electrical signal
3. Neural pathways form retina to brain process electrical signals into visual images
What kind of basic structure does the rods and cones have?
2. An inner segment that contains the cell nucleus and organelles fo ATP and protein synthesis
3. A basal segment with a synaptic terminal that releases glutamate onto bipolar cells
What is the defininition of the orbit?
What can you tell me about the processing of light, how it is modified before light strikes the retina?
2. The light is focused by changes in the shape of the lens
How many tyoes of visual pigment do cones have + which one?
What are the 3 types of photoreceptor cells witthin each ommatidium + what is their nm?
2. Medium -> max sensitivity in the blue region of the spectrum -> 440 nm
3. Long -> max sensitivity in the green region of the spectrum -> 540 nm
What is the spectrum in nm in what humans can see?
What is the frequency reach in hz for humans?
From what intensity of sound can you damage the hearing receptors of the ear?
What are the 3 forms of hearing loss?
2. Central hearing loss -> results either from damage to the neutral pathways between the ear and cerebral cortex OR from damage to the cortex itself
3. Sensorineural hearing loss -> results from damage tot the structures of the inner ear
