what is truth regarding the eye development?

a- arises as extrusions from the rhombencephalon

b- arises from the interaction between lens placodes and optic cup

c- arises from the sub ectodermal branching of the first pharyngeal arch

d- first develops as the neural retina

e- all of the above

  • a. Rhombencephalon leads to the formation of medulla, the pons and cerebellum. It is hindbrain.
  • c.First pharyngeal arch gives rise to maxillary and mandibular process.
  • d. Eyes first develops as a small groove on either side of the developing forebrain. Neural retina. develops from the optic cup, a double-layered structure that is formed as an invagination of optic vesicles.

Answer is b. Arise from the interaction between lens placed and optic cup.

The uncorrected eye. For the following questions, assume that the distance between the eye lens and the retina is 1.70 cm. In other words, since the image is always formed on the retina, the distance between the lens and the image is always 1.70 cm. Also note that, as is seen in the ray diagram, since the eye lens is converging and the image is on the opposite side of the lens compared to the object, the image is always...

How is it possible that our eye allows sharp image formation from both distant and nearby objects? a. The refractive index of the cornea changes depending on how far the viewed object is. b. The shape of the lens changes between close-up and distant viewing, focusing the light on the retina. c. The muscles surrounding the eye can contract or relax, slightly changing the shape of the eye and thus allowing the incoming light to be focused on the retina...

A. The human eye 1. Whenever a normal eye forms an image, the image distance will always equal the distance from the cornea and eye lens to the retina (~25 mm), regardless of how far away the object is located. Explain why the image distance cannot change. 2. If the image distance must change, then what intrinsic property of the eye lens must change in order for the eye to focus on objects at different distances? Hint: read the Introduction....

d. During the investigation after the incident with the eye procedure, it was reported that all three women had stem cells injected into both of their eyes simultaneously. Once the women began suffering complications from the procedure, it became clear that the stem cells injected into their eyes had grown onto the retina and then contracted, detaching the retina from the optic nerve. Other than the obvious “injecting stem cells into one’s eyes” what other major flaw was made by...
