Explanation:
The floor of the orbit is the structure involved in the fracture by Reventon. On both sides of the face at the level of the midline we find the orbital cavities responsible for housing the eyeballs and their annexes. The zygomatic bone is part of the orbit floor. With orbital floor fractures, the prolapse of the orbital fat in the maxillary sinus can be considerable and the lower rectus muscle is equally compromised.

Explanation:
The oncotic pressure inside the cell will be greater than the pressure outside. Thus causing the cell membrane to rupture. If red blood cells are placed in pure water, water enters into the red blood cells by osmosis and the red blood cells swell up and burst while the onion cells would absorb water due to osmosis, swell and become turgid.The cell sap move conc. than surrounding water gate into the cell by osmosis; the cell swells/becomes turgid; but does not burst due to the cell wall.
The scientific method or scientific analysis can be defined as the objective search for the truth. When a scientist does an experiment, it is essential that he reports every observation in the result, whether it is in uniformity with the experiment or not. Many scientific discoveries are made based on the unusual findings. The failure to report these unusual findings during an experiment might result in the loss of vital information.
If light strikes one receptor, the net effect is to excite the nearest bipolar cell and inhibit other bipolar cells to the side because of the contributions from horizontal cells.
<u>Explanation:</u>
On striking the receptor with light, the nearest bipolar cells respond to the light at the most inside the circumference. The bipolar cells which are outside the circumference responds least to the phenomena. Overall, the net effect thereby when seen, is to excite the nearest bipolar cells.
By the excitement of nearest bipolar cells, other farther cells are inhibited as a result as the horizontal cells are also excited and they contribute to inhibit the bipolar cells which are not near to the receptor cells in the eyes.
