Antonio Margarito's Orbital Fracture: General Anatomy for Boxing Fans

Note: I wrote this on my Facebook page as a note.
___________________________________

The general anatomy teacher in me can't help but explain about the orbital fracture of boxer Antonio Margarito. 
ARLINGTON, TX - NOVEMBER 13: A detail of the cut on the right eye of Antonio Margarito (black trunks) of Mexico is seen as he fights against Manny Pacquiao (white trunks) of the Philippines during their WBC World Super Welterweight Title bout at Cowboys Stadium on November 13, 2010 in Arlington, Texas.

The orbit is the bony structure surrounding the eyeball. According to the Medterms Medical Dictionary (at http://medterms.com/ ), the orbit is: "in medicine, the bony cavity in which the eyeball sits together with its associated muscles, blood vessels, and nerves. The orbit is formed of parts of the ethmoid, frontal, lacrimal, nasal, palatine, sphenoid, and zygomatic bones and the maxilla." These are names of bones of the skull and they all have processes, or extensions, which form part of the bony walls of the orbit, save for the lacrimal bone which is only found in the orbit and is not an extension of another bone.

Technically, there is no anatomic structure named an "orbital bone", because these bones are all part of the orbit. It may have been better said as " Antonio Margarito suffered a fracture of one of the bones of the orbit." But that's just a perfectionist anatomy teacher's opinion. The drawing below, from a website called ophthobook.com, shows the different bones which are part of the orbit. To orient yourself, the right of the drawing is the middle part of the face, where the nose is. The left of the drawing is toward the cheek or the side of the face. If one looks at Antonio Margarito's injury in the first picture, he probably had a fracture of the zygomatic bone or the orbital process (process=a bony extension) of the maxillary bone, or both. 

So his doctor made a good call to send Antonio Margarito straight to the hospital after the fight. This fracture is a medical emergency indeed.

A Mulberry Molar and A Mulberry...and A Custard Apple

The mulberry molar of congenital syphilis:



Looks like the mulberry fruit:

But I think that the mulberry molar looks like the custard apple fruit ("atis"), a fruit found in the Philippines. Mulberries are very rare here unlike the custard apple. As for me, we should call the mulberry molar an "atis" molar in the Philippines.



custard apple or "atis"

Pic of Tuberculous Lung with Caseation Necrosis


Caseation necrosis occurs in pulmonary tuberculosis. It's called caseation necrosis after "casein", a protein found in cheese, because the caseation looks like soft cheese. (See the oval-shaped yellowish-stuff filled cavity on the top of the lung specimen shown above.)

This is a pic of soft cheese from a cheese-making store in the UK:
See the resemblance?

:-P
