Outer ear 

• Pinna (auricle) - visible part of the ear outside of the head.  
  
• External auditory canal 
• Ceruminous glands - specialized sudoriferous glands (sweat glands) located subcutaneously in the external auditory canal. They produce cerumen (earwax) by mixing their secretion with sebum and dead epidermal cells.

 Middle ear: air filled 

• Tympanic membrane -  vibrates in response to sound waves 
• Malleus, incus and stapes - 3 small bones that transmit vibrations to each other

Inner ear: fluid filled 

• Mechanoreceptor for hearing and balance 
  
• Vesibular apparatus - balance
  
• Semicircular canals 
  
• Cochlea
•  • Organ of Cor -  sensory epithelial cell
  

Cochlea

• Perilymph = similar in compositon to plasma – Na+ 
  
• Endolymph = high in K+ 
  
• Organ of Cor: contains hair cells – move due to pressure waves 
  
• 50-100 stereocilia on each cell 
  
• Longest embedded in tectorial membrane 
  

In the cochlea that the vibrations transmitted from the eardrum through the tiny bones are converted into electrical impulses sent along the auditory nerve to the brain. 

• The cochlea is a tapered tube which circles around itself 
• The basilar membrane divides the tube lengthwise into two fluid-filled canals joined at the tapered end. 
• ossicles transmit vibration to the cochlea where they attach at the oval window
• resultant waves travel down the basilar membrane where they are “sensed” by  16-20,000 hair cells (cilia) attached to it which poke up from a third canal called the organ of Corti. 
• Organ of Corti transforms the stimulated hair cells into nerve impulses 
• Waveforms travelling down the basilar membrane peak in amplitude at differing spots along the way according to their frequency 
• Higher frequencies peak out at a shorter distance down the tube than lower frequencies
• The hair cells at that peak point give a sense of that particular frequency
• The distance between pitches follows the same logarithmic distance as our perception of pitch i.e. the placement of octaves are equidistant.
  

Anatomía del oído.

Es en el único lugar donde contamos con un ombligo. ( específicamente en la membrana timpánica)

El que conocemos comúnmente como ombligo ( en nuestro abdomen ) es realmente llamado como “cicatriz umbilical”.

uni-med:

 Hirschsprung’s disease is a condition that affects the large intestine (colon) and causes problems with passing stool.

While this condition is almost always congenital where in there is absence of nerve plexuses in the intestine.

Image source: My Health Alberta.

There is only one acquired condition that is known to cause this and that is Chagas disease caused due to infection by T. cruzi parasite.

Megacolon congénito

Causado por una falta de migración de las células de la cresta neural.

Lo cual provoca una ausencia de ganglios parasimpaticos cuyos mandan la sensación de defecar.
