Study group discussion: 45 centimetres in length and tubes

What are structures in our body about 45 cms in length?

That's an odd question. As in why do we need to know / significance?

Just to remember! Examiner here asked us in viva.

The spinal cord, Umbilical cord, Femur, Thoracic duct.

I know the esophagus is 25 cm in length. And the length from the incisor is longer. Were you given a nasogastric tube in your viva?


Nasogastric tube 104 cm I guess..?

Varies 105 cms or 75 cms Ryle's.

This is gonna sound really basic but umm.. Can anyone explain the difference between an infant feeding tube, nasogastric tube and a Ryles tube?

Ryles tube is nothing but nasogastric tube.. Used for both diagnostic and therapeutic purposes.

Ohh.. I thought nasogastric and Ryle's are different.

In infant feeding tube there are no lead shots like in Ryle's tube.. And it's 52 cm in length.

Infant tube is narrow.

Infant feeding tube is used in: Tracheoesophageal fistula
Choanal atresia
Imperforate anus
Upper GI bleed
