Q

Fractures of the Hyoid B

Result:

How?

A

strangulation by compression of the throat.

Hyoid bone compresses Thyroid Cartilage -> difficulty swallowing and maintaining the separation of the alimentary and respiratory tracts.

Q

Why do cervical vertbrae have anterior and posterior tubercles on TP?

A

the anterior tubercle of the transverse process “would have liked to have been a rib.” This is why we have anterior and posterior tubercles
