Pons


SITUATION

The brainstem is the lower tapering end of the brain which continues downwards as spinal cord.  Pons is situated ventral (in front) to the cerebellum, packed between medulla and midbrain.

 

STRUCTURE

Pons is about 2.5 cm in length in humans. It is mostly a big bulge directed anteriorly (in front). Posteriorly it is mainly in the form of a stalk like structure, cerebellar peduncles, connecting cerebellum with pons and midbrain.

 

FUNCTIONS

Pons is considered to work with cerebellum and other brain structures. It is implied that it has a role in sleep, taste, eye movement, facial expression, swallowing, respiration and other functions of brainstem.

 

ASSOCIATED PATHOLOGY

A demyelinating disease called the central pontine myelinolysis associated with difficulty in swallowing, walking, sense of balance and touch. In severe cases it may cause death.
