Hindbrain (Rhombencephalon)

Myelencephalon - Medulla Oblongata

Metencephalon - Pons and Cerebellum

Medulla Oblongata - Cranial nerves, hearing, visceral fibres

Pons - Fibres to cerebrum

Cerebellum - Posture, balance etc

The size of the brain differs between species, but otherwise the structure is quite constant.

-===Consequences of Cerebellar Pathology===
-* Cerebellar pathology can result in:
-*# Hypermetria
-*# Unconsious proprioceptive deficits
-*# Increased motor tone on the side of the lesion (in assymetrical damage).
-*#* This gives head tilting AWAY from the damage.
-*#** "A paradoxical vestibular sign".
-* Damage to the cerebellum does NOT cause weakness.
