Involuntary control of muscle tone and posture
|
|
|
MEDULLA - Nucleus gracilis
|
Relay somatic sensory information from the lower body to the ventral posterior nuclei of the thalamus
|
|

|
|
|
MEDULLA - Ascending and Descending Tracts
|
Link the brain with the spinal cord
|
|
|
CEREBELLUM - Superior Peduncle
|
Link the cerebellum with the midbrain, the diencephalons and cerebrum
|
|
|
MIDBRAIN - Substantia Nigra
|
Regulates activity in the cerebral nucleus

|
|
MEDULLA - Other nuclei/centres
|
Sensory and motor nuclei of CN VIII, IX, X, XI, XII
Nuclei relaying ascending sensory information from the spinal cord to higher centres |

MEDULLA - Nucleus cuneatus
|
Relay somatic sensory information from the upper body to the ventral posterior nuclei of the thalamus
|
|
|
MIDBRAIN - Superior Colliculus
|
Integrates visual information with other sensory inputs; initiates involuntary motor responses
