Brainstem consists of... |
Mid brain, pons and medulla oblongata |
|
|
|
Function of the brainstem |
-Provides pathways for nerves. -Houses 10 of 12 pairs of cranial nerves. -Looks after all body's basic body functions. -3 areas together programme autonomic behaviours. |

|
Mid brain |
-3 sections to mid brain. - 1) Pain and pain suppression. - 2) Coordinates eye and head movements by linking visual and auditory together. - 3) High melanin content, precursor of dopamine. |

|
Dopamine function |
Supports basal ganglia. Basal ganglia will not function properly without dopamine. No/reduced dopamine = parkinson's disease. |
|
|
|
Function of the pons |
-Cerebellum grows out of pons. -communicates with the Cerebellum. -PNEUMOTAXIC CENTRE |
|
|
|
PNEUMOTAXIC centre |
-Within the PONS -works with MEDULLA OBLONGATA to maintain normal breathing. |
|
|
|
Medulla oblongata |
- Where nerves cross over (decussate) - also communicates with cerebellum. -CARDIOVASCULAR, VASOMOTOR and RESPIRATORY CENTRES located here. |
|
|
|
CARDIOVASCULAR CENTRE |
within medulla oblongata Regulates force and rate of the heart |
|
|
|
VASOMOTOR CENTRE |
-Within medulla oblongata -regulates vessel diameter to regulate BP. |
|
|
|
RESPIRATORY CENTRE |
-Within medulla oblongata -works with pons to regulate rate and depth of breathing. |
