Identify the 3 structures that compose the brainstem and their basic functions
|
Pons: respiratory center
Midbrain: nerve pathway of the cerebral hemispheres Medulla: relay station for the crossing of motor tracts between the spinal cord and the brain. |
|
|
Where is the respiratory center located?
|
Pons; houses the pneumotaxic and apneustic areas.
|
|
|
What are the 2 components of the respiratory center?
|
Signals for voluntary movement originate in the cerebral cortex and are relayed through the pons via the pontine nuclei to the cerebellum.
|
|
|
The functions of the brainstem:
|
Neurological functions for survival such as breathing, digestion, heart rate and blood pressure and arousal.
|
|
|
The midbrain:
|
Is seated between the pons and diencephalon
|
|
|
Cranial nerves III and IV are found in the...
|
Midbrain
|
|
|
The basilar and anterior, inferior, and superior cerebellar arteries are found in the:
|
Pons
|
|
|
The pons:
|
1 -Is a bridge-like structure where bundles of axons link different parts of the brain
2 Is a relay station from the medulla to the higher cortical structures of the brain |
|
|
What area of the brainstem do motor tracts cross between the spinal cord and the brain?
|
Medulla oblongata
|
|
|
The medulla oblongata contains:
|
a. White and gray matter
b. Olive/inferior olivary nucleus c. Gracile and cuneate nucleus |
|
|
T/F: The Reticular Activating System is the area that maintains consciousness.
