The Brain - 9.2 - The Brainstem Flashcards
The ascending tracts of the spinal cord continue into the part of the brain called the:
Brainstem
The descending tracts of the brainstem next travel into the:
Spinal Cord
Name the three parts of the brainstem.
- Midbrain
- Pons
- Medulla oblongata
Arrange the following in order from superior to inferior. Medulla oblongata, Midbrain, Pons
Midbrain, Pons, Medulla oblongata
Where does the brainstem connect to the spinal cord?
At the foramen magnum
A stroke is more likely to be fatal if it occurs in the ________________ part of the brain.
Brainstem
What three vital centers are found in the medulla oblongata?
- Cardiac center
- Respiratory center
- Vasomotor center
The cardiac center of the medulla oblongata receives input and controls (regulates):
Heart rate and strength of contraction
The respiratory center of the medulla oblongata receives input and controls (regulates):
Breathing Rate & depth
What spinal nerve is associated with the diaphragm muscle that causes breathing?
The Phrenic Nerve
The respiratory center of the medulla oblongata regulates the breathing rate via what spinal nerve?
The Phrenic Nerve
The vasomotor center of the medulla oblongata receives input and controls (regulates):
Blood Pressure (Vaso means blood vessel)
What is the “relay station” for nerve signals going to the cerebellum from the cerebrum?
Pons
Auditory and Vision reflexes are found in what brainstem structure?
Midbrain
The inferior and superior colliculi are located on the:
Midbrain
