Brainstem Flashcards
(24 cards)
What are the three main divisions of the brainstem?
The medulla oblongata, the pons, and the midbrain.
Which division of the brainstem is responsible for controlling vital functions like breathing and heart rate?
The medulla oblongata.
What is the primary function of the pons in the brainstem?
To serve as a bridge between different parts of the brain.
Which division of the brainstem is located between the medulla oblongata and the midbrain?
The pons.
What is the main function of the midbrain in the brainstem?
To control eye movement and relay visual and auditory information.
True or False: The brainstem is responsible for higher brain functions like conscious thought and decision-making.
False.
Which part of the brainstem is continuous with the spinal cord?
The medulla oblongata.
What is the reticular formation in the brainstem responsible for?
Regulating sleep-wake cycles and consciousness.
What is the function of the tectum in the midbrain?
To control reflexive movements in response to visual and auditory stimuli.
Which division of the brainstem is responsible for maintaining balance and coordination?
The cerebellum.
What is the main function of the red nucleus in the midbrain?
To control voluntary movements.
Which part of the brainstem is responsible for processing sensory information and coordinating motor responses?
The midbrain.
What is the function of the substantia nigra in the midbrain?
To regulate reward and movement.
True or False: Damage to the brainstem can result in paralysis.
True.
Which division of the brainstem is responsible for transmitting information between the spinal cord and higher brain structures?
The pons.
What is the main function of the inferior colliculi in the midbrain?
To process auditory information.
Which division of the brainstem contains the nuclei responsible for cranial nerves III to XII?
The midbrain.
What is the function of the medulla oblongata in the brainstem?
To regulate essential autonomic functions like heart rate and blood pressure.
True or False: The brainstem plays a role in controlling emotions and memory.
False.
Which part of the brainstem is responsible for the fight-or-flight response?
The reticular formation.
What is the function of the superior colliculi in the midbrain?
To process visual information and control eye movements.
Which division of the brainstem contains the nuclei responsible for cranial nerves V to VIII?
The pons.
What is the main function of the cerebral peduncles in the midbrain?
To connect the cerebral cortex to the rest of the brain.
True or False: The brainstem is essential for survival as it controls basic life-sustaining functions.
True.
