Which structure links the upper and lower centers of the brain?
The brainstem is the structure that links the upper and lower centers of the brain. It connects the cerebrum (upper brain) to the spinal cord (lower brain) and is responsible for basic life functions such as breathing, heartbeat, and blood pressure regulation.
What is a conduction pathway between higher and lower brain centers and houses nuclei for cranial nerves 5-7?
The pons serves as the conduction pathway between higher and lower brain centers. It also contains nuclei for cranial nerves 5 (trigeminal), 6 (abducens), and 7 (facial).
What lower part of the brain contains centers more vital to life?
The lower part of the brain that contains centers more vital to life is the brainstem. It includes important structures such as the medulla oblongata, which controls essential functions like breathing, heart rate, and blood pressure. Additionally, the brainstem controls other vital activities such as swallowing, digestion, and body temperature regulation.
Which structure is the lower portion of the brainstem?
Medulla OblongataThe medulla oblongata is the most inferior portion of the brain, and it is the connecting link with the spinal cord.
What are the ascending fibres of projection fibres?
They are fibres which radiate from thalamus and metathalamus to the cerebral cortex. They include:Anterior thalamic radiationsuperior thalamic (sensory) radiationposterior thalamic radiation, which consists of = optic + auditory radiations
Which structure links the upper and lower centers of the brain?

What contains reflex centers involved in regulation respiratory rhythm in conjunction with lower brain stem centers?
The medulla oblongata, located in the brain stem, contains reflex centers that are involved in regulating the respiratory rhythm in conjunction with other lower brain stem centers. These centers help coordinate the muscles involved in breathing to ensure proper oxygen intake and carbon dioxide removal.
What is the lower brain structure that govern arousal?
Medulla
What Part of the brain responsible for licking and eating reflexes?
The part of the brain responsible for eating are appetite centers of the amygdala and hypothalamus. The licking reflex is seen only certain animals but the centers are located in the medulla oblongata in the lower brainstem.
What is a conduction pathway between higher and lower brain centers and houses nuclei for cranial nerves 5-7?
The pons serves as the conduction pathway between higher and lower brain centers. It also contains nuclei for cranial nerves 5 (trigeminal), 6 (abducens), and 7 (facial).
The is a conduction pathway between higher and lower brain centers and houses nuclei for cranial nerves V-VII?
pons

The lower part of the brain that contains centers more vital to life is the brainstem. It includes important structures such as the medulla oblongata, which controls essential functions like breathing, heart rate, and blood pressure. Additionally, the brainstem controls other vital activities such as swallowing, digestion, and body temperature regulation.
What does the word 'relayed' describe in a medical context?
The medical dictionary does not have a definition for the word relayed. The closest word to it is a 'relay nucleus' which is a part of the brain that relays stimuli from the lower receptor centers to matching cortical centers.
What is the the lower brain that controls and coordinates fine motor movement?
The cerebellum is the lower brain structure responsible for controlling and coordinating fine motor movements. It helps to maintain posture, balance, and smooth execution of voluntary movements.
What contains reflex centers involved in regulating respiratory rhythm in conjunction with lower brainstem centers?
The medulla oblongata is responsible for breathing as well as heart rate. It is located in the lower half of the brainstem, and is considered to be one of the oldest (earliest developed) brain areas. It is unconsciously controlled.
What part of the brain is responsible for eating and licking reflexes?
The part of the brain responsible for eating are appetite centers of the amygdala and hypothalamus. The licking reflex is seen only certain animals but the centers are located in the medulla oblongata in the lower brainstem.
What part of the nervous system is not involved in producing reflex actions?
The cerebral cortex is not directly involved in producing reflex actions. Reflex actions are controlled at the spinal cord or lower levels of the brain without involvement of higher brain centers like the cerebral cortex.
