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 area of the brainstem controls salivation?
Salivation is controlled by the salivatory nuclei located in the medulla oblongata region of the brainstem. These nuclei receive input from higher brain centers as well as sensory information to regulate the production of saliva.
What part of the brain is affected in decerebrate?
Decerebrate rigidity primarily results from damage to the brainstem, specifically the midbrain and upper pons. This condition occurs when the brain is separated from the higher centers of the brain, particularly the cortex and basal ganglia, leading to an imbalance in motor control. The loss of inhibitory input from the brain's higher centers causes excessive extensor muscle tone, resulting in the characteristic posture associated with decerebrate rigidity.
What lobe of the cerebrum are the association centers for hearing and smelling located?
The association centers for hearing are located in the temporal lobe, specifically in an area called the auditory cortex. The association centers for smelling, on the other hand, are located in the olfactory bulb and olfactory cortex, which are part of the frontal and temporal lobes.
Can the autonomic interating centers be influenced by higher brain area?
No, the autonomic nervous system controls smooth muscle, such as organs and some glands.
What does the brain term higher centers refer to?
Higher centers refer to regions of the brain that are involved in higher cognitive functions such as decision-making, problem-solving, and emotional regulation. These areas are typically located in the cerebral cortex and are responsible for integrating information from different brain regions to carry out complex tasks.
What is the section of the brain located at the rear and bottom of the each cerebral hemisphere and contains the visual centers of the brain?
d
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.
Where are the respiratory control centers located in the brain?
The respiratory control centers in the brain are primarily located in the medulla oblongata and pons, which are part of the brainstem. These regions regulate the rate and depth of breathing to maintain appropriate levels of oxygen and carbon dioxide in the body.
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 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 area of the brainstem controls salivation?
Salivation is controlled by the salivatory nuclei located in the medulla oblongata region of the brainstem. These nuclei receive input from higher brain centers as well as sensory information to regulate the production of saliva.
The is a conduction pathway between higher and lower brain centers and houses nuclei for cranial nerves V-VII?
pons
Is it true or false that the messages involved inautomatic reflexes are coordinated by reflex centers in the brain?
False. Reflex actions are typically coordinated by reflex arcs involving the spinal cord rather than reflex centers in the brain. The spinal cord can process and respond to certain stimuli without involving higher brain centers, allowing for quick and automatic responses.
What part of the brain is affected in decerebrate?
Decerebrate rigidity primarily results from damage to the brainstem, specifically the midbrain and upper pons. This condition occurs when the brain is separated from the higher centers of the brain, particularly the cortex and basal ganglia, leading to an imbalance in motor control. The loss of inhibitory input from the brain's higher centers causes excessive extensor muscle tone, resulting in the characteristic posture associated with decerebrate rigidity.
Where is the Breathing rate controlled?
The breathing rate is primarily controlled by the respiratory centers located in the brainstem, specifically in the medulla oblongata and the pons. These centers regulate the rhythm and depth of breathing by responding to various chemical signals, such as levels of carbon dioxide and oxygen in the blood. Additionally, higher brain centers can influence breathing patterns based on emotional states or voluntary control.
Do both animals and humans have reward centers in the brain?
Both animals and humans do have reward centers in the brain. Both humans and animals feel happy or pleasure when the reward centers of the brain are stimulated.
