What does the occulocephalic reflex show?
The presence of the occulocephalic reflex (doll's eye movements) in people with coma shows that the brain stem is intact.
What is an fact about the medulla oblongata?
It has the mechanisms for controlling our body's reflex activities such as coughing and vomiting
What is the function of a cartel?
to control the right side of your brain which is sort of like a controller and is looks after the brain stem.
Which part of the brain controls forceful breathing?
Ventilation occurs under the control of the autonomic nervous system from parts of the brain stem, the medulla oblongata and the pons. This area of the brain forms the respiration regulatory center, a series of interconnected brain cells within the lower and middle brain stem which coordinate respiratory movements. The sections are the pneumotaxic center, theapneustic center, and the dorsal and ventral respiratory groups. This section is especially sensitive during infancy, and the neurons can be destroyed if the infant is dropped and/or shaken violently. The result can be death due to "shaken baby syndrome".
What part of brain controls pupil dilation?
Edinger-Westphal nucleus of the brainstem controls the pupil reflex. An ER doctor who looks at the response to a pen light is checking on brain stem activity.
The micturition reflex center is located in the?
sacral segments of the spinal cord
Information from balance receptors goes directly to the?
Information from balance receptors goes directly to the brain stem reflex centers.
Which area of the brain is the main visceral control center of body?
The hypothalamus is the main visceral control center of the body and is vitally important to overall body homeostasis. Few tissues in the body escape its influence.
What does the occulocephalic reflex show?
The presence of the occulocephalic reflex (doll's eye movements) in people with coma shows that the brain stem is intact.
What is cranial reflex?
A cranial reflex is a fast, involuntary response to a stimulus. It uses the brain stem as an integrating center (the brain receives sensory information and generates a response). This is contrasted to a spinal reflex, when the response is generated in the spinal cord itself, and the brain only finds out a reflex has occurred after the fact.An example of a cranial reflex would be the tracking movements of your eyes as you are reading this sentence. The dilation and contraction of your pupils in response to different levels of light is another cranial reflex.--------------An example of a spinal reflex would be standing on a pin or touching a hot object.
Does the breathing control center in the brain monitor the rising CO2 levels in the blood?
Quite so. The brain stem detects high levels of carbon dioxide and triggers breathing.
Which portion of the human brain mediates simple reflexes such as sneezing coughing and salivating?
The medulla oblongata is a part of the brain stem involved in these reflexes. And no your eyes will not pop out if you sneeze with them open. Closing the eyes is part of the reflex and you have no control over reflexes.
Which brain region provides the signals that control the beating of the heart?
Brain stem
What is an fact about the medulla oblongata?
It has the mechanisms for controlling our body's reflex activities such as coughing and vomiting
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.
Is the brain stem responsible for the control of work of breathing?
Yes.
What is the brain-stem?
The brain stem is about the size of a thumb in diameter and approximately 3 inches (approximately 7.5 cm) long. It structures are the midbrain, pons, and the medulla obongata. The midbrain is mostly composed of tracts of nerve fibers. The midbrain has two bulging fiber tract-cerebral peduncles. It also has four rounded protrusions. The midbrain reflex centers for vision and hearing. The pons are the bulging center part of the brain stem. It is mostly composed of fiber tracts. It includes nuclei involved in the control of breathing. The medulla oblongata is the lowest part of the brain stem, it merges into the spinal cord, includes important fiber tracts, and contains important control centers. Heart rate control, blood pressure regulation, breathing, swallowing and vomiting. Recticular formation, diffus mass of gray matter along the brain stem. Involved in motor control of visceral organs. Reticular activating system plays a role in awake/ sleep cycles and consciousness
