Can difficulty breathing reflect damage respiratory centers located?
The parasympathetic and sympathetic nervous systems are subdivisions of the autonomic nervous system. Difficulty in breathing may reflect damage to respiratory centers located in the cerebellum. A sensory neuron carries stimuli from the central nervous system to the effector.
What brain dysfunction results when blood supply to a region or regions of the brain is blocked and vital brain tissue dies as by a blood clot or a ruptured blood vessel?
A stroke occurs when an artery to the brain becomes blocked or ruptures, resulting in death of an area of brain tissue due to loss of its blood supply (cerebral infarction) and symptoms that occur suddenly.
What part of the brain stem House reflex centers for vision and hearing?
The midbrain (mesencephalon) is associated with vision, hearing, motor control, sleep and wake cycles, alertness, and temperature regulation.
How does the brain communicate with the respiratory system?
The carotid body communicates with medullary respiratory neurons through sensory fibres that travel with the carotid sinus nerve, a branch of the glossopharyngeal nerve.
Which nerve is responsible for breathing?
The phrenic nerve controls the diaphragm, which is the major muscle for breathing. Three major nerves (given the symbols C3, C4, C5) exit from the spinal cord in the neck and combine to form the phrenic nerve.
What brain dysfunction results when blood supply to a region or regions of the brain is blocked?
What happens when blood does not reach the brain?
If damage occurs to a blood vessel in the brain, it will not be able to deliver enough or any blood to the area of the brain that it serves. The lack of blood interferes with the delivery of adequate oxygen, and, without oxygen, brain cells will start to die. Brain damage is irreversible.
What controls heartbeat and breathing in the brain?
Medulla. At the bottom of the brainstem, the medulla is where the brain meets the spinal cord. The medulla is essential to survival. Functions of the medulla regulate many bodily activities, including heart rhythm, breathing, blood flow, and oxygen and carbon dioxide levels.
