Stimulation of the adrenal medulla leads to the release of catecholamines, primarily adrenaline (epinephrine) and norepinephrine, into the bloodstream. This response prepares the body for a "fight or flight" reaction, resulting in increased heart rate, elevated blood pressure, enhanced blood flow to muscles, and heightened alertness. Additionally, it may cause the release of glucose for energy and a decrease in digestive activity. Overall, these effects help the body respond to stress or danger.
What else can I help you with?
What would a rise in angiotensin II levels would result in?
A rise in angiotensin II levels can lead to vasoconstriction, increased blood pressure, and stimulation of the release of aldosterone from the adrenal glands, which increases sodium and water reabsorption in the kidneys. Ultimately, this can contribute to hypertension and increased fluid retention in the body.
What would happen if your medulla was removed?
I'm not sure if it's possible for you to technically break your medulla oblongata, but damage to that part of the lower portion of your brainstem could make it difficult for you to live...at least comfortably. I say this because the medulla oblongata is responsible, primarily, for controlling one's heart rate, among other autonomic functions (meaning functions that are formed involuntarily and without your conscious control). Other functions that would be affected by a medulla oblongata that was damaged would include one's respiration, reflexes, defecation, blood pressure, swallowing, etc, as the nerve signals between the brain and spinal cord would no longer be working.
What doctor would you see for adrenal gland?
To address issues related to the adrenal glands, you would typically see an endocrinologist. This specialist focuses on hormonal disorders and can diagnose and treat conditions affecting the adrenal glands, such as Addison's disease or Cushing's syndrome. In some cases, your primary care physician may also provide initial evaluation and referrals to an endocrinologist if necessary.
Damage to the renal medulla would interfere first with the functioning of what?
Damage to the renal medulla would first interfere with the concentration of urine, as this is where the final processing occurs to regulate the concentration and volume of urine produced by the kidneys. Additionally, it would affect the regulation of blood pressure through the renin-angiotensin-aldosterone system which is crucial for maintaining blood pressure homeostasis.
Which endocrine organs would you expect to be relatively larger in humans than cats?
The pituitary and thyroid glands are typically larger in humans compared to cats due to differences in hormone regulation and metabolic rates. Human adrenal glands are also relatively larger as they are essential for stress response and regulation in humans.
What is an Abnormal increase of epinephrine?
There are numerous causes, but one of the most "abnormal" would be a pheochromocytoma a neuroendocrine tumor of the medulla of the adrenal gland. That part of the adrenal gland is responsible for producing epinephrine, and the tumor often releases large amounts of epinephrine into the blood.
What are the side effects of having a adrenal gland tumor removed?
You may injure your adrenal glands which could cause you to have signs of fatigue. It would be best to supplement with raw adrenal in this case.
Increased vagal stimulation would cause?
Increased vagal stimulation would cause a decrease in heart rate and blood pressure. The vagus nerve is part of the parasympathetic nervous system, which promotes relaxation and slows down physiological processes.
What does nodular thickening of the adrenal glands mean?
Nodular thickening of the adrenal gland means that cancer could be present. It would normally be treated by surgical removal of cancerous tumors.
Where would you find the medulla oblongata?
medulla oblongata is situated in the brain
Stimulation of which would cause an increase in heart rate and contraction strength?
beta 1 receptors
What would Direct stimulation of the motor cortex result in?
It would cause involuntary movement or a sense of touch on the person.
What are symptoms of damage to the medulla oblongata?
Symptoms of damage to the medulla oblongata is that the nerve signals between the spinal cord and the brain would no longer be working. The medulla helps to control vital functions of the brain such as breathing, blood pressure and regulating heart rate.
What would life be without adrenal glands?
Life would be nothing there's really nothing life would be without adrenal glands because really god created people such as( life) so to me i think life would live without adrenal glands;
On which of these organs would the adrenal glands be located?
The adrenal glands are located on top of the kidneys.
What is an auditory stimalation?
Auditory stimulation is stimulation by sound. An example would be your reaction to someone sneaking up behind you and loudly clapping their hands. The stimulation would be the sound. Your reaction would probably be to become startled or jump.
Damage to which of these areas would most likely cause death optic chiasm medulla temporal cortex or prefrontal cortex?
Assuming the damage did not involve an infection, the medulla. The medulla controls autonomic functions like respiration and blood pressure, which you do not consciously control. As these functions are vital to staying alive, losing function of the medulla would most likely cause death. Damage to the optic chiasm could cause full or partial blindness, depending on the location of the damage. Damage to the temporal cortex could result in impairments in object perception as well as memory. Damage to the prefrontal cortex could result in impairments of executive functions, some examples of which include working memory (holding an item, like a phone number, in mind), decision making, and problem solving.
