Why does alcohol work so fast?
Alcohol is a drug that enters the bloodstream without being broken down in the stomach by the digestive system. Therefore alcohol gets to the brain quickly (unless there is enough food in the stomach to slow it down). When an alcoholic beverage is swallowed, it is diluted by gastric juices in the stomach. A small portion of the alcohol is diffused into the bloodstream directly from the stomach wall, but most passes through the pyloric junction into the small intestine, where it is very rapidly absorbed. However, up to half the alcohol is degraded in the stomach before it passes into the small intestine. In general, a lower percentage of the alcohol is degraded in a young woman's stomach than in a young man's because a young woman's gastric secretions contain lower levels of the enzyme alcohol dehydrogenase (ADH), which breaks down alcohol prior to absorption. The rate at which alcohol is absorbed can be affected by a number of factors. For example, a strong alcoholic drink, when taken into an empty stomach, may cause a spasm of the pylorus that will impede passage into the small intestine, resulting in a slower overall rate of absorption. The presence of food in the stomach, especially some fatty foods, will also delay absorption. Naturally carbonated alcohol such as champagne or alcohol taken with a carbonated beverage such as soda water will ordinarily be absorbed more rapidly than noncarbonated alcohol. Other factors, such as the emotional state of the drinker, may also affect the rate of absorption. *just a reminder that the amount of alcohol degraded in the stomach via gastric ADH is usually lower than the main organ of degradation via ADH, the liver. Gastric ADH is found within the stomach cells and not in gastric secretions. So ADH in fact mostly breaks down alcohol AFTER it's been absorbed, not before*
Does the cerebellum controls the heart rate?
No. The medulla controls heart rate, along with breathing and digestion.
What neural structure can be seen in a mid sagittal view of the human brain?
That structure is called as falx cerebri. You have superior sagittal sinus above and inferior sagittal sinus running below the same.
Which side do you wear a blazer badge left or right?
left whilst you are wearing the garment. If you face the jacket it 'appears' to be on the right, but sew it on the left that is also where you will find the pocket put there there by the tailor
Which area of the brain controls the heart rate digestion and breathing?
the brain stem is what controlls the heart rate, respiration and such.
Where is acromagaly tumor found in the brain?
Acromegaly is typically caused by a benign tumor in the pituitary gland of the brain. This tumor leads to the overproduction of growth hormone, resulting in symptoms such as abnormal growth of bones and tissues.
What is the difference between human and goat brain?
Human brain is well developed as compared to goat brain.
Does a split brain person have a severed cerebellum?
They could, but they don't (most usually -- in fact, I've never heard of it).
Can people live without a pineal gland?
Yes, people can live without a pineal gland. They will be able to have normal lives.

Reflex buying means the buying of products on which we have been pre-sold through advertising.
Why thalamus is called the gateway of cerebral cortex?
Every part of the brain that communicates with the cerebral cortex must relay its signals through a nucleus of the thalamus.
How is your brain like a high school basketball team?
All the parts have to work together to be successful. If one part of the brain is damaged it's going to cause problems, just like if one member of the team is missing or underperforming the whole team suffers.
What is another name for the frontal lobe?
the cerebrum As far as im awarethere is no other name for it. The cerebrum however is deffinetly not it, this term refers to all the lobes of the brain (frontal, occipital, parietal and temporal)
What is the main job of the medulla?
The main job of the medulla, specifically the medulla oblongata, is to regulate vital autonomic functions, such as breathing, heart rate, and blood pressure. It serves as a critical pathway for communication between the brain and spinal cord. Additionally, the medulla controls reflex actions like swallowing, coughing, and vomiting. Overall, it plays a crucial role in maintaining homeostasis in the body.
