Your not getting anough sugar

increased blood glucose (hyperglycemia), decreased blood glucose (hypoglycemia), increased glucose in the urine (glycosuria), and decreased glucose in CSF, serous, and synovial fluid glucose.
Muscle requires glucose, and so there is not the same concentration of glucose in blood entering and exiting a muscle. The exiting blood will be lower in glucose.
Yes
This process is known as glycogenolysis, where stored glycogen in the liver is broken down into glucose and released into the blood to maintain blood glucose levels.
Insulin causes a decrease in the concentration of blood glucose by promoting the uptake of glucose into cells, especially muscle and adipose tissue. It also stimulates the storage of glucose as glycogen in the liver and muscle.
Regulating blood glucose concentration
glucagon
i know it's higher than corresponding blood glucose concentration from 10 - 15%
The concentration of glucose is typically higher in plasma (blood) compared to cerebrospinal fluid because glucose is actively transported from blood into the brain. Normal CSF glucose levels are around 60-70% of plasma glucose levels.
Glucose concentration can affect active transport by influencing the rate of transport. In some cases, a higher glucose concentration can lead to an increased rate of active transport to maintain cellular homeostasis. Conversely, a lower glucose concentration may result in decreased active transport activity until a balance is restored.
