Answer:
Sleep deprivation can cause the body to react as if it is in distress, releasing more cortisol, the stress hormone. Cortisol is the hormone that triggers your fight or flight response in the face of danger, raising your heart rate in preparation for a fight. Sleep disruptions can further disrupt your HPA axis, causing cortisol production to be distorted. Insomnia and other forms of sleep loss have been shown to cause your body to generate extra cortisol during the day, maybe to boost alertness.
Explanation:
The body's natural stress reaction kicks in during times of tension, starting with a cascade of hormones that make us feel more alert and cause subsequent physiological changes.
Answer:
This is synaptic pruning- it removes them
Explanation:
The gaps and the portions of neurons between adjacent neurons is called synapse.It role is to moderate synaptic connections among neurons.
As organisms (man and other higher animals)develop from birth to adult,new synaptic connections are formed,and old ones are removed.The process whereby the the axon and dendrite, as part of the synapse, decay and removed by the brain is called synaptic pruning or pruning process.
This process begins at childhood and continue till maturity- at mid twenties.it occurs during sleep.
it helps to improve learning and memory,because new connections are made to replace the old ones,and therefore smooth transition of the brain from childhood to adulthood
Three models have been used to explain pruning-Axon degeneration,retraction and Axon shedding.
Answer:
0.4 ml
Explanation:
The mother solution contains 10 mCi, but the patient just need 4 mCi.
So using a rule of three, it would be:
10 mCi - 1 ml
4 mCi - X X = (4x1) /10 = 0.4 ml
And considering the half life of 6 hours, need to pass 18 h to have a dose in the body that is insignificant. (at the first 6 h it will have 2 mCi, at the next 6 hours 1mCi, at the next 6 hours 0.5 mCi)
So it would be 0.4 ml of the mother solution every 18 h.
