Menstrual Cycle Feedback Systems

12 Questions

Which section of the brain is responsible for the sensation of thirst?

Hypothalamus

Which of the following scenarios would occur with less insulin?

Elevated blood glucose

Which is the proper direction of impulses in the nerve system?

Motor neuron → relay neuron → sensory neuron → stimulus in response

What would be the most effective strategy to stop the ongoing degradation of our brain's synapses as we age?

Getting eight hours of sleep and exercising will prevent fast deterioration of connections.

Which part of the nervous system is responsible for the fast response of pulling your hand away from a hot burner?

Spinal column

What would occur if a competitor in athletics track and field could no longer perspire?

Overheats and easily wins the race

What stops the creation of follicle-stimulating hormone (FSH) during the menstrual cycle?

High estrogen levels

Which hormone regulates the synthesis of FSH in response to estrogen stimulation?

Luteinizing hormone (LH)

What hormone is released by the pancreas to initiate breaking down glycogen in the liver?

Insulin

Which hormone does the pancreas release to signal the liver to begin breaking down glycogen?

Glucagon

What hormone elicits more LH production due to elevated levels in the menstrual cycle?

Progesterone

What causes Angelo to seek rich foods to achieve equilibrium when his blood sugar falls below typical levels?

Adrenaline release

Study Notes

Brain Functions

The hypothalamus is in charge of the sensation of thirst.
The thalamus is not responsible for the sensation of thirst.

Insulin and Metabolism

When there is less insulin, there is elevated blood glucose and a higher rate of metabolism.
Less insulin does not result in a higher rate of carbohydrate digestion or heightened production of proteins.

Nerve Impulses

The proper direction of impulses in the nerve system is: sensory neuron → relay neuron → motor neuron → stimulus.

Synapses and Brain Health

Synapses, or connections between brain cells, are responsible for learning and thinking efficiently.
To prevent the degradation of synapses, it is effective to get eight hours of sleep and exercise, rather than consuming high-sugar and high-fat foods, staying up late, or dwelling on past errors.

Nervous System

The spinal column is responsible for the fast response of pulling your hand away from a hot burner.

Thermoregulation

Allowing excess heat to pass through the skin helps regulate body temperature.
If an athlete cannot perspire, they will overheat.

Proteins and Nucleic Acids

Amino acids are the units of proteins.
Nucleotides are the units of nucleic acids.

RNA Synthesis

RNA polymerase is the enzyme responsible for transcribing RNA from a DNA template.

Protein Synthesis

The process by which cells produce proteins is called protein synthesis.

Menstrual Cycle

The correct feedback system of the menstrual cycle is: follicle-stimulating hormone (FSH) stimulates the ovaries to release estrogen, and high estrogen levels then stop the creation of FSH.

Blood Sugar Regulation

When blood sugar falls below typical levels, the pancreas achieves equilibrium by releasing glucagon, which tells the liver to break down glycogen into a simple sugar.
