Essential Interview Questions For Physiology Teacher
1. Explain the role of the autonomic nervous system in regulating heart rate?
The autonomic nervous system (ANS) plays a crucial role in regulating heart rate by coordinating the opposing actions of the sympathetic and parasympathetic divisions:
- Sympathetic division: Releases norepinephrine, which increases heart rate by stimulating beta-adrenergic receptors on the heart.
- Parasympathetic division: Releases acetylcholine, which decreases heart rate by stimulating muscarinic receptors on the heart’s sinoatrial node.
2. Describe the mechanisms involved in blood pressure regulation.
Control of Peripheral Resistance
- Sympathetic innervation of arterioles: Sympathetic nerve activity causes vasoconstriction, increasing peripheral resistance and blood pressure.
- Local factors: Tissue metabolites, such as adenosine and nitric oxide, can cause vasodilation or vasoconstriction, influencing local blood flow and overall resistance.
Control of Cardiac Output
- Regulation of heart rate: As discussed in Question 1, the ANS modulates heart rate, which directly affects cardiac output.
- Regulation of stroke volume: Stroke volume is influenced by factors such as muscle contractility, preload, and afterload, all of which can be regulated by hormones and the nervous system.
Volume Regulation
- Renin-angiotensin-aldosterone system: This hormonal pathway promotes fluid retention and vasoconstriction.
- Antidiuretic hormone (ADH): ADH released by the pituitary gland increases water reabsorption in the kidneys, conserving blood volume.
3. Discuss the factors that affect glomerular filtration rate (GFR).
Glomerular filtration rate (GFR) is influenced by several factors:
- Glomerular capillary pressure: Increased pressure in the glomerular capillaries promotes filtration.
- Bowman’s capsule pressure: Increased pressure within Bowman’s capsule opposes filtration.
- Surface area of the glomerular capillaries: A larger surface area allows for more filtration.
- Permeability of the glomerular capillaries: Increased permeability facilitates filtration.
- Renal autoregulation: Mechanisms such as myogenic response and tubuloglomerular feedback help maintain a relatively constant GFR despite changes in blood pressure.
4. Explain the process of gas exchange in the lungs.
Gas exchange in the lungs occurs through a series of steps:
- Ventilation: Inhalation brings air into the lungs, filling alveoli with oxygen-rich air.
- Diffusion: Oxygen from the alveoli diffuses across the alveolar-capillary membrane into the pulmonary capillaries.
- Hemoglobin binding: Oxygen molecules bind to hemoglobin within red blood cells.
- Transport: Oxygen-rich blood is transported throughout the body by the circulatory system.
5. Describe the mechanisms that regulate body temperature.
Body temperature is regulated through several mechanisms:
- Thermoreceptors: Thermoreceptors in the skin, hypothalamus, and spinal cord detect changes in temperature.
- Hypothalamus: The hypothalamus integrates information from thermoreceptors and acts as a thermostat, comparing actual body temperature to a set point.
- Heat production: When body temperature falls, mechanisms such as shivering and increased metabolic activity generate heat.
- Heat loss: When body temperature rises, mechanisms such as sweating, vasodilation, and increased respiratory rate promote heat loss.
6. Explain the concept of action potential and its propagation along a neuron.
An action potential is a brief electrical impulse that propagates along a neuron’s membrane:
- Resting potential: Neurons maintain a polarized state with a negative charge inside the membrane.
- Depolarization: Stimuli cause sodium channels to open, allowing sodium ions to flow into the cell, depolarizing the membrane.
- Threshold: If depolarization reaches a certain threshold, an action potential is triggered.
- Propagation: The action potential propagates along the axon as sodium channels open ahead of the wave, while potassium channels behind it repolarize the membrane.
7. Discuss the role of hormones in regulating blood sugar levels.
Hormones play a crucial role in regulating blood sugar levels:
- Insulin: Secreted by the pancreas, insulin promotes glucose uptake by cells and inhibits gluconeogenesis.
- Glucagon: Also secreted by the pancreas, glucagon stimulates gluconeogenesis and glycogen breakdown, raising blood sugar levels.
- Epinephrine (adrenaline): Released by the adrenal gland in response to stress, epinephrine triggers glycogen breakdown and gluconeogenesis.
- Cortisol: Produced by the adrenal gland, cortisol stimulates gluconeogenesis and protein breakdown, contributing to increased blood sugar.
8. Explain the concept of negative feedback in physiological systems.
Negative feedback is a common mechanism in physiological systems that helps maintain homeostasis:
- Stimulus: A change in the body triggers a response.
- Receptor: Sensory receptors detect the change and send signals to a control center.
- Control center: The control center processes the signals and initiates a counter-response.
- Effector: The counter-response acts on the effector organ or system to oppose the original change.
- Return to set point: The counter-response continues until the original change is reversed, returning the system to its set point.
9. Describe the role of the kidney in regulating acid-base balance.
The kidneys play a vital role in acid-base balance:
- Reabsorption: The kidneys reabsorb bicarbonate ions, which helps maintain blood pH.
- Excretion: The kidneys excrete hydrogen ions and ammonium ions, which helps prevent acidosis.
- Production of new bicarbonate ions: The kidneys can produce new bicarbonate ions through the reabsorption of filtered bicarbonate and the secretion of hydrogen ions into the urine.
10. Discuss the factors that affect respiratory rate and depth.
Respiratory rate and depth are influenced by several factors:
- Chemical factors: Changes in blood pH and carbon dioxide levels stimulate receptors in the respiratory center, adjusting breathing.
- Neural factors: Inputs from the cerebral cortex, medulla, and pons can modify respiratory rate and depth.
- Mechanical factors: Lung volume, airway resistance, and chest wall compliance can impact breathing.
- Hormonal factors: Hormones like epinephrine and progesterone can alter respiratory rate and depth.
