The correct Answer is:
To answer the question, we will fill in the blanks step by step based on the information provided in the video transcript. ### Step-by-Step Solution: 1. **Identify the center in the medulla region of the brain responsible for respiration regulation.** - The specialized center present in the medulla region of the brain is called the **Respiratory Rhythm Center (RRC)**. This center is primarily responsible for regulating the process of respiration. - **Answer for A:** Respiratory Rhythm Center (RRC) 2. **Identify the center in the pons region of the brain that moderates the functions of the RRC.** - The center present in the pons region of the brain is known as the **Pneumotaxic Center**. This center can moderate the functions of the Respiratory Rhythm Center. - **Answer for B:** Pneumotaxic Center 3. **Determine how the neural signals from the Pneumotaxic Center affect the duration of inspiration.** - Neural signals from the Pneumotaxic Center can **decrease** the duration of inspiration, thereby altering the respiratory rate. - **Answer for C:** Decrease 4. **Identify the area situated adjacent to the rhythm center that is sensitive to certain stimuli.** - The area situated adjacent to the Respiratory Rhythm Center is known as the **Chemosensitive Area**. This area is highly sensitive to changes in carbon dioxide (CO2) and hydrogen ions (H+). - **Answer for D:** Chemosensitive Area 5. **Identify what the Chemosensitive Area is sensitive to.** - The Chemosensitive Area is highly sensitive to **carbon dioxide (CO2)** levels in the blood, as well as hydrogen ions (H+). - **Answer for E:** CO2 (carbon dioxide) ### Final Answers: - A: Respiratory Rhythm Center (RRC) - B: Pneumotaxic Center - C: Decrease - D: Chemosensitive Area - E: CO2 (carbon dioxide)

Fill up the blanks in the following paragraph by selecting the correct option. Human beings have a significant ability to maintain and moderate the respiratory rhythm to suti the demands of the body tissues. This is done by the neural system. A specialised centre present in the medulla region of the brain called overset((i))"_______" is primarily responsible for this regulation. Another centre present in the pons region of the brain called overset((ii))"_______" can moderate the functions of the repiratory rhytm cenre. Neutral signal from this cenre cen reduce the duration of overset((iii))"_______" and thereby alter the respiratory rate. A overset((iv))"_______" is situated adjacent to the rhythm centre which is highly sensitive to CO_(2) and hydrogen ions.

Assertion : Pneumotaxic centre, located in the medulla region of the brain, moderates the respiratory rhythm centre. Reason : Pneumotaxic centre controls the switch 'ON' point of inspiration.

Which of the following statements are CORRECT ? I. A specialized center present in the medulla region of the brain called respiratory rhythm center is primarily responsible for the regulation of respiration. II. A Chemosensitive area is situated adjacent to the rhythm which is highly sensitive to O_2,CO_2 and hydrogen ions . III . Receptors associated with aortic arch and carotid artery also can recognize changes in CO_2 and H^+ concentration and send necessary signals to the rhythm center for remedial actions. IV The neural signal from the pneumatic center can increase the duration of inspiration and thereby alter the respiratory rate .

Pick out the correct statements: a) Pneumotaxic centre moderates the functioning of respiratory rhythm centre. b) Pneumotaxic centre is primarily responsible for regulation of respiratory movements. c) Decrease in pH of cerebrospinal fluid is detected by medulla. d) The role of carbon dioxide in the regulation of respiratory rhythm is quite insignificant.
