Human Anatomy and Physiology: VII. Nervous System

11. The temperature of the human body : [U.P.P.C.S. (Pre) (Re. Exam) 2015]

(a) Decreases in winters
(b) Increases in summers
(c) Neither decreases in winters nor increases in summers
(d) Increases in winters

Correct Answer: (c) Neither decreases in winters nor increases in summers

Solution:The temperature of the human body neither decreases in winters nor increases in summers. The usual temperature of the human body is 98.6°F or 37°C and is controlled by the hypothalamus in the brain. The hypothalamus functions as a type of thermostat for the body.

12. The temperature of a normal human body is — [U.P.P.C.S. (Pre) 2017]

(a) 98.4°F
(b) 98°F
(c) 98.8°F
(d) None of the above

Correct Answer: (d) None of the above

Solution:The average of normal temperature of human body is 98.6°F (or 37°C or 310° K). Body temperature can fluctuate throughout the day, and it's typically lowest in the early morning. Factors like age, gender, and activity levels can also affect body temperature. A temperature above 100.4°F (38°C) is generally considered a fever.

Hypothermia: A temperature below 95°F (35°C) indicates hypothermia, a medical emergency.

13. The normal temperature of the human body is — [Jharkhand P.C.S. (Pre) 2013]

(a) 37°C
(b) 98°C
(c) 367 K
(d) None of the above

Correct Answer: (a) 37°C

Solution:The average of normal temperature of human body is 98.6°F (or 37°C or 310° K). Body temperature can fluctuate throughout the day, and it's typically lowest in the early morning. Factors like age, gender, and activity levels can also affect body temperature. A temperature above 100.4°F (38°C) is generally considered a fever.

Hypothermia: A temperature below 95°F (35°C) indicates hypothermia, a medical emergency.

14. Which one of the following parts of the human brain is the regulating centre for swallowing and vomiting? [I.A.S. (Pre) 2007]

(a) Cerebellum
(b) Cerebrum
(c) Medulla oblongata
(d) Pons

Correct Answer: (c) Medulla oblongata

Solution:The medulla oblongata, which is only three centimetre long, connects the higher levels of the brain to the spinal cord and is responsible for controlling several functions of the autonomous nervous system which include : reflex centre of vomiting, coughing, sneezing and swallowing. These reflexes which include the pharyngeal reflex, the swallowing reflex (also known as the palatal reflex) and the masseter reflex can be termed, bulbar reflexes.
