Question

The thermoregulatory centre is situated in
A. Spinal cord
B. Pituitary body
C. Cerebellum
D. Hypothalamus

Answer 1

Hint: The temperature at which enzymes work best is maintained by the human body. Thermoregulation is a mechanism. The process enables the human body to preserve its internal core temperature. The thermoregulatory centre contains blood temperature-sensitive receptors. The skin also has receptors for temperature and sends back nervous impulses to this organ.

Complete answer:
- Spinal cord: The funiculus may be a long, thin, tubular structure. It's made of nerve tissue, which extends from the neural structure within the brainstem to the lumbar region of the rachis. It encloses the central canal of the funiculus, which contains humor. Hence option A is wrong.
- Pituitary body: The ductless gland could be a part of your system. Secrete hormones into the bloodstream are the main function of it. Hence option B is wrong.
- Cerebellum: The cerebellum could be a major structure of the hindbrain. It's located near the brainstem. The cerebellum receives information from the sensory systems, the neural structure, and other parts of the brain and so regulates motor movements. Hence option C is wrong.
- Hypothalamus: Hypothalamus maintains the constant body temperature by regulation of the diameter of blood vessels (constriction to conserve heat during temperature less than normal or dilation to lose heat by increasing blood flow during blood heat beyond the conventional range), shivering and sweating mechanisms. Hence option D is correct.
Hence option ‘D: Hypothalamus’ is the correct answer.

Note: Thermoregulator could be a center temperature center within the hypothalamus that regulates heat production and warmth loss, in order that a standard vital sign is maintained. it's influenced by nerve impulses from cutaneous receptors and by the temperature of the blood flowing through it.
