Which part of the brain is responsible for thermoregulation?
Hypothalamus
Corpus callosum
Medulla oblongata
Cerebrum
A.
Hypothalamus
Hypothalamus in the thermoregulatory centre of our brain. It is responsible for maintaining constant body temperature.
Which of the following statements is correct?
Cornea consists of dense connective tissue of elastin and can repair itself.
Cornea is convex, transparent layer which is highly vascularised.
Cornea consists of dense matrix of collagen and is the most sensitive portion the eye.
Cornea is an external, transparent and protective proteinacious covering of the eye-ball.
C.

Cornea consists of dense matrix of collagen and corneal epithelium. It is the most sensitive part of eye.
Organ of Corti is found in
heart
kidneys
inner ear
nasal chamber
C.
inner ear
Organ of Corti are found in cochlear channel (internal ear) and are responsible for hearing. Ear is concerned both with hearing and balance, semicircular canals are responsible for balance when body is in motion.
If medulla oblongata is destroyed then which of the following functions will be effected
No thermoregulation
No vision
No memory
No response when pricked with needle
D.
No response when pricked with needle
Medulla oblongata is part of the vertebrate brain stem, derived from the hindbrain, that is continuous with the spinal cord. Its function is to regulate the reflex responses controlling respiration, heart beat, blood pressure, and other involuntary processes. It gives rise to many of the cranial nerves.
What is cochlear microphonics?
Cochlear microphonic is the electrical potential generated in the hair cells of the organ of Corti in response to acoustic stimulation.
