Q1. The midbrain, located between the thalamus/hypothalamus of the forebrain and pons of the hindbrain, contains a canal that passes through it called the:
  • Cerebral aqueduct
  • Corpus callosum
  • Central canal
  • Fourth ventricle
Q2. The small but critical region of the brain that controls various functions, including temperature regulation, thirst, hunger, and is involved in regulation of endocrine functions, is:
  • Medulla oblongata
  • Pons
  • Midbrain
  • Hypothalamus
Q3. When a stimulus of adequate strength is applied at a site on the polarised membrane, the membrane at that site becomes:
  • freely permeable to Na+.
  • freely permeable to K+.
  • impermeable to Na+.
  • impermeable to K+.
