Explanation -

Cranial Nerves:

  • The cranial nerves are a collection of twelve nerves that emerge from the brain.
  • Each has a distinct sensory or movement function.
    • ​A person's sensory cranial nerves allow them to see, smell, and hear.
    • Muscle movements in the head and neck are controlled by motor cranial nerves.
  • Each nerve is likewise assigned a Roman numeral ranging from I to XII.
  • This is based on their front-to-back location.
  • Because your olfactory nerve is located closest to the front of your skull, it is labeled I.

Additional Information

Spinal nerves:

  • Your PNS includes your spinal nerves.
  • They arise from the spinal cord.
  • There are 31 pairs of spinal nerves in your body.
  • They're categorised by the area of the spine with which they're related.
  • Sensory and motor functions are shared by spinal nerves.
  • That implies they can both deliver sensory information to the CNS and send directives from the CNS to the periphery of your body.

"Too often we try to solve human problem with non-human tools and in terms of non-human data. It is my simple thesis that a human problem requires a human solution. First we have to learn to recognise a human problem when we see one; and second, upon recognising it, we have to learn to deal with it as such and not as it were something else. A human problem to be brought to a human solution requires human data and human tools". Who said this?

There are two rows, each containing 3 numbers. Below are some rules to be used to get the resultant number for each row separately. Use the rule from left to right for each row and find the answer to the question. Rule: 1. If an even number is followed by an even number, then the first number will be subtracted from the second. 2. If an odd number is followed by an odd number, then both will be added. 3. If an odd number is followed by an even number, then the even number will be subtracted from the square of the odd number. 4. If an even number is followed by an odd number, then the odd number will be subtracted from the even number. Row I: 9,11, 34 Row II: 16, 9, 8 What is the difference between the resultant numbers in the first row and the second row
