- DTo process speech and hearing
Correct answer
A. To protect the brain from damage
Step-by-step solution
The brain acts as the "command and control system" and controls various functions such as voluntary movements, balance, vital organs, circadian rhythms, endocrine glands and human behavior. The brain is divided into three major parts, the forebrain, midbrain, and hindbrain, which are the main regions that control different functions in the body.The cranial meninges consisting of dura mater, arachnoid and pia mater protect the brain and act as a protective layer. The forebrain is responsible for processing vision, hearing, speech, memory, intelligence, emotions and thoughtsMid- brain does not have any of the above functions.
The outer layer of the cranial meninges is called the dura mater. The inner layer of the cranial meninges, which is in contact with the brain tissue, is called the pia mater.The hindbrain is one of the three major parts of the brain but its specific functions are not mentioned in the given text.
