Central Nervous System (CNS) Components:
• The CNS comprises two primary structures: the Brain and the Spinal Cord.
• Protective mechanisms: The brain is encased within the cranium (skull) and cushioned by cerebrospinal fluid (CSF) against impacts.
• The spinal cord is safeguarded by the vertebral column (spine) and is also bathed in cerebrospinal fluid (CSF), serving as a shock-absorbing medium.
