Central Nervous System (CNS)

The human nervous system is divided into the , consisting of the brain and spinal cord, and the Peripheral Nervous System (PNS) . The CNS acts as the primary processing center, protected by the bony structures of the skull and vertebral column, as well as three layers of membranes known as the meninges (dura mater, arachnoid mater, and pia mater). II. Major Divisions of the Brain

• Central Nervous System (CNS): The CNS consists of the brain and spinal cord. It is responsible for integrating and processing information from various sensory inputs, controlling voluntary movements, and facilitating thought, emotion, and behavior.
• Peripheral Nervous System (PNS): The PNS consists of nerves that connect the CNS to the rest of the body. It is responsible for transmitting sensory information from the body to the CNS and motor signals from the CNS to muscles and glands.

Peripheral Nervous System (PNS):

Consisting of cranial and spinal nerves that connect the CNS to the rest of the body. 2. Gross Anatomy of the Brain neuroanatomy notes pdf

Understanding neuroanatomy is the prerequisite for understanding neurology and psychiatry. By mastering the subdivisions of the CNS, the pathways of the cranial nerves, and the cellular makeup of nervous tissue, students can visualize the physical map that makes human consciousness and physical action possible.
