📖 1. Nervous System Structure

🔑 Key Concepts & Definitions

• Nervous System: A complex network of neurons and supporting cells that transmits signals throughout the body, coordinating actions and sensory information.

• Central Nervous System (CNS): Comprises the brain and spinal cord; responsible for processing and integrating information.

• Peripheral Nervous System (PNS): Consists of all nerves outside the CNS; connects the CNS to limbs, organs, and tissues, facilitating communication.

• Neurons: Specialized nerve cells that transmit electrical and chemical signals; the fundamental units of the nervous system.

• Glial Cells: Supportive cells in the nervous system that provide insulation (myelin), nutrients, and structural support to neurons.

• Myelin Sheath: A fatty layer surrounding axons of many neurons, increasing the speed of electrical signal transmission.

📝 Essential Points

• The nervous system is divided into CNS and PNS, with the CNS acting as the control center and the PNS serving as communication lines.
