📖 1. Nervous tissue structure

🔑 Key Concepts & Definitions

Nervous tissue: Specialized tissue composed of neurons and glial cells responsible for transmitting electrical and chemical signals.

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

Peripheral Nervous System (PNS): Network of nerves connecting the CNS to limbs and organs, transmitting sensory and motor information.

Neural extracellular matrix: The supportive environment surrounding neurons and glial cells providing structural support.

📝 Essential Points

Nervous tissue primarily consists of neurons and glial cells working together to transmit and support neural signals. This organization enables rapid communication within the body, which is essential for bodily functions. The CNS processes information centrally, handling complex integration, while the PNS transmits sensory input from the body to the CNS and motor commands from the CNS to the body. The structural organization of nervous tissue is designed to facilitate this swift and efficient communication system.
