What are the key features and functions of the spinal cord as described in the handout?
Understand the Problem
The question is asking for detailed information about the anatomy and functions of the spinal cord based on a handout. It covers aspects such as the organization of white and grey matter, various nuclei, and their corresponding functions, especially related to pain modulation and sensory processing.
Answer
White matter for signaling, grey matter for sensory/motor control, central canal for CSF.
The handout outlines the spinal cord's key features and functions: White matter enables signal transmission via myelinated axons. Grey matter, forming an 'H' shape with nuclei, manages sensory, motor, and autonomic functions. The central canal contains cerebrospinal fluid. Specific nuclei within grey matter regulate pain modulation and proprioception.

More Information
Substantia gelatinosa in grey matter plays a crucial role in pain modulation by releasing enkaphalins to inhibit pain signals.
Tips
A common mistake is confusing the white and grey matter functions. White matter is mainly for signal transmission, while grey matter contains nerve nuclei crucial for processing.
