Verified step by step guidance

Understand the structure of the spinal cord: The spinal cord is divided into gray matter and white matter. Gray matter contains neuron cell bodies, dendrites, and unmyelinated axons, while white matter contains myelinated axons organized into tracts.

Identify the components of gray matter: The gray matter of the spinal cord is organized into regions called horns. These include the ventral horn (motor neurons), dorsal horn (sensory neurons), and lateral horn (autonomic neurons in certain regions).

Understand the function of white matter: White matter is organized into funiculi (columns), which are bundles of myelinated axons that carry information to and from the brain. Examples include the posterior funiculus, lateral funiculus, and anterior funiculus.

Compare the options provided: The ventral horn, dorsal horn, and lateral horn are all part of the gray matter of the spinal cord. The posterior funiculus, however, is part of the white matter and is responsible for transmitting sensory information.

Conclude that the posterior funiculus is NOT part of the gray matter of the spinal cord, as it is a white matter structure involved in sensory signal transmission.
