Spinal cord
The spinal cord is the part of the central nervous system located in the spine. It contains both the white matter of the nerve fibers and the gray matter of the cell nuclei. Simple reflexes such as the knee-jerk reflex are already processed here, as sensory and motor neurons are directly connected. The spinal cord is divided into the cervical, thoracic, lumbar, and sacral spinal cord.

Plaques
Senile plaques accumulate in the gray matter of the brain when a protein – known as amyloid precursor protein – is not broken down correctly. Inflammation and disorders of fat or sugar metabolism can promote plaque formation. On average, the deposits reach a diameter of 50 micrometers. The appearance of plaques is one of several anatomical changes in the brain that pathologists can use to diagnose Alzheimer's disease after death.

Nucleus
Nucleus, plural nuclei, has two meanings: in cell biology, it refers to the cell nucleus, which contains chromosomes, among other things. In neuroanatomy, it refers to a collection of cell bodies in the nervous system – in the central nervous system as gray matter, in the peripheral nervous system as ganglia.

Cerebellar cortex
The cortex of the cerebellum, which, like that of the cerebrum, is composed of gray matter, or nerve cells. It consists of three layers and is highly folded, creating what are known as foliae, or leaves.
