Rexed laminae, the Glossary

Index Rexed laminae

The Rexed laminae (singular: Rexed lamina) comprise a system of ten layers of grey matter (I–X), identified in the early 1950s by Bror Rexed to label portions of the grey columns of the spinal cord.[1]

Accessory nerve

The accessory nerve, also known as the eleventh cranial nerve, cranial nerve XI, or simply CN XI, is a cranial nerve that supplies the sternocleidomastoid and trapezius muscles.

See Rexed laminae and Accessory nerve

Anterior grey column

The anterior grey column (also called the anterior cornu, anterior horn of spinal cord, motor horn or ventral horn) is the front column of grey matter in the spinal cord. Rexed laminae and anterior grey column are spinal cord.

See Rexed laminae and Anterior grey column

Brodmann area

A Brodmann area is a region of the cerebral cortex, in the human or other primate brain, defined by its cytoarchitecture, or histological structure and organization of cells.

Bror Rexed

Bror Anders Rexed (19 June 1914 – 21 August 2002) was a Swedish neuroscientist and professor at Uppsala University.

Central canal

The central canal (also known as spinal foramen or ependymal canal) is the cerebrospinal fluid-filled space that runs through the spinal cord. Rexed laminae and central canal are spinal cord.

See Rexed laminae and Central canal

Grey column

The grey column refers to a somewhat ridge-shaped mass of grey matter in the spinal cord. Rexed laminae and grey column are spinal cord.

See Rexed laminae and Grey column

Grey matter

Grey matter, or brain matter in American English, is a major component of the central nervous system, consisting of neuronal cell bodies, neuropil (dendrites and unmyelinated axons), glial cells (astrocytes and oligodendrocytes), synapses, and capillaries.

See Rexed laminae and Grey matter

Intermediolateral nucleus

The intermediolateral nucleus (IML) is a region of grey matter found in one of the three grey columns of the spinal cord, the lateral grey column. Rexed laminae and intermediolateral nucleus are spinal cord.

See Rexed laminae and Intermediolateral nucleus

Interneuron

Interneurons (also called internuncial neurons, relay neurons, association neurons, connector neurons, intermediate neurons or local circuit neurons) are neurons that connect to brain regions, i.e. not direct motor neurons or sensory neurons.

See Rexed laminae and Interneuron

Lateral grey column

The lateral grey column (lateral column, lateral cornu, lateral horn of spinal cord, intermediolateral column) is one of the three grey columns of the spinal cord (which give the shape of a butterfly); the others being the anterior and posterior grey columns. Rexed laminae and lateral grey column are spinal cord.

See Rexed laminae and Lateral grey column

Marginal nucleus of spinal cord

The marginal nucleus of spinal cord, or posteromarginal nucleus, Rexed lamina I, is located at the most dorsal aspect of the dorsal horn of the spinal cord. Rexed laminae and marginal nucleus of spinal cord are spinal cord.

See Rexed laminae and Marginal nucleus of spinal cord

Nucleus proprius of spinal cord

The nucleus proprius is a layer of the spinal cord adjacent to the substantia gelatinosa. Rexed laminae and nucleus proprius of spinal cord are spinal cord.

See Rexed laminae and Nucleus proprius of spinal cord

Onuf's nucleus

Onuf's nucleus is a distinct group of neurons located in the ventral part (lamina IX) of the anterior horn of the sacral region of the human spinal cord involved in the maintenance of micturition and defecatory continence, as well as muscular contraction during orgasm. Rexed laminae and Onuf's nucleus are spinal cord.

See Rexed laminae and Onuf's nucleus

Phrenic nerve

The phrenic nerve is a mixed motor/sensory nerve that originates from the C3-C5 spinal nerves in the neck.

See Rexed laminae and Phrenic nerve

Posterior grey column

The posterior grey column (posterior cornu, dorsal horn, spinal dorsal horn, posterior horn, sensory horn) is one of the three grey columns of the spinal cord. Rexed laminae and posterior grey column are spinal cord.

See Rexed laminae and Posterior grey column

Posterior thoracic nucleus

The posterior thoracic nucleus, (Clarke's column, column of Clarke, dorsal nucleus, nucleus dorsalis of Clarke) is a group of interneurons found in the medial part of lamina VII, also known as the intermediate zone, of the spinal cord. Rexed laminae and posterior thoracic nucleus are spinal cord.

See Rexed laminae and Posterior thoracic nucleus

Postganglionic nerve fibers

In the autonomic nervous system, nerve fibers from the ganglion to the effector organ are called postganglionic nerve fibers.

See Rexed laminae and Postganglionic nerve fibers

Preganglionic nerve fibers

In the autonomic nervous system, nerve fibers from the central nervous system to the ganglion are known as preganglionic nerve fibers.

See Rexed laminae and Preganglionic nerve fibers

Spinal cord

The spinal cord is a long, thin, tubular structure made up of nervous tissue that extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column (backbone) of vertebrate animals.

See Rexed laminae and Spinal cord

Splanchnic nerves

The splanchnic nerves are paired visceral nerves (nerves that contribute to the innervation of the internal organs), carrying fibers of the autonomic nervous system (visceral efferent fibers) as well as sensory fibers from the organs (visceral afferent fibers).

See Rexed laminae and Splanchnic nerves

Substantia gelatinosa of Rolando

The apex of the posterior grey column, one of the three grey columns of the spinal cord, is capped by a V-shaped or crescentic mass of translucent, gelatinous neuroglia, termed the substantia gelatinosa of Rolando (or SGR) (or gelatinous substance of posterior horn of spinal cord), which contains both neuroglia cells, and small neurons. Rexed laminae and substantia gelatinosa of Rolando are spinal cord.

See Rexed laminae and Substantia gelatinosa of Rolando

Terminal cisternae

Terminal cisternae (singular: terminal cisterna) are enlarged areas of the sarcoplasmic reticulum surrounding the transverse tubules.
