Motor system, the Glossary
The motor system is the set of central and peripheral structures in the nervous system that support motor functions, i.e. movement.[1]

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.
See Motor system and Anterior grey column
Axon
An axon (from Greek ἄξων áxōn, axis) or nerve fiber (or nerve fibre: see spelling differences) is a long, slender projection of a nerve cell, or neuron, in vertebrates, that typically conducts electrical impulses known as action potentials away from the nerve cell body.
Basal ganglia
The basal ganglia (BG) or basal nuclei are a group of subcortical nuclei found in the brains of vertebrates.
See Motor system and Basal ganglia
Betz cell
Betz cells (also known as pyramidal cells of Betz) are giant pyramidal cells (neurons) located within the fifth layer of the grey matter in the primary motor cortex.
See Motor system and Betz cell
Biological system
A biological system is a complex network which connects several biologically relevant entities.
See Motor system and Biological system
Brainstem
The brainstem (or brain stem) is the stalk-like part of the brain that connects the forebrain (the cerebrum and diencephalon) with the spinal cord.
See Motor system and Brainstem
Central nervous system
The central nervous system (CNS) is the part of the nervous system consisting primarily of the brain and spinal cord.
See Motor system and Central nervous system
Cerebellum
The cerebellum (cerebella or cerebellums; Latin for "little brain") is a major feature of the hindbrain of all vertebrates.
See Motor system and Cerebellum
Cerebral cortex
The cerebral cortex, also known as the cerebral mantle, is the outer layer of neural tissue of the cerebrum of the brain in humans and other mammals.
See Motor system and Cerebral cortex
Circulatory system
The circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the entire body of a human or other vertebrate.
See Motor system and Circulatory system
Corona radiata
In neuroanatomy, the corona radiata is a white matter sheet that continues inferiorly as the internal capsule and superiorly as the centrum semiovale.
See Motor system and Corona radiata
Decussation
Decussation is used in biological contexts to describe a crossing (due to the shape of the Roman numeral for ten, an uppercase 'X' (decussis)). In Latin anatomical terms, the form decussatio is used, e.g. decussatio pyramidum.
See Motor system and Decussation
In anatomy, the extrapyramidal system is a part of the motor system network causing involuntary actions.
See Motor system and Extrapyramidal system
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 Motor system and Grey matter
Internal capsule
The internal capsule is a white matter structure situated in the inferomedial part of each cerebral hemisphere of the brain.
See Motor system and Internal capsule
Lateral funiculus
The most lateral of the bundles of the anterior nerve roots is generally taken as a dividing line that separates the anterolateral system into two parts.
See Motor system and Lateral funiculus
Limb (anatomy)
A limb (from Old English lim, meaning "body part") is a jointed, muscled appendage of a tetrapod vertebrate animal used for weight-bearing, terrestrial locomotion and physical interaction with other objects.
See Motor system and Limb (anatomy)
Lower motor neuron
Lower motor neurons (LMNs) are motor neurons located in either the anterior grey column, anterior nerve roots (spinal lower motor neurons) or the cranial nerve nuclei of the brainstem and cranial nerves with motor function (cranial nerve lower motor neurons).
See Motor system and Lower motor neuron
Medulla oblongata
The medulla oblongata or simply medulla is a long stem-like structure which makes up the lower part of the brainstem.
See Motor system and Medulla oblongata
Motor control
Motor control is the regulation of movements in organisms that possess a nervous system.
See Motor system and Motor control
Motor disorder
Motor disorders are disorders of the nervous system that cause abnormal and involuntary movements.
See Motor system and Motor disorder
Motor skill
A motor skill is a function that involves specific movements of the body's muscles to perform a certain task. Motor system and motor skill are motor control.
See Motor system and Motor skill
Muscle
Muscle is a soft tissue, one of the four basic types of animal tissue.
Muscular system
The muscular system is an organ system consisting of skeletal, smooth, and cardiac muscle.
See Motor system and Muscular system
Nerve
A nerve is an enclosed, cable-like bundle of nerve fibers (called axons) in the peripheral nervous system.
Nervous system
In biology, the nervous system is the highly complex part of an animal that coordinates its actions and sensory information by transmitting signals to and from different parts of its body.
See Motor system and Nervous system
Neuron
A neuron, neurone, or nerve cell is an excitable cell that fires electric signals called action potentials across a neural network in the nervous system.
Peripheral nervous system
The peripheral nervous system (PNS) is one of two components that make up the nervous system of bilateral animals, with the other part being the central nervous system (CNS).
See Motor system and Peripheral nervous system
Pyramidal tracts
The pyramidal tracts include both the corticobulbar tract and the corticospinal tract.
See Motor system and Pyramidal tracts
Skeletal muscle
Skeletal muscle (commonly referred to as muscle) is one of the three types of vertebrate muscle tissue, the other being cardiac muscle and smooth muscle.
See Motor system and Skeletal muscle
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 Motor system and Spinal cord
Upper motor neuron
Upper motor neurons (UMNs) is a term introduced by William Gowers in 1886.
See Motor system and Upper motor neuron
White matter
White matter refers to areas of the central nervous system (CNS) that are mainly made up of myelinated axons, also called tracts.
See Motor system and White matter
