Difference between Alpha motor neuron and Spinal cord

Alpha motor neuron vs. Spinal cord

Alpha (α) motor neurons (also called alpha motoneurons), are large, multipolar lower motor neurons of the brainstem and spinal cord. The spinal cord is a long, thin, tubular bundle of nervous tissue and support cells that extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column.

Similarities between Alpha motor neuron and Spinal cord

Action potential

In physiology, an action potential occurs when the membrane potential of a specific axon location rapidly rises and falls: this depolarisation then causes adjacent locations to similarly depolarise.

Alar plate

The alar plate (or alar lamina) is a neural structure in the embryonic nervous system, part of the dorsal side of neural tube, that involves the communication of general somatic and general visceral sensory impulses.

Anterior grey column

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

Axon

An axon (from Greek ἄξων áxōn, axis) or nerve fiber, is a long, slender projection of a nerve cell, or neuron, that typically conducts electrical impulses known as action potentials, away from the nerve cell body.

Brainstem

The brainstem (or brain stem) is the posterior part of the brain, adjoining and structurally continuous with the spinal cord.

Central nervous system

The central nervous system (CNS) is the part of the nervous system consisting of the brain and spinal cord.

Cerebral cortex

The cerebral cortex is the largest region of the cerebrum in the mammalian brain and plays a key role in memory, attention, perception, cognition, awareness, thought, language, and consciousness.

Cervical enlargement

The cervical enlargement corresponds with the attachments of the large nerves which supply the upper limbs.

Corticospinal tract

The corticospinal tract is a white matter motor pathway starting at the cerebral cortex that terminates on lower motor neurons and interneurons in the spinal cord, controlling movements of the limbs and trunk.

Floor plate

The floor plate is a structure integral to the developing nervous system of vertebrate organisms.

Grey matter

Grey matter (or gray matter) is a major component of the central nervous system, consisting of neuronal cell bodies, neuropil (dendrites and myelinated as well as unmyelinated axons), glial cells (astrocytes and oligodendrocytes), synapses, and capillaries.

Lumbar enlargement

The lumbar enlargement (or lumbosacral enlargement) is a widened area of the spinal cord that gives attachment to the nerves which supply the lower limbs.
