Ultimately a motor neuron is involved in the pathway of sending information from your brain to your muscles, thus allowing your brain to control the movements of your body. As an analogy, think of your computer and the printer to which it is attached. The computer is your brain, the printer is the muscle that needs to perform an action, and the cable connecting the two is the motor neuron.
A neuron is a cell in the central nervous system that has a cell body and a very long extension called an axon. There are two levels of motor neurons in your body, the upper motor neuron and the lower motor neuron. The upper motor neurons originate from the cortex of the brain and project their axons down to the spinal cord to terminate in the ventral horns of the spinal cord. The ventral horn in the spinal cord is a column of grey matter located towards the front (or the ventral side) in the spinal cord. In the ventral horn of the spinal cord, the axons of the upper motor neurons synapse with lower motor neurons, whose cell bodies are located in the ventral horn. The lower motor neurons then have axons that exit the spinal cord and leave through nerve roots, to the peripheral nerves of your body, and eventually to the muscles that control your movement. Some of the lower motor neurons that control facial movement are located in the brainstem and not the spinal cord.
Motor neurons can also be classified functionally by what they do, i.e. general somatic efferent neurons, general visceral efferent motor neurons, or special visceral efferent motor neurons.
This can get much more complicated when we take into account the amount of descending input from the brain, brainstem, and cerebellum; and the integration that occurs at the level of the lower motor neuron cell body. Most simplistically, the function of the motor neuron is to transmit the message from the brain to the muscle.
Diseases of motor neurons, such as amyotrophic lateral sclerosis and spinal muscular atrophy, can be very serious and currently have no cure.
What else can I help you with?
What type of nuerons conduct nerve impulses along an efferent pathway?
Motor neurons
What type of venom affects the nuerons?
Neurotoxins
What is the gap between nuerons called?
A Synapse
How does the human reflex system work?
Reflex actions involve just three types of neurone. These are : - sensory neurones, - motor neurones, and Relay neurones which simply connect a sensory neurone and a motor neurone. We find relay neurones in the CNS, often in spinal cord
What conducts impulses from the brain to glands?
Nerves transmit impulses from the brain to glands. This communication pathway enables the brain to control the release of hormones that regulate various bodily functions.
Three kinds of neurons?
1.sensory neuron- carry impulses from the sensory receptors to the Central Nervous System 2.motor neurons- carry impulses from the Central Nervous System to the muscles and glans 3.association neuron- relay impulses netween sensory and motor neurons -------------------- AD go to bookden.webs.com .. a website for booklovers.. thx
What caries messages from brain to the body?
nuerons otherwise known as nerves
What are the names of the nerve cell?
The names of the nerve cell? I'm not sure I understand the question in it's entirety It's pretty basic nothing overly complex. Well the nueron is comprised of the cell body or the soma, which has branch-like appendages which are called dendrites meaning treelike. The axon which has a covering called the myelin sheath that helps sends messages faster. We have motor nuerons, sensory nuerons and internuerons. Bipolar neurons, psuedounipolar, and multipolar nuerons. As for naming them, they are named for the region they are found/located around. olfactory nuerons, hypoglossal, vagus, accessory, glossopharyngeal etc. . .
Do all nuerons look the same?
No, neurons come in various shapes and sizes depending on their function. There are different types of neurons, such as sensory neurons, motor neurons, and interneurons, each with unique structures specialized for their roles in transmitting information throughout the body.
What are Three types of structures found in a true nervous system?
nuerons(NOO-rahn), Brain
The basic units of the brain spinal cord and nerves that process store and transmit information are the?
nuerons
What is the name for all the nuerons in the central nervous system?
Interneurons
