Motor neuron diagram. 2 a bipolar neuron. Google classroom facebook twitter. Difference between sensory and motor neuron. A motor neuron or motoneuron is a neuron whose cell body is located in the motor cortex brainstem or the spinal cord and whose axon fiber projects to the spinal cord or outside of the spinal cord to directly or indirectly control effector organs mainly muscles and glands. This is the currently selected item. Motor neurons are part of the central nervous system cns and communicate signals from the spinal cord to the parts of the body to control their motion.

Dendritesa branch like structure that functions by receiving messages from other neurons and allow the transmission of messages to the. A motor neuron is one of the three types of neurons involved in this process. Overview of neuron structure and function. Motor neuron disease mnd a motor neuron disease affects the normal functioning of motor neurons resulting in their degeneration and death.
Cerebellum control over lower motor neuron is mediated through either motor cortex or red nucleus or reticular nucleus or vestibular nucleus fig. Motor function cannot be smooth in the absence of afferent impulses coming from peripheral parts of body. The neuron is an individual specialized cell which is also known as the nerve cell a group of neurons form a nerve. There are two types of motor neuron upper motor neurons and lower motor neurons. Motor neuron diseases or motor neurone diseases mnds are a group of rare neurodegenerative disorders that selectively affect motor neurons the cells which control voluntary muscles of the body.
