Where do upper neurons descend on lower neurons?
Movement is controlled by motor neurons that innervate muscles. Motor neurons can be classified by their location as upper motor neurons or lower motor neurons.Upper motor neurons have cell bodies in the somatosensory and motor cortex of the brain that send axons down to the spinal cord or brainstem. Upper motor neurons descend through the posterior limb of the internal capsule in the cerebrum, through the crus cerebri of the midbrain, through the basilar pons, through the medullary pyramids, crossing midline at the pyramidal decussation in the caudal medulla, and descending through the anterior and lateral corticospinal tracts of the spinal cord to terminate at their respective ventral horn levels. Corticobulbar fibers are upper motor neurons that innervate brainstem nuclei for cranial nerves. They descend through the genu of the internal capsule of the cerebrum to various brainstem cranial nerve nuclei or reticular formation nuclei that innervate brainstem cranial nerve nuclei.Lower motor neurons have cell bodies in the ventral horns throughout the spinal cord. These motor neurons receive excitation information from the upper motor neurons as well as a large amount of modulating input from a variety of other neuronal sources. For cranial nerves the lower motor neurons are located within the brainstem cranial nerve nuclei: occulomotor nucleus, trochlear nucleus, abducens nucleus, trigeminal motor nucleus, facial nucleus, spinal accessory nucleus, hypoglossal nucleus, & nucleus ambiguous.
The descending pathway from the red nucleus to the lower motor neurons is the Tract?
The descending pathway from the red nucleus to the lower motor neurons is known as the rubrospinal tract. This tract plays a role in the coordination of movement and the regulation of muscle tone, particularly in the upper limbs. It originates in the red nucleus of the midbrain and descends to influence motor neurons in the spinal cord, primarily facilitating flexor muscle activity.
Where are the neurons found in the atom?
Neurons are not found in atoms as they are much larger structures made up of molecules and cells. Neurons are specialized cells found in the nervous system and are essential for transmitting information throughout the body.
What are the names of cell bodies in neurons?
Cell bodies in neurons are called soma or perikaryon. They contain the nucleus and most of the organelles responsible for the cell's metabolic activities.
WHERE ARE THE TWO TYPES OF SUBATOMIC PARTICLES LOCATED IN SILICON?
Protons and neurons are in nucleus. electrons orbit around them
Are neurons located in an atoms nucleus?
Neurons are nerve cells. Unless you mean neutrons which are located in the nucleus of an atom.
What is neurons transmit signals across a?
the nucleus.
What type of cell does not have a nucleus or other organells?
neurons
Where do second-order neurons synapse with third-order neurons?
ventral posterolateral nucleus of the thalamusthalamusin the thalamus
How do neurons from proprioceptors relay messages to the cerebellum?
A. Inferior olivary nucleus

The nucleus is made up of?
Im pretty sure that they are made up of neurons and protons

What contains the nucleus?
The cell nucleus contains the chromosomes, and therefore the DNA The term 'nucleus' has a different meaning when talking about the nervous system; in this instance the nucleus is the cell body of neurons within the CNS
