No, those are in the brain. The Brain Stem and the Spinal Cord are for reflexes and transmitting nervous messages to the brain.

What is the brainstem used for?
The brainstem provides the main motor and sensory innervation to the face and neck via the cranial nerves. The brainstem also plays an important role in the regulation of cardiac and respiratory function.
Which part of the hindbrain is involved in sleep and arousal?
Non-sexual arousal (such as motor function) is centered in the brainstem.
What is Anarthia?
Loss of the motor ability that enables speech.
What lobe is the Motor speech area located?
Frontal lobe
What causes unilateral upper motor neuron dysarthria?
Unilateral UMN dysarthria is caused by damage to either the left or right UMN tract, anywhere along its course to the brainstem and spinal cord.
What centers of the brain receive information from many association areas and direct extremely complex motor activities such as speech?
The Integrative Centers of the Cerebrum
Will difficulty in breathing reflect damage to respiratory centers located in the cerebellum?
No, difficulty in breathing is not typically associated with damage to the respiratory centers located in the cerebellum. The cerebellum is primarily involved in coordinating motor movements and balance, not respiration. Damage to the respiratory centers located in the brainstem, particularly in the medulla oblongata, is more likely to affect breathing function.
What is a degenerative deterioration of the nerves in the brainstem calledprimarily the motor area called?
Parkinson's Disease
Where is the brainstem located?
The brainstem contains ascending and descending nerve pathways that carry sensory input and motor output information to and from higher brain regions
How long is the brainstem?
The brain stem is relatively short, around 7-centimeters long. The brainstem provides the main motor and sensory innervation to the face and neck via the cranial nerves.
What is the neuron inside the spinal cord?
Alpha motor neurons (α-MNs) are large lower motor neurons of the brainstem and spinal cord.
What is the brainstem used for?
The brainstem provides the main motor and sensory innervation to the face and neck via the cranial nerves. The brainstem also plays an important role in the regulation of cardiac and respiratory function.
Where are centers for control of the motor repetitious or stereotyped motor skills are found?
Primary Motor
What is the function of motor speech?
The motor speech center (Brocas area) is located in the left hemisphere and memorizes breathing and vocalization patterns required for speech.
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.
What is a motor speech disorder?
It is a disorder affecting the motor abilities of speech. These would include articulation, some types of aphasia, and apraxia.
What narrow structure connects the cerebellar hemispheres?
The pons connects the cerebrum to the cerebellum. The cerebellum is responsible for the motor control in the brain.
