What section of the brain is located inferior to the cerebrum and posterior to the brainstem?
The cerebellum is located inferior to the cerebrum and posterior to the brainstem. It plays a key role in motor control, coordination, balance, and posture.
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.
What causes unilateral upper motor neuron dysarthria?
Unilateral upper motor neuron dysarthria can be caused by lesions in the corticobulbar pathway on one side of the brain, such as a stroke, tumor, or traumatic brain injury. These lesions can disrupt the connection between the motor areas of the brain and the cranial nerve nuclei responsible for speech production on that side, leading to impaired control over speech muscles.
Which of the following lists the hierarchy of motor control from lowest to highest level of control?
Hierarchy motor control from lowest to highest:Segmental levelProjection levelPrecommand level
The little brain attached to the rear of the brainstem is called?
The little brain attached to the rear of the brainstem is called the cerebellum. It plays a key role in motor coordination and balance, helping to fine-tune movements initiated by the brain.
What centers of the brain receive information from many association areas and direct extremely complex motor activities such as speech?
The primary motor cortex in the frontal lobe receives information from association areas and is involved in directing complex motor activities such as speech production. Additionally, the basal ganglia and cerebellum also play crucial roles in coordinating and fine-tuning motor movements necessary for speech.
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 centers receive information from many association areas and direct extremely complex motor activities such as speech?
The Broca's area in the frontal lobe of the brain is responsible for coordinating complex motor activities involved in speech production. It receives input from a network of association areas involved in language processing to enable fluent and coordinated speech.
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
What is the neuron inside the spinal cord?
Alpha motor neurons (α-MNs) are large lower motor neurons of the brainstem and spinal cord.
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 section of the brain is located inferior to the cerebrum and posterior to the brainstem?
The cerebellum is located inferior to the cerebrum and posterior to the brainstem. It plays a key role in motor control, coordination, balance, and posture.
Where are centers for control of the motor repetitious or stereotyped motor skills are found?
Primary Motor
What is a degenerative deterioration of the nerves in the brainstem calledprimarily the motor area called?
The degenerative deterioration of the nerves in the brainstem, primarily affecting the motor area, is called Amyotrophic Lateral Sclerosis (ALS). This condition leads to progressive muscle weakness and eventually paralysis due to the loss of motor neurons in the brain and spinal cord.
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.
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.
What causes unilateral upper motor neuron dysarthria?
