If you have obstructive sleep apnea, where your airway becomes repeatedly blocked, you may suffer apnea even during your waking hours, leading to even more excessive daytime sleepiness. If you have sleep apnea, it may actually change the way your brain sends signals to the rest of your body and that helps keep you awake during the day. It’s especially common for those who have sleep apnea as they rarely get enough uninterrupted sleep no matter when they go to bed or when they get up. It’s common for those who have insomnia, who have frequent nightmares, or who do not go to bed early enough. What is excessive daytime sleepiness?Įxcessive daytime sleepiness is the result of not getting a restful night’s sleep. These include men who are overweight and/or over 40 years of age, those with a large neck size, large tonsils, small jaw, or large tongue, those who have a family history of apnea, and those who have a nasal obstruction such as a deviated septum. Though anyone can have sleep apnea regardless of age or medical conditions, there are some who are more prone to the condition than others. There are two types of sleep apnea: central sleep apnea, where the brain does not signal the muscles properly to breathe and is usually due to problems in the respiratory control center, and obstructive sleep apnea, where there is a blockage of the airway causing the interrupted breathing. During a night of sleep, they may stop breathing 100 different times or more, leading to a number of negative consequences. These individuals stop breathing for certain lengths of time. Sleep apnea occurs when a person’s breathing is continually interrupted during sleep. Here is more information on excessive daytime sleepiness and how it could be affecting you, as well as information on how best to treat it. This is a serious condition that can have a negative impact on your career, relationships, and overall well-being. Only the first and the second pair emerge from the cerebrum the remaining ten pairs emerge from the brainstem.Do you find yourself needing to nap frequently during the day? Do you suffer from brain fog, lack of concentration, or inability to focus? If so, you may have excessive daytime sleepiness due to sleep apnea. In humans, there are traditionally twelve pairs of cranial nerves. Human Brain with Cranial Nerves: Cranial nerves are nerves that emerge directly from the brain, in contrast to spinal nerves, which emerge from segments of the spinal cord. The brainstem also has integrative functions, including cardiovascular system control, respiratory control, pain sensitivity control, alertness, awareness, and consciousness. In addition, upper motor neurons originate in the brain stem’s vestibular, red, tectal, and reticular nuclei, which also descend and synapse in the spinal cord.
The facial sensations have similar pathways and also travel in the spinothalamic tract and the medial lemniscus.ĭescending tracts are upper motor neurons destined to synapse on lower motor neurons in the ventral horn and intermediate horn of the spinal cord.
The ascending pathways from the body to the brain are the sensory pathways, including the spinothalamic tract for pain and temperature sensation and the dorsal column, fasciculus gracilis, and cuneatus for touch, proprioception, and pressure sensation. All information relayed from the body to the cerebrum and cerebellum and vice versa must traverse the brainstem. The brainstem has many basic functions, including regulation of heart rate, breathing, sleeping, and eating. It regulates the central nervous system (CNS) and is pivotal in maintaining consciousness and regulating the sleep cycle. The brain stem also plays an important role in the regulation of cardiac and respiratory function. This includes the corticospinal tract (motor), the posterior column-medial lemniscus pathway (fine touch, vibration sensation, and proprioception ) and the spinothalamic tract ( pain, temperature, itch, and crude touch). Though small, it is an extremely important part of the brain, as the nerve connections of the motor and sensory systems from the main part of the brain that communicate with the peripheral nervous system pass through the brainstem. The brainstem gives rise to cranial nerves 3 through 12 and provides the main motor and sensory innervation to the face and neck via the cranial nerves. In vertebrate anatomy, the brainstem is the most inferior portion of the brain, adjoining and structurally continuous with the brain and spinal cord. The brainstem regulates vital cardiac and respiratory functions and acts as a vehicle for sensory information.
