Brainstem

The human nervous system is our electrical wiring of the body that transmits signals between different parts of the body. It has two components; the central nervous system and the peripheral nervous system. The nervous system is an intricate part of your body and life that 's made up of two separate systems, the brain, and spinal cord. During prenatal growth, the nervous system experiences many changes to gain its compound structure. The events of this early development include the…

Both of these tests are noninvasive, can be easily performed on infants and detect sensory hearing loss. However, A-ABR test measures the peripheral auditory system, as well as the cranial nerve and brainstem pathway, while EOAE test measures the peripheral auditory system and the outer hair cells of the cochlea. In the past, NIH has recommended ABR testing for infants who failed initial EOAE testing (NIH, 1993). While infants with positive ABR results…

activities such as eating and drinking. I believe that their hypothalamus is affected because they have an insatiable hunger for human flesh and not normal food and water. The thalamus is the “brain’s sensory switchboard, located on the top of the brainstem…” (pg.64) It helps control alertness and regulates sleep cycles. Zombies are alert and are able to sense when humans are near Yes, zombies are somewhat oblivious to their surroundings but once a human comes into their line of sight or they…

system. The neurological, or the nervous, system is our control system that regulates impulses, chemicals, and commands to the body through the Central Nervous System (CNS) or the Peripheral Nervous System (PNS). The CNS is composed of the brain, brainstem, and spinal cord while the PNS is composed of cranial and spinal nerves. The brain’s smallest unit of cells are called…

Cerebral Palsy is a disorder of the nervous system that is caused by abnormalities and damage to one or more specific areas of the brain. This damage occurs before, during, or immediately after birth when a child’s brain is developing. Research has determined what kind of brain and central nervous system damage occurs when someone has cerebral palsy as well as the symptoms that correlate with each injury and the effective treatment options to manage this chronic condition. Muscle coordination…

Jamie-Lynn Sigler. Jack Osbourne. Montell Williams. What do these three celebrities – and many Americans – have in common? They are all living with Multiple Sclerosis (MS), which is “an adult onset neurological condition in which scattered lesions in the central nervous system [CNS] produce varying combinations of motor, sensory and cognitive impairments” (Yorkston, Baylor, & Amtmann, p. 197). The symptoms depend in part on where the plaques in the CNS are located and can include optic neuritis,…

information was captivating. The brain grows in a sequential fashion meaning from the bottom (brainstem) to the top (cortex); from least complex to more complex. When the brain begins to develop it starts with the brainstem where it is found at the bottom of the skull and controls the heart rate, blood pressure, and body temperature. Next would be the midbrain which is found at the top of the brainstem and it controls motor activity, appetite, and sleep arousal responses. After the midbrain…

Maclean explains the brain is best understood by socio-cognitive context. The “triune brain” according to Maclean consists of the limbic system, neocortex, and the brainstem. Brainstem has two main functions, first it a channel for incoming sensory information and outgoing motor commands, much like the spinal cord. Second, the brainstem possesses integrative functions that are critical for cardiovascular system control, respiratory control, pain sensitivity control, alertness, and…

Movement will become more uncoordinated, speech will become more slurred and difficult to understand. The cerebellum is also connected to the cerebrum, so damage to the cerebellum may disrupt functions of other parts of the brain. Injury to the brainstem affects an individual's ability to swallow, breath, and regulate heartbeat. Some autonomic functions may be impaired. Hippocampal injury will affect mood, the ability to create and store new memories, and may cause confusion and disorientation.…

I still remember the fresh and clear day when Riley first came into our family. He was sprinting around the border of his new backyard and dashed into each room of his new home as he hunted for treats and toys to play with. But I also remember his last day before he passed away. He finished his final moments by walking around the border of his backyard, reflecting upon the joys and obstacles he faced through his life, and made his way through the house to each room, looking back upon the…
