Transcript of Central Core of the Brain

Central Core Body Parts Controlled by the Central Core Diseases of the Central Core How the Central Brain Functions Vocabulary Questions Traumatic Brain Injuries (TBI) Central Core controls life processes including breathing, pulse, arousal, movement, balance, sleeping and early stages of processing sensory information. Disease are caused by lack of oxygen to the body. Causing cells to become cancerous, brain tumors and abnormal growth in cells. Central Control for Life/ Fore brain Every 15 seconds, someone in the United States suffers a traumatic brain injury. Of the 1,000,000 people treated in the hospital emergency rooms each year, 50,000 die and 80,000 become permanently disabled. Brain injuries occur more frequently then breast cancer or AIDs. -The Central Core is found in all vertebrates. It's 5 main regions help regulate basic life processes, including breathing, pulse, arousal, movement, balance, sleep and the early stages of processing sensory information.
- Medulla is the center for breathing, waking, sleeping and the beating of the heart.
-Pons trigger dreaming and waking from sleep.
- Reticular Formation signals the cerebral cortex to attend to new stimulation and to remain alert even during sleep.
-Thalamus begins the process of interpreting sensory information. It determines fundamental properties, such as; whether something is good or bad, and then fowards the information to the appropriate are of the cerebral cortex, where the information processing continues.
- Cerebellum coordinates body movements, controls posture, and maintains equilibrium.
-Hindbrain Functions collectively to coordinate motor activity. What part of the central core controls sleep?
What does the medulla do? Metastatic Brain Cancer-
made of cancerous cells else where in the body, cells spread to the brain causing tumors. Exact cause of brain cancer
unknown but some factors are genetics, environmental toxins, radiation, and cigarette smoking are all linked to brain cancers. Damage to the Cerebellum
- loss of coordination of motor movement (asynergia)
- inability to judge distance and when to stop (dysmentria)
- inability to preform rapid alternating movements ( adiadodchokinsia)
- movement tremors (intention tremor)
- staggering, wide based walking ( ataxic gait)
- tendency toward falling
- weak muscles (hypotonia)
- slurred speach ( ataxic dysarthria)
- abnormal eye movement (nystagmus) The central core consists of the thalamus, pons cerebellum, reticular formation and medulla. These five central regions are the central areas that regulate breathing, pulse, arousal, sleep and early stages of processing sensory information. The thalamus interprets the sensory information and helps determine what is good and bad. It then sends messages across the cerebral cortex to the region where further analysis of the information continues. The area that helps you dream and wake you up from sleep is the pons. The body coordination and control of posture and maintenance of the equilibrium is taken care by the cerebellum. The signals sent to the cerebral cortex that help in attending stimulation and remain alert while sleeping is taken care of by the pons. Last but not least, the medulla helps you breath walk sleep and singal the heart to continue breathting.
