Central Core of the Brain
Kali Goesonon 27 September 2012
Transcript of Central Core of the Brain
- 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.
