Anatomy and physiology of the brain and spinal cord The brain is a spongy organ made up of nerve and supportive tissues. It is located in the head and is protected by a bony covering called the skull. The base‚ or lower part‚ of the brain is connected to the spinal cord. Together‚ the brain and spinal cord are known as the central nervous system (CNS). The spinal cord contains nerves that send information to and from the brain. The CNS works with the peripheral nervous system (PNS). The PNS

Sacral hiatus is th th formed because of incomplete 5 and sometime 4 sacral laminae. A typical vertebra consists of a rounded body anteriorly and a vertebral arch posteriorly (arch consists of two pedicles and two laminae). The vertebral arch encloses the vertebral canal through which the spinal cord

Spina Bifida is a congenital defect of the spine in which part of the spinal cord and its meninges are exposed through a gap in the backbone. This syndrome was discovered over four hundred years ago. The most common type of Spina Bifida is Myelomeningocele. The neural tube defect which the spine not forming completely‚ results in a spinal canal that is incomplete. Myelomeningocele is a birth defect in which the backbone and spinal canal doesn’t close before birth. I will create my center based

Spinal Tap A spinal tap involves taking a small amount of fluid from your spine in your lower back. This fluid is called cerebrospinal fluid. Your cerebrospinal fluid is then tested to detect protein levels. People with Guillain-Barre typically have higher-than-normal

Central Nervous System: The central nervous system consists of the brain and spinal cord. The brain controls bodily functions. The cerebrum is the largest part of the brain in humans. The cerebrum is the last place that information travels through in the brain. The spinal cord is the part of the body that communicates between the brain and the nerves that connect to the spinal cord. The spinal cord is commonly known as a pathway from the brain to the body. Peripheral Nervous System: The peripheral

brain. Along with an MRI scan‚ a CT scan can help diagnose hydrocephalus in both pediatrics and adults. Both of these imaging modalities can diagnose and show the enlarged brain along with the dilated ventricles that results from excessive cerebral spinal fluid within the brain. If there is a case of hydrocephalus with the patient‚ there is a plan and a way to treat it. Fortunate enough‚ a prognosis can be done.
