the actions of an animal and transmit signals between different parts of its body. In most animals the nervous system consists of two parts‚ central and peripheral. The central nervous system of vertebrates (such as humans) contains the brain‚ spinal cord‚ and retina. The peripheral nervous system consists of sensory neurons‚ clusters of neurons called ganglia‚ and nerves connecting them to each other and to the central nervous system. These regions are all interconnected by means

curvature‚ angular kyphosis‚ kyphosis secondary to tuberculosis‚ tuberculosis of the spine‚ tuberculous spondylitis and David’s disease Anatomy: The vertebral column provides structural support for the trunk and surrounds and protects the spinal cord. The vertebral column also provides attachment points for the muscles of the back and ribs. The vertebral disks serve as shock absorbers during activities such as walking‚ running‚ and jumping. They also allow the spine to flex and extend. Pathophysiology:

surgeons perform a laparotomy (an incision across the mother’s abdomen)‚ the uterus is opened and the baby’s back is rotated into view. A pediatric neurosurgeon removes the MMC sac‚ if one is present‚ and closes skin over the defect to protect the spinal cord from exposure to the amniotic fluid. The uterus and the abdominal incision are then closed. A maternal-fetal medicine specialist performs sterile intraoperative ultrasound to map the position of the placenta and the fetus‚ and a fetal cardiologist

preganglionic neurons in the spinal cord. The presence of numerous preganglionic sympathitic neurons in the grey matter of the spinal cord produces the lateral horns. The lateral horns are just postlateral to the ventral horns that house somatic motor neurons. Parasympathetic preganglionic neurons in the sacral cord are far less abundant than the comprabale sympathetic neurons in the thoracolumbar regions‚ and lateralhorns are absent in the sacral regionof the spinal cord. 4.

I was walking down the trail to Sombrio Beach which is about a 1.5k hike down a steep trail to the ocean. I had a surfboard under my right arm‚ an axe in my left hand‚ and a large 40 litre hiking backpack fully loaded with supplies on my back. About half way down there is a left turn in the trail which has a declining

LEVELS OF ORGANIZATION OF NERVOURS SYSTEM: NEURONS: * STRUCTURE AND FUNCTION: Specialized cell transmitting nerve impulses; a nerve cell. Neurons have specialized projections called dendrites and axons. Dendrites bring information to the cell body and axons take information away from the cell body. Neurons communicate with each other through an electrochemical process. Information is transmitted to the receiving cell at junctions via chemical messengers called neurotransmitters. At this juncture

The Biology of Mind Neuron Communication Neuron is a nerve cell‚ basic building block our nerve system Neurons consists in: Dendrites : neurons bushy branches and it listens Axons: Tube that passes the messages and it speaks – transmit Action potential : is a neural impulse‚ brief electrical charge that travels down an axon. Threshold: is the level of stimulation required to trigger a neural impulse Myelin Sheath covers an axon and some neurons Synapse : is the junction

transmitting signals between different parts of the body and the brain. Key Components: Central Nervous System (CNS): Brain: The control center of the body‚ responsible for processing sensory information‚ making decisions‚ and coordinating movement. Spinal Cord: A long‚ tube-like structure that extends from the brain down through the spine. It transmits messages between the brain and the rest of the body. Peripheral Nervous System (PNS): Nerves are pathways that connect the CNS to the body’s limbs and

The Central Nervous System is composed of the brain and the spinal cord and one of it’s primary functions is to send out messsages to the rest of the body. One chronic illness that affects the Central Nervous System is Multiple Sclerosis. Roughly 2 million people througout the world have been faced with this disease‚ and “in the United States‚ it is estimated that 450‚000 people are affected‚ with 10‚000 new cases per year” (Goodman & Fuller 772). This disabiling condition has been found more prevelant

Alexander (2008)‚ “Spina bifida is a birth defect that involves the incomplete development of the spinal cord or its coverings. The term spina bifida comes from Latin and literally means "split in two" or "open" spine”. The location of the opening on the spine often dictates what problems may occur and how bad they will be. It is important to know that Spina bifida can affect the nerves‚ surrounding spinal bones‚ muscles‚ and the overlying skin. According to the National Institute of Neurological
