brain (stem) and controls automatic functions. All three of these vertebrates have two hemispheres and different lobes. Each vertebrate also has a spinal cord that descends from the brain that carries nerve impulses to and from the body along with blood vessels. All vertebrates have spinal and cranial nerves associated with the brain and spinal cord. Also many systems are needed to maintain and control features of the body. For example the endocrine‚ autonomic‚ and peripheral systems are needed

In the Lippincott Raven series “Master Techniques in Orthopaedic Surgery‚” a new title has emerged-The Spine‚ edited by David Bradford a very well known spinal surgeon. The target group is considered to be fellows‚ residents‚ students and paramedical staff. The aim is to present surgical techniques preferred by master surgeons in each subspeciality of this spe- cialty. As mentioned in the preface‚ it is

Some of the other common causes for sciatica are Spinal stenosis‚ Degenerative disc disease‚ not exercising regularly‚ Spondylolisthesis and sleeping on soft mattress. The symptoms which are associated with sciatica pain are weakness‚ itching sensation around the leg area‚ trouble in moving the foot‚ numbness

A disease of the nerve cells in the brain and spinal cord that controls voluntary muscle movement. ALS‚ Lou Gehrig’s disease‚ Amyotrophic lateral sclerosis are all names for this horrid disease. The symptoms; Difficulty breathing‚ sudden paralysis. Treatment is slim to none but there are known medications

while injuries to the spinal cord and brain do not? Bone tissues can regenerate fairly easy; in the area where the bone has been fractured‚ the bone will work to produce new cells and small blood vessels that will rebuild the bone. The new cells will cover the ends of each broken piece of bone until the gap between the bones has been closed and the bone has been repaired. However‚ like the brain‚ the spinal cord is part of the central nervous system. If the spinal cord is damaged in an accident

Present research has focused on spinal mechanisms of pain transduction. The dorsal horn comprises of multiple peptide and amino acid neurotransmitters‚ neuromodulators‚ and associated particular receptors that require the following- 1. Excitatory transmitters free from the fundamental terminals of primary afferent nociceptors; 2. Excitatory transmission amongst neurons of the spinal cord; 3. Inhibitory transmitters free by interneurons within the spinal cord; 4. Inhibitory transmitters free
