work towards identifying ways in which Schwann cells and c-Jun could be used to repair the spinal cord‚ 4. The biomimetic polymers- This technique would use a biodegradable polymer containing a chemical group that mimics the neurotransmitter acetylcholine to spur the growth of neurites‚ and then it would guide the growth of the regenerating nerve. 5. Damaged nerves are regenerated by silencing natural growth inhibitors in neurons called PTEN and TSC1 by using genetic techniques. 6. Bone Marrow

BIOLOGY 2113 Unit IV Review Guide Chapters 13-17 Chapter 13 – True or False 1. The nervous system consists of the brain‚ spinal cord‚ and nerves. 2. The afferent nervous system consists of all outgoing motor pathways. 4. Ependymal cells engulf and destroy microbes and cellular debris in inflamed or degenerating brain tissue. 5. Oligodendrocytes form myelin sheaths around nerve fibers in the CNS. 6. Nerve fibers with many Schwann cells forming a thick myelin sheath are called myelinated fibers

cortex‚ and in the dorsal horn ganglia. Further extraneuronal locations include among others lymphocytes‚ monocytes‚ and foetal tissue. 5-HT3 receptors modulate the release of neurotransmitters and neuropeptides like dopamine‚ cholecystokinin‚ acetylcholine‚ GABA‚ substance P‚ and serotonin itself. They have been demonstrated to be involved in sensory transmission‚ regulation of autonomic functions‚ integration of the vomiting reflex‚ pain processing and control of anxiety. While the physiologic functions

Introduction and Objective The action potential is an impulse of electrical activity. Action potential occurs when a neuron sends messages electrochemically down an axon called a nerve impulse. When a neuron is not stimulated or inactive‚ it is at resting potential. When a neuron is at rest‚ the electrical charge on the inside of the neuron is negative while the electrical charge on the outside of the neuron is positive. The resting membrane potential of a neuron is about -70 mV (mV = millivolts)

Chapter 2- Neuroscience and biological foundations Glial Cells (three types): Make up about 90% of the brain’s total cells. They also supply nutrients and oxygen‚ perform clean up tasks‚ and insulate one neuron from another so that their neural messages are not scrambled. Oligodedreocytes: helps to create the myelin sheath. Purpose speed up communication in the brain. Insulate axons. Makes Neural transmissions. Microglia: Special immune cells in the brain. They can detect unhealthy and damaged
