Charcot-Marie-Tooth Disease is the first disease on my list it is known as hereditary motor and sensory neuropathy or peroneal muscular atrophy. The peripheral never is outside of the brain and spinal cord and it supplies the muscles and sensory organs in the legs and arms. The way I would basically explain to a patient that this disease will challenge his or her gait. There is no cure of this disease but physical and occupational therapy will help with walking‚ leg braces may be an option

Mad Cow Disease Paper Mad Cow Disease‚ or bovine spongiform encephalopathy (BSE)‚ is a fatal brain disorder disease of cattle that affect the central nervous system and causes staggering and agitation. Some unknown transmissible agent causes mad Cow Disease. Currently‚ the most accepted theory is that the agent is a modified form of a normal cell surface component known as prion protein. In BSE‚ the unknown agent causes the cow ’s brain cells to die‚ forming sponge-like holes in the brain.

body is located in the lateral horn of the spinal cord. The parasympathetic nervous system is characterized by short postganglionic axons near the organs they innervate. The sympathetic and parasympathetic divisions of the ANS differ in the length of the preganglionic and postganglionic axons‚ location of the preganglionic cell bodies‚ and position of the ganglia where preganglionic and postganglionic neurons synapse. Sympathetic fibers leave the spinal cord in the thoracic and lumbar regions. Axons

The Muscular System: Contraction of Motor Units 1. Define a motor neuron:_____A single nerve cell that branches from the brain or the spinal cord to a muscle or a gland. 2. Define a motor unit: ___A motor neuron and all of the muscle fibers it stimulates. 3. The synapse between a motor neuron and the muscle it innervates is called a ____neuromuscular junction_______. 4. The stimulation of additional motor units will increase the strength of the contraction. This process is called

Types of flexion: cranial flexion‚ cervical flexion‚ pontine flexure‚ dorsal flexure‚ caudal flexure. ^Cervical flexure- ventral bend in embryo at transition between myelencephalon and spinal cord ^Dosal Flexure- a ventral bend in the midbody making the back confex ^Pontine flexure- a ventral bend in the head region between the metencephalon and the myelencephalon. Visible in 120 hour chick embryo (5 day). ^cranial flexure- ventral bend
