Introduction Paraneoplastic neurologic syndromes (PNS) are syndromes that result from dysfunction of the nervous system, caused by a benign or malignant tumor via mechanisms other than direct tumor cell infiltration, metastasis, coagulopathy, infection or any treatment side effects [1]. All parts of the central and peripheral nervous system may be affected by PNS and, as a result, signs and symptoms are diverse. Most PNS of the central nervous system have in common a subacute course leaving the patients

Benjamin Verhey RCP 251 Guillain-Barre ́syndrome 11/14/14   Guillain-Barre ́syndrome (GBS) was first described in 1916 by Guillain, Barre ́and Strohl as a rapid progressive motor disorder with noted absence of reflexes and elevated levels of cerebrospinal fluid proteins [1]. Research throughout the early twentieth century began to identify varying subtypes and severities of GBS ranging from decreased sensory perception and distal weakness to respiratory paralysis and death in more several instances

gradually. Nerve damage is interfering with the functioning of the peripheral nervous system (PNS). Damaged nerves can occur in the brain and spinal cord and affect how the peripheral nervous system communicates with the rest of the body, it sends incorrect signals which can be a risk factor for falls. He is not a diabetic which is one of many causes of neuropathy. Neuropathy can affect the nerves that provide feeling or cause movement, if both are affected it is called sensorimotor. The nerve fibers

The nerve cells in your foot then react to the ground force and feedback the information to adjust to the force, or the appropriate muscle group. Nerve cells in your legs muscle spindles sense the position on the floor and rely the information to the brain where it is processed and send back where the movement takes place. Interfacing Biomechatronic devices allow the user to connect muscle systems and nerves in order to send and receive information from the

system is a network of neurons (nerve cells that sends information to the brain to be analyzed. Neurons live both in and outside the central nervous system. Understanding how the neurons work is vital to understanding the nervous system. The neuron has two important structures called the dendrite and axon, also called nerve fibers. The dendrites are like tentacles that sprout

targeting one of our major body functions. An example of two diseases that could affect our homeostasis within our Muscular and Nervous System are Hydrocephalus and Dystonia. The Nervous System is the system of our body that deal with the many nerves in our body that help us respond and react to things outside of our body that could or could not be conscious to us. The disease Hydrocephalus is a disease that affects the Nervous System through the brain. Hydrocephalus is when fluid that normally

cell, to produce physical and chemical reactions. Neurons or nerve cells are excitable cells. They receive, process and transmit information as electrical/chemical signals. Those signals are called Action Potentials and they have specific properties and characteristics. We wanted to gain practical experience and study some of the nerve impulse and muscle contraction behavior by stimulating an isolated sciatic nerve and a sciatic nerve/muscle from a cane toad; in a controlled environment, with the

Assignment 1 Task 1 As you exercise, changes occur in your body system known as acute and chronic effects. Acute effects on the body system contain short term effects and they would occur straightway when performing exercise. Whereas, chronic effects on the body system contain long term effects and it is adaptable to the body system so new demands are encountered within the future. There are different systems that occur in our body: musculoskeletal system, energy system, respiratory system and cardiovascular

is formed by various interconnected networks, called plexuses, of enteric neurons, glial cells, and axons (Widmaier et al. 2014). The majority of these nerve cells are found within two different arrangements of ganglia (Fig. 1): the myenteric (Auerbach’s) plexus and the submucosal (Meissner’s) plexus (Furness 2006; Guyton and Hall 2006). The nerve cells’ axons either synapse with additional neurons in the plexus or innervate the smooth muscle of digestive organs (Furness 2006). Neural activity in

Erb’s Palsy Amanda Metrikin 5/11/16 Pediatrics Erb’s palsy is a form of brachial plexus palsy. Brachial plexus palsy occurs when nerves in the brachial plexus get damaged and signals cannot travel in their normal pattern from the brain to the arm muscles. This causes paralysis (palsy) or weakness in the arm (brachial) region, as well as atrophy of the deltoid, biceps, and brachialis muscles. About two out of every 1,000 babies have this condition and it often occurs during
