down with their legs hanging off the chair. We can take a tendon hammer and apply pressure to the patellar tendon by striking it. The strike will stimulate sensory neurons which will send a signal to the central nervous system, which is the brain and spinal cord. At the central nervous system the sensory neuron makes a synaptic connection to a motor neuron. The motor neuron will send the signal to stimulate the quadriceps to contract which causes the leg to be extended. The connection of the sensory

The most common is age, on the NHS website it states the likelihood of an individual developing Alzheimer’s doubles every five years.

Parkinson’s disease Parkinson’s is a disease that affects the nervous system. Parkinson’s is caused by the progressive impairment or deterioration of neurons in the brain known as the substantia nigra. The brain produces a chemical called dopamine. Dopamine works as a chemical messenger in the brain allowing communication between the substania nigra and the corpus striatum. The communication works by coordinating smooth and balancing muscle movement. When there is a lack of dopamine it results

Jamecia Rogers Professor Benham ENC 1101 October 4,2011 Effect of Multiple Sclerosis Multiple Sclerosis is an autoimmune condition of the nervous system and the brain. This means that the body’s innate ability to attack potentially harmful foreign bodies backfires. When this happens, the immune cells that should target the pathogens attach normal and healthy cells instead. Multiple sclerosis is such a condition in which the nerve endings are damaged due to the loss or destruction of the

desirable to constantly be in an emergency mode as the mind and body would have to ultimately pay the price. Stress is a normal physical response to events that make us feel threatened or upset our balance in some way. When a threat is perceived, our nervous system responds by release a flood of stress hormones, including adrenaline and cortisol. These hormones rouse the body for emergency action. As a result, our heart pounds faster, muscles tighten, blood pressure rises, breath quickens, and senses become
