time; the reason could be that when you had to hear the sound for the voluntary activation you had to process the sound than process kicking. This would take longer than automatically kicking with the involuntary activation. In the body an impulse nerve signal had to be sent to the object reacting in this case kicking your leg. 2. How does your reaction time to the voluntary action of your quadriceps compare with your reaction time to the simple reaction task in Project 2.2.3? The task in this lab

axillary arteries had to be reattached. Bicep and tricep muscle tissues and the humorous bone also had to be reattached. 3. What organ system was most likely not reattached? Explain. The nervous system‚ severed nerves cannot be reattached the same way; the severed nerves will not be useful again. 4. Why was a clean bite so important? The bite did not tear much tissue‚ making reattaching the arm possible. 5. Why was the bone shortened? In order to insert the plate‚ they

Introduction to Parkinson’s disease Parkinson’s disease is a chronic progressive movement disorder. It happens when nerve cells in the brain don’t produce enough of a brain chemical called dopamine. Parkinson’s disease was founded by a doctor in London in1817 name James Parkinson. He wrote a book called the “shaking palsy” that he researched in his neighborhood to find out where the disease came from Weintraub‚ D.

Blurred vision and eyes strain could have to do with the optic nerve‚ headache‚ soreness and fatigue. 3. In the spinal cord there are nerves that are in charge of these involuntary functions. There is also the medullary rhythmicity centers in the medulla oblongata that adjusts the rate of breathing. These could be possibilities that Annies is having

Blood vessels and arteries. The brachial and ulnar collateral arteries‚ the Axillary‚ brachial‚ basalic‚ Median cubital‚ radial blood vessels. 3. What organ system was most likely not reattached? Explain. The nervous system would not reattach because nerve cells do not go through mitosis so they won’t grow back and reattach to each other. 4. Why was a clean bite so important? By it being a clean bite it was easier to attach the arm back on. There weren’t a lot of tissues that was shredded. 5. Why

Drugs and the nervous system Neurotransmitters within the body include excitatory and inhibitory‚ noradrenalin‚ dopamine‚ serotonin; acetylcholine and glutamate are examples of excitatory neurotransmitters. GABA and glycine are examples of inhibitory neurotransmitters. General anaesthetics General anaesthetics act mainly on the central nervous system to stop information processing; these may be given by inhalation or intravenously. Nitrous oxide or laughing gas is used in maintain anaesthesia

cartilage‚ and bone. Nervous tissue forms the nervous system‚ which is responsible for coordinating the activities and movements of your body through its network of nerves. Parts of the nervous system include the brain‚ spinal cord‚ and nerves that branch off of those two key parts. Nervous tissue consists of two kinds of nerve cells: Neurons are the basic structural unit of the nervous system. Each cell consists of the cell body‚ dendrites‚ and axon. Neuroglia‚ or glial cells‚ provide support

spina bifida‚ the nerve tissue that is injured or missing cannot be restored or substituted‚ nor can function be restored to the damaged nerves. Depending on the type and severity of the disorder‚ treatment will be available for less severe cases. Mild cases in children generally don’t require treatment‚ but they may need surgery as they grow. The first priority is to prevent any infection forming in the exposed nerves and tissue from the spine defect‚ and to protect the exposed nerves and structures
