Through this‚ we can delve deeper by understanding how nerves‚ through the actions Of various neurotransmitters affect the motility of the gastrointesital tract. Furthermore‚ we can investigate The effects of drugs‚ and their uses in replicating effects of autonomic neurotransmitters as well as The way certain drugs can interfere with autonomic neurotransmitters and how they interact with Their target tissues.

No summation 9. Why is it important that summation not occur in heart muscle? Summation would increase the Heart muscle contractions which would lead to heart attack. Activity 2: Vagus Nerve Stimulation 1. Describe the effect of the vagus nerve stimulation on the heartbeat. The vagus nerve stimulation caused the heartbeat to flatline and then restart and react normally 2. Soon after you applied the stimuli‚ did the heart rate increase or decrease? Soon after the stimulation is

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

This is a collection of disorders that occurs when nerves of the peripheral nervous system are damaged. This is located near the nervous system outside of the brain and spinal cord. Neuropathy causes many things such as pain and numbness in the hands and feet. But this results from traumatic injuries‚ infections‚ metabolic disorders‚ and exposure to toxic. Diabetes is the most common causes of neuropathy. Having this disorder can affect nerves that control the muscle movement; it can also affect

Neurons: The Basic Elements of Behavior Neurons‚ or otherwise called nerve cells‚ are the basic elements of our nervous systems. We have as many as one trillion nerve cells throughout our bodies. These cells are responsible for controlling our behavior. So what is a neuron? “A neuron is a nerve cell that is the basic building block of the nervous system. Neurons are similar to other cells in the human body in a number of ways‚ but there is one key difference between neurons and other cells

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
