Thyroid disease occurs normally in women but can also occur in men. A small gland just lateral of the larynx has a huge impact on the body if there is any irregularity. Many people suffer from hypothyroidism, when the thyroid doesn't work correctly, but can also suffer hyperthyroidism, when the thyroid overworks. The first is the most common that people suffer from. Blood Work is essential in order to diagnose this. I myself have been tested for it as can be heredity/genetic. My mother struggles with hypothyroidism and I can definitely can tell you some days it's really hard for her to move around and function. Signs and symptoms can range based off of the amount of hormones being overexerted or under exerted. For the most common of the two, hypothyroidism, not enough hormones are being released. The thyroid controls many things such as body temperature, maintains control in the brain, regulates your heart rhythm, and maintains basic homeostasis. When it's slowed down you may experience bradycardia, lightheadedness, constipation, sluggish feeling (fatigue), memory issues, cold intolerance, and many more symptoms. Thyroid, it is important to note, also has influence with cholesterol and cholesterol levels may rise... leading to other heart problems if left untreated. Some people may see a specialist to confirm the results and the treatment, if severe enough, include but are not limited to hormone therapy and medication for side effects.

5. Write an essay explaining how potassium chloride stops the heart.

I understand that the potassium chloride will disrupt the electrical signaling of potassium and sodium ions which maintain the heartbeat, but I need to know more of the mechanism of the process with how it does so. If you could explain. Thank you.

which muscle allows the thumb to be drawn across the palm to touch the tip of any finger?

Q7. NV is a 45-year-old Caucasian female with a history of hypertension and type 2 diabetes, and elevated LDL. She is started on atorvastatin in an attempt to control her condition. She returns to her physician complaining of muscle weakness and pain. Her creatine kinase levels are tested and found to be high. a. What is the likely cause of her symptoms? b. What genetic test might be undertaken that could explain this reaction? c. Can the prescription continue to be safely taken or should it be modified? d. What other drug might be prescribed that acts independently of the affected genetic pathway in this individual?

1. Discuss how relative time characteristics of human walking and running gaits are explained by (a) motor program-based theory and (b) dynamical systems theory.

Why does ventilation increase non-linearly (break away) with increasing intensity of

exercise?

Does exercise training affect the "ventilatory break point"?  If so, how?

1:

A) Describe isotonicity, hypertonicity, and hypotonicity. How does each affect the cell volume?

B) What is osmotic pressure? Describe a variable in the experiment which affected osmotic pressure and how it affected the osmotic pressure.

1:

a) How is active transport different from facilitated diffusion?

b) Describe the Na-K pump and the role of active transport within this pump.

1.

A) Fill in the blanks: Faciliated diffusion requires a _____________________ for a solute to be transported down its concentration gradient. This is due to ­­­­­­­­__________ or _________________ limitations

B) How do transport proteins become saturated? How does this affect the rate of facilitated diffusion?

Explain the purpose and benefits of starch, glycogen, and fiber within a healthy diet.

Case Study Organophosphate Poisoning

John has a number of prize apple trees in his backyard. To prevent them from becoming infested with insects, he sprayed them with an organophosphate insecticide. He was in a rush to spray the trees before leaving town on vacation, and he failed to pay attention to the safety precautions on the packaging. He sprayed the trees without using any skin or respiratory protection. Soon he experienced severe stomach cramps, double vision, difficulty breathing, and was diagnosed with organophosphate poisoning. While in the emergency room, his physician administered a drug, and soon many of john’s symptoms subsided.

Organophosphate insecticides exert their effects by binding to the enzyme acetylcholinesterase within synaptic clefts, rendering it ineffective. Thus, the organophosphate poison and acetylcholine “compete” for the acetylcholinesterase as the organophosphate poison increases in concentration the enzyme is less effective in degrading acetylcholine. Organophosphate poisons affect synapses in which ACh is the neurotransmitter, including skeletal muscle synapses and some smooth muscle synapses, such as the wall of the stomach, intestines, and air passageways.

Question:
Explain the spastic contractions that occurred in John’s skeletal muscles. Include the function of this enzyme in normal muscle contractions, how increases in acetylcholine and less acetylcholinesterase affects skeletal muscle, what would happen if John did not get to the hospital and why this would happen. To answer this question fully you will write at least a paragraph.

This patient’s ependymoma was located in the tapered caudal end of the spinal cord, which is supplied by branches of the aorta and spinal arteries. Ependymomas in this region are particularly vulnerable to vessel damage due to higher mobility and vascularization, and movement can lead to vessel rupture and hemorrhage, as occurs in this case. In this case, the patient suffered from a sudden onset of symptoms, presumably following hemorrhage. Answer the following questions regarding the loss of motor and sensory function observed.

Justify the patient’s sudden onset of lower limb paralysis by answering the following questions:

a. Using words and/or drawings, be sure to describe the structure of the corticospinal pathway. Identify the location of the upper and lower somatic motor neurons, decussation, and white matter tracts in the spinal cord. Then, describe how the patient’s ependymoma and subsequent hemorrhage impacted excitability of somatic neurons in this pathway.

b. Justify the patient’s paralysis in both lower limbs. Describe how changes in excitability in lower motor neurons leads to changes in excitability in a skeletal muscle fiber (cell). In your answer, be sure to briefly describe the structure and function of the neuromuscular junction (NMJ), identifying any membranebound proteins and the sequence of events required for skeletal muscle excitation and subsequent force generation. State how ependymoma hemorrhage changes graded and action potentials in a skeletal muscle fiber (cell), the concentration of intracellular calcium, and cross-bridge formation in the muscle.

please answer it ASAP, Its URGENT!!!
