1. Compare atrial and ventricular systole and diastole

• In common usage, how does the definition of a nerve differ from its physiological definition?

what are the external and internal features of the medulla?

what is the regional supply of the medulla

which specific trait/ nuclei are likely to be affected when blood supply to the lateral and medial part of the medulla is interrupted

If a patient complains of the following

a) loss of pain sensation over the right half of the face

b) loss of taste on the right half of the tongue

c) difficulty in hearing

Determine the structures involved and locate the lesion

Choose one of the major sensory systems (smell, taste, vision, hearing, balance, or touch) and explain in detail how a sensory stimulus is transduced into an action potential.

The hypothalamus and the primary motor cortex are the two parts of the brain that have the most direct influence over the body. Compare the ways in which each creates changes in the body and the types of function they are involved in.

You trip and fall and a scalpel ends up between your ribs and breathing becomes difficult. What has happened? How can it be fixed?

After your discharge from the hospital you go out for a nice dinner to celebrate. Puffer fish is on the menu. Turns out your previous patient is the chef and is less than motivated to carefully prepare your dinner. You end up with TTX poisoning. TTX blocks voltage gated sodium channels. How would this affect the firing of action potentials? Untreated, TTX poisoning is fatal due to asphyxiation. How? Would your death be quicker or slower at a high altitude? Why?

You accidentally remove the adrenal glands. The patient now doesn’t produce aldosterone. What affect will this have on the kidneys? What effect on hydration? What effect on blood pressure? Tell me one other system that will be drastically altered by a lack of adrenal glands.

Next, the patient begins to hyperventilate, what will happen to plasma pH? How might a paper bag help correct this? What will the kidneys do to compensate?
You hand them a pill of unknown origin. After they’ve taken it, you discover that it’s a poison, which is filtered and secreted in the nephron, but not reabsorbed. Is this better or worse than something that is reabsorbed? Explain.

Q2)

what is the physiological significance of the skeletal muscle fiber triad relationship?

2. The t-tubules bring calcium to the sarcoplasmic reticulum.
3. The terminal cisternae subdivide the sarcolemma.
4. The sarcoplasmic reticulum transfer calcium to the t-tubules.

2. Adenylate cyclase is activated
3. G protein dissociates from the NE receptor

5. Cyclic AMP induces several effects in the cell

Q4)  ____ is the only sense in which signals can reach the cerebral cortex through second order sensory neurons.

1. Equilibrium
2. Vision
3. Touch
4. Smell
5. Taste

1. The A-bands get smaller
2. The H zone becomes more obvious
3. The Z-discs get pulled away from the A bands
4. The I-bands get smaller
5. None of these

Group of answer choices

It would cause more calcium to be released fron the sarcoplasmic reticulum

It would increase the amount of ACh in the synapse

It would decrease the amount of ACH in the synapse

It would increase parasympathetic output

It would increase sympathetic output

It would decrease parasympathetic output

It would decrease sympathetic output

It would have influence on autonomic output

_____ stimulates release of aldosterone and antidiuretic hormone, which decrease water excretion

A) Renin

B)angiotensin II

explain what a forensic anthropologist does, how are they able to establish the biological profile, what else are they able to tell about an individual from the skeleton?

This is one of the questions and answers to one of my scholarship questions, I want help to review/edit/add to make it sound better please!

1. What is your most meaningful achievement, and how does it relate to your field of study and your future goals?

The most meaningful achievement I have faced was beating cancer in March 2016 during my senior year of high school. This experience changed my view on many aspects of my life. Being in the hospital for so many hours while being cared for by such amazing nurses made me want to be someone that can help others. I have gained a strong love andempathetic side for everyone, I want to help people and give them the hope of a second chance. During this life experience, I started to acknowledge how important my health is, not only with incorporating exercise but with eating nutritious food.

From then on, I started to gain a passion for nutrition. The medical setting is where I wanted to be. My goal is to one day be able to help children live a healthier life and give them the hope and love they need.

Question 1

In this movement disorder, excessive or inappropriate contraction of muscles (often agonists and antagonists) leads to sustained abnormal postures of the affected region of the body.

3. athetosis
4. asterixis
