Back muscles.

Answer each of the following: a. An accident victim was not wearing a seat belt and was thrown from his car. He was pronounced dead at the scene. An autopsy revealed the cause of death was a spinal cord injury resulting in paralysis of the phrenic and intercostal nerves. Why was this injury fatal? Include an explanation of the

Creatine Kinase: Effect on Muscles

What would occur to muscle function if a disease caused a malfunction in the enzyme creatine kinase? Include in your response the function of creatine kinase and the cellular events that would be most compromised by the loss of this enzyme. Be specific.

Muscle Contraction Detailed Description

Describe in detail a muscle contraction and relaxation from the point of the nervous stimuli. Describe all cellular structures and physiological events that occur at the cellular and tissue level that are directly involved with the muscle contraction (receptors, etc.). I am referring to skeletal muscle (like contraction of a bi

Disease of the areolar connective tissue.

If a disorder existed that affected areolar connective tissue, what organ structures and functions would be affected? Include at least two examples. Also include a description of the types of fibers and cells found within areolar tissue. Be detailed.

Classification of Joints

How are joints classified? Explain the classification of joints based on structural and functional characteristics.

Anatomy and Physiology of Synovial Joints

Describe the structure and function of the following structures or tissues in relation to a synovial joint: Ligament, tendon, articular cartilage, synovial membrane, bursa.

Anatomy and Physiology of Bones

Which category of bones (long, short, flat, irregular) has the least amount of spongy bone relative to its total volume? What type of bone is the phalanx classified as? What two types of bone are the major submembranous site of osteoclasts? What type of bone is the major submembranous site of osteoblasts? What is th

Heirarchy of anatomical organization of the kidneys

I need to correlate the microscopic sturctures (cells) to the gross stuctures of the kidneys. I need to integrate into the response the heirarchy of anatomical organization from the cellular level to the organ level of the kidneys. Also, describe how the function of the kidneys correlates to the anatomical structures described

Case Study: Neck Injuries and Partial Paralysis of Limbs

A 22 year old woman was in a motor accident with resultant neck injuries that led to partial paralysis of the upper and lower limbs. Sher reports that almost immediately after her chest felt heavy. Doctors in the ER observed that she was dyspneic. Her pulmonary function values were: vital capacity 650 ml min vent vol-6L/min

Physiology case study

I am given this info: My comments are in brackets A 26 year-old female prisoner begins a hunger strike to protest what she considers unfair prison policies. She drinks only tap water, and her only exercise is two dailyt half hour walks at approx 2.5 mph. The temp in her cell is kept at 72F. her starting weight is 70 kg (154 lb

Knee joints

Predict the consequences of of limiting movement at the knee joint. Based on my reading, I'm confused as to whther the various knee injuries and disorders associated wih the knee are examples of such consequences. Please help!!!

Need help with two questions.

You have just been in an accident and have experienced substantial blood loss. What autoregulatory mechanisms in the kidney will be initiated to maintain filtration pressure? Describe this mechanism in detail. If blood loss continues, what will occur to the autoregulatory mechanism? Given the following lab values, answer the

Goldman equation is explored.

The question asks: Calc. the membrane potential from Goldman equation using pNa/pK = 0.02 & the conc. of Na & K inside & outside the cell. Calc. the membrane potential using pNa/pK = 20. Compare these calculated values of membrane potential with the numbers from the simulation. Why does the membrane potential shift when pNa/

Describe the four basic layers of the digestive track; Liver failure

A lab worker accidently spills a tray of slides you have just prepared of the length of the digestive tract, beginning with the esophagus and ending at the rectum. How would you know that the first slide you picked up off the floor and checked with the microscope was from the stomach? Describe the four basic layers of the digest

Compare and contrast the composition of blood plasma and glomerular filtrate

Compare and contrast the composition of blood plasma and glomerular filtrate. Your friend is in a car accident and experiences a substantial amount of blood loss. The emergency room doctor tells you he is sending your friend to surgery to stop the bleeding however she is at a high risk for kidney failure. What does this mean? W

Homeostasis: About the level of urine passed from a human

A human drinks 1000 CM3 of distilled water and measures the amount of urine passed at 30 minute intervals. The subject passes 175CM3 at 30 mins, 325CM3 at 60 mins, and 225 CM3 at 90 mins. Why does the subject pass more urine at 60 mins than 90 mins???

Blood types/hemagglutination assay

Hi. Can someone please help me with the following blood typing/hemagglutination assay problem. I'm confused about who is the donor and who is the acceptor.

Flow cytometry

Hi. Can someone please check my answers to the following multi-part question, and explain the questions I couldn't answer or that I got wrong? This is an 11-part question (!), but I think it looks worse than it is. It's 60% of a 1-hour test, so I don't think it should take more than an hour to go through, at most. For the

Monoclonal Antibodies and Growth Environment

Monoclonal antibodies come from clones of B cells that produce a single antibody of known specificity. B cells will nor normally divide in the absence of antibody. The special trick that allowed monoclonal antibody-producing cells to be grown in culture was: (a) Mice were immunized with antigen and T cells removed and grown
