a.Which type of vertebral bone has two transverse foramen?

b.Name the vertebral space the spinal cord travels through.

c.Which part of the vertebrae do the ribs articulate with?

d. Which material connects 10 of the ribs to the sternum?

e. What is the difference between true, false, and floating ribs? Give their numbers

Explain the initiation and regulation of labor contraction including all organs and hormones (and hormone-like molecules) that participate in the process. Describe the positive feedback mechanism of labor contractions. Why do you think the slow intravenous injection of synthetic oxytocin (Pitocin®) can be used to induce parturition (childbirth)? After childbirth, pituitary-derived oxytocin also triggers milk ejection. What is the initial stimulus for the secretion of oxytocin? What is the target cell type of oxytocin in the mammary gland? For parturition, which layer of the uterus does this hormone act on?

1. What are some ways your body regulates the increase of body temperature that also occurs when exercising? Do you think your internal body temperature responded in the same way as your external skin body temperature? Explain.

discuss lungs volumes and capacities

1. The total volume of air in Jeffrey’s lungs is 5800 mL. If his inspiratory capacity is 3200 and his residual volume is 1000, what is his ERV and FRC?

2. TLC = 4200, VC = 3200, IC = 2000, What is the FRC and RV?

3. VC = 3200, IC = 2200, ERV= 1000, RV = 1000, what is TLC?

The total volume of air Sally can inhale is 3400 mL after a quiet exhalation. When Sally is sitting still she breaths 400 mL and there’s 2200 mL of air leftover in her lungs. Calculate or figure out the following values: TV, TLC, IC, FRC, IRV

5. When at rest, Jeremy inspires and expires 600 mL. While his lungs can fit 7000mL of air, only 5500 can move in and out, if he really really tries. Normally, there’s 3400 mL of air left in his lungs after a quiet exhalation. Calculate or figure out ERV, TV, TLC, IC, FRC, IRV, RV

(1) When engaged in involuntary breathing, which of the following volumes enter and/or exit the lungs? ERV, IRV, TV, VC. Which ones are always voluntary?

18. Saltatory conduction is made possible by ________.

    a. the myelin sheath b. large nerve fibers c. diphasic impulses d. erratic transmission of nerve impulses

19. The synaptic vesicles release the neurotransmitter Ach into the synaptic cleft via

5. The Na/K voltage gated channel protein uses __________ to move sodium and potassium across the plasma membrane.

6. The ion, which conduct electricity, is:

a. A charged atom b. a charged molecule c. Both A and B are correct d. none of these are correct

7. In a resting membrane potential, the inside of a cell is ____________, and the cell exterior is _____________.

8. The resting membrane potential, if measured by a voltmeter is ________mV.

9. The area of the neuron that receives the stimulus is ______________.

10. The area of the neuron that transmits the impulse is __________.

11. The dendrite and cell body of the neuron contains the following protein

A. Neurotransmitter receptor B. sodium channel C. Na/K pump D.. all of the above

1. How is the contraction of a skeletal muscle cell different than the contraction of a smooth muscle cell? How does this aid in each muscle cell's function? 2. What is the purpose of myoglobin in slow-twitch muscle fibers? Why is there more myoglobin in slow-twitch muscle fibers than in fast-twitch fibers? 3. What is the purpose of gap junctions in cardiac muscle cells and some smooth muscle cells?

what is the difference between sheep ureter vs human ureter

1. Diagram how the respiratory system and the renal system compensate in the body to maintain blood pH.
2. Complete this Case Study: Bob is a 64-year-old male admitted to the emergency room for asthma. His laboratory results are as follows: pH 7.31, pCO₂ higher than normal, and total HCO₃^– also higher than normal. Classify his acid-base balance as acidosis or alkalosis, and as metabolic or respiratory. Is there evidence of compensation? Propose the mechanism by which asthma contributed to the lab results seen.*
3. Complete this Case Study: Kim is a 38-year-old women admitted to the hospital for bulimia. Her laboratory results are as follows: pH 7.48, pCO₂ in the normal range, and total HCO₃^– higher than normal. Classify her acid-base balance as acidosis or alkalosis, and as metabolic or respiratory. Is there evidence of compensation? Propose the mechanism by which bulimia contributed to the lab results seen.*
