1. In which compartment you would find a low concentration of both K+ ions and Proteins and why?

2.  In a given molecule which are the determinants for its transport through a membrane (active/passive/receptor mediated etc.) ?

What happens when you are on an airplane and you feel your ears start to “pop” or have a plugged-up feeling that is somewhat relieved when you swallow? Why does this feeling of the eardrum occur, and why does swallowing relieve the symptoms?

Think about the microscopic, histological physical traits that are unique to skeletal muscle. In complete sentences, explain how these microscopic, histological physical traits are a reflection of the functions of the cardiac muscle tissue.

Describe the smooth muscle layers in the wall of the esophagus, stomach, small intestine & large intestine; include the number of layers and layer arrangement & how this is functionally important

b) stronger muscle contractions occur but stronger action potentials do not uoccur
c) a second action potential occurs in the muscle fiber, before the first action potential is finished
d) both a and b are correct
e) all of the above are correct

Q3. The force generated by a single muscle fiber:

Select one:

A.Cytosolic ATP levels rise

B.Cytosolic Ca2+ levels rise

C.Membrane depoarization

D.insulin secretory vesicles fuse with the plasma membrane

E.K+ channel closes

F.glucose enters the cell

1. List the major structural differences between a generalized cell and the modifications that are found in a muscle cell.

2. Describe how lactic acid fermentation differs form aerobic respiration, including the amount of ATP energy is produced in each.

3. Explain how the mechanism of striated muscle contraction differs from smooth muscle contraction.

Explain the relationship among chylomicrons, cholesterol, and the lipoproteins LDL. What is the role of this lipoprotein in the body? Why is it considered “bad”? Where does it come from? Where could it end up?

spirometry  

describe the differents devises how to use them , what are the formula and the important of these formula.

talk about the physiology and definition of the formula

A 155 lb., 60-year-old man had a chronic productive cough, exertional dyspnea, mild cyanosis, and marked slowing of forced expiration. His pulmonary function and laboratory tests follow: Frequency 15 breaths/min Alveolar ventilation 4.1 L/min Vital capacity (VC) 2.2 L Functional residual capacity (FRC) 4.0 L Total lung capacity (TLC) 5.2 L Maximum inspiratory flow rate 252 L/min Maximum expiratory flow rate 21 L/min PaO2 63 mm Hg PaCO2 38 mm Hg Pulmonary function tests after bronchodilator therapy: Frequency 15 breaths/min Alveolar ventilation 4.25 L/min VC 2.4 L FRC 4.0 L TLC 5.2 L Maximum inspiratory flow rate 252 L/min Maximum expiratory flow rate 24 L/min PaO2 63 mm Hg PaCO2 37 mm Hg

6. What is the cause of this altered RV?

7. Calculate the tidal volume (TV) for this person before and after the bronchodilator therapy. TV = AV/f + patient body weight. Hint: TV is calculated in mL, so you will need to convert L to mL before completing the equation.

8. Is each TV normal or altered?

9. Calculate the minute ventilation (MV) for this person before and after the bronchodilator therapy. MV = TV × f

10. Is each MV normal or altered?

. Every textbook on brain behaviour relationships has one or another version of the famous motor ‘homunculus’ – the distorted body part graphic drawn juxtaposed to the primary motor cortex. The motor homunculus is based on Penfield’s groundbreaking work showing that the amount of cortical area affecting movement of a given body part was not related to the body part’s size but to its motor control capability (thus the grotesquely enlarged appearance of the homunculus’ lips and hands). Penfield used short-duration electrical pulses in the posterior region of the frontal lobe that elicited, simple, nearly reflexive, twitch-like movements. Had his electrical stimulation been of much longer-duration, what type of movements would he have likely elicited from there?

Compare and contrast inflammatory and neuropathic pain.

1. In a tabular form, differentiate between the superior mesenteric artery and the inferior mesenteric artery.
2. Compare between the pelvic diaphragm and the thoracic diaphragm.
3. List any five specific areas of the body where neural block can be applied, with reference to the nerve targeted.
4. In a tabular form, compare between the pubis symphysis and the Sacro-iliac joint (position, formation, components, types of cartilage, clinical note).
5. In a tabular form, List the bony landmarks and ligaments of the pelvic girdle proper per piece of bone (ilium, ischium, pubis).
6. Differentiate between the anococcygeal body and the perineal body.
7. List out the components of the male genital organs (internal and external).
8. List out the components of the female genital organs (internal and external, and ligaments around the uterus).

Can someone do all questions pliz in detail. Question number 3 is where I face great difficulty. Please if someone can help me with all 8 questions. I posted this questions before but noone answered. Please help me.

Compare and contrast the effects of right hemisphere vs. left hemisphere damage on Intelligence as measured by the Weschler Adult Intelligence Scale (WAIS).
