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).

it is for my kinesiology class discussion

Prolonged exposure to stressful conditions and events results in the continuous production of increased levels of hydrocortisone (cortisol) which, in turn, has differing functional effects upon two limbic structures. a) Name these limbic structures and b) explain how chronic exposure to cortisol differently affects each.

The term ‘innervation ratio’ refers to the average number of muscle fibres that

are innervated by a single motor neuron. Describe the relationship between this ratio and the body’s skeletal muscles.
