The regulation of blood glucose in a healthy person

/in /by

Select the answer that is False regarding the regulation of blood glucose in a healthy person. Glucagon signals the target cells to breakdown glycogen Glut4 transporters only allow glucose to move down its concentration gradient Glut 2 transporters only allow glucose to move down its concentration gradient the SGLT2s become saturated after a meal All the glucose that gets filtered at the kidney glomerulus gets reabsorbed through the SGLT transporters in the kidney tubule The urine threshold for glucose occurs when the SGLTs become saturated

/in /by

Which statement regarding bone is correct? a sesamoid bone is a long bone embedded in a tendon the diaphysis is covered with articular cartilage which is involved in the formation of a joint the synovial membrane of the articular capsule is directly continuous with the inner cellular layer of the periosteum a vertebra is an example of a flat bone the epiphyseal disc is not present after long bone reaches its adult length

/in /by

The rationale for treatment of heart failure can be directed to: a. Enhancing cardiac contractility. Marked out of b. Reducing the workload on the failing heart by increasing the heart rate. increasing the workload on the failing heart by decreasing the heart rate d. Reduce cardiac workload by reducing heart rate and/or enhancing the force of contraction

Hemodynamic changes seen in CHF pathogenesis

/in /by

Hemodynamic changes seen in CHF pathogenesis include the following EXCEPT for a. increased return of blood to the heart (preload) b. Increase coronary blood flow by dilating coronary arteries c. cardiac hypertrophy d. increased release of catecholamines can increase cardiac output by increasing the heart rate e.

Which of the following changes does NOT occur during atherosclerosis pathogenesis

/in /by

Which of the following changes does NOT occur during atherosclerosis pathogenesis a. Elevated macrophages will increase the formation of foam cells b. increased cytokines and growth factors production c. increased NO production d. Elevated scavenger receptors expressed on macrophages that increase the uptake of the oxidized LDL by macrophages e.

Inhibiting reuptake of norepinephrine at adrenergic nerve

/in /by

Myocardial ischemia and heart attack may arise from cocaine abuse because……. a. it increases oxygen demand (by inhibiting reuptake of norepinephrine at adrenergic nerve endings in the heart) and can increase oxygen supply by causing vasodilation b. it decreases oxygen demand (by stimulating reuptake of norepinephrine at adrenergic nerve endings in the heart) and can reduce oxygen supply by causing vasospasm

c. it increases oxygen demand (by inhibiting reuptake of norepinephrine at adrenergic nerve endings in the heart) and can reduce oxygen supply by causing vasospasm

d. it increases oxygen demand (by inhibiting the reuptake of norepinephrine at adrenergic nerve endings in the heart) and can increase oxygen supply by causing vasospasm

Characteristics of short bones

/in /by

Which statement regarding long bone is correct? The medullary canal is. lined by the periosteum the medullary canal is characteristics of short bones only spongy bone is located only in the metaphysis The epiphyseal disc lies at the junction of the metaphysis and diaphysis in growing bone the inner cellular layer of the periosteum allows for the growth of bone in width
