Pancreatic Glands

Question 1

Types of pancreatic glands

Answer 1

• exocrine

- endocrine

Question 2

Pancreatic endocrine hormones

Answer 2

-function relate to glucose levels
-secreted from pancreatic islets (islets of Langerhans), antagonistic
> alpha cells secrete glucagon
> beta cells secrete insulin

Question 3

Glucagon

Answer 3

• increase blood glucose levels
• targets liver cells, by promoting glycogen breakdown, gluconeogenesis, glucose release
• secreted by low glucose level trigger (and SNS activity, ex) fight or flight situation))

Question 4

Insulin

Answer 4

-decreases blood glucose levels
> promotes glucose uptake, glycosis, glycogen synthesis
> inhibits glycogen breakdown, gluconeogenesis
> stimulated by high glucose levels (inhibited by the SNS)

Question 5

Diabetes

Answer 5

-lack in insulin activity (Type I, type II)
-symptoms:
> polyuria (frequent urination)
> polydispia (frequent thirst)
> polyphagia (frequent hunger)

Question 6

Type I diabetes

Answer 6

• insulin not being produced

- autoimmune disease

Question 7

Type II diabetes

Answer 7

• cells no longer sensitive to insulin

- change in receptors, it no longer is able of taking up glucose
