6. Which of the following statements
about the pancreas are false?
a. The pancreas consists of
islets of Langerhans.
b. The islets consists of three
cell types.
c. Alpha cells produce insulin.
d. Beta cells produce insulin.

7. The adrenal gland consists of how
many functionally distinct types of
tissue?
a. One
b. Two
c. Three
d. Four

8. The pituitary gland is controlled by
the:
a. Hypothalamus
b. Thalamus
c. Thyroid
d. Parathyroid

Expert Solution

6)

c. Alpha cells produce insulin.

Alpha cells of islet produce glucagon.Glucagon increases the glucose level in the body.
Option B is incorrect because each islets of pancreas produce mainly 3 types of cell, they are alpha cell ,beta cell and delta cell , which are responsible for secretion of pancreatic hormones.But there also produce a 4th type of cell called C cell, were function is unkown.
Option A is wrong because endocrine portion of pancreas with irregularly shaped patches is known as islets of langer hans.
Option D is wrong , because beta cells produce insulin.

7)

b. Two

Adrenal gland mainly consist of 2 type of tissue, they are steroidogenic cells of mesodermal origin and neural crest–derived catecholamine-secreting cells.Hence option A , C and D are wrong.
Center of cell is medulla , which produces adrenaline and nor adrenaline, which is released into blood stream.
Surrounding the medulla is called cortex , which produce variety of steroid hormones.

8)

a. Hypothalamus

Hypothalamus control pituitary by send messages . which is situated immediately above the pituitary gland.
Pituitary gland is called master gland because , it control several other type of hormone producing gland in the body.
Option B is wrong , because thalamus is a main sensory relay station.
Thyroid and parathyroid gland hormone help in maintaining calcium balance in the body .Hence option C and D are wrong.

Which of the following statements about receptor potentials is FALSE?

Which of the following statements about receptor potentials is FALSE? A. They are changes in the resting membrane potential of a sensory cell in response to a stimulus. B. The receptor potential spreads from the cell body of a sensory cell to the axon hillock, where action potentials can be generated C. One receptor potential always prompts the release of a neurotransmitter that induces an associated neuron to generate an action potential. D. They must be converted into action potentials...

Decide which of the following statements are True and which are False about equilibrium systems: If K = 8 for the reaction A + B ⇌ C + D, K will equal -8 for the reaction C + D ⇌ A + B For a reaction with K >> 1, the rate of the forward reaction is less than the rate of the reverse reaction at equilibrium. The value of K at constant temperature does not depend on the amounts...

Decide which of the following statements are True and which are False about equilibrium systems: The value of K at constant temperature depends on the amounts of reactants and products that are mixed together initially. For a reaction with K >> 1, the rate of the forward reaction is less than the rate of the reverse reaction at equilibrium. A large value of K means the equilibrium position lies far to the left. For the following reaction: CaCO3(s) ⇌ CaO(s)...
