Explanation:
Answer:
True
Explanation:
Catecholamines refer to the hormones produced by the adrenal gland present on the upper side of the kidney.
The catecholamine hormone includes the epinephrine, norepinephrine and the dopamine.
During stress conditions, the sympathetic division of the autonomic nervous system gets activated which leads to the release of the norepinephrine from the postganglionic neurons and the prolonged-release leads to the release of the adrenaline from the adrenal glands.
Thus, true is the correct answer.
When exercise does not increase bone mass, it has been observed that the risk of bone fractures increases due to osteoporosis.
<h3>What are the benefits of exercise to bone mass and density?</h3>
Bone mass refers to the mass of the bones in a living organism as a result of the deposition of minerals within the bone.
An increase in bone mass is directly related to the strength of the bone.
Strong bones have high bone masses whereas weak bone have low bone mass.
Physical activity have been shown to improve bone mass by increase the mass of deposited minerals in the bone.
Exercise such as walking, running, jogging, and other forms of exercise have been shown to improve bone mass and hence, the strength of bones.
However, when exercise does not increase bone mass, osteoporosis is observed which results in bone fracture.
In conclusion, the strength of a bone is directly related to the bone mass which is directly related to the mass of minerals deposited within them.

Epinephrine is also known as adrenaline. It is produced by both the adrenal glands and the certain neurons. It is used to treat some conditions like cardiac arrest, anaphylaxis and more. Its actions vary by tissue type and tissue expression of then receptors. It is binding to a variety of adrenergic receptors.It also help to increase peripheral resistance.
