All of the following are functions of adrenaline except :-a)Increases ...
Adrenaline is a hormone secreted by the adrenal glands in response to stress or danger. It plays an important role in the fight or flight response. Some of the functions of adrenaline are:
Increases blood supply in skeletal muscle:
Adrenaline causes the blood vessels in the skeletal muscles to dilate, which increases blood flow to the muscles. This helps to provide more oxygen and nutrients to the muscles during physical activity.
Hyperglycaemia:
Adrenaline stimulates the liver to break down glycogen into glucose and release it into the bloodstream. This increases the blood glucose level, which provides extra energy to the body during times of stress.
Tachycardia:
Adrenaline increases the heart rate and the force of contraction of the heart muscle. This helps to pump more blood to the muscles and other organs that need it during physical activity.
Uterine relaxation:
Contrary to the other functions, adrenaline does not cause uterine relaxation. In fact, it causes the opposite effect by constricting the blood vessels in the uterus, which reduces blood flow to the uterus and can cause contractions. This is why adrenaline is not used to induce labor or to stop uterine contractions.
In summary, adrenaline increases blood supply to skeletal muscle, causes hyperglycaemia, and tachycardia, but does not cause uterine relaxation.

All of the following are functions of adrenaline except :-a)Increases ...
Adrenaline is produced in the medulla of the adrenal gland. The overall effect of adrenaline is to prepare the body for the fight or flight response in times of stress, i.e., for vigorous sudden action.
Key actions of adrenaline include increasing the heart rate, increasing blood pressure, expanding the air passages of the lungs, enlarging the pupil in the eye, redistributing blood to the muscles and altering the body's metabolism, so as to maximise blood glucose levels (primarily for the brain).
Progesterone allows the blastocyst for implanting and develop and protects against the expulsion of the developing pregnancy. Progesterone declines towards the time of delivery, leaving oestrogen to increase the uterine contractility.

So, the correct answer is option C.C.W
