Insulin and glucagon are antagonistic hormones. They have opposing effects. Insulin lowers blood glucose and glucagon increases blood glucose levels.

Adrenaline is the hormone that helps to cope up with any emergency situation or stress. In the situation given, adrenaline will be released to cope up with the emergency.

Testosterone is released from testes and oestrogen from ovary. These two hormones are responsible for changes during puberty.

Auxins cause cells to become longer. On exposure to sunlight, by releasing auxins on one side of a stem but not on the other side, a stem will bend because one side becomes longer than the other. In geotropic movement also, the changed relations in the concentration of auxin leads to differential growth of the root tissues. Taken together, the root turns to follow the gravity stimuli. The redistribution of auxin causes the shoot to turn in a direction opposite to that of the gravity stimuli.

The two main actions of oxytocin in the body are contraction of the womb (uterus) during childbirth and lactation. Oxytocin stimulates the uterine muscles to contract and also increases production of prostaglandins, which increase the contractions further.

The cerebellum coordinates voluntary movements such as posture, balance, coordination, and speech, resulting in smooth and balanced muscular activity.
