There are two hormones, T3 and T4
its what happens when a drug decreases the effect of another drug
cells & organs
A muscle sprain can tear a ligament which holds two bones together.
Two primary agents of cellular communication are hormones, which are secreted by endocrine glands and travel through the bloodstream to target cells, and neurotransmitters, which are released by neurons in the nervous system to communicate with other neurons or muscle cells.
From what i know they are used in the cccell membrane and for hormones
inhibin & ABP ( androgen -binding pro.)
Two primary agents of cellular communication are hormones, which are chemical messengers released into the bloodstream to travel to target cells, and neurotransmitters, which are chemical messengers released by neurons to signal neighboring cells.
The two primary substances associated with healthy bones are both Calcium and Vitamin D.
The Two female hormones are Estrogen and Progesterone
Luteinizing Hormone
The process by which two hormones exert opposite effects is known as antagonism. Antagonism occurs when one hormone inhibits the actions of another hormone by competing for the same receptors or signaling pathways within the body. This leads to a counterbalancing effect that helps maintain homeostasis.
