Muscles Used In The Endocrine System

Muscles Used In The Endocrine System

The endocrine system is made of glands that produce and secrete hormones. These glands are ductless and do not make use of any muscle or muscle groups. For example, the pituitary and the hypothalamus are both situated in the brain. The anterior pituitary is made up of protein secreting cells while the posterior pituitary is not an organ but just a collection of hypothalamic neurons.

However, the endocrine glands affect muscles in the body. The testosterone, which is secreted by the male sex organs, increase muscles in males upon puberty. Sometimes, wrestlers and bodybuilders will have higher testosterone levels than other individuals. Right from birth, the growth hormone, GH stimulates the body to build muscle tissues. Though the amount of secretion will vary during the lifetime of a person but it will continue secreting the growth hormone. 
  

Another influence hormones have on the human female body is during pregnancy and labor. The hormone oxytocin is the one that starts muscle contractions which facilitate the baby to come out of the birth canal during labor and delivery. Once the baby is pushed out of the birth canal, the production of oxytocin is stopped.

Also, more muscles in the body means less fat, and less chance of being overweight. This will help the endocrine system, especially in the production of insulin. It will help insulin control the cells and tissues to make use of the energy received by food. In turn, this will prevent the person from getting Type II Diabetes mellitus.

An inter-relation between the muscles and the endocrine glands and hormones is quite evident from the above examples.
