Transcript of Oxytocin

By: Abby and Elisa
Oxytocin
Oxytocin is a hormone that is released by the pituitary gland and causes increased contraction of the uterus during labor and stimulates the ejection of milk into the ducts of the breasts.
Pituitary adenoma- Non cancerous tumors that occur in the pituitary gland.
Hyperprolactinema- Excess prolactin (hormone that produces breast milk)
Prolactinoma- Noncancerous pituitary tumor that produces the hormone prolactin.
Hypothyroidism- Condition when thyroid gland doesn't make enough thyroid hormone.
Pituitary Tumor- Near the brain, doesn't spread to other areas, secrete excess hormones.

Oxytocin is secreted within the brain and from other tissues.
When the cells are excited it releases into the blood.
It depends on electrical activity of neurons in the hypothalamus.


Production of Oxytocin
Oxytocin is produced in the hypothalamus.
Then secreted into the bloodstream by the posterior pituitary gland.
It acts on the breasts and uterus as a chemical messenger in the brain controlling the reproductive system including childbirth and lactation.

Causes and Symptoms of hypersecretion
Secretion
Prepares the body for childbirth.
Facilitating the bond between mother and child.
In the last month of pregnancy more oxytocin developes.
When oxytocin is released the uterus contracts.
Helps push out the baby.
Oxytocin as feed initiator: maintaining homeostasis in consummatory behavior.
Galactorrhea- Leaking milk from breast
It will often lower the moms blood pressure and cause the baby stress.
Clinical Use
Oxytocin is injected though IV, in the hospital.
Your vitals and contractions will be watched closely.
The baby's heart beat will be watched with a fetal heart monitor to evaluate any effects of oxytocin on the baby.
Symptoms of Oxytocin
Nausea and vomiting
Runny nose, sinus pain or irritating
Memory problems
More intense/ frequent contractions
Depression
Anxiety

The Normal Function
Causes and Symptoms of Hyposecretion
When there is hypersecretion it can be very harmful to the mom and the baby.
