Which of these is an example of positive feedback regulation in the endocrine system?
Which of these is an example of positive-feedback regulation in the endocrine system? The increase in LH that causes an increase in estrogen, which causes an increase in LH that occurs before ovulation, is an example of positive-feedback regulation, since the original stimulus, increased LH, is amplified or increased.
What is the main function of the endocrine system?
What Does the Endocrine System Do? Endocrine glands release hormones into the bloodstream. This lets the hormones travel to cells in other parts of the body. The endocrine hormones help control mood, growth and development, the way our organs work, metabolism , and reproduction.
What qualities should your feedback have?
In order to be effective, feedback must be:
- Specific. Feedback must be concrete and relate to a specific, measurable performance goal.
- Focus on behavior, not personality.
- Given using descriptive language.
- Not given using judgmental language.
- Based on accurate and credible information.
Which of these are examples of positive feedback?
Positive Feedback Loops
- Example 1: Fruit Ripening.
- Example 2: Childbirth.
- Example 3: Blood Clotting.
- Example 1: Temperature Regulation.
- Example 2: Blood Pressure Regulation (Baroreflex)
- Example 3: Osmoregulation.

Why feedback is important in communication?
Feedback is essential in communication so as to know whether the recipient has understood the message in the same terms as intended by the sender and whether he agrees to that message or not. Feedback also enables us to evaluate the effectiveness of our message. It makes communication meaningful.
Why delivery of a child is a positive feedback system?
The release of oxytocin from the posterior pituitary gland during labor is an example of positive feedback mechanism. Oxytocin stimulates the muscle contractions that push the baby through the birth canal. Positive feedback increases the deviation from an ideal normal value.
What do all hormones have in common?
The correct answer: The character that all hormones have in common is (c) They bind to and interact with a receptor in the target cell.
Which of the following are functions of the endocrine system?
Endocrine System Functions
- Makes hormones that control your moods, growth and development, metabolism, organs, and reproduction.
- Controls how your hormones are released.
- Sends those hormones into your bloodstream so they can travel to other body parts.
Which of the following is the best example of positive feedback?
The process of labor and childbirth is perhaps the most-cited example of positive feedback. In childbirth, when the fetus’s head presses up against the cervix, it stimulates nerves that tell the brain to stimulate the pituitary gland, which then produces oxytocin. Oxytocin causes the uterus to contract.
Why is feedback important in teaching?
studied and gives them clear guidance on how to improve their learning. ‘ Feedback can improve a student’s confidence, self-awareness and enthusiasm for learning. Effective feedback during the first year in university can aid the transition to higher education and may support student retention.
Which of the following is an example of positive feedback control?
The hypothalamus releases a hormone called. LH is responsible for Sperm and Testosterone production. GnRH then stimulates Pituitary to produce more LH which in turn elevates the Testosterone level. This mechanism is an example of Positive Feedback Control in the reproductive system in our body.
What is feedback in teaching/learning process?
Feedback is information given to the learner or teacher about the learner’s performance relative to learning goals or outcomes. It should aim towards (and be capable of producing) improvement in students’ learning.
Why is it important to give feedback to parents?
It is vital to provide feedback to parents that recognizes what students are doing well. We often express what students do wrong, but seldom reward and recognize good performance. Similar to most people, students respond when they are recognized.
What is positive feedback in anatomy?
Medical Definition of Feedback In positive feedback, the body changes from the normal point and amplifies it. Examples include blood clot formation, lactation, contractions during childbirth, and fever.
What is an example of positive feedback in the endocrine system?
An example of positive feedback is milk production by a mother for her baby. As the baby suckles, nerve messages from the nipple cause the pituitary gland to secrete prolactin. Prolactin, in turn, stimulates the mammary glands to produce milk, so the baby suckles more.
What is the effect of positive feedback on stability of the system?
Positive feedback is not used generally in the control system because it increases the error signal and drives the system to instability.
Does positive feedback occur in the body?
There are few examples of positive feedback loops that exist in animal bodies, but one is found in the cascade of chemical reactions that result in blood clotting, or coagulation. Another example of positive feedback is uterine contractions during childbirth.
What are the advantages of feedback?
