Why pheromone is called ectohormone?
Pheromones are called external hormones (ectohormones) because they act like hormones but on an animal different from the one that produces them. but this term is obsolete now because pheromones are no longer considered as hormones.
What is the difference between primary and secondary hypothyroidism.?
Primary hypothyroidism is caused by a deficiency in the thyroid itself. Secondary hypothyroidism is caused by an "outside" influence, usually a medication that causes the thyroid to not secrete the necessary hormones or an insufficient quantity, or may be caused by a primary disease process that in turn affects the thyroid gland. Sometimes secondary hypothyroidism is caused by the treatments for cancer, for example.
Is there a part of the brain that can detect what is in the blood and is not part of the BBB?
Yes, there are several. A major one would be the area postrema, which is located in the medulla. This area can "sample" the contents of the bloodstream. If it detects a toxin, vomiting is induced. Some hormones travel in the blood stream to get to their destination. The hypothalamus exploits the stream by sending certain neurohormones toward the pituitary gland. In this manner, the hypothalamus can exert some control over the pituitary gland.
What is exocythosis?
Exocytosis is a cellular process in which vesicles inside the cell fuse with the cell membrane and release their contents outside of the cell. This process is important for secretion of various molecules such as hormones, enzymes, and neurotransmitters.
What is lined with mucus secreting cells called mucosa?
esophagus Every system that has an outside opening produces mucous. This includes the respiratory, urinary, digestive and urogenital systems. Also the lining of the eye produces mucous. This substance keeps the membranes moist and prevents them from drying out.
How do feedback mechanisms control hormone production?
The hypothalamus releases hormones called releasing hormones. Some of the hormones they release also inhibit hormone release. So, the hypothalamus can either release:Releasing hormones, ORRelease inhibiting hormonesThese hormoens act on the aerior pituitary which ccuses the release oftrophic hrmones which are specific for target organs ie. Sex glands, thyroid glands, adrenal glands.The target glands release the hormone itself, which are called the non-trophic hormones. These hormones are responsible for causing a physiological effect. The hypothalamus is under the control of external stimulus ie. stress, the CNS, diet, and the immune system.Lots of things can control the release of releasing and release inhibitory hormones from the hypothalamus. At each level you have feedback inhibition. You get positive and negative input on the hypothalamus from outside the endocrine system and you get mostly negative influence on the hypothalamus from the anterior pituitary and the target organs.The trophic hormones can feedback and inhibit the hypothalamus. Even the physiological response to the hormone can feedback and affect target organs. This whole feedback loop is negative, but it can also be ostive. So, if hormone levels drop, or if stress increases, or diet changes, there will be a change in physiological response that will make feedback positive or negative to affect the hypothalamus.
How animals give birth?
Placental mammals go into labor when the developing fetus produces hormones which signal the mother's body that birthing is imminent. Uterine contractions cause the expulsion of the fetus through the birthing canal to the outside.

What is the chemical messenger of the nervous system?
There are three kinds of chemical messengers in the nervous system: Neurotransmitters, endorphins and hormones. 1) Neurotransmitters are released by transmitting neurons. They alter the activity of the receiving neurons. Note that neurotransmitters exist outside of the nervous system as well. Some neurotransmitters are: Serotonin, dopamine, acetylcholine, gamma-aminobutyric acid (GABA), norepinephrine (also a hormone) and glutamate. 2) Endorphins help in pain reduction, pleasure and even memory. 2) Hormones are affects the functioning of organs and are released by glands. Some hormones include: Melatonin, oxytocin, adrenal hormones (cortisol, epinephrine, norepinephrine) and sex hormones (androgens, estrogens and progesterone).
What produces protein for transport and use outside the cell?
Modifies protein. The Golgi body.
What is the legal age for females in Texas?
Teen abstinence is the safest, healthiest lifestyle, but understanding the power of the oxytocin hormone makes the importance of teen abstinence even clearer. Oxytocin is a hormone that is released in a woman during childbirth, nursing a child, and during sexual activity. It creates a strong bond between the woman and the other involved. In the case of childbirth and nursing this bond is important because it creates a nurturing environment for the child. In a marriage relationship where sex is safe and beneficial, oxytocin helps keep the bond between a husband and wife strong. Outside of marriage however, the oxytocin bond can increase the emotional pain when the relationship has ended. The oxytocin hormone is impartial. Whether during sexual activity between husband and wife or in a teenage hook-up, the hormone is still released and the bond is still created. Oxytocin promises an involuntary chemical commitment. The oxytocin bond explains why teens suffer emotionally after breakups, and often even during a relationship. Sex was created to unite two people, bringing a bond unlike any other relationship. This powerful bond is what sustains husband and wife until "death do us part" contributing to trust and security. Outside of marriage the release of oxytocin can lead to distrust, hostility, and insecurity. Sexual relationships without commitment still have a lasting bond. Oxytocin even has the power to sustain attachment within abusive relationships. Abstinence is the safest, healthiest choice for teens to prevent negative emotional, social and physical consequences. Even if the mind has set boundaries, the physiology of the body cannot. Abstinence protects from the emotional attachments that dramatically affect teens. But even more, abstinence protects their future.
