Follicle-stimulating hormone

Mandy Roberson Endocrine System The endocrine system has to do with the hormones of the body. Hormones are chemical messengers that travel throughout the bloodstream to other tissues. These hormones are secreted by endocrine glands throughout the body. Hormones help with the functions of certain organs and glands and help with digestion, muscle contraction, sex hormones for reproduction, sleep, and much more. They can really dictate how chemicals in the body react. The major function of the…

an array of hormones once it receives signals from the hypothalamus. These hormones are responsible for regulating the activities of the other glands, such as prolactin, which is involved in milk production, adrenocorticotropic hormone which responds to stress through a stimulation of the epinephrine, hormone responsible for the stimulation of thyroid, as well as the luteinizing hormone, which regulates ovulation timing and promotes sperm and egg development, follicle-stimulating hormone and sex…

If Ellie’s thyroid is hyperactive, it is releasing a large amount of thyroid hormone, meaning a large amount of T3 and T4. A large amount of T3 would greatly inhibit the release of TSH by the pituitary gland. This may appear paradoxical, as TSH stimulates the release of thyroid hormones, but in cases of hyperthyroidism, the excessive amounts of T3 and T4 are generally not caused by elevated levels of TSH. This is, unless, the aforementioned…

based on symptoms and the results of blood tests that measure the level of TSH and the level of the thyroid hormone thyroxine. The high level of TSH and low level of thyroid hormones as known as free T4 level indicate an underactive thyroid hormone or hypothyroidism. When the thyroxine level is low, the pituitary gland produces TSH to stimulate thyroid gland to produce more thyroid hormone. TSH tests play an important role in managing hypothyroidism. They help the provider to determine the right…

Hypothyroidism Hypothyroidism, also known as an underactive thyroid, refers to a lack of thyroid hormone produced by the thyroid gland. Thyroid hormone affects the activity of almost every organ and tissue in the body. The thyroid gland, located in the medial, inferior portion of the cervical region, lateral and ventral to the trachea, helps to regulate the body’s metabolism, heart rate, and energy levels (“Hypothyroidism (Underactive Thyroid)”, WebMD 1). Approximately 20 million Americans…

Introduction In vertebrates, reproduction is primarily controlled by the hypothalamus-pituitary-gonad axis. The gonadotropin-releasing hormone (GnRH) neurons in the hypothalamus are key regulators of the hypothalamic neuroendocrine system mainly though the synthesis of GnRH (Moenter et al., 2003). The decapeptide GnRH is released from the hypothalamus in a pulsatile manner, and the amplitude and frequency of these pulses change throughout the estrous cycle (McCartney et al., 2002; Moenter et al.…

If there are any abnormalities to the natural release of the hormones within the human body that could negatively influence the human body in a variety of aspects at different stages of their life. Through the time period of a child becoming an adult they could experience poor growth to their height as well as their internal organs (You & Your Hormones, 2014). The lack of grow into adulthood could negatively influence their sense of well being, and increase their risk of heart disease and the…

used voles as subjects, because of their distinct social behavior. They showed that prairie vole pups, which are part of monogamous species, react to social isolation with ultrasonic calls as well as an increase in corticosterone level, which is a hormone involved in stress responses. On the other hand, montane vole pups, which are promiscuous species, did not respond to social isolation as a stressor, but on the contrary did produce ultrasonic calls and presented a rise in corticosterone in…

According to WHO (World Health Organization) adolescence is the period that happens between the ages of 10 to 19 in which human growth and development occurs. Throughout the life span, adolescence signifies an important transition from childhood, as it is a period of ‘newness’ and change, which can be seen in the person, the dyad and the environment’. Linda P Spear supports this as she defines adolescence as ‘a period of physical, psychological and social transition between childhood and…
