Hormones and Bone Tissue

Hormones and Bone Tissue

The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

Major Hormones and Their Functions

Major Hormones and Their Functions

Hormones, the biochemical messengers produced by endocrine glands, are pivotal in regulating bodily functions and maintaining homeostasis. Each hormone's balance is crucial; imbalances can lead to significant physiological disruptions. Major hormones include oxytocin, cortisol, epinephrine, estrogen, testosterone, thyroxine, growth hormone, insulin, and glucagon.
Oxytocin, produced in the hypothalamus and released by the pituitary gland, plays a role in social bonding, childbirth, and lactation.

Nature and Nurture

Nature and Nurture

Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience, such as differences...

Hormones Regulating Blood Glucose

Hormones Regulating Blood Glucose

Insulin is released by beta cells of the pancreas when blood glucose levels are high. It facilitates glucose absorption and utilization in insulin-dependent cells with insulin receptors on their plasma membranes. Insulin promotes glucose uptake by increasing the number of glucose transport proteins in the cell membrane, allowing glucose to enter the cell. As a result, glucose utilization and ATP production are enhanced.
In addition to accelerating glucose uptake and utilization, insulin has...

Hormones of the Pituitary Gland

Hormones of the Pituitary Gland

The small, pea-sized pituitary gland is located at the base of the brain. It is crucial in regulating various bodily functions, from growth to reproduction. The gland is divided into the anterior lobe and the posterior lobe. The secretory cell clusters in the pars distalis of the anterior pituitary lobe are controlled by hypothalamic regulators and synthesize six primary hormones.
The most abundantly secreted hormone from the anterior lobe is the growth hormone, which controls overall growth by...

Signs of Puberty

Signs of Puberty

Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...

Summary

Parents frequently use the internet for growth hormone (GH) information for their children. However, online content may be incomplete or biased, necessitating critical evaluation skills.

Area of Science:

Pediatric Endocrinology
Health Communication
Digital Health Literacy

Background:

Parental knowledge significantly impacts pediatric medical care decisions.
The internet is a primary source of health information for parents.

Purpose of the Study:

To evaluate the quality and content of online information regarding growth hormone (GH) for children.
To understand how parents access and perceive GH information online.

Main Methods:

Conducted open focus groups with parents of pediatric patients (aged 9-14).
Analyzed the top Google search results for 'growth hormone children' and 'parents of children who take growth hormone'.
Performed independent content analysis of 18 websites by three investigators.

Main Results:

Most reviewed websites were educational (56%) and commercially funded (44%).
GH treatment information varied; only 33% covered all US FDA-approved indications.
Psychosocial benefits were discussed on 56% of sites, often controversially (44%).
Risks and costs were omitted from 39% of websites despite parental importance.

Conclusions:

Internet-based GH information for children can be incomplete and biased.
Healthcare providers should equip parents with tools to critically assess online health information.
Consider providing curated resources or educational materials to parents seeking GH information.
