Changes in the Appendicular Skeleton with Age01:09

Changes in the Appendicular Skeleton with Age

2.1K
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Signs of Puberty

423
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)...

Introduction to the Skeletal System01:20

Introduction to the Skeletal System

5.8K
The skeletal system is the central framework of the body, consisting of different connective tissues: bones, cartilage, tendons, and ligaments.
Components of the Skeletal System
Bone, or osseous tissue, is a hard connective tissue that forms an internal support structure for the human body. Bones shield vulnerable organs and soft tissue from external forces. For example, the vertebral bones protect and support the spinal cord.
Cartilage, a semi-rigid connective tissue found in regions such as...

Bone Disorders01:29

Bone Disorders

3.7K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Bone Formation by Intramembranous Ossification01:29

Bone Formation by Intramembranous Ossification

6.4K
Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into ...

Body Water Content and Fluid Compartments

811
Life's biochemical processes occur within aqueous solutions. Solutes are substances that are dissolved within these solutions. The human body contains a variety of solutes, which can differ across various body parts. These can encompass proteins—such as those responsible for clotting and carbohydrate transport—as well as electrolytes. In medicine, an electrolyte is often described as a mineral ion derived from a salt possessing an electric charge. Examples include sodium ions...

Area of Science:

  • Pediatrics
  • Human Growth and Development
  • Nutritional Science

Background:

  • Infant anthropometry, like birthweight, is a traditional measure of physical growth.
  • Current WHO growth standards focus on size and shape, not body composition.
  • Understanding body composition quality is vital for optimal infant development.

Purpose of the Study:

  • To highlight the historical challenges in assessing infant body composition.
  • To introduce advanced methods for measuring body composition in infants.
  • To advocate for the development of global reference charts for infant body composition.

Main Methods:

  • Utilizing air displacement plethysmography (ADP) for body composition assessment.
  • Employing stable isotope techniques, specifically deuterium dilution (DD), to measure total body water (TBW).
  • Applying a two-compartment model to quantify lean and fat tissue.

Main Results:

  • Recent advancements have improved the ability to assess infant body composition.
  • Stable isotope and ADP methods enhance the understanding of growth quality.
  • A significant gap exists in global reference data for infant body composition.

Conclusions:

  • Accurate body composition assessment is essential for evaluating infant health.
  • Advanced techniques like ADP and DD are key to understanding growth quality.
  • The development of global infant body composition reference charts is a critical next step.
