Changes in the Appendicular Skeleton with Age01:09

Changes in the Appendicular Skeleton with Age

3.8K
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...

Population Growth

29.2K
Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.

Growth of Cartilage and Bone Tissue

4.5K
Chondrocytes form a temporary cartilaginous model by dividing and secreting a thick gel-like extracellular matrix. Once the chondrocytes undergo programmed cell death, osteoblasts enter the site of the cartilaginous model. The process of replacing the temporary cartilaginous model with bone in an ordered manner is called endochondral ossification. In endochondral ossification, not all of the cartilage is replaced by bone tissue. Some cartilage that performs a protective and supportive function...

Bones of the Lower Limb: Tibia and Fibula

13.8K
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...

Bone Formation by Endochondral Ossification01:24

Bone Formation by Endochondral Ossification

10.3K
Bone formation, or ossification, begins around the sixth to seventh week of embryonic development. Most bones develop from a cartilaginous template through the process of endochondral ossification. Cartilage formation begins when clusters of mesenchymal cells differentiate into chondrocytes. These chondrocytes proliferate rapidly and secrete an extracellular matrix that becomes encased in a membrane called the perichondrium. The resulting cartilage model provides a template that resembles the...

Bone Disorders01:29

Bone Disorders

5.7K
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...

Summary

Archaeological bone growth analysis reveals diminished early childhood growth velocity in the Libben skeletal collection, likely due to infectious disease, compared to modern children.

Area of Science:

  • Paleopathology
  • Bioarchaeology
  • Human Growth and Development

Background:

  • Traditional growth-attained curves show limitations in assessing long bone growth in past populations.
  • Understanding childhood growth patterns in archaeological samples is crucial for reconstructing past health and living conditions.

Purpose of the Study:

  • To develop and apply a novel method for determining age-specific growth velocity in an archaeological skeletal sample.
  • To compare childhood growth patterns between the Libben skeletal collection and a modern reference population.

Main Methods:

  • Normalized long bone diaphyseal lengths from the Libben skeletal collection (ages 0-12 years) were analyzed.
  • Derivatives of fitted growth curves were used to calculate age-specific growth velocity.
  • The Libben sample's growth velocity was compared to healthy Euroamerican children (Maresh data).

Main Results:

  • Growth patterns were largely similar between the Libben and Maresh populations.
  • A significant decrease in growth velocity was observed in the Libben sample during the first three years of life.
  • This period of depressed growth in the Libben sample correlates with evidence of high infectious disease levels.

Conclusions:

  • The study presents a more effective method for assessing growth velocity in archaeological human remains.
  • Early childhood infectious disease significantly impacted growth in the Libben population.
  • Bioarchaeological data can reveal critical insights into the health challenges faced by past populations.
