Changes in the Appendicular Skeleton with Age01:09

Changes in the Appendicular Skeleton with Age

4.0K
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...

Introduction to the Skeletal System

10.8K
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 Formation by Intramembranous Ossification01:29

Bone Formation by Intramembranous Ossification

15.8K
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 ...

Bone Formation by Endochondral Ossification01:24

Bone Formation by Endochondral Ossification

14.1K
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...

Development of the Limb Synovial Joints

2.7K
Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
During development, the limbs...

Skeletal Muscle Anatomy00:55

Skeletal Muscle Anatomy

95.7K
Skeletal muscle is the most abundant type of muscle in the body. Tendons are the connective tissue that attaches skeletal muscle to bones. Skeletal muscles pull on tendons, which in turn pull on bones to carry out voluntary movements.

Area of Science:

  • Pediatric Endocrinology
  • Musculoskeletal Health
  • Bone Biology

Background:

  • The interplay between muscle and bone is critical for skeletal development in children.
  • Factors like muscle adiposity, endocrine status, and lifestyle significantly impact this relationship.

Purpose of the Study:

  • To review recent clinical findings on muscle-bone interactions in pediatric populations.
  • To explore the roles of muscle adiposity, endocrine factors, and lifestyle in pediatric musculoskeletal development.

Main Methods:

  • This is a review article summarizing existing clinical findings.
  • Focus on prospective studies and their contributions to understanding muscle-bone relationships.

Main Results:

  • Positive associations exist between muscle characteristics (mass, size, function) and cortical bone geometry.
  • Muscle fat is linked to impaired glucose metabolism and reduced muscle function, potentially affecting bone growth.
  • Healthy diets and physical activity enhance the muscular phenotype and endocrine profile, supporting skeletal development.

Conclusions:

  • Muscle and bone are closely linked, but this relationship is modulated by factors like sex, maturation, and study design.
  • Further research is needed to understand muscle adiposity's impact on cardiometabolic health, muscle function, and pediatric bone health.
  • Adhering to age-specific diet and physical activity guidelines is essential for optimal muscle and bone development.
