Bone Formation by Endochondral Ossification01:24

Bone Formation by Endochondral Ossification

3.8K
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 Formation by Intramembranous Ossification

5.4K
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 ...

Changes in the Appendicular Skeleton with Age

1.8K
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...

Development of the Heart01:27

Development of the Heart

861
The development of the human heart, a crucial organ, commences from the mesoderm on the 18th or 19th day after fertilization. This process initiates in the cardiogenic area, a group of mesodermal cells at the embryo's head end, which evolves into elongated strands known as cardiogenic cords. These cords undergo a transformation to form hollow-centered endocardial tubes.
As the embryo undergoes lateral folding, these paired tubes approach each other, merging into a single primitive heart...

Summary
This summary is machine-generated.

Persistent epigastric pain after a pericardial window procedure may indicate heterotopic ossification. Surgical removal of this bone growth can provide lasting relief, as seen in this case study.

Area of Science:

  • Medical Case Study
  • Surgical Pathology

Background:

  • A 58-year-old man experienced persistent epigastric pain years after a pericardial window procedure for viral pericarditis.
  • This discomfort was localized to the subcutaneous epigastric region.

Observation:

  • Computed tomography revealed a calcified subcutaneous mass in the epigastric area.
  • Surgical excision was performed to address the persistent pain and the detected mass.

Findings:

  • The excised mass was identified as a heterotopic ossification lesion.
  • The lesion originated from the inferior margin of the xiphoid process.

Implications:

  • Heterotopic ossification should be considered in the differential diagnosis of persistent pain post-pericardial window surgery.
  • Surgical intervention for heterotopic ossification can lead to significant and sustained pain improvement.
