Summary
The vascularization of the axis bone in human fetuses and adults reveals distinct arterial patterns. Adult axis bone exhibits anastomoses between the dens and vertebral body, unlike fetuses.
Area of Science:
- Anatomy
- Vascular Biology
- Histology
Context:
- Microangiographic study of axis bone vascularization.
- Comparison between fetal and adult specimens (5 fetuses, 8 adults).
Purpose:
- To elucidate the arterial supply of the axis bone.
- To investigate the development of vascular connections within the axis.
Summary:
- Arterial supply to the axis originates from the vertebralis artery.
- Two distinct arterial arches are identified in the cervical vertebrae.
- Fetal axis bone shows no anastomoses between the dens and vertebral body, while adults do.
Impact:
- Provides detailed anatomical knowledge of axis bone vascularization.
- Highlights developmental changes in vascular patterns.
- Identifies the dens neck as a potentially less vascularized region.
