Study Notes
Bone Types and Characteristics
- Irregular bones primarily consist of spongy bone.
- Flat bones provide a framework that supports and anchors all soft organs.
- The primary function of flat bones is to provide protection and support for internal organs.
Bone Structure
- Irregular bones have complicated shapes and mainly consist of spongy bone enclosed by thin layers of compact bone.
- Long bones are distinguished from other types of bones by their elongated shape, with a shaft (diaphysis) and two ends (epiphyses).
Bone Components
- Flat bones, such as the cranial bones, contain a layer of spongy bone (diploe) between two compact bone surfaces.
- Hematopoiesis, the process of blood cell formation, occurs in the bone marrow.
Bone Growth and Development
- The process of bone growth that involves osteoblasts secreting bone matrix on the external surface is called appositional growth.
Bone Anatomy
- A spine, in relation to bone anatomy, refers to the vertebral column, which is composed of individual vertebrae.
- The condyle is a rounded protuberance located at the end of a bone, typically involved in joint formation.
- A tubercle is a small bony prominence that serves as an attachment site for muscles and tendons.
