Study Notes
Osseous Tissues
- Two primary types: compact bone and spongy (cancellous) bone.
Compact Bone
- Dense structure consisting of osteons, which are the organizational units.
Spongy Bone
- Made of small trabeculae (columns) and contains a significant amount of open space.
Bone Classifications
- Four major groups: long bones, short bones, flat bones, and irregular bones.
Long Bones
- Characterized by being longer than wide, featuring a shaft and end heads, primarily composed of compact bone.
- Examples include the femur and phalanges.
Short Bones
- Generally cube-shaped, contain more spongy bone than compact bone.
- Examples include tarsals and carpals.
Flat Bones
- Thin structure, with two layers of compact bone encasing a thicker layer of spongy bone.
- Often curved, as seen in cranial bones.
Irregular Bones
- Do not fit into other classifications, such as vertebrae.
Sesamoid Bones
- Specialized short bones located within tendons.
- Example includes patellas (kneecaps).
Sutural Bones
- Small bones found between cranial bones.
