Flashcards

Long bones

Bones that are longer than they are wide, featuring a shaft and two ends.

Short bones

Bones that are cube-shaped and primarily composed of spongy bone.

Flat bones

Bones that are thin, flattened, and curved, commonly found for protection.

Irregular bones

Bones with complex shapes that don't fit into other categories, primarily composed of spongy bone.

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.
