Study Notes
Locomotion
- Walking and running are two types of locomotion.
Animal Skeleton
- Bones are a key component of the animal skeleton.
Bone Functions
- Bones provide support for the body.
- Bones protect vital organs.
- Bones enable movement.
- Bones produce blood cells.
- Bones store minerals like calcium and phosphorus.
Types of Bones
- Sesamoid bone: Small, round bones found embedded in tendons near joints.
- The patella (kneecap) is an example of a sesamoid bone.
- Visceral or Splanchnic bone: Specialized bones that develop within soft organs.
- Examples include the os penis (found in dogs and cats) and the ossa cordis (found in the heart of ruminants).
Gross Anatomy of Long Bones
- Long bones are comprised of three main parts:
- Diaphysis: The middle shaft of the bone containing the medullary cavity.
- Epiphysis: The ends of the bone which are composed of spongy bone.
- Periosteum: A fibrous membrane that covers the outer surface of the bone.
- It is attached to the bone by Sharpey's fibers.
- Spongy Bone:
- Also known as cancellous bone.
- Composed of a network of bony trabeculae.
- Less dense than compact bone.
- Commonly found at the extremities of long bones.
