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.
