locomotor system {bone}

Osteology

The study of bones and the skeletal system.

Locomotor System

The system in the body that facilitates movement, primarily through bones, muscles, and joints.

Bones

The primary structural elements providing support and shape to the body.

Muscles

Tissues that attach to bones and contract to produce movement.

Joints

Connections between bones that allow for flexibility and movement.

Functions of the Locomotor System

Provides structure, protects vital organs, and facilitates movement through coordinated action of bones and muscles.

Long Bones

Bones such as the femur and humerus, responsible for movement and support.

Short Bones

Bones such as carpals and tarsals, providing stability and support with little movement.

Flat Bones

Bones such as the skull and ribs, providing protection to internal organs.

Irregular Bones

Bones such as vertebrae, serving specific functions in the body.

Axial Skeleton

Consists of bones of the skull, vertebral column, and rib cage.

Appendicular Skeleton

Consists of bones of the limbs and girdles (shoulder and pelvis).

Articular Cartilage

Smooth tissue covering the ends of bones to reduce friction in joints.

Compact Bone

Dense outer layer of bone providing strength, made up of tightly packed columns known as osteons.

Spongy Bone

A lighter, porous structure found inside bones, housing bone marrow.

Bone Cells

Osteoblasts build new bone, osteoclasts break down bone, and osteocytes maintain bone tissue.

Diploe

The spongy bone layer found between the inner and outer layers of the flat bones of the skull.
