Skeletal System 1

What are the main components of the axial skeleton?

• Skull, pelvis, sternum

• Pelvis, femur, humerus

• Skull, vertebral column, rib cage

• Vertebral column, scapula, tibia

Name three bones that are part of the appendicular skeleton.

• rib

• skull

• humerus, femur, scapula

• vertebrae

What is the primary function of the vertebral column?

• The primary function of the vertebral column is to support the body and protect the spinal cord.

• To facilitate breathing and digestion.

• To store calcium and phosphorus.

• To produce red blood cells.

Identify a characteristic feature of long bones.

• Long bones have a diaphysis that is longer than it is wide.

• Long bones have a wider diaphysis than their length.

• Long bones are always curved in shape.

• Long bones are primarily found in the skull.

What is the role of the diaphysis in a long bone?

• The diaphysis is responsible for bone growth in length.

• The diaphysis provides structural support and houses the medullary cavity in a long bone.

• The diaphysis connects the epiphyses in a long bone.

• The diaphysis produces red blood cells in a long bone.

List two examples of short bones in the human body.

• Radius and ulna

• Scapula and clavicle

• Femur and tibia

• Carpals and tarsals

What type of joint allows for the greatest range of motion?

• Ball-and-socket joint

• Saddle joint

• Pivot joint

• Hinge joint

Describe the structure of a typical long bone.

• A typical long bone consists only of the diaphysis and epiphyses.

• A long bone has a single structure called the cortex without any other components.

• A typical long bone has a diaphysis, epiphyses, metaphysis, medullary cavity, and periosteum.

• Long bones are primarily made up of cartilage and do not have a medullary cavity.

What is the function of the epiphysis in long bones?

• The epiphysis primarily stores fat for energy.

• The epiphysis is involved in the production of hormones.

• The epiphysis is responsible for nutrient absorption.

• The epiphysis functions in joint formation, muscle attachment, and blood cell production.

How do short bones differ from long bones in structure?

• Short bones are longer and provide flexibility.

• Short bones have a shaft and are designed for movement.

• Long bones are cube-shaped and provide stability.

• Short bones are cube-shaped and provide stability, while long bones are longer, with a shaft and ends, designed for movement.
