1.1 & 1.2 Skeletal and Muscular System

What are the four main functions of the skeleton?

• Storage of fat, hormone production, immunity, and energy release.

• Digestion, respiration, excretion, and sensation.

• Temperature regulation, nutrient absorption, waste elimination, and muscle contraction.

• Support, protection, movement, and blood cell production.

Name the bone that protects the brain.

• Skull

• Clavicle

• Femur

• Rib

Which bone is known as the collarbone?

• clavicle

• scapula

• humerus

• sternum

Identify the bone that forms the upper arm.

• scapula

• humerus

• ulna

• radius

What is the function of the radius?

• The radius measures the angle of a circle.

• The radius is the distance from the center to the edge of a square.

• The radius indicates the color of a circle.

• The radius defines the size of a circle.

Which bones make up the wrist?

• Metacarpals, phalanges, carpals, tarsals

• The wrist is made up of the scaphoid, lunate, triquetrum, pisiform, trapezium, trapezoid, capitate, and hamate bones.

• Radius, ulna, femur, tibia

• Humerus, scapula, clavicle, vertebrae

Classify the femur as a long, short, or flat bone.

• flat bone

• irregular bone

• long bone

• short bone

What type of joint is the knee?

• Hinge joint

• Saddle joint

• Pivot joint

• Ball-and-socket joint

Describe the structure of a synovial joint.

• A synovial joint is made up of muscle tissue and blood vessels.

• A synovial joint consists of a joint capsule, synovial fluid, articular cartilage, ligaments, and a synovial membrane.

• A synovial joint consists of only bones and tendons.

• A synovial joint includes a nerve network and skin layers.

What is the role of synovial fluid?

• To store excess fat in the joints

• To produce red blood cells

• To connect bones together

• The role of synovial fluid is to lubricate joints, provide nutrients to cartilage, and act as a shock absorber.
