What are two ways unicellular organisms without movement structures are transported?

They are transported by water, air, or animals.

What structure do some bacteria have for movement?

A flagellum.

How does the amoeba move?

By extending their pseudopods.

Why is movement essential for many multicellular organisms?

To find mates, shelter, water, and food.

How many bones does the human skeleton consist of?

206 bones.

Are bones living or non-living tissues?

Living tissues.

What is produced in the bone marrow of some bones?

Red and white blood cells.

Which mineral is essential to ensure your bones are strong and healthy?

Calcium.

Name eight major bones in the human body.

Skull, jaw, collarbone, ribs, sternum, vertebral column, pelvis, humerus, ulna, radius, femur, kneecap, fibula, tibia. (Note: more than eight listed in original)

What are the four main functions of the skeleton?

Support, protection, making blood cells, and movement.

What is the point at which two bones meet called?

A joint.

What are the three types of joints mentioned?

Hinge joint, ball and socket joint, fixed joints.

Which type of joint allows movement backwards and forwards (e.g., elbow and knee)?

Hinge joint.

Which type of joint allows movement in all directions (e.g., shoulder or hip)?

Ball and socket joint.

Which type of joint allows no movement (e.g., the skull)?

Fixed joints.

What connects muscle to bone?

A tendon.

What is the tissue at the end of bones that prevents them rubbing together and wearing away?

Cartilage.

What connects bones together at a joint?

Ligaments.

What fills the joint for lubrication to prevent friction?

Fluid.

What type of cells make up muscle tissue, and what do they have lots of?

Muscle cells; they have lots of mitochondria to release energy through respiration.

Name six major groups of muscles mentioned.

Neck muscles, triceps, biceps, abdominal muscles, quadriceps, calf muscles.

What is an antagonistic pair of muscles?

A pair of muscles that work together where as one relaxes, the other contracts (e.g., biceps and triceps).

To bend the arm, what do the bicep and tricep do?

The bicep contracts and the tricep relaxes.

To straighten the arm, what do the biceps and triceps do?

The biceps relaxes and the triceps contracts.
