The skeletal system, along with muscles, helps the body do this essential action.
What is movement?
100
This muscle is responsible for pumping blood throughout the body.
What is the heart?
100
This type of joint allows for no movement.
What is a fibrous joint?
100
This common bone condition is characterized by low bone density.
What is osteoporosis?
100
This bone group is composed of the mandible, maxilla, and occipital bones, among others.
What is the skull?
200
The skeletal system stores this essential mineral needed for strong bones and muscle function.
What is calcium?
200
Muscles contract when this energy molecule is broken down, providing the necessary power for movement.
What is ATP (adenosine triphosphate)?
200
This joint connects the femur and the tibia.
What is the knee joint?
200
This common joint condition causes pain, stiffness, and inflammation, sometimes leading to bone spurs.
What is arthritis?
200
The pubis, coccyx, ischium, ilium, and sacrum make up this bone structure.
What is the pelvis?
300
This structure, composed of the sternum, ribs, and vertebrae, protects vital organs like the heart and lungs while aiding in respiration.
What is the thoracic cage?
300
The three types of muscle in the human body are skeletal, cardiac, and this.
What is smooth muscle?
300
This type of joint allows movement in only one direction.
What is a hinge joint?
300
This common bone condition is characterized by low bone density.
What is osteoporosis?
300
This bone, shown in this image, is the longest, strongest bone in a human body.
What is a femur bone?
400
The human body has this many bones at birth, but some fuse together as we grow.
What is 300?
400
This protein blocks myosin-binding sites on actin filaments, preventing muscle contraction until calcium is present.
What is tropomyosin?
400
The shoulder and hip joints allow a wide range of motion because they are this type of joint.
What is a ball-and-socket joint?
400
This type of absorptiometry is used in diagnoses for osteoporosis
What is dual-energy X-ray absorptiometry?
400
Bone is also known as the shoulder blade.
What is the scapula?
500
Number of bones in an adult human skull.
What is 22?
500
This muscle relaxes or opposes the movement of the agonist.
What is an antagonist?
500
This substance exists within joints, helping to reduce friction and keep them moving smoothly.
What is synovial fluid?
500
Osteoporosis occurs when these bone-resorbing cells outpace bone-building cells, leading to weakened bones.
What are osteoclasts?
500
Bones shown in pink.
What are the metacarpals?
