joints
joints that fuse together often found in the skull
immovable joints
three kinds of muscles
skelital muscle smooth muscle and cardiac muscle

What are growth plates, and what role do they play in bone growth?
Growth plates are areas of cartilage near the ends of long bones where new bone tissue is added, allowing bones to grow longer.
What is the main function of the skeletal system?
The skeletal system supports the body, protects organs, helps with movement, produces blood cells, and stores minerals.
This movement occurs around a single axis, enabling actions such as turning your head from side to side.
pivot joint
Tendons are strong bands of fibrous connective tissue that attach muscles to bones.

babies have more bones than an adult
true
What is the difference between voluntary and involuntary muscles?
Voluntary muscles are under conscious control while involuntary muscles work automatically
What is the difference between a tendon and a ligament?
Tendons connect muscle to bone, while ligaments connect bone to bone.
joints that allow a small amount of movement between the bones. They are connected by cartilage, which provides flexibility while still keeping the bones firmly joined.
slightly movable joint
difference between striated and non striated muscles
Striated muscles move the skeleton and are under voluntary control, while non-striatedmuscles control internal organs and work automatically.
red blood cells can be made in the bone
true
What mineral is stored in bones and helps keep them strong?
Calcium
What type of joint is found in the shoulder and hip, and what movements does it allow?
A ball-and-socket joint; it allows movement in many directions, including rotation.
This structure allows the widest range of movement of any joint type.
ball in socket joint
the action of one muscle contracting while the other is relaxed
antagonist pair

false
What is the name of the process by which red blood cells are produced?
Erythropoiesis
How do muscles contract to produce movement?
Muscles contract when actin and myosin filaments slide past each other, shortening the muscle fiber.
a type of joint that allows movement in one direction, similar to the way a door hinge opens and closes.
hinge joints

What is the difference between compact bone and spongy bone?
Compact bone is dense and hard while spongy bone is lighter and contains many spaces often filled with bone marrow.
What is an antagonistic pair of muscles? Give an example.
An antagonistic pair consists of two muscles that work opposite each other; for example, the biceps and triceps. When one contracts, the other relaxes.
