What is 206?

100

These are the two primary "organs" that make up the entire skeletal system.


What are bones and joints?

100

This soft connective tissue found inside the pores of spongy bone is responsible for producing blood cells.

What is bone marrow?

100

This part of the skeleton consists of 80 bones along the body's center axis, including the skull and vertebrae.

What is the Axial Skeleton?

100

This dense, tough outer layer of bone provides strength and protection.

What is Compact Bone?

200

This specific type of connective tissue attaches bone to bone at the joints.

What are Ligaments?

200

The skeletal system works in conjunction with this other system to allow the body to move.

What is the Muscular System?

200

This medical condition is characterized by an abnormal side-to-side curvature of the spine, often noticed during adolescence.

What is Scoliosis?

200

This term refers to the process where bones release calcium into the blood to maintain a stable internal environment.

What is Homeostasis?

200

While most bones are long or flat, the kneecap (patella) belongs to this specific category of bones.

  1. What are Sesamoid Bones?

300

Often appearing in teenagers, this condition is characterized by a side-to-side curve in the spine.

What is scoliosis?

300

This condition, common in the elderly, involves the loss of bone tissue, making bones brittle.

What is osteoporosis?

300

This skeleton contains 80 bones along the center of the body, including the skull and rib cage.

What is the axial skeleton?
300

This dense, heavy outer layer makes up the exterior of the bone.

What is compact bone?

300

This tough, fibrous membrane covers and protects the very outer surface of the bone.

What is the periosteum?

400

This inflammatory disease doesn't just hurt the bones; it specifically damages the joints and surrounding tissue.

What is arthritis?

400

This part of the skeleton contains 126 bones and is primarily responsible for aiding with movement.

What is the appendicular skeleton?

400

These two "girdles" are the parts of the appendicular skeleton that connect your limbs to the center of your body.

What are the pelvic and shoulder girdles?

400

This process occurs inside the red bone marrow of larger bones, creating the cells that carry oxygen through your body.

What is blood cell production?

400

These specific connective tissues attach bone to bone.

What are ligaments?

500

It takes between 25 and this many pounds of pressure to cause a break or fracture in an average bone.

What is 160 pounds?

500

This disease causes the softening of bones and is usually caused by a lack of Vitamin D.

What is osteomalacia?

500

The skeletal system acts as an "anchor" for these, which pull on bones to allow the body to move.

What are the skeletal muscules?

500

This type of bone is found on the inside; it is lighter and porous, looking much like a kitchen tool used for cleaning.

What is spongy bone?

500

These connective tissues attach muscle to bone, allowing the skeleton to move when muscles contract.


What are tendons?
