Bone quiz (fractures, inside the bone, types of bones)

Spongy Bone

A type of bone tissue that is characterized by a porous, honeycomb-like structure, providing strength and support while being lightweight. It is typically found at the ends of long bones, interior of bones, and makes up flat and irregular bones. (Made of tiny rods and plates called trabeculae)

Compact bone

A dense and strong type of bone tissue that forms the outer layer of bones, providing structure and protection. It contains fewer pores than spongy bone, making it thicker and more robust. It contains the central canal which holds blood vessels and nerves (Made of osteons)

Label the long bone

Three types of bone fractures

Bending (Straight line across the bone), twisting (diagonal lines), Impact (crushed)

What is the anatomy of the femur

Osteoclasts

Large multi-nuclei cells that break down and dissolves bone tissue during bone remodeling, repair, and maintenance of blood calcium levels.

osteoblasts

Cells responsible for creating new bone tissue to reshape bones during growth and heal fractures.

Hematoma formation

First stage of bone fracture repair where torn blood vessels bleed and form a mass of clotted blood at the fracture site

Stages of bone tissue formation

hematoma formation, fibrocartilage callus formation, bony callus formation, bone remodeling

Fibrocartilage callus formation

New capillaries form into the clotted blood, connective tissues form a mass of repair tissue called F. Callus which closes the gap between the broken bones

Bony callus formation

The F.Callus is gradually replaced by one made of spongy bone. Osteoclasts and osteoblasts multiply

Bone Remodeling

Over time, the callus is remodeled with osteoblasts and osteoclasts help. The shape returns to normal.

Tendons

Tough flexible cord of connective tissue that connects your muscles to your bones

Skeletal muscle

striated, voluntary, striped tissues attached to bones that your body uses to move

Smooth muscle

a type of involuntary, non-striped muscle tissue found in the walls of hollow internal organs that works automatically without conscious control

Cardiac muscle

the special, strong muscle that makes up the walls of your heart and pumps blood all over your body
