skeletal system

Cartilage

Flexible connective tissue found at joints, reducing friction and cushioning bones.

Ligaments

Tough, fibrous connective tissues that connect bones to other bones at joints.

Bone marrow

Soft tissue inside bone cavities where blood cell production (hematopoiesis) occurs.

Long bones

Bones characterized by an elongated shaft and two enlarged ends, functioning primarily as levers for movement.

Short bones

Roughly cube-shaped bones that offer stability and support while allowing limited motion.

Flat bones

Thin, broad plates of bone designed to protect internal organs and provide broad surfaces for muscle attachment.

Irregular bones

Bones with complex, unique shapes that do not fit standard categories, providing specialized protection or support.

Sesamoid bones

Small, rounded bones embedded within tendons to reduce friction and protect the tendon from stress.

Finger bones

Also known as phalanges; small long bones of the hand that enable dexterity and grasping.

Red blood cells

Cells produced in red bone marrow that contain hemoglobin and transport oxygen throughout the body.

White blood cells

Immune system cells produced in bone marrow that defend the body against pathogens and infection.

Platelets

Cell fragments formed in bone marrow that play a crucial role in blood clotting and wound healing.

Hemoglobin

An iron-containing protein inside red blood cells that binds oxygen for transport to tissues.
