Main Organs of Skeletal System: bones, ligaments, tendons, and cartilage
Bone:
Provides the framework of the body (muscles and other tissues)
Promotes mobility by acting as levers and point of attachment for muscles
Serves as protection for other organs of the body
Types of bones:long, short, flat, irregular, and sesamoid bones
Examples of bones:skull, lower spine, and arm bone

Ligaments:
Every joint in the body
Connects two bones
Determines how much joints can move → stabilizes each joint and maintains the shape
Protects joints and bones: because of its ability to stretch and contract, it allows them to absorb shock under stress
Used as a part of the proprioception(ability to position any joint in the body) function in the body, which maintains the correct posture and movement of an individual

Tendons:
Fibrous connective tissues that attaches muscle to bones
Attaches muscles to structures like an eyeball
Serves to move the bone or structure
Acts as a bridge between muscles and bones
Regulates forces between muscle tissues during movement so body remains stable

Cartilage:
Flexible connective tissue that includes the joints between bones, the rib cage, the ear, the nose, the bronchial tubes, and the intervertebral discs
Not as hard and rigid as bone, but stiffer and less flexible than muscle
Supports surrounding structures
Helps define and maintain the shape of an area
Provides smooth surfaces, enabling tissues to move smoothly
