ORGANS INSIDE THE BODY

INSIDE A BONE

BONES ARE MADE UP OF: Compact-hard, tough tissue that provides

support and surrounds the spongy bone. Spongy-strong but lightweight tissue, bone

marrow is housed here Bone marrow creates new red blood cells

2 DIVISIONS OF THE SKELETAL SYSTEM

AXIAL SKELETON- consists of the skull, spinal cord, ribs and pelvis.

APPENDICULAR

SKELETON- Includes the arms and legs and main function is to provide movement

TYPES OF JOINTS

Immovable joints- bones of your skull are connected by joints that do not move.

Movable joints- Allows body to bend and move. Joint is surrounded by connective tissue called ligaments. Example- arm moves up and down by a joint called a hinge joint.
