the skeletal and muscular systems- skeleton

there are two parts to the skeleton: axial, and appendicular

AXIAL- consists of the skull thoracic girdle, and vertabral column, they are normally fixed and do not provide much movement, more protection of vital organd. e.g ribs protect heart+ lungs, dont move much.

APPENDICULAR: consists of shoulder girdle and upper limbs, these bones provide movement and join to the AXIAL skeleton. the humerus is a part of the appendicular skeleton.

LIGAMNETS- elastic tissue that attatches bone to bone e.g femur to pelvis 
TENDONS- strong tissue that attatches skeletal muscle to bone e.g biceps brachii to humerus
