FUNCTION OF BONE & SKELETAL
SYSTEM

Support

Serves as the structural framework for the body & providing attachment points for the tendons of
most skeletal muscles

Protection

Protects the most important internal organs from injury

E.g. cranial bones protect the brain, vertebrae (backbones) protect the spinal cord, & the rib cage
protects the heart & lungs

Assistance in movement

Most skeletal muscles attach to bones; when they contract, they pull on bones to produce
movement

Mineral homeostasis (storage & release)

Bone tissue stores several minerals , especially calcium & phosphorus, which contribute to the
strength of bone

Blood cell production

Within certain bones, a connective tissue called red bone marrow produces red blood cells, white
blood cells, & platelets, a process called haematopoiesis

Triglyceride storage

Yellow bone marrow consists mainly of adipose cells , which store triglycerides

DIVISIONS OF SKELETAL SYSTEM

The adult human skeleton consists of 206 bones,
most of which are paired
