THE SKELETAL SYSTEM

SKELETON SECTIONS

• The body is made up of two sections of bones: Axial & Appendicular
• Functions of different bones
• The roles bones have in our Body

AXIAL

• The axial has three major sections in the body,
• They are the skull, the vertebral and the rib cage
• The Axial's protectant support your vital organs
• but it also carries other body parts.

APPENDICULAR

• This consists of bones of the upper
• And lower limbs, your shoulder and pelvis

BONES

• Through exercising your bones will naturally become stronger
• Having a bad posture can put an unnecessary strain on the bones
• There are five different types of bones they are:
• Short Flat
• Long Irregular and sesamoid

LONG BONES

• These bones are cylindrical
• There primary function is acting as levers
• They only pull on muscles and never push!
• There vital role is producing red blood cells
• Femur, metatarsals and phalanges

SHORT BONES

• These bones are usually short and compact in nature
• They are more often then not equal in length and width
• They are designed to with hold strength and weight-bearing
• Carpels and tarsals

FLAT BONES

• These bones offer protection to your vital organs of the body
• Usually provide suitable sites for the muscle to attach
• ( the origins of muscle often attaching to them)
• Scapula, cranium, sternum, ribs

IRREGULAR BONE

• Named irregular due to unique and odd shape
• A complex and individual bone
• Difficult to classify them because of varied functions
• One of these functions is protection.
• Vertebral, sacrum, mandible

SESAMOID BONE

• These bones have special functions
• They ease the joint movement and resist friction and compression
• Normally develop in the tendon
• Covered with a layer of articular cartilage
• Patella
