The Skeleton Flashcards
What do ligaments do?
Create stability
Attach bones to other bones
What do tendons do?
Attach bones to muscles
What is cartilage?
Dense fibrous tissue
What is cartilage useful for/what does it do?
Withstands compression forces
Absorbs shock
Reduces friction at joints
(Often covers the end of bones)
What are the 5 functions of the skeleton?
Attachment and movement
Shape
Storage
Protection
Production
Describe how attachment and movement works with the skeleton
Muscles attach to bones, via the tendons, and pull on them to create movement & act as levers for locomotion
Describe how storage works with the skeleton
Stores vital minerals such as calcium and phosphorus which support growth and development
Describe how the skeleton “protects”
The skeleton protects vital organs such as the skull protecting the brain, the ribcage protecting the heart and lungs
Describe the production aspect of the skeleton
Red marrow within some bones is where red and white blood cells are produced from
Name the three bones that make up the hip complex
Ilium (hip bone)
Pubis (pubic bone)
Ischium (itchy bum bone)
What are the two categories of the skeleton?
Axial
Appendicular
Which part of the body is the axial skeleton?
The central column
It has 80 bones
Lies on the midline
Includes the skull, vertebrae, sternum, and ribs
Which part of the body make up the appendicular skeleton?
The limbs
126 bones
Includes bones of the shoulder girdle inc arms and hands, and of the pelvic girdle, legs and feet.
