Systems Of The Human Body -Skeletal- (Lecture 2) Flashcards
Systems of the human body
Skeletal system
Muscular System
Nervous System
Skin and Fascia
Cardiovascular System
Lymphatic System
Bones of head, neck, and trunk
~80 bones
Axial Skeleton
Bones of limbs
~126 bones
32 in upper limb
31 in lower limb
Appendicular skeleton
Tissue that connects, separates, and supports all other tissues in the body
Connective tissue (type of cartilage)
Form of connective tissue, because of no blood supply, much harder to heal
~~Bones heal faster then ligaments!
Avascular (no blood supply)
Blood supply
Vascular
Where 2 bones come together
Articulations
Function of Cartilage
Support smooth surface for bone articulations
Enable growth and development for long bones
Type of cartilage - ear and larynx
Elastic
Type of cartilage - ends of bone, epiphysial plate (growth plate), in noes and and airways, costal cartilage
Hyalin (articular)
Type of cartilage - meniscus, discs in spine, pubic symphysis
Fibrocartilage (Has lots of fibres within it)
Get bigger in response to stress (ex, working out)
Hypertrophy
Get smaller in response to chronic uploading
Atrophy (no growth)
Bones are either ( ) or ( )
Compact or spongy
Why does bones have a tremendous ability to heal if fractured?
They have a rich blood supply
