BN507 MODULE 2 EXAM QUESTIONS AND ANSWERS
WITH COMPLETE SOLUTIONS GRADED A++ LATEST
UPDATE
Cartilage
Tough yet flexible connective tissue composed of extracellular matrix which gives great
resilience
Types of cartilage (3)
Hyaline, elastic and fibrocartilage
Hyaline cartilage
Most abundant type, support that reduces friction but has some resilience
Location of hyaline cartilage
Nose, respiratory cartilage, costal cartilage
Elastic cartilage
Contains numerous elastic fibers in the ECM , capable of maintaining its original shape,
even after distortion
Location of elastic cartilage
External ear and epiglottis
Fibrocartilage
Consists mainly of collagen fibers allowing it to resist compression, compression forces
are high
, Location of fibrocartilage
Between vertebrae, between pubic bones and pads within knee joints
Functions of the skeletal system (5)
Support, organ protection, lever for movement, mineral storage and red blood cell
production
Osteogenic cells
Maintained stock of cells undergoing continuous mitosis
Each mitotic division results in 2 daughter cells 1 becomes an osteoblast and 1 remains
as an osteogenic cell that will continue the mitosis process
Osteoblasts
Bone building cell produce and lay down osteoid, when the cells are active they take
calcium out of the blood to incorporate into the ECM of bone
Osteocytes
Play a number of roles in maintenance of bone, communicating with eachother and the
bone cells to coordinate bone building and remodelling, particularly in response to
mechanical stress
Osteoclasts
Phagocytic cells that break down theECM of bone, in the process of bone reabsorption
they release mineral salts into the blood
Bone structure
Compose of multiple tissue types and have blood and nerve supply
External and internal surfaces are lined with dense connective tissue (contain the
