Questions and CORRECT Answers
Skeletal System Functions (6) Support, protection, movement, mineral homeostasis, hematopoiesis, storage
How does the skeletal system perform mineral Stores Ca2+ and P
homeostasis?
How does the skeletal system perform Hematopoiesis? Blood cell production in red bone marrow
How does the skeletal system perform storage? triglyceride storage in yellow bone marrow
Types of skeletal system tissues Bone and cartilage
Types of Cartilage in the skeletal system Hyaline (blue), elastic (green), and fibrocartilage (red)
Types of bone Spongey and compact
Where is hyaline cartilage found? ribs, trachea, larynx, nose, articulations (at end of long bones, epiphyseal plate)
What is the most abundant cartilage? Hyaline
Hyaline cartilage and collagen fibers contains only collagen fibers that are not directly visible microscopically
What does hyaline cartilage provide to bones? Support with flexibility
Hyaline Cartilage cell Chondrocyte
Function of hyaline cartilage supports and reinforces, serves as a resilient cushion, resists compressive stress
What do chondroblast do? produce the matrix for the cartilage cells, and when mature (chondrocytes) lie in
lacunae
Location of elastic cartilage Ears, epiglottis, Eustachian tubes
Elastic cartilage makeup elastin fibers and collagen
Difference between hyaline and elastic cartilage Elastic cartilage has more elastic fibers in matrix
, Function of elastic Cartilage maintain the shape of a structure while allowing great flexibility
Fibrocartilage makeup Collagen fibers, van Gogh appearance
Fibrocartilage location Intervertebral disks, pubic symphysis, knee meniscus
Fibrocartilage function Tensile strength allows it to absorb compressive shock, great pressure with some
flexibility
