BSC 2085 EXAM 2 Question and Answer
Grade A+ 100% Correct Questions
and Answers
• Skeletal System Functions (6) -✓✓Support, protection, movement, mineral
homeostasis, hematopoiesis, storage
• How does the skeletal system perform mineral homeostasis? -✓✓Stores Ca2+
and P
• 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
• Compact bone is arranged in what? -✓✓Osteons
• What are osteons? -✓✓repeating structural units of compact bone
• What do collagen fibers do in compact bone? -✓✓in adjacent lamella run in
opposite directions to withstand torsion
• Location of osteons -✓✓outer rim of compact bone
• Cells in compact bone -✓✓Osteoclast, osteoblast, osteocytes
• Osteocytes -✓✓Maintain bone matrix, located in lacunae of compact bone and in
trabeculae of spongey
