Hondros BIO 117 Exam 2 Verified
100% Correct!!
Shaft of long bone - -diaphysis
-Site of longitudinal bone growth - -epiphyseal disc
-Bone-building cell - -osteoblast
-Site of blood cell production - -red bone marrow
-Tough outer covering of the bone - -periosteum
-Enlarged end of a long bone - -epiphysis
-Cancellous bone - -spongy bone
-Osteon - -haversian system
-Bone-eroding cell that helps in bone marrow remodeling - -
osteoclast
-Hollow center of a long bone - -medullary cavity
-The epiphyseal disc is - -composed of cartilage and is involved
in the growth of long bones
-Osteoclastic activity - -stimulates bone breakdown
-Depression of the red bone marrow - -causes a life-threatening
decline in red blood cells
-Osteoporosis affects the older population, with women being
more affected. Other bone diseases cause a decrease in bone
density. Which hormone could possibly be contributing to this,
what cell is turning on and which cell is turning off? - -Parathyroid
Hormone, turning on osteoclasts, turning off osteoblasts
, -What are all the bones of the Pelvic and Pectoral Girdles? - -
Pelvic Girdle: Sacrum, Coccyx, Pelvic bone (ilium, ischium, pubis)
Pectoral Girdle: Scapula and Clavicle
-If we needed less calcium in the bloodstream, what hormone
would I want to use? What gland does this hormone come from?
What cell does it stimulate? What cell does it inhibit? - -Calcitonin
from the thyroid gland, osteoblasts, and osteoclasts
-What are the bones of the arm? What bone does each articulate
with? What special cartilage can we see at the ends of these
articulating bones? Is this appendicular skeleton or axial skeleton?
- -Humerus (articulates with scapula, radius, ulna), radius
(articulates with humerus, ulna, carpals), ulna (articulates with
radius, humerus, carpals)
Special Cartilage = articular cartilage
Appendicular skeleton
-What are the bones of the leg? What bone does each articulate?
Where would I see synovial fluid? - -Femur (articulates with pelvic
bone, tibia, patella), Tibia (articulates with fibula, patella, talus),
Fibula (articulates with tibia, talus)
Synovial fluid is in the knee joint
-What bones make up the axial skeleton? - -Cranium, Vertebrae,
Rib cage, Pelvic bone
-If someone is suffering from tendonitis, what is inflamed? What
does this structure connect? - -The muscle tendon is inflamed, it
connects muscle to bone.
-What do ligaments connect? - -bone to bone
-What do aponeuroses connect? - -muscle to muscle
