Bio-180 Unit 2 Exam 2, The Skeletal
System questions and verified answers
(MULTIPLE CHOICES) AND
RATIONALES|GET IT 100% ACCURATE!!
Functions of the skeletal system - CORRECT ANSWERS support, protection, movement,
storage, blood cell production
long bone - CORRECT ANSWERS longer than they are wide
short bone - CORRECT ANSWERS carpals and tarsals
flat bone - CORRECT ANSWERS thin and curved bone; serves as a point of attachment for
muscles and protects internal organs
irregular bone - CORRECT ANSWERS bone of complex shape; protects internal organs from
compressive forces
sesamoid bone - CORRECT ANSWERS small, round bone embedded in a tendon; protects the
tendon from compressive forces
Function of compact bone - CORRECT ANSWERS provides great strength and support
Function of spongy bone - CORRECT ANSWERS cross bracing, reduce weight, support and
protect marrow
Function of articular cartilage - CORRECT ANSWERS reduces friction and absorbs shock
, Function of periosteum - CORRECT ANSWERS Fibrous membrane covering attached by fibers
Enter into bone allowing nerves, blood/lymphatic vessels top pass through it
Function of endosperm - CORRECT ANSWERS a source of reserve materials and food for the
developing embryo
Function of medullary cavity - CORRECT ANSWERS (long bone) store marrow, involved in the
formation of red and white blood cells
Function of yellow marrow - CORRECT ANSWERS store adipose tissue
Function of red marrow - CORRECT ANSWERS blood cell production
Function of epiphysis - CORRECT ANSWERS strengthens joint areas because it provides a
larger surface area and provides attachment for tendons/ligaments
Function of diaphysis - CORRECT ANSWERS Provide strong support without cumbersome
weight
Metaphysis (long bone) - CORRECT ANSWERS Area where the epiphysis and diaphysis meet
epiphyseal line (growth plate) - CORRECT ANSWERS cartilage between epiphysis and
diaphysis, where bone grows in length
nutrient foramen - CORRECT ANSWERS Opening through compact bone, allows passage of
artery into medullary cavity
