APHY 101 Final Exam Questions and Answers
Question 1
What is the function of actin and myosin?
Correct Answer
According to the sliding filament theory of muscle contraction, the myosin crossbridge attaches to the binding site on
the actin filament and bends, pulling on the actin filament; it then releases and attaches to the next binding site on the
actin, pulling again
Question 2
CIRCUMDUCTION
Correct Answer
moving the distal end of a limb in a circle and the proximal end is stationary
Question 3
Neutral solution
Correct Answer
pH 7; indicates equal concentrations of H+ and OH-

,Question 4
What are hydrogen bonds?
Correct Answer
Weak attraction between positive end of one polar molecule and negative end of another polar molecule; formed
between water molecules
Question 5
Define atoms
Correct Answer
smallest particle of an element; basic unit of matter
Question 6
What are lipids?
Correct Answer
Primarily used to supply energy for cellular activity. Lipids are insoluble in water and include fats, phospholipids, and
steroids.
Question 7
Epiphysis
Correct Answer
Expanded ends of bones that form joints with adjacent bones

,Question 8
What is a pH scale?
Correct Answer
represents the concentration of hydrogen ions [H+] in solution
Question 9
What is the function of the Temporal Lobe?
Correct Answer
receives auditory information;
important for audition & language processing
Question 10
myosin
Correct Answer
makes up thick filaments
Question 11
Stratified Columnar Epithelium
Correct Answer

, Question 12
Distinguish among osteocytes, osteoblasts and osteoclasts.
Correct Answer
Osteocytes- mature bone cells
Osteoblasts- bone-forming cells
Osteoclasts- cell that erodes bone
Question 13
Which are components of thin filaments?
Correct Answer
actin, troponin, tropomyosin
Question 14
3 types of cartilage
Correct Answer
Hyaline cartilage, elastic cartilage, fibrocartilage
