BIO 1012 Week 6 Assignment 2 Skeletal Muscle Physiology


1. To define these terms used in describing muscle physiology: multiple motor unit summation, maximal stimulus, treppe, wave summation, and tetanus.

2.       To identify two ways that the mode of stimulation can affect muscle force production.

3.       To plot a graph relating stimulus strength and twitch force to illustrate graded muscle response.

4.       To explain how slow, smooth, sustained contraction is possible in a skeletal muscle.

5.       To graphically understand the relationships between passive, active, and total forces.

6.       To identify the conditions under which muscle contraction is isometric or isotonic.

7.       To describe in terms of length and force the transitions between isomet- ric and isotonic conditions during a single muscle twitch.

8.       To describe the effects of resistance and starting length on the initial velocity of shortening.

9.       To explain why muscle force remains constant during isotonic shortening.

10.   To explain experimental results in terms of muscle structure.


Match each of the following descriptions with a key equivalent, and record the key letter or term in front of the description.
Indicate the following body areas on the accompanying diagram by placing the correct key letter at the end of each line.

Classify each of the terms in the key of question 2 above into one of the large body regions indicated below. Insert the appropriate key letters on the answer blanks.

Describe completely the standard human anatomical position


Several incomplete statements are listed below. Correctly complete each statement by choosing the appropriate anatomical term from the key. Record the key letters and/or terms on the correspondingly numbered blanks below.

Correctly identify each of the body planes by inserting the appropriate term for each on the answer line below the drawing.

Name each of the three different planes represented by the drawings of the sectioned kidney.

Correctly identify each of the nine areas of the abdominal surface by inserting the appropriate term for each of the letters indicated in the drawing.
