Question
Chapter 6, Problem 1SRQ
Summary Introduction
Introduction: The blood is the major fluid that circulates to all parts of the body. The blood is made up of several types of cells. Red blood cells, white blood cells, and thrombocyte are some of the cells that constitute the blood.
Expert Solution & Answer
Answer to Problem 1SRQ
Correct answer: Erythrocyte is an anuclear and biconcave disk-like cell. Therefore, option a. is correct.
Explanation of Solution
Reason for the correct answer:
Erythrocytes are commonly known as red blood cells. They are found in the blood and they get the name due to the presence of hemoglobin that gives them their characteristic red color. The red blood cells lack nucleus and are biconcave disk in shape when viewed under the microscope.
Option a. is given as “Erythrocyte”
Erythrocytes lack a nucleus and their shape is biconcave disk. Hence, option a. is correct.
Reasons for the incorrect answers:
Option b. is given as “Granulocyte”.
Granulocytes are leukocytes and contain a nucleus. Therefore, option b. is incorrect.
Option c. is given as “Leukocyte”.
Leukocytes are also known as white blood cells and contain a nucleus. Therefore, option c. is incorrect.
Option d. is given as “Thrombocyte”.
Thrombocytes contain a nucleus. Therefore, option d. is incorrect.
Hence, options b., c., and d. are incorrect.
Conclusion
Erythrocytes lack a nucleus and their shape is biconcave disk.

- Topic: What does EMG activity look like and how does this change with increasing intensity of muscle contraction? What does the relationship between the biceps RMS EMG amplitude and contraction intensity suggest? If contraction of one skeletal muscle fibre produces electrical activity (i.e. EMG activity), what does the above relation imply? There are several factors that influence tension produced by a whole skeletal muscle. Which 2 factors are preliminary influencing the relationship between the Biceps RMS EMGamplitude and contraction intensity in the current task?
