Normal Temperature? Normal Pulse Rate? Normal Blood Pressure? Normal Respiratory Rate? Normal SPO2? What is cellular regulation? Characteristics of normal cells: Characteristics of benign cells: Characteristics of cancer (malignant) cells: 98.6 degrees F 60-100 beats per minute 120/80 mmHg 12-20 breaths per minute 95-100% The genetic and physiologic processes that control cellular growth, replication, differentiation, and function to maintain homeostasis. All of the steps of cellular regulation are resulted from gene inter￾actions. None or slow cell division Distinct, recognizable appearance SMALL nuclear-cytoplasmic ratio Differentiated function Tight adherence Nonmigratory Orderly and well regulated growth Continuous or inappropriate cell division Specific morphology Smaller nuclear-cytoplasmic ratio Specific differentiated functions Tight adherence Nonmigratory Orderly growth (Growth continues past the appropriate time or occurs in the wrong place 'indicates an error in cellu￾lar regulation') Grows by expansion, BUT DOES NOT INVADE Rapid or continuous cell division Anaplasia: loss of specific appearance of parent cell Larger nuclear-cytoplasmic ratio Specific functions are lost Loose adherence Migration: invade tissues close by and MDC Exam 1 Review Questions And Answers 100% All Correct 2 / 6 What is metastasis? T or F? Even though the tumor is now in another organ, it is still cancer from the original altered tissue. What is a primary tumor? What is a secondary tumor? What is the TNM system? T or F? Cancer cells that barely resemble the mature tissue from which they arose that are aggressive and spread rapidly are "high-grade" tumors. What is low-grade cancer? Why is tumor grading needed? What are external factors that cause cancer? more remote from origin Abnormal chromosomes When cancer cells move from the primary location by breaking off from the original group and establishing remote colonies. True original group of cancer cells or tumor caused by carcinogenesis Cancerous tumor cells that move from the primary location by breaking off from the original group and establishing remote colonies. The Tissue, Node, Metastasis system **Not useful for leukemia or lymphomas** True; poor differentiation less malignant cells that are "well differentiated" and more closely resemble the tissue from which they arose. some cancers are "more malignant" than others varying in their aggressiveness and sensitivity to treatment. Environmental carcinogens: Chemical, Physical, and Viral -Chemical: everyday chemicals and drugs (tobacco) -Physical: radiation and chronic irritation and tissue trauma (Skin cancer higher in adults with burn scars or other severe skin injuries)
