2025-2026 BRAND NEW ACTUAL EXAM WITH
100% VERIFIED QUESTIONS AND CORRECT
SOLUTIONS
1. To accomplish self-regulation, a highly complex and integrated
|| || || || || || ||
communication control system or network is required. This type of
|| || || || || || || || || ||
network is called a(n) - Correct Answer-feedback control loop.
|| || || || || || || || ||
2. Local control or
|| , intrinsic mechanisms often make use of
|| || || || || || || ||
chemical signals. - Correct Answer-autoregulation
|| || || || ||
3. The impact of effector activity on sensors may be positive or
|| || || || || || || || || ||
negative. Therefore, homeostatic control mechanisms are
|| || || || || ||
categorized as - Correct Answer-organs that are directly influenced
|| || || || || || || || ||
by physiological variables or mechanisms.
|| || || || ||
4. The normal reading or range is called the - Correct Answer-set point.
|| || || || || || || || || || ||
5. Events that lead to an immune response to an infection or the
|| || || || || || || || || || ||
formation of a blood clot are examples of - Correct Answer-positive
|| || || || || || || || || || ||
feedback

6. The concept that information may flow ahead to another process to
|| || || || || || || || || ||
trigger a change in anticipation of an event that will follow is called -
|| || || || || || || || || || || || || ||
Correct Answer-feed-forward.
|| ||
7. Processes for maintaining or restoring homeostasis are known as -
|| || || || || || || || ||
Correct Answer-homeostatic control mechanisms.
|| || || ||
8. Homeostatic Control Mechanisms - Correct Answer-receptor, control
|| || || || || ||
center, effector
|| ||
9. receptor, control center, effector - Correct Answer-List the three basic
|| || || || || || || || ||
components of a feedback system.
|| || || || ||
10. What term describes a signal traveling toward a particular
|| || || || || || || ||
|| center or point of reference? - Correct Answer-afferent
|| || || || || || ||
11. Effectors can be described as - Correct Answer-organs that
|| || || || || || || ||
|| directly influence controlled physiological variables.
