d) all of the above
answer
The correct answer is D. The receptor receives information from the internal environment, the command center receives and processes the information, and the effector responds, opposing or enhancing stimulus. (1.4c)
question
True or False
Homeostasis is maintained primarily via positive feedback mechanisms.
a) True
b)False
answer
the answer is b) False, homeostasis is maintained through negative feedback mechanisms. (1.4c)
question
Which of the following statements is the most correct regarding homeostatic imbalance?
a) Positive feedback mechanisms are overwhelmed
b) The internal environment is becoming more stable
c) It is considered the cause of most diseases
answer
The correct answer is : C) Since most diseases involve the disruption of normal homeostasis, a homeostatic imbalance results in a disease. (1.4c)
question
Which of the following statements best describes homeostasis?
a) keeping the body in a fixed and unaltered state.
b) dynamic aquarium.
c)maintaining a near constant internal environment.
d) altering the external environment to accommodate the body's needs.
answer
the correct answer is C, homeostasis is the process by which the body maintains near constant environments [ 2 c]
question
Which of the following features of systems is unlikely to lead to a stable homeostasis systems?
a) Negative feedback
b) Positive feedback
c) Redundancy
d) Complexity
answer
The correct answer is B, because positive feedback is rare and it tends to produce unstable system [ 2 c]
question
__________________ is a form of homeostasis.
a) sweating
b) eating
c) drinking
d) shivering
answer
The correct answer is A, homeostasis is the maintenance of body's conditions. So, by sweating you are getting rid of the heat and water which are wast product. [ 2 c ]

A) Forearm
B) Arm
C) Hand
D) Inferior arm
E) Lower arm
answer
The correct answer is A) Foreman
question
Which of these directional terms are paired most appropriately as opposites?
A) Anterior and Inferior
B) Medial and Proximal
C) Distal and Lateral
D) Superior and Posterior
answer
The correct answer is D) Superior and Posterior
question
In the anatomical position, the arms are __________ to the chest. (5)
A- Medial
B- Lateral
C- Superior
D- Distal
answer
The correct answer is B. Lateral means away from the midline of the body. Therefore, in the anatomical position, the arms are lateral to the chest.
question
In the anatomical position, palms face anteriorly. (5)
A- True
B- False
answer
The correct answer is A. This is true. In the anatomical position, the palms face anteriorly (ventrally), meaning they face toward or at the front of the body.
question
Which of these is not true regarding the anatomical position? (5)
A- Thumbs pointed laterally
B- Body erect
C- Feet together
D- Arms at sides
answer
The correct answer is C. In the anatomical position, feet should be slightly apart.
question
(8) Patient is experiencing dull pain near the navel that becomes sharp as it moves to the lower right abdomen. High fever and an inability to pass gas. The patient will need a surgery what type of and where will the surgery need to be performed?
A. upper right quadrant appendectomy
b. lower right quadrant rhinoplasty
c. upper left quadrant rhinoplasty
d. lower left quadrant cerebral endoscopy
answer
a Upper right quadrant. appendectomy- removal of the appendix, the person will live just fine but the appendix can burst causing severe internal damage.
question
(8) The spleen is located in which quadrant?
a LUQ
b RUQ
c RLQ
d LLQ
answer
a A left upper quadrant is the spleen location
question
(8) Most of the liver is located in what quadrant?
a LUQ
b RUQ
c RLQ
d LLQ
answer
b Most of the liver is located in the right upper quadrant, the left upper quadrant has a small part of the liver
question
Which component of homeostasis control variables is responsible with making adjustments to the body using negative or positive feedback?
a organelles
b control center
c nervous system
d effector
answer
d The effector is a tissue or an organ that acts to make necessary changes throughout control mechanisms (negative and positive feedback) which are needed to maintain homeostasis. (03c)
question
Which part of the brain is the control center responsible with perpetuating the body's balance known as homeostasis?
a frontal lobe
b Wernicke area
c cerebellum
d hypothalamus
answer
d Hypothalamus helps to reduce or enhance most of the body's processes, not limited to the most important ones like the heart rate, blood pressure, body temperature, thirst, appetite, sleep cycles, and production of hormones. (03c)
question
Which of the following activities does not produce a negative feedback mechanism that maintain homeostasis?
a Increased Breathing Rate
b Blood clotting
c Control of blood sugar
d Regulation of blood pressure
answer
b This is a positive feedback mechanism. When a blood vessel is damaged platelets start building up at the site, and by releasing several chemicals they will attract more platelets which will release more chemicals, then more platelets will perform the initiation of a blood clot. (03c)
question
(8) The appendix is located in which quadrant?
A. RUQ
B. RLQ
C. LUQ
D. LLQ
answer
The correct answer is
B. right lower quadrant
question
True or False
Homeostasis means controlling variables to maintain a constant external environment (2)
answer
False - Because it control the variables to maintain an internal environment
question
Which two organ systems are especially maintained by Homeostasis? (2)
answer
Endocrine System
Nervous System
question
Homeostatic control variables effect homeostasis what three components do these involve? (2)
answer
Receptor - Responds to stimulus affecting variable
Control Center - determines variable set point
Effector - reduces or enhances stimulus to go back to normal
