Anatomy and Physiology TEST #1 Questions and Answers You are told to take an axillary temperature on a small child. You will place the thermometer ________. -Answer -in the armpit You are asked to draw blood from the median cubital vein. You will search for this vein in the ________. -Answer -anterior side of the elbow Anatomical position is important because _______________. -Answer -it allows a common point of reference for body position to help communicate anatomical relationships Anabolic reactions are chemical reactions on the body that build things, make them bigger or more complex. Catabolic reactions break things down making them smaller or less complex. If the rate of anabolic reaction in the body is much faster than the rate of catabolic reactions which of the following necessary life function will be accomplished? -
Answer -growth The thoracic cavity contains the _____________. It is found ______________ to the vertebral cavity. -Answer -heart and lungs; anterior It is wise to study anatomy alongside with physiology because ________. -Answer -
physiology is only explainable in terms of the underlying anatomy Choose the following statement that is not completely correct regarding serous membranes. -Answer -Visceral pericardium covers the outer surface of the heart, and parietal pericardium lines the inner walls of the heart When a baby suckles at its mother's breast the stimulus at the breast is sent to the mother's brain (a region called the hypothalamus). The brain responds by releasing hormones to stimulate the production and the ejection of milk from the breast. This helps the newborn to receive nourishment and encourages more suckling. This example is best described as a ________. -Answer -positive feedback The study of large body structures, visible to the naked eye, such as the heart is called ________ anatomy. -Answer -gross In which body cavities are the lungs located? -Answer -pleural, ventral, and thoracic Which of these is not part of the dorsal cavity? -Answer -thoracic cavity Select the most correct statement -Answer -The immune system is closely associated with the lymphatic system The body cavities that protect the nervous system are located in the ______________ cavity. -Answer -dorsal One of the functional characteristics of life is excitability or responsiveness. This refers to _______________________. -Answer -sensing changes in the environment and then reacting or responding to them Homeostasis is the condition in which the body maintains _________________. -
Answer -A relatively stable internal environment, within limits Expiration (breathing out) is how the body removes excessive carbon dioxide from the blood. This is an example of ________. -Answer -excretion of metabolic waste Positive feedback differs from negative feedback because ___________. -Answer -
Positive feedback tends to enhance the triggering stimulus while negative feedback tends to return the body to a homeostatic balance or "ideal" level What is a vertical section through the body, dividing it into left and right, called? -
Answer -sagittal Which of the following describes a parasagittal plane? -Answer -Any sagittal plane except in the midline A good example of a positive feedback mechanism would be ___________. -Answer -
enhancement of labor contractions Which of the following are survival needs of the body? -Answer -Nutrients, waste, atmospheric pressure, and oxygen A structure that is composed of two or more tissue types that work together to perform specific functions for the body is a (n) _____________. -Answer -organ Some of the nerve endings in the skin are sensitive to changes in temperature. They are part of a negative feedback mechanism regulating body temperature. These nerve endings represent a (n) _____________ in the negative feedback mechanism. -Answer -
recepto r Play's the following in correct sequence from simplest to most complex: 1. Molecules 2. Atoms 3. Tissues 4. Cells 5. Organs -Answer -2-1-4-3-5 Generally what is the result of the negative feedback process? -Answer -maintain homeostasis
