The study of anatomy and physiology assumes and describes a healthy body. Select the description below that does NOT explain why this approach is useful.Study of a healthy body is less intimidating and more familiar to new students.One of the descriptions below is from the perspective of physiological study, the rest are from an anatomical perspective. Select the description below that comes from physiological perspective.The contraction of smooth muscle in blood vessels (vasoconstriction) can reduce the flow of blood through the vessel.Anatomical position is important becauseit allows a common point of reference for body position to help communicate anatomical relationshipsPositive feedback differs from negative feedback becausepositive feedback tends to enhance the triggering stimulus while negative feedback tends to return the body to a homeostatic balance or "ideal" levelGenerally, what is the result of the negative feedback process?to maintain homeostasisWhen 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 apositive feedbackSome 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.receptorYou are told to take an axillary temperature on a small child. You will place the thermometerin the armpitA structure that is composed of two or more tissue types that work together to perform specific functions for the body is a(n) ________.organThe anatomical position is characterized by all of the following EXCEPT ________.palms turned posteriorlyA good example of a positive feedback mechanism would beenhancement of labor contractionsWhich of the following describes a parasagittal planeany sagittal plane except in the midlineHomeostasis is the condition in which the body maintainsa relatively stable internal environment, within limitsHomeostasis is the condition in which the body maintainsa relatively stable internal environment, within limitsHomeostasis is the condition in which the body maintainsa relatively stable internal environment, within limits
