67. How has the definition and practice of anatomy changed since the days of the early anatomists?
The term anatomy currently refers to the structure of an organism. The early anatomists used the term to
describe the actual dissection of an organism, including the cutting of parts and the separating of tissues. Over
time, however, the word anatomy has evolved to encompass a field of study that now includes many
subspecializations: for example, applied anatomy, descriptive anatomy, gross anatomy, developmental
anatomy, pathological anatomy, and so forth.
68. What languages form the basis for the terminology used to discuss anatomy, and what purpose do these languages still
serve?
Anatomical terms for body parts and tissues are primarily based on Greek and Latin. These languages were
once universally used by early anatomists and medical practitioners. Today, anatomical and medical terms are
still based on their ancient Greek and Latin roots.
69. What are the three major building blocks of the body? Briefly describe the role of each.
The three major building blocks of the body are:
1. Organs: Collections of specific tissues that are organized into structures that are specialized to perform
particular functions. Examples of organs include the kidneys, the heart, the liver, and the lungs.
2. Tissues: Collections or groups of similar cells that are specialized to perform specific functions. The four
types of tissue include:
Epithelial tissue: refers to the outer or superficial layer of mucous
membrane and the cells constituting the skin.
Connective tissue: probably the most complex of the categories of
tissues, because it is specialized for the purposes of support. Connective
tissue varies as a function of the intercellular material (matrix)
surrounding it.
Muscular tissue: consists of voluntary (striated), involuntary (smooth),
and cardiac muscle.
Nervous tissue: specialized for communication.
3. Systems: Combinations of organs that perform specific functions. In other words, systems of the body are
groups of organs with functional unity. Organs can belong to more than one system. Examples of systems
include the muscular system, the skeletal system, the respiratory system, the digestive system, the
reproductive system, the urinary and endocrine systems, and the nervous system.
70. Why are the definitions of the systems of speech primarily a convenience for discussing speech science?
Defining the systems of speech is only a convenience, because none of the four systems operate in isolation.
To produce the sounds of speech, all of the systems of speech must operate together in a highly integrated
manner. The science of speech is extremely complicated, and defining the systems of speech simply makes it
