All functions of the body can be interpreted as the effects of cellular activity. The hypothetico-deductive method is common in physiology, whereas the inductive method
is common in anatomy
.
Are the simplest body structures considered alive?
What is a
cell
? No cells– no life! The simplest structure considered to be alive.
Who was the first to publish accurate drawings of the body?
In 1543, at the young age of 29,
Vesalius
published his most important work, De Humani Corporis Fabrica Libri Septem (Seven Books on the Fabric of the Human Body), generally known as the Fabrica. The Fabrica is the most famous anatomy book ever written and also the first book on human anatomy to be reasonably accurate.
Is homeostasis and occupying space both unique characteristics of living things?
Homeostasis and occupying space are
both unique characteristics
of living things. Positive feedback helps to restore normal function when one of the body’s physiological variables gets out of balance.
What are the three common components of a feedback loop?
The three common components of a feedback loop are
the receptor (sensor), the control center (integrator or comparator), and effectors
. A sensor, or commonly known as a receptor, detects and transmits a physiological value to the control center.
What is an example of a feedback loop?
Feedback loops are biological mechanisms whereby homeostasis is maintained. … Some examples of positive feedback are
contractions in child birth and the ripening of fruit
; negative feedback examples include the regulation of blood glucose levels and osmoregulation.
How is a positive feedback loop normally stopped?
In these cases, the positive feedback loop always
ends with counter-signaling that suppresses the original stimulus
. A good example of positive feedback involves the amplification of labor contractions. The contractions are initiated as the baby moves into position, stretching the cervix beyond its normal position.
When was the first human body dissected?
3rd century B.C.
The first documented scientific dissections on the human body are carried out as early as the third century B.C. in Alexandria.
Who is known as father of anatomy?
As Hippocrates is called the Father of Medicine,
Herophilus
is called the Father of Anatomy. Most would argue that he was the greatest anatomist of antiquity and perhaps of all time.
What discoveries did Leonardo da Vinci make about the human body?
Leonardo made many important discoveries. For instance, he produced
the first accurate depiction of the human spine
, while his notes documenting his dissection of the Florentine centenarian contain the earliest known description of cirrhosis of the liver.
What is the difference between gross anatomy and microscopic anatomy?
“Gross anatomy” customarily refers to the study of those body structures large enough to be examined without the help of magnifying devices, while microscopic anatomy is concerned with the
study
of structural units small enough to be seen only with a light microscope. Dissection is basic to all anatomical research.
Does positive feedback help restore normal function?
Homeostasis and occupying space are both unique characteristics of living things. Positive feedback
helps to restore normal function when one of the body’s physiological variables gets out of balance
.
What is the study of body functions called?
Physiology
is the study of how the human body works. It describes the chemistry and physics behind basic body functions, from how molecules behave in cells to how systems of organs work together. … Most of physiology depends on basic research studies carried out in a laboratory.
Which of the following describes represents a property exclusive to all living things?
Which of the following describes or represents a property exclusive to all “living” things?
They take in molecules from the environment and chemically change them into molecules that form their own structures.
Why is precise spelling important in anatomy?
Discuss why precise spelling is important in anatomy and physiology.
A patients life can depend on precise spelling
. For instance a muscle can be mistaken for a bone or a bone mistaken for the portion of an organ. Many patients have died simply because of tragic written and oral miscommunication in the hospital.
What is a negative feedback loop in anatomy?
In negative feedback,
the body works to correct a deviation from a set point, it tries to get back to normal
. Examples include body temperature, blood pressure, blood oxygen levels, and thirst sensation. … Examples include blood clot formation, lactation, contractions during childbirth, and fever.
