After for the cell, which would include whether

After reading through the chapter, referencing all of the
sources available, and testing my skills through the study guide, I have
gathered several terms that I struggled with through my process. All the terms
come from the same source, our required class book which is included in the
references section below. For each term, I will define the term in my own
words, which will enable me to understand the word and more efficiently recall
it in the future:

Variables, when used in reference to
homeostasis, are surroundings that can change for the cell, which would include
whether the environment is too warm or cold; how much fluid there is; and also
what is in the fluid. Cells use their surrounding environment to function
normally, which these conditions can fluctuate within a normal range.

Positive-feedback mechanisms are situations in
which the body creates a larger gap between the normal and the level in which
the stimulus caused. This response allows the body to return to its normal set
point by increasing the stimulus. This is different from the negative-feedback
system, which is how our body maintains correct body temperature. If the
temperature outside our body is rising, our skin will note a change, and notify
our brain that something isn’t right. In this case, that the temperature is
increasing and we need to do something in order to keep our cells happy. When
the brain interprets the message, and agrees that something needs to be done,
it sends a message to a cell that can do something about this, a sweat gland.
The sweat gland will release moisture, to cool the skin off, allowing the skin
to tell the brain the skin is no longer out of its normal.

Anatomical position is the static position that
is used when making any references when describing the body. The position is
standing, with the head facing forward, palms up, with the arms relaxed at the

Anterior and ventral are the same, as anterior
is the front and ventral means belly.

Dorsal and posterior are the same as well, meaning
the back, which is behind us.

The mesenteries are pathways generated by
connecting walls of the peritoneum, in order to allow access for nerves and
blood to the organs, and also to help stabilize the organs. They are either
connected to other organ peritoneum, or anchored to the other lining, (parietal

Responsiveness in reference to the
characteristics of life, means that at the highest level of organization, an
organism adapts to its surroundings in order to survive. In order to survive
the heat, the body may sweat or increase water consumption; if it is cold it
may begin to shiver to generate heat or start burning off food sources within
the body to maintain a survivable temperature.

Organelles are inside of a cell, they are the
molecules that are together to form differently arranged structures that
somehow contribute to the overall function of the cell. Although cells have
similar compositions, they can have different organelles to perform different

Regional anatomy uses sections or grouped parts
of the body in order to study and teach the sections, in order to learn all of
the systems at the same time within that specific subdivision.

The abdominopelvic cavity contains both the
abdominal and pelvic cavity, and is grouped together because there is no actual
separation within the human body. This section does not have access to the
outside of the body, and begins under the diaphragm and ends essentially at the

Although many of these definitions become longer when defined
using different language, this has helped me have a stronger understanding and
be able to define the word if asked from someone outside of the class. Also, by
explaining a positive-feedback mechanism in my own words and then explaining
how that is different using body temperature in a negative-feedback sequence, I
now fully understand the entire concept and have examples to reference.
