Cockroach v. Human

Both humans and cockroaches are inclusive of Muscle Tissue. Muscle tissue is made up of multiple muscle cells that come together to be arranged in bundles. This structure of bundles that the muscle cells make allow for short and intense contractions to happen throughout the body, to allow many movements, from small to big, to occur in both of these organisms.

Cockroach v. Human

The cockroach and the human are very different in terms of size. The cockroach is much smaller than a human. This structure goes well with its function as the increased human size allows for more complex functions such as talking, thinking on a complex scale, and much more.

Cockroach vs. Human

In the respiratory system of a human, the cockroach has spiracles on its surface due to the fact that it has no lungs.  The way that the spiracles are spread out allow for air to enter the cockroach's body from various points to deliver oxygen straight to the tissues.

However, the human body does have lungs and a circulatory system, therefore, it is sufficient for air to enter the body through the mouth and nose through the trachea alone. The oxygen then goes to the lungs and then to be pumped into the blood and throughout the rest of the body by the heart. This complex system is suitable to a human's larger size.

Anesthetize Cockroach by placing the cockroach on the surface of ice-water

To set up the SpikerBox, we plugged the green cord into the SpikerBox and into my headphone jack so we could record the action potentials onto the SpikerBox app that I downloaded.

# data[].attributes.body
We utilized the "tug" method to pull off the leg of the cockroach.

# data[].attributes.body
Finally, we put the leg on the cork on top of the SpikerBox and place one electrode into the femur and one into the coxa to record the action potentials in the leg.

The little white dots on top of the curve represent the peak of the action potentials being sent through the neurons in our model organisms leg.

The living individual itself - in the case of this lab, we have the cockroaches.  However, other organisms include but are not limited, to me, you, and the sheep that we dissected the eye of. An organism is inclusive of the different levels of hierarchy, which all interact and work together to help the organ function.

# data[].attributes.body
Composed of 2 or more types of tissues with a specific function.

Pictured below is a picture of the sheep eye that we performed a dissection on in the year.  Like a cockroach eye, the sheep eye is composed of 2 or more types of tissues to perform a specific function (seeing).

Another example of an organ would be the brain of a sheep. A brain is an organ that consists of many neurons to help process information sent in from other parts of the body.

The final example of an organ is the stomach of a human. This organ helps in the digestive system, breaking down food into nutrients that the body will later be able to utilize.

Cells are the basic unit of life, all types, sizes, and functions of cells

Tissues are the groups of similar cells with a common function. There are four types of tissues: epithelial, connective, muscle, and nervous.

1. The first cell is a muscle cell and together, many muscles come together to aid in activities such as the movements of the cockroach.  of many cell types.  Together, the cells come together to form muscle tissue.  example, the cockroach would not be able to move legs to crawl out of the beaker without the muscle cells.

2. The second cell present is an adipocyte. Together, many adipocytes come together to form adipose tissue, which holds a primary function in storing fat for energy. For example, in human bodies consist of adipose to store energy for later functions of the body.

3.  The third cell present is a simple cuboidal epithelial cell, which is a cube shape cell often found in the lining of ovaries of ovaries and nephron. Many cuboidal epithelial cells come together in one single layer to form the simple cuboidal epithelium, which is extremely efficient in these areas to secrete and absorb necessary substances (for example, secreting wastes of the fetus out through the mother or nutrients into the fetus) in a human body.

Related organs that a common function (one organ may be part of more than one system).

1. The first organ system we have picture below is the circulatory system of the cockroach. A cockroach, unlike a human, has an open circulatory system that does not include vessels (described more below).

2. The second organ system pictured below is the human digestive system. The stomach is one of the organs in this system and the job of the system as a whole is to break down food into nutrients for the body to use and to dispose the rest as waste.

3. The final organ system picture below is the central nervous system, which includes the brain and spinal cord. The video below explains how the central nervous system works to respond to an outside stimulus.

This level of hierarchy consists of atoms, or the smallest units of matter that participate in chemical equations.

Within the neurons present inside of the cockroach, many chemical substances are present. As pictured in the drawing below, in a resting neuron membrane, there is a surplus of K+ ion within the neuron and a surplus of Na+ and Cl- outside of the neuron's phospholipid bilayer.
