Discuss the fossil finds at Dmanisi in terms of their morphology and in terms of the information they provide about the dispersal of hominids out of Africa.

1. Discuss and decide upon characteristics that define each of the following broad groups

(domains, kingdoms) of organisms in order to attempt to define these major groups of life

on the planet. Although many characteristics may overlap from one group to the next,

attempt to define some traits that could be used to definitively (exclusively) place an

organism into a specific group. Finally, for each, what would the small subunit ribosomal

rRNA gene sequence tell us?

Viruses

Bacteria

Archaea

Protists (algae, protozoa)

Fungi

Animals

Plants

2. For the previous groups, which include representatives of ones that live as part of the

“human ecosystem”? Provide some examples of each and where they can be found,

including both those that are part of our normal microbiota (i.e., not pathogens) and some

that are.

3. Considering the above and what we’ve covered about these groups of organisms,

identify some structures/processes that hypothetically could be used to inhibit or kill

different types of pathogens without (hypothetically, at least) harming the human host.

4. Consider the microbial world. Which has a greater impact or importance – pathogens,

or benign microbes? Explain, giving examples.

5. A number of antibiotics target the bacterial 70S ribosome, exploiting structural

differences from the 80S ribosome found in humans and other eukaryotes. Although

effective at killing bacteria, these drugs can still have some toxicity to humans. In the

context of the endosymbiotic theory of evolution, provide a hypothesis as to why this

might be.

2260 A&P 1 Lecture - Unit 1

Beware! ANYTHING within the assigned readings or discussed in lecture is fair game whether it is part of this list or not!!

What is the study of Anatomy? Provide an example of an anatomical study.

What is the study of Physiology? Provide an example of a physiological study.

List the characteristics of living things and briefly discuss them.

Compare/Contrast sections and planes.

What are the distinguishing characteristics of the anatomical position?

Practice placing a section through a location in the body and then determine what structures would be made visible by that section in that location. For example if a coronal (frontal) section were made in the thoracic region (would be able to see both lungs, the heart, depending on the exact location of the cut, maybe the esophagus and /or the trachea)

Practice the directional terms using them to describe the locational relationship between two body regions (use the technical terms for those body regions, (i.e. if the original post used __ is superior to blank, the opposite would be ___ is inferior to __).

Distinguish between the nine abdominal regions and four quadrants and indicate what major organ(s) would be found deep to that region or quadrant.

Why is it important to study the language of anatomy and physiology if one is going into the medical field?

Define homeostasis. What thing (or things) in our body maintains homeostasis? And what regulates those "things"?

What is the likely result if homeostasis is not maintained?

13. What are the components of feedback mechanisms? What is the function of each component?

14. Discuss negative feedback mechanisms. Give a specific example of one.

Consider/review the important inorganic molecules discussed in chp 2 and describe their importance in the human body.

Distinguish between acids and bases. Which of these will have relatively more free H+ ions?

What is the pH range of an acid? Of a base? What would be the pH value of a solution where the number of H+ ions = OH- ions?

What are the states of acidosis and alkalosis with reference to blood pH values?

Consider/review the important organic molecules discussed in chp 2 and describe their general importance in the human body.

Distinguish between solvent and solute.

Discuss the term osmolarity.

Consider/review the four types of lipids and discuss their individual function in the human body. Lipids are not composed of monomers but they do have “building blocks”, what are these building blocks?

What are the "building blocks" or monomers (looking for a group or class name) of a carbohydrate polymer? Name the five (5) types of carbohydrate monomers.

When two of these carbohydrate monomers are bonded together what "class" of carbohydrate is formed? What are the types of this "class"? What is the source (food) for each of these?

When three or more of these monomers are bonded together they form which "class" of carbohydrate? Which one of these stores excess carbs in animals (mainly in the liver)? Which one stores excess carbs in plants? And which one is indigestible by the human gut, but is important because it provides "bulk" in the form of fiber and helps keep fecal matter moving in the intestines?

What is the monomer of nucleic acids?

Briefly describe deoxyribonucleic acid including its general function.

Briefly describe ribonucleic acid including its general function.

What are the monomers of proteins? What kind of bond holds the monomers together?
