Take a 20-minute walk or ride (or do anything that involves some movement) and think about the organ systems described in the lecture. Take a break from your activity, and note the following:

• Name 4 organ systems that you feel are working during your activity.

• What roles are 2 of these systems playing in your activity?

• What is one system that you know is working but you’re not feeling it work?

• Name 1 way that your body is maintaining “homeostasis” during your activity.

Describe the electrical activity of the heart to include the electrical activity of the noncontractile auto rhythmic cells (pacemaker cells) and the depolarization and repolarization of the myocardium.

Discuss age-related changes that occur in the remainder of the axial skeleton

Starting with a fatty acid located in the cytosol of the cell, explain “mechanistically” how an iron deficiency may result in reduced acetyl CoA production from beta oxidation of palmitic acid

Describe the social and public health (PH) challenges that need to be addressed to improve the health of women in low income countries

1. Describe the purpose of osteological landmarks (process, fossa, foramen). Identify 1-2 examples of each.

Which of the following statements is(are) true? (Check all that apply)

In eukaryotes, multiple genes can be expressed simultaneously by

A transcriptional regulator that activates expression of additional transcriptional regulators that induce production of a particular cell type or organ is called a

he control of a gene product’s levels or activity after transcription has taken place is called

compare and contrast the mucosa's between the esophagus and small intestine

pick two of the nervous system pathologies to discuss from the list below.  

For each selected pathology, you should provide the following information: an explanation of the underlying functional or structural deficit present in the condition, predicted deficits based on your knowledge of the normal function and structure of the nervous system (these are educated guesses based on your understanding of nervous system function), and an explanation of at least three signs/symptoms that are seen with this condition (based on sources found during research you have conducted into the chosen conditions). Your discussion MUST include an explanation describing how the deficit produces the observable signs/symptoms AND a statement describing how your chosen conditions affect homeostasis within the body.

Choose two of the following nervous system pathologies to discuss:

Parkinson’s disease

Tay-Sachs disease

Multiple sclerosis

Polio

Hydrocephalus

Guillain-Barré syndrome

Bell’s palsy

State the important distinction between the terms 'serving size' and 'portion'. why do you think that portion sizes of many foods have generally gone up for many people? What might be at least one reason (that might even sound fairly logical) that foods with higher energy densities, and sometimes correspondingly lower nutrient densities, are eaten with greater frequency in many people's diets? .

. If the curve for sufficiency of intake of a given nutrient were narrower (tighter) and the distance between the UL and both the RDA and EAR thus less, how would this impact an individual's approach to attaining an adequate, but not excess, amount of such nutrient?
