2-1-4-3-5

Atom X has 17 protons. How many electrons are in its valence shell?

7

Which organelle is responsible for processing and packaging proteins destined for export from the cell?

Golgi apparatus

Beta cells in the pancreas produce and secrete the protein hormone insulin. You would expect to see a relatively large amount of which organelles in these cells

Golgi apparatus, rough endoplasmic reticulum

Which of the following organs or structures would be found in the left iliac region?

Intestines

Anatomical position is important because ________.

It allows a common point of reference for a body position to help communicate anatomical relationships

Clinical Question: Your patient is sitting in your office for a pre-operative appointment and asks you why he will be given a saline IV rather than one containing pure sterile water. What is your response?

It is because if pure water was given to you the water would swell the blood cells which may cause the blood cell to burst whereas the saline allows for an equal concentration for your blood cells

In which stage of mitosis do the identical sets of chromosomes line up along the midline or equator of the cell?

Metaphase

Myocardium (cardiac muscle tissue) must rhythmically contract for a lifetime. This requires a considerable amount of energy production by the cells. You would expect to see a relatively large amount of which organelle in the cells?

Mitochondria

A red blood cell placed in pure water would ____________.

Swell and burst

One of the descriptions below is from a perspective of anatomical study, the rest are from a physiological perspective. Select the description below that comes from an anatomical perspective.

The innermost lining of the lungs is composed primarily of a thin tissue called simple squamous epithelium

Phospholipids make up most of the liquid part of the cell membrane. Since water exist on both the outside and inside of a cell, which of the following phospholipid arrangements make the most sense?
