Big Bertha wants a permanent tattoo on her buttocks. How can this be done so it never wears off? Answer: By making sure the needle goes all the way down to the dermis. The dermis is below the epidermis. The epidermis is constantly getting sloughed off and replaced by new skin. A tattoo on the epidermis would only take about 30 days before it was completely wiped off. The dermis is protected from this sloughing off, and would trap the tattoo pigment, making it permanent.

The police find a strand of hair at the crime scene. They determine that the hair belonged to a person that used anti-depressants regularly. How could they do this? Answer: Drugs enter the circulatory system and are carried all over the body. Some of this blood travels up to the hair follicles. The blood in the hair follicle can actually grow into developing hair, carrying traces of the drugs in the system with it.

Bocephus is a nurse. He is being trained on how to conduct an intake session. What could he tell about a person's health by observing the integument? Answer: If a person has blue lips or fingers (cyanosis), he knows there is some internal problem. If the nurse notices yellowing skin (jaundice), he knows there is some issue with the liver filtering out bile. If he notices inflammation of the papillary layer (dermatitis), he know it could be an infection from a bug bite or injury. Could spot bruises or hematomas to locate spots of injury. Vitiligo- could tell if a person's melanocytes are being attacked.

Mary Lou lost 20 pounds in three weeks using a "quick weight loss program". She came off the program and within a week had regained 10 pounds. Explain this. Answer: You cannot lose adipocytes. You lose weight when they shrink, but they are always present. Mary Lou ate healthy and the adipocytes shrank. She came off the diet, and the adipocytes swelled up to a very large size, causing her to rapidly gain weight. The adipocytes were used to healthy food, and as soon as she came off of it, her cells couldn't handle it and swelled up again.

Jethro is not feeling well. Constant fatigue and a low grade fever are his symptoms. He goes to Dr. Doolittle and he immediately orders his blood to be drawn. Why? Answer: Blood is made up of a number of cells. He is looking for signs of infection. Dr. Doolittle is looking for antigens and foreign particles in the circulatory system that could be causing the infection. He could also be looking at the number of leukocytes, for if there is too few, fighting infection is a problem.

Bernice gives birth to her son 6 weeks early. They immediately put him in an incubator. Why? Answer: 6 weeks premature means that the baby's connective tissue is not well developed. There is no subcutaneous fat. Baby is put in heated incubator to help him maintain his body temperature. Without the subcutaneous fat, it is hard to regulate and maintain body temperature. They may also have humidity inside the temperature as an additional source of heat as well as a preventative measure to decrease water losses and skin breakdown.

Geronimo weighs 350 pounds. He has decided to have liposuction. The doctor has to explain the dangers of this procedure. What could Geronimo expect to hear? Answer: After the procedure, the danger of gaining even more weight is possible. The adipocytes in the adipose tissue never go away. Once Geronimo is skinny, he will think it's safe to eat whatever he wants. This can cause the adipocytes to rapidly swell, causing rapid weight gain and health problems. Liposuction of the abdomen can result in the loss of a layer of protection and shock absorption, which can lead to the damage of vital organs. Most importantly, when cutting the fat out, surgeons could hit or puncture an organ, causing a great deal of damage, or hit a major artery, causing Geronimo to bleed out.

June Bell is in nursing school. Today's lecture is on the importance of the intake session. This is where the nurse sees the patient, takes vital statistics, and asks what is wrong, if anything. Now in the session what type(s) of anatomy would June Bell use and why. What could this session tell June Bell? Answer: June Bell is studying gross anatomy, which can be seen on the outside. Specifically, it is surface gross anatomy that June would need to look at things on the outside, such the appearance of her hair, if her skin is clammy or waxen, the dilation of her eyes. If her eyes are bloodshot, she could be on drugs. If her hair is thinning, she might have cancer. If she is limping, her hip might be injured. If her lips and fingers are blue (cyanosis), there is some internal problem. If she is flushed and has pink cheeks, she could have a fever.

Jericho wants to know why simple squamous epithelium is not found in the mouth like it is found lining the alveoli of the lungs. Answer: Simple squamous epithelial is found lining the lungs and not in the mouth because it is very thin and fragile, unlike the thick, tougher tissue that is needed for the inside of the mouth.

You want to be a pharmacist. You are required to take several histology classes. One of this is on epithelial tissue. What is the relationship between this tissue and administering drugs to help cure someone? Answer: Epithelial tissue is made of different shapes of cells, and different layers of tissue. It is important to understand epithelial tissue so you can know how much medication to put into body, how to get it inside, etc. For example, if you understand histology, you know that a lot of epithelial tissue is made up of several, tough layers. If you inject medicine, you would need to know where the layers are thinnest, or amount of pressure to apply to the syringe. You also know that epithelial tissue is made up of lots of tightly interwoven cells, so you would need to supply enough fluid medicine to move across/through gap junctions. You can get medicine transdermally, so you need to know to apply a lot in areas of stratified tissue. Number of layers directly influences how...
