A quiz that goes over some questions that we discussed over our chapter 5 unit. The test is quite basic for the most part, it refreshes students over most of the main concepts that we went over. It should not come off as too challenging because it is review for to get ready for the final exam.

Questions and Answers

1.

The study of tissues (microscopic anatomy) is known as
- A.
  
  Hematology
- B.
  
  Arthrology
- C.
  
  Histology
- D.
  
  Pathology
Correct Answer
C. Histology

Explanation
Histology is the correct answer because it is the study of tissues, specifically the microscopic anatomy of cells and tissues. Hematology is the study of blood, Arthrology is the study of joints, and Pathology is the study of diseases. None of these options are related to the study of tissues, so they are not the correct answer.

True or False: Epithelia are avascular
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Epithelia are avascular because they lack blood vessels. Epithelial tissues are composed of tightly packed cells that form a protective barrier or lining on the body's surfaces or organs. Nutrients and oxygen are obtained through diffusion from nearby blood vessels in the underlying connective tissue. However, the epithelial cells themselves do not have direct blood supply. This avascularity allows epithelia to efficiently regulate the exchange of substances between different body compartments and maintain their barrier function.

Which of the following is not a result of atrophy?
- A.
  
  Old age
- B.
  
  Lack of muscular use
- C.
  
  ALS (Lou Gehrig s Disease)
- D.
  
  Over use of muscles
Correct Answer
D. Over use of muscles

Explanation
Atrophy refers to the shrinking or wasting away of a body part or tissue due to a decrease in its size or function. It is commonly caused by factors such as old age, lack of muscular use, and certain medical conditions like ALS (Lou Gehrig's Disease). However, overuse of muscles does not lead to atrophy. In fact, overuse can lead to muscle hypertrophy, which is an increase in muscle size and strength. Therefore, overuse of muscles is not a result of atrophy.

Epithelium that reaches the basement membrane in a cell is called?
- A.
  
  Stratified epithelium
- B.
  
  Transitional epithelium
- C.
  
  Simple epithelium
- D.
  
  Stratified squamous epithelium
Correct Answer
C. Simple epithelium

Explanation
Epithelium that reaches the basement membrane in a cell is called simple epithelium. Simple epithelium consists of a single layer of cells that are in direct contact with the basement membrane. This type of epithelium is found in areas where absorption and diffusion are important, such as the lining of the intestines and blood vessels. It provides a thin barrier for the exchange of substances between the body and its external environment. Stratified epithelium, transitional epithelium, and stratified squamous epithelium consist of multiple layers of cells and do not reach the basement membrane.

What are osseous tissues main functions?
- A.
  
  Tightly bind bones together and resist stress
- B.
  
  Breathing, body movements, facial expression
- C.
  
  Physical support of the body/reservoir of calcium and phosphorus
- D.
  
  Forms framework for Lymphatic organs
Correct Answer
C. Physical support of the body/reservoir of calcium and phosphorus

Explanation
Osseous tissue, also known as bone tissue, has two main functions. Firstly, it provides physical support to the body, giving it structure and allowing movement. Secondly, it serves as a reservoir for calcium and phosphorus, which are important minerals for various bodily functions.

True or False: Leukocytes or white blood cells are the most abundant in our blood
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
The correct answer is False. While leukocytes or white blood cells are an important component of our blood, they are not the most abundant. Red blood cells, also known as erythrocytes, are actually the most abundant cells in our blood. They are responsible for carrying oxygen to the body's tissues.

Where is dense regular connective tissue located?
- A.
  
  Tendons and Ligaments
- B.
  
  Deeper portion of dermis
- C.
  
  Lymph nodes
- D.
  
  Surrounding blood vessels
Correct Answer
A. Tendons and Ligaments

Explanation
Dense regular connective tissue is located in tendons and ligaments. Tendons connect muscles to bones, while ligaments connect bones to other bones. Both tendons and ligaments require strong and flexible tissue to withstand the forces exerted on them during movement. Dense regular connective tissue provides this strength and flexibility, making it the ideal location for such tissues.

Which of the following secretes ovarian hormones and produces sperm?
- A.
  
  Transitional epithelium
- B.
  
  Pseudostratified epithelium
- C.
  
  Stratified Squamous epithelium, keratinized
- D.
  
  Stratified Cuboidal epithelium
Correct Answer
D. Stratified Cuboidal epithelium

Explanation
Stratified cuboidal epithelium is the correct answer because it is found in the lining of the seminiferous tubules in the testes, where it produces sperm. It is also found in the lining of the ovarian follicles in the ovaries, where it secretes ovarian hormones. Transitional epithelium lines the urinary bladder and allows for stretching, but does not secrete ovarian hormones or produce sperm. Pseudostratified epithelium lines the respiratory tract and does not secrete ovarian hormones or produce sperm. Stratified squamous epithelium, keratinized, is found in the skin and does not secrete ovarian hormones or produce sperm.

True or False: The most widespread epithelium in the body is simple squamous epithelium
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
The most widespread epithelium in the body is actually simple columnar epithelium. This type of epithelium is found in the lining of the digestive tract, where it helps with absorption and secretion. Simple squamous epithelium, on the other hand, is a single layer of flat cells that is found in areas where diffusion and filtration occur, such as the lining of blood vessels and the air sacs of the lungs. While simple squamous epithelium is important, it is not as widespread as simple columnar epithelium.
