,1. Which layer of the meninges is the tough, leathery outer layer?
Answer: Dura mater
The text states: 'DURA MATER - strong, white fibrous tissue; ... tough, leathery;
outer layer of the meninges.'
2. Which hormone is primarily responsible for the development of secondary
sex characteristics in females?
Answer: Estrogen
The text says estrogen is responsible for secondary sex characteristics in females.
3. Free nerve endings in the skin are responsible for detecting changes in skin
temperature, such as when the skin becomes warmer.
Answer: False
Free nerve endings in the skin are responsible for detecting changes in
temperature, including warmth. The statement is accurate as free nerve endings
serve as thermoreceptors for sensing temperature variations.
4. What is the primary function of microvilli?
Answer: Increase surface area
Microvilli increase surface area to enhance absorption.
5. Cells of the stomach and pancreas produce and secrete digestive enzymes
through which process?
Answer: Exocytosis
Exocytosis is the process by which cells secrete substances, such as digestive
enzymes, by fusing vesicles with the plasma membrane. Endocytosis,
phagocytosis, and pinocytosis are all processes that bring materials into the cell,
not release them.

,6. In anatomical terms, pronation of the arm involves medial rotation of the
forearm, resulting in the palm facing posteriorly.
Answer: True
Pronation of the arm is indeed medial rotation of the forearm, causing the palm
to face posteriorly (or inferiorly when the arm is flexed). The statement is
accurate.
7. Which of the following are determinants of blood viscosity?
Answer: Both a & b
Blood viscosity is primarily determined by hematocrit and plasma protein
concentration, as both influence the internal friction of blood. The correct answer
is 'Both a & b' because it encompasses both key factors, while the other options
are either incomplete or incorrect.
8. Which of the following best defines osmosis?
Answer: Simple diffusion of water through a semipermeable membrane
The text says: 'Osmosis - Simple diffusion of water. - Highly polar water easily
crosses the plasma membrane. - the diffusion of a solvent through a
semipermeable membrane from a dilute to a more concentrated solution'
9. Which type of membrane lines body cavities that are open to the exterior?
Answer: Mucous
Mucous membranes line cavities that open to the exterior.
10. Which of the following tissue types has the greatest regenerative capacity?
Answer: Epithelial tissue
Epithelial tissues regenerate rapidly.

, 11. What is the lighter-staining region located in the center of the A band in a
sarcomere called?
Answer: H zone
In the center of each A band is a smaller, lighter-staining region called the H
zone.
12. What is the primary responsibility of each cell in the body?
Answer: Homeostasis
Homeostasis is the process by which cells maintain a stable internal environment,
which is essential for survival. While cells do reproduce, produce energy, and
undergo respiration, these are specific functions that contribute to the broader
goal of maintaining homeostasis.
13. Which anatomical approach focuses on studying the body by systems, such
as the cardiovascular, nervous, skeletal, and muscular systems?
Answer: Systemic anatomy
Systemic anatomy examines the body by individual systems (e.g., cardiovascular,
nervous), whereas regional anatomy studies specific regions (e.g., the thorax) and
all systems within that region. Surface anatomy relates to external landmarks,
and gross anatomy is a broader category that includes both systemic and regional
approaches.
14. Which of the following best describes ulnar deviation?
Answer: adduction of the hand at the wrist joint
Ulnar deviation refers to the movement of the hand toward the ulnar side
(medially) at the wrist joint, which is adduction. The other options describe
different wrist movements: abduction (radial deviation), flexion, and extension.
15. What is eversion of the foot?
Answer: rotates plantar surface laterally
Eversion of the foot involves turning the sole outward (laterally), which is
described as rotating the plantar surface laterally. Options B and D describe
inversion, and option C is a less precise but acceptable distractor.
