BIOL 251 (Anatomy
and Physiology I)
BIOL 251 quires synthesizing fundamental concepts from
human histology, skeletal systems, muscular systems,
and neuroanatomy covered in standard undergraduate
modules.
Below is a complete, structured set of 150 practice questions designed
to reflect the rigorous scope and core curriculum of Portage Learning BIOL
251.
Part 1: Introduction to Anatomy, Physiology,
and Histology (Q1–Q30)
1Q: What is the definition of anatomy?
A: The study of the structure and shape of the body and its parts.
2Q: What is the definition of physiology?
A: The study of how the body and its parts work or function.
3Q: What is homeostasis?
A: The body's ability to maintain relatively stable internal conditions even
though the outside world changes continuously.
,4Q: What is a negative feedback mechanism?
A: A regulatory mechanism in which the net effect is to shut off the original
stimulus or reduce its intensity.
5Q: What is a positive feedback mechanism?
A: A regulatory mechanism that tends to increase the original disturbance
(stimulus) rather than turn it off.
6Q: What anatomical term describes a position where the body is upright,
feet parallel, arms at the sides with palms facing forward?
A: Anatomical position.
7Q: Which directional term means toward or at the front of the body?
A: Anterior (or ventral).
8Q: Which directional term means toward or at the back of the body?
A: Posterior (or dorsal).
9Q: What body plane divides the body into right and left parts?
A: Sagittal plane.
10Q: What plane divides the body into equal right and left halves down the
midline?
A: Midsagittal (median) plane.
11Q: What plane divides the body into superior and inferior parts?
A: Transverse (horizontal) plane.
13Q: What plane divides the body into anterior and posterior parts?
A: Frontal (coronal) plane.
14Q: What are the two major subdivisions of the dorsal body cavity?
A: Cranial cavity and spinal cavity.
15Q: What are the major subdivisions of the ventral body cavity?
A: Thoracic cavity and abdominopelvic cavity.
16Q: What muscle separates the thoracic cavity from the abdominopelvic
cavity?
, A: Diaphragm.
17Q: What are the four primary tissue types found in the human body?
A: Epithelial, connective, muscular, and nervous tissue.
18Q: What is the primary function of epithelial tissue?
A: Protection, absorption, filtration, and secretion.
19Q: How is epithelial tissue classified based on cell layers?
A: Simple (one layer) and stratified (multiple layers).
20Q: What shape describes flattened, tile-like epithelial cells?
A: Squamous.
Q: What shape describes cube-like epithelial cells?
A: Cuboidal.
Q: What shape describes tall, column-like epithelial cells?
A: Columnar.
Q: What type of epithelium lines the air sacs (alveoli) of the lungs and blood
vessels for rapid diffusion?
A: Simple squamous epithelium.
Q: What type of epithelium lines the digestive tract from stomach to anus?
A: Simple columnar epithelium.
Q: What type of stratified epithelium is found in areas subject to considerable
friction, such as the outer layer of skin?
A: Stratified squamous epithelium.
Q: What type of epithelium lines the urinary bladder and stretches?
A: Transitional epithelium.
Q: What is the most abundant and widely distributed tissue type in the body?
A: Connective tissue.
Q: What are the three main components of connective tissue?
A: Ground substance, fibers, and cells.
