SECTION 1: INTRODUCTION
This study guide provides a comprehensive, fully verified exam for BIOL251 – Human
Anatomy & Physiology I with Lab, Module 2, designed for the 2025 academic year. The
material covers high-yield topics commonly tested in exams and laboratory assessments,
ensuring students can thoroughly review core concepts and prepare effectively for quizzes,
exams, and practicals.
Key Topics Covered in Module 2:
• Cell structure and function – Understanding organelles, cytoskeleton, and membrane
dynamics.
• Tissues and histology – Epithelial, connective, muscle, and nervous tissue organization.
• Integumentary system – Layers of skin, accessory structures, and protective functions.
• Skeletal system – Bone anatomy, bone cells, cartilage types, and joint classifications.
• Muscular system – Muscle fiber structure, sarcomere function, contraction mechanisms.
Nervous system – Neuron structure, signal conduction, neurotransmitters, and
reflexes.
Section 2
1. What is the basic structural and functional unit of all living
organisms?
A. Tissue
B. Organ
C. Cell
,D. Organ system
SELECTED CORRECT 100% answer: C
Rationale: The cell is the smallest unit capable of performing all life
functions, making it the fundamental unit of structure and function in
organisms.
2. Which organelle is responsible for producing ATP through cellular
respiration?
A. Nucleus
B. Ribosome
C. Mitochondrion
D. Endoplasmic reticulum
SELECTED CORRECT 100% answer: C
Rationale: Mitochondria convert glucose and oxygen into ATP, the energy
currency of the cell, via aerobic respiration.
3. Which of the following is a component of the cytoskeleton?
A. Microtubules
B. Ribosomes
C. Microfilaments
D. Lysosomes
SELECTED CORRECT 100% answer: C
Rationale: The cytoskeleton is made of microfilaments, intermediate
filaments, and microtubules, providing structure, support, and intracellular
transport.
,4. The plasma membrane is primarily composed of:
A. Proteins and nucleic acids
B. Carbohydrates and proteins
C. Phospholipids and proteins
D. DNA and RNA
SELECTED CORRECT 100% answer: C
Rationale: The plasma membrane consists of a phospholipid bilayer with
embedded proteins that regulate transport, signaling, and cell recognition.
5. Which type of tissue covers body surfaces and lines cavities?
A. Connective tissue
B. Epithelial tissue
C. Muscle tissue
D. Nervous tissue
SELECTED CORRECT 100% answer: B
Rationale: Epithelial tissue forms protective layers covering organs, body
surfaces, and lining cavities, and is involved in absorption, secretion, and
filtration.
6. What type of epithelial tissue is found in areas subject to friction,
such as the skin?
A. Simple squamous
, B. Simple cuboidal
C. Stratified squamous
D. Transitional
SELECTED CORRECT 100% answer: C
Rationale: Stratified squamous epithelium has multiple layers, providing
protection against mechanical stress and abrasion.
7. Which connective tissue connects muscles to bones?
A. Ligament
B. Cartilage
C. Tendon
D. Adipose tissue
SELECTED CORRECT 100% answer: C
Rationale: Tendons are strong, fibrous connective tissues that attach
muscles to bones, transmitting force for movement.
8. What type of cartilage is found in the trachea and nose?
A. Fibrocartilage
B. Hyaline cartilage
C. Elastic cartilage
D. Articular cartilage
SELECTED CORRECT 100% answer: B
