SECTION 1: Skin Anatomy & Physiology (Questions 1-10)
Q1. During the inflammatory phase of wound healing, which cell type is
the first to migrate into the wound bed to control bacterial
contamination?
• A) Fibroblast
• B) Macrophage
• C) Neutrophil
• D) Lymphocyte
Answer: C – Neutrophils are the first responders, arriving within minutes to
hours post-injury. Their primary role is phagocytosis of bacteria and debris.
Macrophages arrive later (48-72 hours) and are essential for transitioning to
the proliferative phase.
Q2. The process by which macrophages transition from a pro-
inflammatory (M1) phenotype to an anti-inflammatory (M2) phenotype
is essential for:
• A) Hemostasis
• B) Proliferation and remodeling
• C) Eschar formation
• D) Biofilm formation
Answer: B – M1 macrophages dominate early inflammation (phagocytosis).
The shift to M2 phenotype releases growth factors (TGF-beta, VEGF) that
drive fibroblast proliferation, angiogenesis, and eventually
scarring/remodeling. Failure of this switch leads to chronicity.
,Q3. A wound contraction rate of 20% per week is observed in a full-
thickness wound left to heal by secondary intention. What is the
primary cell responsible for this contraction?
• A) Keratinocyte
• B) Neutrophil
• C) Myofibroblast
• D) Adipocyte
Answer: C – Myofibroblasts, containing alpha-smooth muscle actin, exert
contractile forces that pull wound edges together. This process is distinct
from re-epithelialization, which is driven by keratinocytes.
Q4. The dermis is primarily composed of which type of connective
tissue?
• A) Elastic fibers only
• B) Collagen and elastin fibers
• C) Reticular fibers only
• D) Adipose tissue
Answer: B – The dermis is composed of collagen (providing strength) and
elastin (providing elasticity). These fibers are embedded in a ground
substance of proteoglycans and glycosaminoglycans.
Q5. Which layer of the skin contains the stem cells responsible for
epidermal renewal?
• A) Stratum corneum
• B) Stratum granulosum
• C) Stratum basale
, • D) Stratum spinosum
Answer: C – The stratum basale (basal layer) contains keratinocyte stem
cells that divide and differentiate to form the upper epidermal layers. This
layer is responsible for continuous skin renewal and wound re-
epithelialization.
Q6. What is the primary function of the stratum corneum?
• A) Production of melanin
• B) Barrier function against water loss and pathogens
• C) Sensation of touch and pressure
• D) Synthesis of vitamin D
Answer: B – The stratum corneum is the outermost layer of dead,
keratinized cells that forms the primary barrier against water loss and
pathogen entry. This barrier is compromised in wounds and dermatological
conditions.
Q7. Which cell type produces melanin in the skin?
• A) Keratinocytes
• B) Langerhans cells
• C) Melanocytes
• D) Merkel cells
Answer: C – Melanocytes are pigment-producing cells located in the
stratum basale. They produce melanin, which provides UV protection and
determines skin color. Langerhans cells are immune cells, and Merkel cells
are involved in sensation.
Q8. What is the primary function of Langerhans cells in the epidermis?
• A) Production of keratin
