,Question 1
• Question: Which of the following is a primary characteristic of all epithelial tissues?
• Options:
o A) They possess a rich blood supply.
o B) They contain an abundant amount of extracellular matrix.
o C) They are primarily responsible for body movement.
o D) They exhibit polarity, having an apical and a basal surface.
• Correct Answer: D) They exhibit polarity, having an apical and a basal surface.
• Rationale: Epithelial tissues are polar, meaning they always have an upper free surface
exposed to the outside or an internal cavity (apical) and a lower attached border (basal).
They are also completely avascular and rely on diffusion from underlying connective
tissues.
Question 2
• Question: Which type of cartilage forms the embryonic skeleton, covers the ends of long
bones at joints, and reinforces the trachea?
• Options:
o A) Hyaline cartilage
o B) Elastic cartilage
o C) Fibrocartilage
o D) Dense regular connective tissue
• Correct Answer: A) Hyaline cartilage
• Rationale: Hyaline cartilage is the most abundant type of cartilage in the body. It
provides flexible skeletal support and forms a smooth, glassy surface at articular joints to
reduce friction.
Question 3
, • Question: Which muscle tissue is characterized by being striated, generally under
voluntary control, and having cells that are multinucleated?
• Options:
o A) Cardiac muscle
o B) Smooth muscle
o C) Skeletal muscle
o D) Visceral muscle
• Correct Answer: C) Skeletal muscle
• Rationale: Skeletal muscle cells are long, cylindrical, striped (striated), and contain
multiple nuclei. They are attached to the skeleton and operate under conscious,
voluntary control.
Question 4
• Question: In nervous tissue, which type of supporting cell (glial cell) is responsible for
regulating the chemical environment around neurons and recycling neurotransmitters?
• Options:
o A) Microglia
o B) Schwann cells
o C) Ependymal cells
o D) Astrocytes
• Correct Answer: D) Astrocytes
• Rationale: Astrocytes are star-shaped cells in the central nervous system (CNS). They
anchor neurons to blood vessels and regulate the surrounding chemical environment by
mopping up leaked potassium ions and recycling neurotransmitters.
Question 5
• Question: In which layer of the epidermis do you find keratinocytes that are actively
dividing and a high population of melanocytes?
, • Options:
o A) Stratum granulosum
o B) Stratum spinosum
o C) Stratum basale
o D) Stratum lucidum
• Correct Answer: C) Stratum basale
• Rationale: The stratum basale (basal layer) is the deepest layer of the epidermis. It
consists of a single row of stem cells that continuously divide to renew the skin,
alongside melanocytes which produce protective melanin pigment.
Question 6
• Question: Which epidermal cell type functions as a sensory receptor for touch?
• Options:
o A) Melanocyte
o B) Langerhans cell
o C) Keratinocyte
o D) Merkel cell (Tactile cell)
• Correct Answer: D) Merkel cell (Tactile cell)
• Rationale: Merkel cells are located at the epidermal-dermal junction. They link directly
up with sensory nerve endings to act as receptors for light touch.
Question 7
• Question: The papillary layer of the dermis is composed primarily of which type of
tissue?
• Options:
o A) Dense irregular connective tissue
o B) Areolar connective tissue
