1. After a peripheral nerve injury, cells surrounding neurons help maintain the local environment and support repair. To which functional group do these supporting cells belong?
Neuroglia
Fibroblasts
Chondrocytes
Erythrocytes
2. What is the primary role of a neuron's axon?
Receiving most incoming signals at branched extensions
Producing collagen for structural support
Conducting signals away from the cell body
Connecting muscle fibers to tendons
3. A gland releases its product through a duct onto an epithelial surface. How should this gland be classified?
Endocrine
Exocrine
Paracrine
Neuroendocrine
4. A biopsy shows long, cylindrical, striated fibers with multiple nuclei. Which tissue was sampled?
Cardiac muscle tissue
Skeletal muscle tissue
Smooth muscle tissue
Dense regular connective tissue
5. During connective-tissue repair, which cells are chiefly responsible for producing collagen fibers and ground-substance components?
Macrophages
Mast cells
Adipocytes
Fibroblasts
6. A microscope slide from the small intestine shows a single layer of tall cells with microvilli. Which function is this tissue best adapted to perform?
Resisting strong multidirectional tension
Absorbing digested nutrients
Producing voluntary body movement
Conducting rapid electrical impulses
7. A tissue sample from the esophagus has many cell layers, with flattened cells at its exposed surface. Which tissue type is it?
Simple squamous epithelium
Stratified squamous epithelium
Simple cuboidal epithelium
Pseudostratified columnar epithelium
8. Which muscle tissue produces the involuntary contractions that move food through the digestive tract?
Skeletal muscle
Cardiac muscle
Dense irregular connective tissue
Smooth muscle
9. Why does damaged cartilage generally heal more slowly than many other connective tissues?
Its matrix contains no structural proteins
Its cells are exposed on a free surface
It has little or no direct blood supply
It contracts after an injury
10. Branching striated muscle cells are joined by intercalated discs. Where would this tissue normally be found?
In the myocardium of the heart
In the wall of the small intestine
Attached to bones by tendons
In the walls of large arteries only
11. Which proteins form the principal interacting filaments responsible for muscle contraction?
Collagen and elastin
Keratin and laminin
Tubulin and fibrin
Actin and myosin
12. Which epithelium is specialized to change shape as the urinary bladder fills and empties?
Simple cuboidal epithelium
Keratinized stratified squamous epithelium
Transitional epithelium
Pseudostratified ciliated columnar epithelium
13. A tendon must withstand pulling forces primarily along one direction. Which tissue arrangement best supports that function?
A mineralized matrix organized into osteons
Loosely arranged fibers in areolar connective tissue
A fluid matrix containing suspended blood cells
Parallel collagen fibers in dense regular connective tissue
14. Which combination best describes major functions of adipose tissue?
Energy storage, insulation, and cushioning
Mucus movement and surface protection
Impulse conduction and sensory integration
Mineral storage and blood cell formation
15. An epithelial sheet remains attached while separating its cells from underlying connective tissue. Which structure provides this interface?
A basement membrane
A synaptic cleft
A periosteal layer
An intercalated disc
16. Why is blood classified as connective tissue?
It forms tightly packed sheets with little extracellular material
It shortens through interactions between contractile proteins
Its cells are suspended in an extracellular matrix called plasma
It lines internal passageways and body surfaces
