Question 3

A histology slide shows a single layer of flat cells lining the alveoli of the lungs. Which tissue type is this, and what is one of its primary functions?

Accepted Answer

Simple squamous epithelium; rapid diffusion of gases

Question 4

Which of the following statements about epithelial tissue is correct?

Accepted Answer

Epithelial tissue is avascular but innervated.

Question 5

A tissue sample contains chondrocytes within lacunae and a glassy, smooth matrix. Which tissue is this, and where is it commonly found?

Accepted Answer

Hyaline cartilage; trachea

Question 6

Which connective tissue type is specialized for energy storage and insulation, and what is its primary cell type?

Accepted Answer

Adipose connective tissue; adipocytes

Question 7

Which of the following muscle tissues is both striated and involuntary, and what unique feature does it possess?

Accepted Answer

Cardiac muscle; intercalated discs

Question 8

A slide of nervous tissue shows large cells with prominent cell bodies, branching processes, and smaller supporting cells. Which structures are the dendrites, and what is the function of neuroglia?

Accepted Answer

Dendrites are the branching processes; neuroglia support and protect neurons.

Question 9

During which phase of the cell cycle does DNA replication occur, and what is the significance of this process?

Accepted Answer

S phase of interphase; ensures each daughter cell receives an identical set of chromosomes

Question 10

A tissue sample from the aorta shows abundant elastic fibers and fibroblasts. Which connective tissue is this, and what is its primary function?

Accepted Answer

Elastic connective tissue; allows recoil after stretching

Question 11

Which of the following best describes the difference between the parietal and visceral layers of serous membranes?

Accepted Answer

The parietal layer lines the cavity wall, while the visceral layer covers the organ surface.

Question 12

Which of the following is a function of simple columnar epithelium found in the small intestine?

Accepted Answer

Absorption of nutrients

Question 13

A patient suffers a deep cut on the anterior surface of the antebrachial region. Which area of the body is affected?

Accepted Answer

Front of the forearm

Question 14

Which of the following best describes the arrangement and function of dense regular connective tissue?

Accepted Answer

Parallel collagen fibers; resists tension in one direction

Question 15

Which phase of mitosis is characterized by the alignment of chromosomes along the metaphase plate, and what is the significance of this arrangement?

Accepted Answer

Metaphase; ensures equal separation of chromosomes

Question 16

Which of the following is true regarding the vascularity and innervation of connective tissues?

Accepted Answer

Most connective tissues are vascular and innervated, except cartilage which is avascular and not innervated.

Question 17

Which of the following best describes the function of canaliculi in bone tissue?

Accepted Answer

They allow communication and nutrient exchange between osteocytes.

Question 18

A tissue sample from the trachea shows ciliated cells and mucus-producing goblet cells. Which tissue is this, and what is a primary function?

Accepted Answer

Pseudostratified ciliated columnar epithelium; trapping and moving particles out of the airway

Question 19

Which of the following best describes the difference between mitosis and cytokinesis?

Accepted Answer

Mitosis divides the nucleus; cytokinesis divides the cytoplasm.

Question 20

Which of the following is a correct pairing of a connective tissue cell type and its function?

Accepted Answer

Erythrocytes; transport oxygen in blood
