Question 4

Which connective tissue type is most likely to be found in tendons, and what is its primary function?

Accepted Answer

Dense regular connective tissue; resists pulling forces in one direction

Question 5

During mitosis, which phase is characterized by the alignment of chromosomes along the cell's equator?

Accepted Answer

Metaphase

Question 6

A neuron is damaged in a car accident. Which cell type in the nervous system is most responsible for supporting and protecting neurons?

Accepted Answer

Neuroglia

Question 7

Which of the following best describes the organization of the epidermis?

Accepted Answer

It is composed of multiple layers of stratified squamous epithelial cells.

Question 8

A biopsy reveals a tissue with cells arranged in a single layer, all touching the basement membrane, and specialized for absorption. Which epithelial type is this?

Accepted Answer

Simple columnar epithelium

Question 9

Which of the following is a function of the subcutaneous layer (hypodermis)?

Accepted Answer

Stores energy in the form of fat

Question 10

A muscle cell is observed to contract and relax repeatedly. Which organelle is most directly responsible for producing the ATP required for this activity?

Accepted Answer

Mitochondria

Question 11

Which of the following best explains why stratified squamous epithelium is found lining the esophagus?

Accepted Answer

It provides protection against abrasion from food particles.

Question 12

A patient with a genetic disorder has defective collagen fibers in their connective tissue. Which function is most likely impaired?

Accepted Answer

Structural support and tensile strength

Question 13

Which of the following correctly matches a muscle tissue type with its function?

Accepted Answer

Cardiac muscle; pumping blood throughout the body

Question 14

Which of the following best describes the role of the cytoplasm in a cell?

Accepted Answer

It is the site for most cellular metabolic reactions.

Question 15

A patient is diagnosed with a disease affecting the serous membranes. Which organ system is most likely to be impacted?

Accepted Answer

Cardiovascular system

Question 16

Which of the following is a correct application of anatomical directional terminology?

Accepted Answer

The stomach is inferior to the diaphragm.

Question 17

A histological slide shows cells with abundant rough endoplasmic reticulum. What is the most likely function of these cells?

Accepted Answer

Secretion of proteins

Question 18

Which of the following best differentiates neurons from neuroglia?

Accepted Answer

Neurons conduct electrical impulses; neuroglia support and protect neurons.

Question 19

Which of the following is a correct summary of the cell cycle?

Accepted Answer

The cell cycle includes interphase, mitosis, and cytokinesis.

Question 20

A patient has a mutation that prevents the formation of tight junctions in epithelial cells. Which consequence is most likely?

Accepted Answer

Increased permeability between cells, leading to leakage of substances
