Accepted Answer

Parallel bundles of collagen fibers

Question 8

Which of the following best distinguishes cardiac muscle from skeletal muscle under the microscope?

Accepted Answer

Cardiac muscle cells are branched and connected by intercalated discs

Question 9

Accepted Answer

$$n \u003e f$$

Question 10

A histology slide shows a tissue with elongated, spindle-shaped cells, no visible striations, and a single central nucleus per cell. Which tissue is this, and where is it commonly found?

Accepted Answer

Smooth muscle; walls of digestive tract

Question 11

Accepted Answer

Support and protect neurons

Question 12

Which of the following cell types is responsible for producing the fibers found in connective tissue matrix?

Accepted Answer

Fibroblast

Question 13

A tissue sample contains many erythrocytes suspended in a liquid matrix. Which tissue is this, and what is the name of its matrix?

Accepted Answer

Blood; plasma

Question 14

Which of the following connective tissues contains the highest proportion of elastic fibers, and what is its primary function?

Accepted Answer

Elastic cartilage; provides flexible support

Question 15

Which of the following best describes the difference between keratinized and non-keratinized stratified squamous epithelium?

Accepted Answer

Keratinized has a layer of dead, waterproof cells at the surface; non-keratinized does not

Question 16

Accepted Answer

$$V_{gs} = n_f 	imes v_f$$

Question 17

Which of the following best explains why dense irregular connective tissue is well-suited to the dermis of the skin?

Accepted Answer

It contains randomly arranged collagen fibers that resist tension in multiple directions

Question 18

Which of the following is a correct pairing of a connective tissue cell type and the fiber it produces?

Accepted Answer

Fibroblast – collagen fiber
