Accepted Answer

Pacinian corpuscles

Question 13

Which of the following best explains why the epidermis is avascular?

Accepted Answer

Accepted Answer

Epidermal ridges

Question 15

Which of the following is a major difference between connective tissue proper and supporting connective tissue?

Accepted Answer

Supporting connective tissue (cartilage and bone) has a more rigid matrix and fewer cell types

Question 16

Which of the following best describes the function of fibroblasts in connective tissue?

Accepted Answer

Produce collagen and other extracellular matrix components

Question 17

Accepted Answer

$$R = \frac{D}{t}$$

Question 20

Which of the following best describes appositional growth in cartilage?
