While explaining to a post–surgical knee client about the various forms and function of connective tissue, the nurse gives the example of the client's surgical repair of a torn anterior cruciate ligament (ACL), which is due to:

Question

A) A reticular fiber problem that interrupted the framework for capillaries
B) A dense regular connective tissue tear that is usually rich in collagen fibers that allows ligaments to join bone to bone
C) An irregular, dense connective tissue tear of loose connective tissue that is located in the perichondrium
D) Irregular filling of spaces between tissues to facilitate keeping of joints and tendons in their proper place

Answer 1

Ans: B
Feedback:
Dense regular connective tissues are rich in collagen fibers and form the tendons and aponeuroses that join muscles to bone or other muscles and the ligaments that join bone to bone. Dense irregular connective tissue consists of the same components found in loose connective tissue but exhibits a predominance of collagen fibers and fewer cells. This type of tissue can be found in the fibrous sheaths of cartilage (i.e., perichondrium) and bone (i.e., periosteum). Fibroblasts, the most abundant loose connective tissue cells, synthesize the gel-like substance and collagen, elastin, and reticular fibers. Reticular fibers provide a fibrous framework for capillaries. Adipose tissue helps to fill spaces between tissues and keep organs in place.
