Which of the following statements is TRUE regarding loose connective tissue? a. reticular tissue is the most abundant type of connective tissue found everywhere in the body i. correct = areolar tissue is the most abundant b. epithelial tissue draws its blood supply from areolar tissue c. adipose tissue is absent in the brain, heart, lungs, and eyelids Which of the following statements is FALSE regarding loose connective tissue? a. areolar tissue is avascular b. reticular tissue forms a structural framework called a stroma around soft organs c. adipose tissue gives shape to the body Which of the following statements is TRUE regarding dense connective tissue? a. dense regular connective tissue contains a small amount of fibroblasts b. dense regular connective tissue provides strength in one direction c. dense irregular connective tissue provides strength in multiple directions Which of the following statements is FALSE regarding dense connective tissue? a. dense regular connective tissue contains a small amount of fibroblasts b. an example of dense irregular connective tissue is the dermis c. an example of dense regular connective tissue is a tendon What types of tissue fibers are present in cartilage? a. collagen b. reticular c. elastic Explain why the sensation of pain can be felt in cartilage when there is no direct nerve supply. Pain can be detected in cartilage because of the inflammation that occurs around the tissue Match the type of cartilage with the correct description hyaline cartilage - perichondrium lacking around articular cartilage; abundant in the fetal skeleton elastic cartilage - cells always surrounded by perichondrium; present in the auditory tube fibrocartilage - found in the pubic symphysis; present in the intervertebral discs Which of the following statements is FALSE regarding bone tissue? a. bone tissue is comprised of few fibers with a solid matrix arranged in cylinders called osteons b. the haversian canal functions to bring blood into the bone tissue c. lacunae contain osteocytes d. all are TRUE Name the formed elements found in blood erythrocytes, leukocytes, thrombocytes Match each image with the correct description 1. C. gives epithelial tissue its blood supply
