• densely packed fibers,primarily collagen, arranged parallel to each other with nuclei of the fibroblasts also aligned parallel.
• location:tendons, most ligaments, aponeuroses

Question 16

Answer 16

elastic connective tissue: aorta

• connective tissue with densely packed elastic fibers. notice appearance of dark staining elastic fibers. Here these fibers are within the smooth muscle layer of the wall of the aorta.
• location:found within body wall of arteries; throughout trachea and bronchial tree; located within some ligaments in the neck region

Question 17

Answer 17

hyaline cartilage connective tissue:trachea

• cartilage cells(chonodrocytes) located within spaces in the tissue matrix
• forms most of the embryonic skeleton, covers teh ends of long bones in joint cavities forms the costal cartilages, the cartilages of nose, trachea and bronchial tree and most laryngeal cartilages

Question 18

Answer 18

elastic cartilage connective tissue:epiglottis and external ear

• as in hyaline cartilage, the chondrocytes sit in spaces(lacunae) within the tissue matrix
• dark purple strands

Question 19

Answer 19

fibrocartilage connective tissue:tendon

• gelatinous matrix densely pacekd with thick collagen fibers
• form the intervertebral discs, pubic symphysis, articular discs, tendons

Question 20

Answer 20

compact bone connective tissue

• tissue composed of a hard, calcified matrix contianing many collagen fibers
• found in the shaft of long bones, the external portion of flat short and irregular shaped bones, and the externl portion of the epiphyses

Question 21

Answer 21

spongy bone

• composed of the same material as compact bone
• arranged into small beams of bony tissue
• located in interal regions of epiphyses, as well in the internal potins of flat, short, and irregular shaped bones
