Connective tissue(cartilage)

Question 1

Hyaline cartilage

Answer 1

A). Characteristics: Clumped chondrocytes surrounded by a gelatin-like matrix

B). Locations: between tips of ribs and bones of sternum; covering bone surfaces at synovial joints; supporting larynx, trachea, and bronchi; forming part of nasal septum

C). Functions: provides stiff but somewhat flexible support; reduces friction between bony surfaces

Question 2

Elastic cartilage

Answer 2

A). Characteristics: Short, wavy elastin fibers forming a weblike mesh around clustered chondrocytes.

B). Locations: Auricle of external ear; epiglottis; auditory canal; cuneiform cartilages of larynx

C). Functions: provides support, but tolerates distortion without damage and returns to original shape

Question 3

Fibrous cartilage

Answer 3

A). Characteristics: Small cells, often distributed in rows, situated amid thick, often parallel bundles of collagen fibers.

B). Locations: Pads within knee joint; between pubic bones of pelvis; intervertebral discs

C). Functions: resists compression; prevents bone to bone contact; limits relative movement
