Question 1. Histology of Elastic Cartilage
Answer:

• Its matrix contains numerous elastic fibres
• These fibres are arranged in a network
• They are viewed using special stains
• The surface of elastic cartilage is covered by perichondrium
• Elastic cartilage is seen in following sites:
  1. Skeletal basis of auricle
  2. Lateral part of external acoustic meatus
  3. Wall of medial part of auditory tube
  4. Epiglottis & two small laryngeal cartilages
  5. Apical part of arytenoid cartilage

Question 2. Histology of Compact Bone
Answer:

• Compact bone is made up of lamella
• These lamellae are arranged in concentric rings surrounding narrow
• Haversian canal
• Canal runs along the length of the bone
• These canals branch & anastomose with each other

• They also communicate with the marrow cavity & with the external surface of bone through channels called the canals of Volkmann
• This canal is occupied by blood vessels, nerve fibres & some cells
• Together Haversian canal & lamellae constitute Haversian system, also called osteon
• Compact bone consists of many such osteons separated by interstitial lamellae
• Near its surface lamellae are arranged parallel to the surface called circumferential lamellae
