Question

two types of bone tissue
__________ bone- wall of the diaphysis
__________ cancellous bone - epiphysis.
microscopic structure
*bone tissue is called ___________________ tissue.

• the matrix is composed of collagen and inorganic salts

what is collagen?
where is it found?

• osteocytes (mature bone cells)
• enclosed in tiny chambers called ___________________
• these form rings called ___________________ around a haversian canal
• ___________________ (canaliculus) connect the osteocytes

image of bone microscopic structure with blank labels
bone development and growth:
bones first form as hyaline cartilage, then gradually change into bone tissue

• a process called ___________________

primary ossification center -, increases diameter
secondary ossification center - increases length

Explanation:

The problem is about bone tissue structure and development, which falls under Biology (a subfield of Natural Science). For the fill - in - the - blanks:

1. The two types of bone tissue: Compact bone (wall of diaphysis) and Cancellous (spongy) bone (epiphysis).
2. Bone tissue is called osseous tissue.
3. Collagen is a fibrous protein, found in connective tissues (including bone, cartilage, tendons, ligaments).
4. Osteocytes are enclosed in lacunae.
5. The rings around Haversian canal are lamellae.
6. Canaliculi (plural of canaliculus) connect osteocytes.
7. The process of cartilage turning to bone is ossification (endochondral ossification for this type).

For the diagram (assuming typical bone histology diagram labels):

• The central canal is Haversian canal.
• The rings are lamellae.
• The small spaces with osteocytes are lacunae.
• The tiny channels are canaliculi.
• The structures with blood vessels etc. are related to Haversian system components.

Answer:

1. Two Types of Bone Tissue:

• Compact bone - wall of the diaphysis
• Cancellous (Spongy) bone - epiphysis

1. Microscopic Structure:

• Bone tissue is called osseous tissue.
• Collagen: A fibrous protein; Found in connective tissues (bone, cartilage, tendons, ligaments, etc.)
• Osteocytes enclosed in lacunae
• Rings called lamellae around a Haversian canal
• Canaliculi (canaliculus) connect the osteocytes

1. Bone Development and Growth:

• Process: Ossification (Endochondral Ossification)

(Diagram labels - typical answers based on bone histology: Haversian Canal, Lamellae, Lacunae, Canaliculi, Osteocyte (in lacuna), etc. - exact labels depend on diagram's specific parts)
