Tissues & Bones Flashcards
Name the four main types of Tissues
- Epithelial
- Connective
- Muscle
- Nervous
Name the two types of Epithelial Tissues
- Simple epithelial tissue
- Stratified epithelial tissue
Where are Simple Epithelial Tissues found?
In the heart, blood vessels, lymph vessels and parts of the kidney
Where are Stratifies Epithelial Tissues found?
Keratinised - skin, hair nails
Non Keratinised - lining of mouth, vagina & conjunctiva of the eyes
What is the function of Connective Tissue?
Structural support, protection & insulation of the human body
What are the types of Connective Tissues?
- Fascia
- Cartilage
- Blood
- Bone
What is Fascia?
Loose connective tissue
Where is Fascia found?
It surrounds and interpenetrates all components of the human body
What is the function of Bones?
- Support
- Store minerals
- Blood cell Production
- Protection
- Assisting in movement
- Leverage
What are the types of Bones?
- Flat (sternum)
- Irregular (vertebrae)
- Short (carpals)
- Long (femur)
- Sesamoid (patella)
What is one composed of?
Lamellae (Collagen fibres impregnated with mineral salts) & osteocytes (Osteoblasts & Osteoclasts)
What is the difference between osteoblasts & osteoclasts?
Osteoblasts : immature cells producing the matrix
Osteoclasts : absorb and remove bone matrix
In living bone: Osteoclasts are constantly removing
matrix, and osteoblasts constantly replacing it.
What are the 2 types of bone tissue?
- Compact bone - dense
- Cancellous bone - ‘spongy’
Compact Bone
- found mainly in the shafts of long bones (where a strong
tubular structure is required) - has strength as the lamellae are laid down in concentric
rings
Cancellous bone
- found in the parts of bone where lightness and strength are
required - is light as the lamellae are laid down irregularly to form a
mesh
