Tissue Types

1
Tissue Types

• For Human Anatomy

2
Four Major Tissue Types

• Epithelial .. Covers body surfaces
• Connective.. Connects tissues
• Muscular. Contracts
• Nervous..Conducts signals

3
Epithelial

• Two major types
• 1. covering and lining epithelium
• Outer layer of skin
• Lines cavities, blood vessels, and organs
• 2. glandular epithelium
• Creates glands

4
Epithelial Functions

• Protection
• Absorption
• Filtration
• Excretion
• Secretion
• Sensory reception

5
Connective Tissue

• Found everywhere in the body
• Made of cells within a matrix
• Subclasses
• Connective proper
• Cartilage
• Bone
• Blood

6
Connective Tissue Functions

• Binding and support
• Protection
• Insulation
• transportation

7
Muscular Tissue

• Three types
• Skeletal
• Smooth
• cardiac
• Well-vascularized tissue with contractile fibers
• (actin and myosin)

8
Muscular Functions

• Voluntary and involuntary movement and tissue
  contraction

9
Nervous Tissue

• Makes up the brain, spinal cord and peripheral
  nerves
• Two cell types
• Neurons
• Supporting cells

10
Nervous Functions

• Conduct nerve impulses
• Support, insulate, protect neurons
