Human Tissues
Ch. 4
Objectives
• Classify and state the defining characteristics of epithelial tissue, connective tissue, muscle tissue, and nervous tissue.
• Describe the anatomy and histology of bone tissue.
Epithelial Tissue
• Covers exposed surfaces
• Lines internal passageways and chambers
• Forms glands
Classes of Epithelia
• Based on shape and layers
Absorption,
secretion, &
filtration
Protection
Simple Squamous Epithelia
Simple Cuboidal Epithelia
Simple Columnar Epithelia
Stratified Squamous Epithelia
Pseudostratified ciliated columnar epithelia
Connective Tissue
• Connect epithelium to the rest of the body
• Provide structure (bone)
• Store energy (fat)
• Transport materials (blood)
Connective Tissue
6 Types• Loose connective tissue
• Dense connective tissue
• Adipose
• Blood
• Cartilage
• Bone
Loose Connective Tissue
Areolar C.T.
Dense Connective Tissue
Fibrous C.T.
Adipose Tissue
Blood
Blood smear
Cartilage
Cartilage types
• Hyaline
• Elastic
• Fibrocartilage
Hyaline
Elastic
Fibrous
Bone
Nerve Tissue
• Specialized for conducting electrical impulses
• Rapidly senses internal or external environment
• Processes information and controls responses
Nerve Tissue
Muscle Tissue
3 types of muscle tissue:
• Cardiac –heart
• Skeletal – attached to bones
• Smooth – internal organs and blood vessels
Cardiac Muscle
Skeletal Muscle
Smooth Muscle
