Study Notes
Tissue Types
- There are 4 main tissue types: epithelial, connective, muscle, and nervous tissue
Epithelial Tissue
- Forms boundaries between different environments
- Secretes, protects, absorbs, and excretes
- Found on skin surface and surrounding glands
- 2 forms: covering and lining epithelium, and glandular epithelium
- Characteristics: polarity, specialized contacts, supported by connective tissue, avascular, and innervated
Connective Tissue
- Supports, anchors, and protects
- Found in bones, tendons, fat, and other soft tissues
- Types of connective tissue: bone, cartilage, adipose, and connective tissue proper
- Components: ground substance, fibers, and cells
Muscle Tissue
- 3 types: skeletal, smooth, and cardiac
- Skeletal muscle: attaches to bone, enables voluntary movement
- Smooth muscle: found in hollow organs, helps move substances through
- Cardiac muscle: found in heart, propels blood throughout body
Nervous Tissue
- Enables internal communication between brain, spinal cord, and nerves
- 2 major cell types: neurons and glial cells
- Neurons: basic unit of nervous system, transmit and process information
- Glial cells: provide support, protection, and maintenance functions
Test your knowledge on the 4 main types of tissues found in the human body: epithelial, connective, muscle, and nervous tissues. Learn about their functions and characteristics.
