There are four primary types of tissues in adults: epithelial, connective, muscle, and nervous. Each tissue type has specific characteristics and functions:
- Epithelial Tissue: This type covers body surfaces and lines cavities. It plays roles in protection, absorption, secretion, and sensation. - Connective Tissue: Provides support and structure to the body. It includes diverse forms like bone, cartilage, blood, and adipose tissue. - Muscle Tissue: Responsible for movement, there are three types: skeletal, cardiac, and smooth muscle. - Nervous Tissue: Composed of neurons and glial cells, it is essential for transmitting nerve impulses.
