Tissues Overview

Tissues are groups of specialized cells that work together to perform specific functions.
There are four basic types of tissue in the human body.

Basic Tissue Types

The four basic tissue types are:
- Epithelial tissue
- Connective tissue
- Muscle tissue
- Nervous tissue

Epithelial Tissue

Epithelial tissue covers both internal and external surfaces and forms continuous sheets without blood vessels.
Classification is based on shape (e.g., squamous, cuboidal, columnar) and arrangement (e.g., simple or stratified).

Connective Tissue

Connective tissue provides structural support and connects different organs and tissues.
It is the most abundant and widely distributed tissue type in the body.
Components of connective tissue include:
- Adipose (fat)
- Dense fibrous tissue
- Bone
- Cartilage
- Blood

Muscle Tissue

Muscle tissue is specialized for movement and has a higher degree of contractility compared to other tissues.
Regeneration of muscle tissue is slow when injured.
Types of muscle tissue include:
- Skeletal (striated and voluntary)
- Smooth (non-striated, involuntary, or visceral)
- Cardiac (striated and involuntary)

Nervous Tissue

Nervous tissue is responsible for rapid communication between body structures and control of body functions.
It primarily consists of nerve cells, also known as neurons.
Neurons have two key components:
- Axons, which transmit nerve impulses away from the cell body
- Dendrites, which carry impulses toward the cell body
