Which of the following tissues is primarily involved in the detection and response to stimuli?

What is the function of connective tissue in the human body?

Which type of junction is responsible for forming impermeable barriers between cells?

Tissues Overview

A tissue is a group of cells from a common progenitor that work together for a specific function.
Four main tissue types in the human body: Epithelial, Connective, Muscular, and Nervous.
The scientific study of tissues is known as histology.

Epithelial Tissue Functions

Covers and protects body surfaces and lines hollow organs.
Forms various glands in the body.
Specializes in exchanges with the internal and external environment.

Connective Tissue Functions

Provides protection and support to the body and its internal organs.
Connects organs together and serves as a storage site for energy.
Plays a role in aiding the immune system.

Muscular Tissue Functions

Comprised of specialized cells that contract to create force.
Responsible for generating body heat through muscle activity.

Nervous Tissue Functions

Detects stimuli and responds accordingly.
Generates electrical signals, known as nerve impulses, to induce changes in muscle or gland activities.

Cell Junctions

Cell junctions are important contact points between adjacent cells within a tissue.
Five main types of cell junctions include:
- Tight junctions
- Adherens junctions
- Desmosomes
- Hemidesmosomes
- Gap junctions
