Chapter 4 Tissue Level of Organization

What are the four major types of tissues in the body?

Epithelial Tissue, Connective Tissue, Muscle Tissue, Nervous Tissue.

What is the study of tissue called?

Histology.

What prevents the passage of water and solutes between cells?

Tight Junctions.

What type of epithelial tissue is composed of a single layer of flat cells?

Simple Squamous Epithelium.

What are the functions of epithelial tissue?

Physical protection, control permeability, provide sensation, and produce specialized secretions.

What is the primary characteristic of connective tissue?

It has an extracellular matrix and is derived from mesenchyme.

What are the components of connective tissue?

Cells and extracellular matrix (fibers + ground substance).

What type of cartilage is the most common?

Hyaline cartilage.

What is the function of adipose tissue?

Provides padding, shock absorption, insulation, and energy storage.

What type of muscle tissue is striated and voluntary?

Skeletal muscle.

Which tissue type is responsible for conducting electrical impulses?

Nervous tissue.

What are the types of secretion methods for exocrine glands?

Merocrine, Apocrine, and Holocrine.

What do neurons do?

Transmit electrical signals.

What is the function of neuroglia in nervous tissue?

Support, protect, and insulate neurons.

What are the three types of muscle tissue?

Skeletal muscle, Cardiac muscle, and Smooth muscle.

Where is transitional epithelium found?

In the urinary system, such as the bladder and ureters.

What is the role of connective tissues in the body?

Establish structural framework, transport fluids, protect organs, store energy, and defend against microorganisms.

What distinguishes stratified squamous epithelium from simple squamous epithelium?

Stratified squamous has multiple layers of cells, while simple squamous has a single layer.
