What are the arrangements of epithelial cells common in the body?

There are many arrangements of epithelial cells such as squamous, cuboidal, and columnar that organize as simple, stratified, pseudostratified, and transitional. Epithelial cells form from ectoderm, mesoderm, and endoderm, which explains why epithelia line body cavities and cover most of the body and organ surfaces.

What type of epithelium is more than one layer thick?


What is the thickest epithelial tissue?

Keratinized stratified squamous epithelium makes up our epidermis, the outer layer of skin. It is thickest on our palms and soles of our feet. It protects underlying tissue.

What is epithelial tissue BYJU’s?

Epithelial Tissue & Connective Tissue : Animal Tissue. In animals and plants, cells are grouped together to form tissues. These tissues vary in their structure, function, and origin. Types of animal tissue include epithelial tissue and connective tissue, and their structure and functions in animals are discussed below.

What is epithelial and connective tissue?

epithelial and connective tissue is that epithelial tissue lines. the cavity and the surfaces of organs and blood vessels throughout the animal body whereas connective tissue. supports, connects and separates different types of tissues and organs in the body.

What are the similarities between epithelial and connective tissue?

Epithelial tissue is avascular with no blood supply. Connective tissue is vascular and thus are rich in blood vessels, except for cartilages and tendons. Epithelial tissue also doesn’t have nerve supplies. Connective tissue is innervated except for cartilage.
