goblet

stratified epithelial tissue

more than one layer of cells

mucus

simple epithelial tissue

one layer thick, involves absorption, secretion, or filtration processes

Found in the urinary bladder, ________ epithelium resembles ________ epithelium, but the apical cells are rounded, not flattened.

transitional; stratified squamous

Under the microscope, which cell type is visible in a tendon slide?

Fibroblast

Cilia are most likely to be seen on which of the following epithelia?

Pseudostratified columnar epithelia

stratified columnar epithelium

1. Also very limited distribution in body\ 2. Small amounts found in pharynx, in male urethra, and lining some glandular ducts 3. Usually occurs at transition areas between two other types of epithelia 4. Only apical layer is columnar

Transitional Epithelium

1. Forms lining of hollow urinary organs 2. Basal layer cells are cuboidal or columnar 3. Able to stretch -> increased flow of urine and, allowing bladder to expand to store urine

simple cuboidal epithelium

1. Function: secretion and absorption 2. Location: Kidney tubules; ducts and secretory portions of small glands, ovary surface. 3. single layer of cube shaped cells 4. often with microvilli or cilia on apical side

stratified squamous epithelium

1. Most widespread of stratified epithelia 2. Found in areas experiencing wear and tear 3. Free surface is squamous, with deeper cuboidal or columnar layers

stratified cuboidal epithelium

1. Quite rare 2. Found in some sweat and mammary glands 3. Typically only two cell layers thick

What are the 4 types of Stratified Epithelia Tissue

1. Stratified squamous - keratinized and unkeratinized 2. Stratified cuboidal 3. Stratified columnar 4. Transitional

4 types of simple Epithelial Tissue

1. simple squamous 2. simple cuboidal 3. simple columnar 4. pseudostratified columnar epithelium

Pseudostratified columnar epithelium

1. single layer of cells of differing heights, some not reaching the free surface. 2. often with goblet cells and cilia 3. Involved in secretion, particularly of mucus, and also in movement of mucus via ciliary sweeping action 4. Location: Ciliated: Lines the trachea and most of the upper respiratory tract. Nonciliated: Sperm-carrying ducts and ducts of large glands

Simple squamous epithelium

1. single layer of flattened cells 2. Location: Kidney glomeruli; air sacs of lungs; lining of heart, blood vessels, and lymphatic vessels; serous membranes of ventral cavity

Which of the following tissues are avascular?

Epithelial tissue and cartilage

Simple columnar epithelium

Function: Absorption; secretion of mucus, enzymes, and other substances; ciliated type propels mucus (or reproductive cells) by ciliated action. Location: nonciliated: lines most of the digestive tract (stomach to rectum). Ciliated: lines small bronchi and uterine (fallopian) tubes

Which tissue forms the stroma of the spleen and lymph nodes?

Reticular tissue
