BIOL123 Lecture Notes - Lecture 15: Epithelium, Connective Tissue, Nephron

1..Some ducts are formed by two layers of cells. In one duct, the apical cell (closest to the lumen, adluminal) are "taller than wide" and the basal cells (farther from lumen, abluminal) are "as tall as they are wide" Another way to describe this epithelium would be to state:

Simple columnar epithelium

Stratified squamous epithelium

Simple squamous epithelium

Simple transitional epithelium

Simple cuboidal epithelium

Stratified cuboidal epithelium

Stratified columnar epithelium

2..Acne (e.g. Acne vulgaris) accounts for approximately 10-15% of all dermatological appointments. This disease is commonly caused by bacterial overgrowth on secreted 'oil.' This disease is related to oil glands which are:(SELECT ANY STATEMENTS THAT ARE APPROPRIATE.)

exocrine glands

ceruminous glands

sebaceous glands

endocrine glands

sudoriferous glands

3. You see a patient complaining of coughing and they report a history of pneumonia. Reading the patient’s history further, you notice they have been diagnosed with cystic fibrosis. Essentially, their mucus is thick and very “sticky” because they can not secrete adequate water with the mucus. Since many areas of the body produce sticky mucus, you expect _______ (epithelia) to be the primary tissue involved with the patient’s inability to absorb digested nutrients and secrete watery mucus.

Simple squamous

Stratified squamous

Simple columnar

Transitional

Simple cuboidal
