Document Summary

Location: air sac (alveoli) of lungs; walls of capillaries; linings of blood vessels and ventral body cavity. Location: surface of ovaries; linings of kidney tubules; linings of ducts of certain glands: simple cuboidal epithelium. Description: single layer; cube-shaped cells: simple columnar epithelium. Description: single layer; elongated narrow cells; some ciliated: pseudostratified columnar epithelium. Description: single layer; elongated cells; some cells do not reach free surface; often. Location: linings of uterus, stomach, gallbladder and intestines ciliated. Function: protection; secretion; movement of mucus and substances. Location: linings of oral cavity, esophagus, vagina and anal canal: stratified squamous epithelium (nonkeratinized) Description: many layers; surface cells flattened and remain alive: stratified squamous epithelium (keratinized) Description: many layers; surface cells dead and keratinized: stratified cuboidal epithelium. Description; 2 to 3 layers; cube-shaped cells. Location: linings of larger ducts of mammary glands, sweat glands, salivary glands and pancreas: stratified columnar epithelium. Description: superficial layer of elongated cells; basal layers of cube-shaped cells: transitional epithelium.

Build a dichotomous key to all the tissues you have seen in the lab. For this, you can use any of their morphological characteristics (under the microscope) but not their physiological functions.

Tissues used in lab : hyaline cartilage, simple squamous epithelium, goblet cells, areolar tissue spread, bone ground, neuron motor nerve cell, adipose tissue, pseudostratified ciliated columnar epithelium, skeletal muscle, stratified squamous epithelium nonkeratinizing, blood, fibrocartilage, transitional epithelium, elastic cartilage, simple cuboidal epithelium, smooth muscle, simple columnar

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 patientâs history further, you notice they have been diagnosed with cystic fibrosis. Essentially, their mucus is thick and very âstickyâ 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 patientâs inability to absorb digested nutrients and secrete watery mucus.

Simple squamous

Stratified squamous

Simple columnar

Transitional

Simple cuboidal
