Document Summary

Exclusively found within the hypodermis formed by a single layer of pyramidal cell. Between the pyramidal cells and the bm exists a ring of myoepithelial cells that can contract, causing sweat to be pushed up from the lumen through the duct to surface. Pyramidal cells stain and pink and pale the myoepithelial cells stain only slightly darker: excretory duct. Sweat gland: a simple, coiled, tubular gland, simple refers to the fact that every secretory portion has a found in the dermis and epidermis formed by about 2 layers of cuboidal epithelium. More acidophilic and darker than secretory portion. Do not contribute in secretion, just convey sweat upwards. Hair layers of hair follicle from outside in: connective tissue sheath. Stain well with eosin: glassy membrane. Modified bm that is very thick and visible. Extends from epidermal bm: external root sheath (ers) Begin columnar but gradually get more polygonal (continuous with epithelium) Do not stain well; appear pale: internal root sheath (irs)

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.)

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
