Document Summary

Sweat gland simple, coiled, tubular gland: contained within an bm, merocrine secretion normal shape) two portions of the gland, secretory portion, cells not histologically modified when they secrete sweat (retain. Exclusively found within the hypodermis formed by single layer of pyramidal cells: pyramidal cells stain pink and pale. Surrounded by myoepithelial cells that can contract (to push sweat up duct: excretory duct, myoepithelial cells stain only slightly darker found in dermis and epidermis. More acidophilic and darker than secretory portion. Small lumens layers of hair follicle from outside in: glassy membrane. Modified bm that is very thick and visible. Extends from epidermal bm: external root sheath (ers) thickest layer. Does not stain well; appears pale: internal root sheath (irs) 3 distinct layers: Cuticle of hair shaft: single layer of squamous cells without visible nuclei, does not stain well. Huxley"s layer: several layers of squamous cells that contain acidophilic. Cuticle of the irs: one layer of pale cells.

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
