### cell | vegetative cell | epithelial cell:

Goblet cell
* More goblet cells are present than in the jejunum and ileum.
* account for more of the epithelial cells than in the small intestine.
* are epithelial cells
  - numerous in intestinal epithelium they are interspersed among the absorptive cells
  - rare or absent and the epithelium appears low columnar
* increase in number from the proximal jejunum to the distal ileum.
* look like a drinking goblet, with the pedestal or base toward the basal side.
* protect the living cells of the alimentary canal from hard rough food and enzymes.
* secrete mucus for protection.

Hair cell
* Most hair cells are part of cochleas.
* are also a type of skin cell
  - extraordinarily sensitive to cilia displacement
  - fast-growing, so the hair falls out during treatment
  - in the inner ear , or cochlea
  - neurons
  - pale orange and non-hair cells are in dark orange
  - sensitive mechanical-stimulus detectors
  - small
* are the hearing mechanoreceptor cells, and they reside in the cochlea
  - receptors in the olfactory epithelium that respond to particular chemicals
  - very sensitive, but they are also very fragile
* begin alive, but when they come out of the scalp, they are dead.
* center around lamia III.
* convert sound waves into electrical impulses that are sent to the brain.
* have projections called stereocilia
  - small hairs called cilia on one side and an axon on the other side
* is an epithelial cell
* move mucus toward the sinus ostia.
* populate the length of the cochlea down the basilar membrane.
* send the sounds, as electrical impulses, to the brain.
* synapse upon dendrites of neurons whose cell bodies are located in the spiral ganglion.
* transform mechanical energy to electrical energy.

Fat cell
* Every fat cell makes estrogen.
* More fat cells produce more estrogen.
* Most fat cells are in the trunk and limbs.
* Some fat cells are in place to help keep the eyes warm.
* are animal cells
  - constantly present in bone marrow
  - examples of specialized cells
  - plentiful and easy to get to
  - present, large and empty of fat in embedded sections
  - somatic cells
  - the body's equivalent of a piggy bank
* are very delicate but many survive the liposuction process
  - efficient about storing fat, but have to be coaxed into letting it go
* develop in tissue grown from preadipocyte cells.
* feast on sugar alcohol and other alchemic surplus clouded by a mushroom.
* function as energy reservoirs.
* have a large capacity to increase in size by storing more fat per cell
  - an almost unlimited storage capacity
* insulate the body from cold and can help protect it from injury.
* lie beneath the skin in virtually all body areas
  - throughout the body accumulate in greater amounts in certain areas
* make leptin, and in general, obese people have more leptin in their bloodstreams.
* manufacture estrogen.
* produce a substance that makes the other cells in the body resistant to insulin
  - estrogen, which lowers the risk of osteoporosis after menopause
* release fats into blood as alternative fuel
  - high density lipoproteins when called upon to do so
* respond by giving up their little lives as they are burned for energy.
* retain estrogen which helps maintain the calcium in the bones.
* seem to increase in number during childhood development.
* take in the fat.
* tend to convert testosterone to estrogen, exacerbating any existing deficiency.
