tissues
|
An aggregation of morphologically similar cells and associated intercellular matter acting together to perform one or more specific functions in the body. There are four basic types of tissue: muscle, nerve, epidermal, and connective
|
|
|
basement membrane
|
A thin, delicate layer of connective tissue underlying the epithelium of many organs. Also called basement lamina.
|
|
|
cuboidal
|
noting or pertaining to the outermost bone of the distal row of tarsal bones.
|
|
|
columnar
|
Having the shape of a column.
Constructed with or having columns. |
|
|
squamous
|
Covered with or formed of scales; scaly.
Resembling a scale or scales; thin and flat like a scale: the squamous cells of the cervix. Of or relating to the thin, platelike part of the temporal bone. |
|
|
mucous membrane
|
a lubricating membrane lining an internal surface or an organ, as the alimentary, respiratory, and genitourinary canals.
|
|
|
collagenous fibers
|
collagenous fibers are made of collagen and consist of bundles of fibrils that are coils of collagen molecules.
|
|
|
reticular fibers
|
reticulin is a histochemical term used to describe a type of structural fibers in some connective tissues which is formed fine meshwork(reticulim) of glycosylated collagen III and other components which show up in certain histochemical meothods.
|
|
|
fibroblasts
|
A cell that gives rise to connective tissue.
|
|
|
macrophages
|
Any of the large phagocytic cells of the reticuloendothelial system.
|
|
|
adipose tissue
|
loose connective tissue in which fat cells accumulate
|
|
|
osteoblasts
|
a bone-forming cell
|
|
|
Haversian systems
|
Bone tissue is composed of repeating, circular units called Haversian systems. Within each Haversian system, there is a central canal where blood vessels and nerves can be found.
|
|
|
neuron
|
a specialized, impulse-conducting cell that is the functional unit of the nervous system, consisting of the cell body and its processes, the axon and dendrites.
|
|
|
mesenteries
|
the membrane, consisting of a double layer of peritoneum, that invests the intestines, attaching them to the posterior wall of the abdomen, maintaining them in position in the abdominal cavity, and supplying them with blood vessels, nerves, and lymphatics, esp. the part of this membrane investing the jejunum and ileum.

|
|
thoracic cavity
|
the cavity in the vertebrate body enclosed by the ribs between the diaphragm and the neck and containing the lungs and heart [syn: chest cavity]
|
|
|
metabolic rate
|
rate of metabolism; the amount of energy expended in a give period
|
|
|
basal metabolic rate
|
the rate at which energy is expended in a basal condition, calculated as calories per hour per square meter of body surface and compared with a normal standard expressed as the percentage above or below the amount of oxygen normally used at rest, −15 to +5 percent being considered normal.
|
|
|
interstitial fluid
|
liquid found between the cells of the body that provides much of the liquid environment of the body
|
|
|
enzymatic hydrolysis
|
enzymatic hydrolysis of biomass was the introduction of simultaneous saccharification and fermentation (SSF), which has recently been improved to include the cofermentation of multiple sugar substrates.
|
|
|
suspension-feeders
|
are animals that feed by straining suspended matter and food particles from water, typically by passing the water over a specialized structure, such as the baleen of baleen whales
|
|
|
intracellular digestion
|
digestion within the cell
|
|
|
extracellular digestion
|
outside the cell
|
|
|
gastrovascular cavity
|
functions in both digestion and the transport of nutrients to all parts of an animal body. Organisms belonging to two major phyla, the Cnidaria and the Platyhelminthes, possess gastrovascular cavities.
|
|
|
alimentary canal
|
a tubular passage functioning in the digestion and absorption of food and the elimination of food residue, beginning at the mouth and terminating at the anus.
|
|
|
peristalsis
|
the progressive wave of contraction and relaxation of a tubular muscular system, esp. the alimentary canal, by which the contents are forced through the system.
|
|
|
sphincters
|
A ringlike muscle that normally maintains constriction of a body passage or orifice and that relaxes as required by normal physiological functioning.
|
|
|
pancreas
|
a gland, situated near the stomach, that secretes a digestive fluid into the intestine through one or more ducts and also secretes the hormone insulin.
|
|
|
pepsin
|
an enzyme, produced in the stomach, that in the presence of hydrochloric acid splits proteins into proteoses and peptones
|
|
|
pyloric sphincter
|
A ring of smooth muscle fibers around the opening of the stomach into the duodenum
