organ /or·gan/ (or´gan) a somewhat independent body part that performs a special function.

end organ,
organ of Corti the organ lying against the basilar membrane in the cochlear duct, containing special sensory receptors for hearing, and consisting of neuroepithelial hair cells and several types of supporting cells. Called also spiral o. 
)
Detail of the organ of Corti (spiral organ) in the cochlear duct in the inner ear.
effector organ effector (2).
end organ end-organ.
enamel organ a process of epithelium forming a cap over a dental papilla and developing into the enamel.
genital organs reproductive o's.
Golgi tendon organ any of the mechanoreceptors arranged in series with muscle in the tendons of mammalian muscles, being the receptors for stimuli responsible for the lengthening reaction.
Jacobson's organ vomeronasal o.
reproductive organs the various internal and external organs that are concerned with reproduction.
rudimentary organ
1. a primordium.
2. an imperfectly or incompletely developed organ.
sense organs , sensory organs organs that receive stimuli that give rise to sensations, i.e., organs that translate certain forms of energy into nerve impulses that are perceived as special sensations.
spiral organ o. of Corti.
vestigial organ an undeveloped organ that, in the embryo or in some ancestor, was well developed and functional.
vomeronasal organ a small sac just above the vomeronasal cartilage; rudimentary in adult humans but well developed in many other animals.
Weber's organ prostatic utricle.
organs of Zuckerkandl para-aortic bodies.
| end organ n. The encapsulated termination of a sensory nerve. |
organ [or´gan]
accessory digestive o's (accessory o's of digestive system) organs and structures not part of the alimentary canal that aid in digestion; they include the teeth, salivary glands, liver, gallbladder, and pancreas.
organ of Corti the organ lying against the basilar membrane in the cochlear duct, containing special sensory receptors for hearing, and consisting of neuroepithelial hair cells and several types of supporting cells.
effector organ a muscle or gland that contracts or secretes, respectively, in direct response to nerve impulses.
enamel organ a process of epithelium forming a cap over a dental papilla and developing into the enamel.
end organ end-organ.
Golgi tendon organ any of the mechanoreceptors arranged in series with muscle in the tendons of mammalian muscles, being the receptor for stimuli responsible for the lengthening reaction.
reproductive o's see reproductive organs, female and reproductive organs, male.
sense o's (sensory o's) organs that receive stimuli that give rise to sensations, i.e., organs that translate certain forms of energy into nerve impulses that are perceived as special sensations.
spiral organ organ of Corti.
target organ the organ affected by a particular hormone.
vestigial organ an undeveloped organ that, in the embryo or in some remote ancestor, was well developed and functional.
o's of Zuckerkandl para-aortic bodies.
end organ,
n the expanded termination of a nerve fiber in muscle, skin, mucous membrane, or other structure.
end organ, proprioceptor,
n.pl the sensory end organs, located mainly in the muscles, tendons, and labyrinth, that provide information on the movements and position of the body. Four specific end organs are the muscle spindles; Golgi corpuscles, stimulated by tension; Pacini's corpuscles, stimulated by pressure; and bare nerve endings, stimulated by pain.
end organ, sensory,
n the sensory nerve fibers that end peripherally as either unmyelinated fibers or special structures called receptors. Receptors are situated in the skin, mucous membranes, muscles, tendons, joints, and other structures and also in such special sense organs as those for vision, hearing, smell, and taste. The receptors are organized into a system that relates them to the environment: exteroceptors, interoceptors, and proprioceptors.
end organ
one of the larger, encapsulated endings of sensory nerves.
