Crypt

CryptIn anatomy, a crypt is variously a blind alley, a tube with no exit, a depression, or a pit -- in an otherwise fairly flat surface.
RELATED TERMS--------------------------------------
Anatomy
The study of form. Gross anatomy involves structures that can be seen with the naked eye. It is as opposed to microscopic anatomy (or histology) which involves structures seen under the microscope.
Crypt
In anatomy, a crypt is variously a blind alley, a tube with no exit, a depression, or a pit -- in an otherwise fairly flat surface.
Blind
1. Unable to see. Without part or all of the sense of sight.2. In a clinical trial, not to know the treatment given or received. The participant is not told whether they are in the experimental or control arm of the study. Also called masked.
Depression
A mental state of depressed mood characterized by feelings of sadness, despair and discouragement. Depression ranges from normal feelings of the blues through dysthymia to major depression. It in many ways resembles the grief and mourning that follow bereavement, there are often feelings of low self esteem, guilt and self reproach, withdrawal from interpersonal contact and physical symptoms such as eating and sleep disturbances.
SIMILAR TERMS--------------------------------------
Cryptic
Hidden. Cryptic tonsillitis is hidden within the depths of the tonsil.
Crypto
Popular name for both the parasite, Cryptosporidium parvum, and the disease it causes, cryptosporidiosis.
Cryptography
"The encoding and decoding of secret messages. Cryptography in genetics: The term ""cryptography"" can be applied to human DNA since the message of life is encoded in DNA. And for eons even the existence of DNA was unknown and the information therein an unfathomed mystery. The decoding of DNA in the human genome project is essentially an exercise in cryptography, the greatest piece of cryptography ever undertaken in human history. However, this cryptographic project is incomplete since, although the sequence of most of the DNA has been determined, we are still far from understanding all of the many messages encoded within it. "
Cryptorchidism
Failure of descent of one or both of the testes into the scrotum. The testes first develop within the abdomen before birth and then normally descend into the scrotum. Cryptorchidism is also called undescended testes. Males with cryptorchidism that is not surgically corrected in early childhood are at increased risk for developing testicular cancer.
Cryptosporidiosis
"An intestinal infection characterized by diarrhea caused by a microscopic parasite, Cryptosporidium parvum. The parasite lives in the small intestine of humans and animals who pass it in their feces. The parasite is protected by an outer shell that allows it to survive outside the body for long periods of time and makes it resistant to chlorine disinfection. Both the disease and the parasite are popularly known as ""Crypto."" The disease is also called cryptosporidium enteritis."
Cryptosporidium parvum
The parasite that causes the disease, cryptosporidiosis.
PREVIOUS AND NEXT TERMS--------------------------------------
Cryoglobulinemia
The presence in blood of abnormal proteins called cryoglobulins that, by definition, have the unusual properties of precipitating from the blood serum when it is chilled and redissolving upon rewarming. (Cryoglobulins are gamma globulins with a molecular weight of approximately 200,000.)
Cryophobia
An abnormal and persistent fear of cold, including cold weather and cold objects. Sufferers from cryophobia experience anxiety even though they realize their fear is irrational. To avoid cold, they may live in a warm climate, dress more warmly than necessary, stay indoors on cold days, and avoid cold foods and ice cubes.
Cryoprobe
A surgical probe, a long slender pointed surgical instrument, used to apply extreme cold to tissues.
Cryoprotectant
A chemical component of a freezing solution used in cryopreservation (the process of cooling and storing cells, tissues, or organs at very low temperatures to maintain viability). The purpose of the cryoprotectant is to help protect what is being frozen from freeze damage.
Cryostat
A chamber that can maintain very low temperatures. Medical laboratories use a cryostat to preserve frozen tissue samples while a microtome, an extremely sharp cutting instrument mounted inside cryostats, slices the tissue into pieces thin enough to be observed under a microscope. The sliced piece must be so thin as to look nearly transparent. A pathologist, a laboratory doctor trained to identify evidence of disease in microscopic structures, then examines the slice to confirm or rule out the presence of a disease, such as cancer. Use of frozen tissue samples enables physicians to examine tissue and diagnose its condition more quickly than if the tissue had been preserved without freezing.
Crypt
Cryptic
Hidden. Cryptic tonsillitis is hidden within the depths of the tonsil.
