Chorda tympani
|
|
Chorda tympaniA branch of the facial nerve (the seventh cranial nerve) that serves the taste buds in the front of the tongue, runs through the middle ear, and carries taste messages to the brain.
RELATED TERMS--------------------------------------
Nerve
Tissue that conveys sensation, temperature, position information to the brain.
Cranial
The anatomical term for towards the head; also the general term for of the head. i.e. the lungs are cranial to the pelvis. See Caudal/Inferior/Superior
Tongue
The muscular organ attached to the floor of the mouth. Used to speak, chew, swallow and taste.
Ear
The hearing organ. There are three sections of the ear, according to the anatomy textbooks. They are the outer ear (the part we see along the sides of our head behind the temples), the middle ear, and the inner ear. But in terms of function, the ear has four parts: those three and the brain. Hearing thus involves all parts of the ear as well as the auditory cortex of the brain. The external ear helps concentrate the vibrations of air on the ear drum and make it vibrate. These vibrations are transmitted by a chain of little bones in the middle ear to the inner ear. There they stimulate the fibers of the auditory nerve to transmit impulses to the brain.
Brain
"That part of the central nervous system that is located within the cranium (skull). The brain functions as the primary receiver, organizer and distributor of information for the body. It has two (right and left) halves called ""hemispheres."" "
SIMILAR TERMS--------------------------------------
Chordae Tendinae
The thin, fibrous chords that lead from the valve leaflets to the small papillary muscles within the heart muscle wall, contributes to the support of the tricuspid and mitral valves.
Chordae tendineae
Thread-like bands of fibrous tissue which attach on one end to the edges of the tricuspid and mitral valves of the heart and on the other end to the papillary muscles, small muscles within the heart that serve to anchor the valves.
Chordee
Fixed curvature or tying down of the penis or hypertrophied clitoris as in the hypospadiac birth defect characteristic of various types of hermaphroditism.
Chordoma
A form of bone cancer that usually starts in the lower spinal column.
Chorea
Rapid, jerky, dance-like movement of the body.
Chorioangioma, placental
A benign vascular (blood vessel) tumor of the placenta (afterbirth). Large chorioangiomas cause complications including polyhydramnios (excess amniotic fluid), maternal and fetal clotting problems (coagulopathies), premature delivery, toxemia, fetal heart failure, and hydrops (excess fluid) affecting the fetus.
Choriocarcinoma
A highly malignant tumor that arises from trophoblastic cells within the uterus. Choriocarcinoma tends to be invasive and to metastasize early and widely through both the venous and lymphatic systems. Choriocarcinoma is one of the two types of gestational trophoblastic tumor, the other being hydatidiform mole.
Chorion
The outermost of the two membranes surrounding the embryo/fetus, part of which forms the fetal portion of the placenta.
Chorionic gonadotropin
Human chorionic gonadotropin (hCG) is a peptide hormone produced in pregnancy, that is made by the embryo soon after conception and later by the trophoblast (part of the placenta). Its role is to prevent the demise of the corpus luteum of the ovary and thereby maintain progesterone production that is critical for a pregnancy in humans. hCG may have additional functions, for instance it is thought that it affects the immune tolerance of the pregnancy.
Chorionic villus sampling
A procedure for first-trimester prenatal diagnosis. Chorionic villus sampling may be done between the eighth and tenth weeks of pregnancy. The aim is to diagnose severe abnormalities afflicting the fetus. In the procedure, tissue is withdrawn from the villi (vascular fingers) of the chorion, a part of the placenta, and examined. Chorionic villus sampling is referred to commonly as CVS.
Chorionic Villus Sampling (CVS)
A procedure in which a small sample of cells are taken from the placenta through a small catheter placed up through the vagina and the cervix. This is done earlier in pregnancy than amniocentesis and is used to test for chromosomal and other biochemical abnormalities that may affect the health and well being of the baby.
Chorioretinitis
An inflammation of the back of the eye involving the choroid and retina. It may be due to a number of different diseases, which affect the body such as toxoplasmosis, histoplasmosis, sarcoidosis, tuberculosis and syphilis.
Choroid
This is the vascular coat between the sclera and the retina, which furnishes blood and nutrition to the outer layer of the retina.
Choroideremia
Atrophy or decay of the choroid, choriocapillaris and Bruch’s membrane of the eye, leading to a severe loss of vision. Usually progresses to light perception by 50 years of age. Leads to night blindness tunnel vision and reduced visual acuity. No treatment available.

Cholesterol guidelines
The guidelines on cholesterol for adults.
Cholestin
One of the three major preparations of red yeast rice, a tradition Chinese medicine now used to lower cholesterol. Cholestin is also known as Hypocol.
Chondroitin sulfate
A glycosaminoglycan (formerly called a mucopolysaccharide) found in cartilage, bone, blood vessels and connective tissues. There are two forms: chondroitin sulfate A and chondroitin sulfate C. One or both types accumulate abnormally in several of the mucopolysaccharidosis disorders. Chondroitin sulfate B is now called dermatan sulfate.
Chondroplasia
The formation of cartilage by specialized cells called chondrocytes.
Chondrosarcoma
A malignant tumor that forms in cartilage cells (chondroplasts) and that produces cartilage matrix. Chondrosarcoma can be primary or secondary. Primary chondrosarcoma forms in bone and is found in children. Secondary chondrosarcoma arises from preexisting benign defects of cartilage (such as an osteochondroma or enchondroma), usually after age 40. Treatment is mainly by surgery.
