Caudad

   Toward the feet (or, in embryology, toward the tail), as opposed to cranial. The spinal cord is caudad to the brain.

RELATED TERMS
--------------------------------------

Feet
The plural of foot, both an anatomic structure and a unit of measure. As an anatomic structure, the foot is the end of the leg on which a person normally stands and walks. The foot is a particularly complex structure made up of dozens of bones that work together with muscles and tendons to execute precise movements. The bones of the foot include the 10 metatarsal bones and the 28 phalanges (toe bones).

Embryology
The study of the development of an organism during the embryonic and fetal stages of life.

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

Cord
1. In anatomy, a long ropelike structure. 2. Short for the spinal cord or the umbilical cord.

Caudad
Toward the feet (or, in embryology, toward the tail), as opposed to cranial. The spinal cord is caudad 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
--------------------------------------

Cauda equina
A bundle of spinal nerve roots that arise from the bottom end of the spinal cord. The cauda equina comprises the roots of all the spinal nerve roots below the level of the first lumbar (L1) vertebra, namely the sacral and coccygeal nerves. So named because it resembles the tail (Latin, cauda) of a horse (Latin, equus). See also Cauda equina syndrome.

Cauda equina syndrome
Neurogenic claudication, resembling intermittent (arterial) claudication. Results from narrowing of the spinal canal (spinal stenosis).

Caudal
The anatomical term for towards the tail. i.e. the kidney is caudal to the shoulder. See Cranial/Superior/Inferior

Caudal anesthesia
Anesthesia produced by injection of a local anesthetic into the caudal canal, the sacral portion of the spinal canal. Caudal anesthesia is used to provide anesthesia and analgesia (pain relief) below the umbilicus. It may be the sole anesthetic or combined with general anesthesia. Also called caudal epidural anesthesia or a caudal block.

Caudate nucleus
In each hemisphere of the brain, the most medial of the four basal ganglia, partly responsible for body movement and coordination. So named because it looks anatomically tail-like.



PREVIOUS AND NEXT TERMS
--------------------------------------

Catheter, Swan-Ganz
A thin, flexible tube that is inserted through one of the large veins (the inferior or superior vena cava) that return blood to the heart. The catheter is flow-directed. It uses a balloon to carry it through the vena cava to the heart, through the right side of the heart (the right atrium and right ventricle) to the pulmonary artery. Once there, the catheter is purposely positioned in a small branch of the pulmonary artery. Then a pressure called the pulmonary wedge pressure is measured in front of the temporarily inflated and wedged balloon.

Catheterization, venous
The insertion of a tiny tube (a catheter) into a peripheral or central vein to deliver fluids or medication. This is the most frequently used method for the administration of intravenous (IV) fluids and IV meds (medications).

Cancer, Hodgkin disease (adult)
A type of lymphoma (cancer of the lymphatic system). The most common symptom of Hodgkin disease is a painless swelling in the lymph nodes in the neck, underarm, or groin. Hodgkin disease is diagnosed when abnormal tissue is detected by a pathologist after a biopsy of an enlarged lymph node. Treatment usually includes radiation therapy or chemotherapy. Regular follow-up examinations are important after treatment for Hodgkin disease. Patients treated for Hodgkin disease have an increased risk of developing other types of cancer later in life, especially leukemia.

Cation
In chemistry, a positively charged ion. A cation is as opposed to an anion, which is a negatively charged ion.

Cauda equina
A bundle of spinal nerve roots that arise from the bottom end of the spinal cord. The cauda equina comprises the roots of all the spinal nerve roots below the level of the first lumbar (L1) vertebra, namely the sacral and coccygeal nerves. So named because it resembles the tail (Latin, cauda) of a horse (Latin, equus). See also Cauda equina syndrome.

Caul
In obstetrics, the caul is the amnion, one of the two fetal membranes, the other being the chorion. To be born in a caul meant to be born with the head covered by the amnion (or be born within an intact unruptured amnion). To be born in a caul was long believed to be a sign of future greatness.

Cauliflower-ear deformity
Destruction of the underlying cartilage framework of the outer ear (pinnae), usually caused by either infection or trauma, resulting in a thickening of the ear. Classically, blood collects (hematoma) between the ear cartilage and the skin. There is a marked thickening of the entire ear which may be so extensive that the shape of the ear becomes unrecognizable. The ear is said to look like a piece of cauliflower. It is typically seen in wrestlers and boxers who have had repeated trauma to the ear.

Caulophyllum thalictroides
Blue cohosh.
