The artery which originates from the abdominal aorta and divides into the left gastric, splenic, and common hepatic arteries. image
CEPHALIC VEIN:
Originates from the dorsal venous arch in the hand and joins the axillary vein. image
CEREBELLAR TONSIL:
A paramedian portion of the cerebellum that is continuous with the uvula of vermis that forms part of the candal lobe of the cerebellar hemisphere. image
CEREBELLUM:
The portion of the metencephalon which occupies the posterior cranial fossa, and is responsible for the coordination of movements. image
CEREBRAL HEMISPHERE:
Pair of rounded structures on either side of the midline of the brain that are partially separated by the longitudinal (interhemispheric) cerebral fissure. image
CERVICAL FASCIA:
image
CERVICAL SPINE:
Vertebral column of the neck. image
CERVIX:
The lower end portion of the uterus connecting the isthmus and the ostium uteri with the vaginal canal. image
CHOROID:
The vascular membrane between the sclera and the retina of the eye, that extends from the ora serrata to the optic nerve. image
CHOROID PLEXUS:
A highly vascular secretory tissue, found within the ventricular system of the brain, responsible for secreting CSF (cerebrospinal fluid). image
CIRCLE OF WILLIS:
The polygonal (hexagon/pentagon) anastomosis that is made up of the internal carotid, anterior and posterior cerebral arteries, the anterior communicating artery, and the posterior communicating arteries - all in the region of the suprasellar cistern. image
CIRCUMFLEX ARTERY:
CISTERNA CHYLI:
The dilated protion of the thoracic duct (a lymphatic channel) in the lumbar region that recieves fluid from the intestinal, lumbar, and descending intercostal lymph vessels. image
CLAVICLE:
The "collar bone". A curved bone which articulates medially with the sternum and laterall with the scapula, forming the anterior portion of the shoulder girdle. image
CLIVUS:
A triangular bone, that slopes upward from the foramen magnum to the dorsum sellae, in the posterior cranial fossa. ( clivus = "wedge" or "slide") image
COCCYX:
The "tail bone" - a caudal extremity of the vertebral column formed by the fussion of four rudimentary vertebrae. image
COCHLEA:
A spiral bone tube of the inner ear, which lies against the lateral end of the internal acoustic meatus. The cochlea ("snail") contains the auditory sensory structure. image
COMMUNICATING VEINS:
Veins found in the thigh, lower leg, and foot that connect superficial and deep veins. image
CORACOID PROCESS:
A projection of bone that originates from the upper part of the neck of the scapula and overhangs the shoulder joint. image
CORONAL VIEW:
Longitudinal section passing through the body at right angles to the median plane, in a "frontal" orientation. image
CORONARY ARTERIES:
The arteries which originate from the root of the ascending aorta and supply the cardiac musckle of the atria and ventricles with blood. image
CORONARY SINUS:
The end portion of the cardiac vein which empties into the right atrium. image
CORPUS COLLOSUM:
A large bundle of white matter, found in the longitudinal fissure, forming a "commissure" by interconnecting the two cerebral hemispheres. image
CORTEX:
The outer layer of a body or organ structure. (Like the "cortex" of the kidney or brain.) image
COSTOPHRENIC ANGLE:
Point of junction between the costal and diaphragmatic pleurae. image
COSTOPHRENIC SULCUS (RECESS):
The space, or potential space, between the ribs ("costo-") of the lateral chest wall and the diagphragm ("phrenic"). image
CRANIAL NERVES(7/8):
The twelve pairs of "nerves" that are directly connected to the brain. They are the nervi olfactorii(I), opticus(II), oculomotorius(III), trochlearis(IV), trigeminus(V), abducens(VI), facialis(VII),vestibulocochlearis(VIII),glossopharyngeus(IX), vagus(X), accessorius(XI),and hypoglossus(XIII). The olfactory "nerve" and the optic "nerve" are actually post-synaptic tracts with glial cells like astrocytes and oligodendrocytes, rather than Schwann cells. image
CRICOID CARTILAGE:
The cartilage that forms the lower and back portion of the larynx, just above the trachea. image
CRISTA GALLI:
The ridge (rooster's comb) that projects upward from the cribriform plate of the ethmoid bone and is attached to the inferior margin of the falx cerebri. image
CRUCIATE LIGAMENTS:
The "cross-shaped" ligaments situated in the knee joint between the femoral condyles and the proximal tibia (tibial spines) that form a cross-shaped structure. image
CT:
Computerized tomography. An imaging device that uses computation to produce an image from multiple individual measurements. image
CUBOID:
A cube-shaped bone in the foot. image
CUL-DE-SAC:
A blind pouch. image
CUNEIFORMS:
A wedged-shaped bone in the foot. image
CRUS OF DIAPHRAGM:
The fibromuscular bands originating from the upper three or four lumbar vertebrae and inserting into the central tendon of the diaphragm. CT 2
CSF(cerebro-spinal fluid):
This is the fluid that surrounds and protects the brain and spinal cord. It is made primarily by the choroid plexus and is absorbed by the arachnoid villi and granulations of the dural sinuses and veins. image
CYSTIC DUCT:
The connection between the neck of the gallbladder and the common bile duct. image
CYSTOGRAM:
A radiograph of the bladder opacified (filled by contrast). image
