Anterior chamber
"The space in the eye that is behind the cornea and in front of the iris. The cornea is the outer, transparent, dome-like structure that covers the iris, pupil, and the anterior chamber. The iris is the colored ring of tissue suspended behind the cornea and immediately in front of the lens; it regulates the amount of light entering the eye by adjusting the size of the pupil. The anterior chamber is filled with a watery fluid known as the aqueous humor, or aqueous. Produced by a structure alongside the lens called the ciliary body, the aqueous passes first into the posterior chamber (between the lens and iris) and then flows forward through the pupil into the anterior chamber of the eye."

Anterior cruciate injury
A knee injury involving the anterior cruciate ligament (ACL). The ACL runs diagonally across the front of the knee from the underside of the femur (the thigh bone) to the top of the tibia (the bigger bone in the lower leg).

Anterior cruciate ligament
ligament in the knee that crosses from the underside of the femur (the thigh bone) to the top of the tibia (the bigger bone in the lower leg). Abbreviated ACL. Injuries to the ACL can occur in a number of situations, including sports, and can be quite serious, requiring surgery.

Anterior pituitary
The front portion of the pituitary, a small gland in the head called the master gland. Hormones secreted by the anterior pituitary influence growth, sexual development, skin pigmentation, thyroid function, and adrenocortical function. These influences are exerted through the effects of pituitary hormones on other endocrine glands except for growth hormone which acts directly on cells. The effects of underfunction of the anterior pituitary include growth retardation (dwarfism) in childhood and a decrease in all other endocrine gland functions normally under the control of the anterior pituitary (except the parathyroid glands). The results of overfunction of the anterior pituitary include overgrowth (gigantism) in children and a condition called acromegaly in adults.

The anthracyclines are frequently used in leukemia therapy. The anthracyclines include daunorubicin (Cerubidine), doxorubicin (Adriamycin, Rubex), epirubicin (Ellence, Pharmorubicin), and idarubicin (Idamycin)."
