Glosary 41 - 50

41. Coccyx (Coxis): commonly referred to as the tailbone, is the final segment of the human vertebral column. Comprising three to five separate or fused vertebrae (the coccygeal vertebrae) below the sacrum, it is attached to the sacrum by a fibrocartilaginous joint, the sacrococcygeal symphysis, which permits limited movement between the sacrum and the coccyx.

42. Cold (Resfriado Común): having a low or inadequate temperature or feeling a sensation of coldness or having been made cold.

43. Dacryocyst (saco lagrimal): the two dilated ends of the lacrimal ducts at the nasal ends of the eyes that fill with tears secreted by the lacrimal glands.

44. Dander (Caspa): is material shed from the body of various animals, similar to dandruff or pet pollen. It may contain scales of dried skin and hair, or feathers. It is a frequent cause of allergy in humans.

45. Deaf (Sordo): Not having the faculty of hearing, or only partially able to hear.

46. Decubitus (Decúbito): Commonly used in medicine, the word decubitus is used to mean "lying down". It originates from the Latin term decumbere meaning "to lie down". The term is related to the Latin cubitum, which means elbow. This is because of the Roman tendency to lean upon their elbows when resting.

47. Deferent Duct (Conducto deferente): also called ductus deferens, (Latin: "carrying-away vessel"), is part of the male anatomy of some species; they transport sperm from the epididymis in anticipation of ejaculation.

48. Defibrillation (Desfibrilación): is the definitive treatment for the life-threatening cardiac arrhythmias, ventricular fibrillation and pulseless ventricular tachycardia. Defibrillation consists of delivering a therapeutic dose of electrical energy to the affected heart with a device called a defibrillator. This depolarizes a critical mass of the heart muscle, terminates the arrhythmia, and allows normal sinus rhythm to be reestablished by the body's natural pacemaker, in the sinoatrial node of the heart.

49. Degenerative disease (Enfermedad degenerativa):is a disease in which the function or structure of the affected tissues or organs will progressively deteriorate over time, whether due to normal bodily wear or lifestyle choices such as exercise or eating habits. Degenerative diseases are often contrasted with infectious diseases.

50. Deltoid Muscle (Músculo deltoides): In human anatomy, the deltoid muscle is the muscle forming the rounded contour of the shoulder.It was previously called the Deltoideus and the name is still used by some anatomists. It is called so because it is in the shape of the Greek letter Delta (triangle).The deltoid is a frequent site to administer intra-muscular injections.
