Med term chapter 2 part 4

  1. The tissues form a protective covering for all of the internal and external surfaces of the body. They also form glands.
    epithelial tissues
  2. epithelium
    the specialized epithelial tissue that forms the epidermis of the skin and the surface layer of mucous membranes
  3. endothelium
    the specialized epithelial tissue that lines the blood and lymph vessels body cavities glands and organs.
  4. The tissue supports and connects organs and other body tissues.
    connective tissues
  5. what are the four types of connective tissues?
    • dense connective tissues
    • adipose tissue
    • loose connective tissue
    • liquid connective tissues
  6. dense connective tissue
    bone cartilage, forms the joints and framework of the body
  7. adipose tissue (fat)
    provides protective padding insolation and support
  8. adip
  9. -ose
    pertaining to
  10. loose connective tissue
    surrounds various organs and supports both nerve cells and blood vessels
  11. liquid connective tissues
    are blood and lymph transport ntrients and waste products throughout the body
  12. muscle tissue
    contains specialized cells with the ability to contract and relax
  13. nerve tissue
    contains cells with specialized ability to react to stimuli  and conduct electrical impulses
  14. aplasia
    the defective development or the congenital absence of an organ or tissue

    a- = without -plasia= formation
  15. hypoplasia
    the incomplete development of an organ or tissue usually due to a deficiency in the number of cells

    hypo= deficient  -plasia = formation
  16. anaplasia
    • a change in the structure of cells and in their orientation to each other.
    • characteristic of tumor formation in cancers.

    ana- = backward -plasia = formation
  17. dysplasia
    the abnormal development or growth of cells tissues or organs

    dys- = bad - plasia = formation
  18. hyperplasia
    enlargement of an organ or tissue because of an abnormal increase in the number of cells in the tissues.

    hyper= excessive & -plasia = formation
  19. hypertrophy
    a general increase in the bulk of a body part or organ that is due to an increase in the size but not in the number of cells in the tissues. Not due to tumor formation.

    hyper = excessive & trophy=development
  20. gland
    a group of specialized epithelial cells that are capable of producing secretions. 2 types exocrine and endocrine
  21. secretion
    the substance produced by a gland
  22. These glands secrete chemical substances into ducts that lead either to other organs or out of the body.
    exocrine glands

    exo- out of & -crine = to secrete
  23. exo-
    out of
  24. -crine
    to secrete
  25. These glands produce hormones that are secreted directly into the bloodstream and are then transported to organs and structures throughout the body.
    endocrine glands

    endo- = within & -crine = to secrete
  26. endo-
  27. aden
  28. -itis
  29. adenitis
    the inflammation of a gland

    aden = gland &  -itis = inflammation
  30. adenocarcinoma
    a malignant tumor that originates in glandular tissue

    aden/o=gland & carcin = cancerous & -oma = tumor
  31. aden/o
  32. carcin
  33. -oma
  34. malignant
    harmful, capable of spreading and potentially life threatening
  35. adenomalacia
    the abnormal softening of a gland

    aden/o = gland & -malacia = abnormal softening
  36. adenosis
    any disease or condition of a gland

    aden = gland & -osis = abnormal condition or disease
  37. adenosclerosis
    the abnormal hardening of a gland

    adeno- gland & -sclerosis = abnormal hardening
  38. adenectomy
    the surgical removal of a gland

    aden = gland and -ectomy =surgical removal
  39. pathology
    • the study of disease: the nature and cause as well as the produced changes in structure and function
    • OR
    • a condition produced by disease
  40. path/o and - pathy
    disease or suffering, feeling & emotion
  41. pathologist
    specialist who specializes in the laboratory analysis of tissue samples to confirm or establish a diagnosis
  42. etiology
    the study of the causes of diseases

    eti- = means cause & -ology= study of
  43. eti-
  44. pathogen
    a disease producing microorganism such as a virus.
  45. transmission
    spread of a disease
  46. contamination
    possible presence of a pathogen
  47. communicable disease (ontagious disease)
    any condition that is transmitted from one person to another either by direct or by indirect contact
  48. communicable
    capable of being transmitted
  49. indirect contact transmission
    the spread of a disease through contact with blood or other body fluids that are contaminated with blood.
