25.  ______cloudy saliva - phlegm

26.  ______clear appearance

27.  ______means “group”

28.  ______functional unit of salivary gland tissue – looks like cluster of grapes – secrete saliva into duct

29.  ______saliva produced daily (amount)

30.  ______attached to acinus of gland

31.  ______connected to intercalated duct.  Passageway for saliva, removes & adds ions to saliva

32.  ______located in connective tissue of gland & saliva.  Will exit directly into oral cavity by this gland

36.  ______etiology of mucocele

37.  ______retention of saliva occurs in submandibular salivary gland in floor of mouth

38.  ______etiology of ranula

39.  ______largest endocrine gland - ductless

40.  ______thyroid gland secretes  ________ which stimulates metabolic rate

41.  ______4-8 small endocrine glands which regulate calcium balance

42.  ______tissue fluid that does not contain RBC but contains lymphocytes & leukocytes with antibodies

43.  ______foreign matter can be removed from lymph and digested by cells of ____________

44.  ______swell and painful when cleaning out foreign matter – cannot fell when healthy

60.  ______grooves found on newly erupted anterior teeth, usually reduce by age

61.  ______dark and light bands that run perpendicular to DEJ, caused by curvature of enamel rods

62.  ______line that marks change in environment and nutrition at birth

63.  ______these lines are found on all primary teeth and larger cusps of permanent first molars

64.  ______come from DEJ where dentinal tubules will penetrate the membrane into enamel

65.  ______come from DEJ and extend outward into the enamel.  Have spaces between enamel rods
