3 (Pro)myelocyte and neutrophilic granulocytes in bone marrow smear (human)Stain: May-Grnwald-Giemsa (MGG). The promyelocyte (1) contains coarse primary, azurophilic granules in the basophilic cytoplasm. The absence of nucleoli indicates the late stage of the promyelocyte. (2) segmented neutrophilic granulocyte with toxic granulation (large irregular granules). (3) indicat...Poja Histology Collection - Blood & Bone Marrow Subset
4 1.0 Biosynthesis of Steroid Hormones - IntroductionA video introduction to the biosynthesis of steroid hormones. Guide questions -- What types of compounds are included in the class of steroids? Why is it important to know the sources and pathways in the synthesis of steroid hormones?

5 1st degree AV blockThe normal PR interval is 0.12 - 0.20 sec, or 120 -to- 200 ms. 1st degree AV block is defined by PR intervals greater than 200 ms. This may be caused by drugs, such as digoxin; excessive vagal tone; ischemia; or intrinsic disease in the AV junction or bundle branch system.Knowledge Weavers ECG

7 2nd degree AV block with junctional escapes and capturesSecond degree AV block is present; conducted beats are identified by those QRS's that terminate shorter cycles than the junctional escape cycle; i.e., the 3rd and probably the 4th QRS's are captures; the other QRS's are junctional escapes.Knowledge Weavers ECG
8 2nd degree AV block, mobitz type II, with LBBBThe wide QRS complexes in lead V1 indicates LBBB. 2nd degree AV block, Mobitz II is suggested by the two fixed PR intervals prior to the nonconducted P wave. The location of the block is most likely in the right bundle, because Mobitz II is usually a sign of bilateral bundle branch disease.Knowledge Weavers ECG
9 2nd degree AV block, type IThe 3 rules of classic AV Wenckebach are: 1. decreasing RR intervals until pause; 2. the pause is less than preceding 2 RR intervals; and 3. the RR interval after the pause is greater than the RR interval just prior to pause. Unfortunately, there are many examples of atypical forms of Wenckebach wh...Wenckebach AV BlockKnowledge Weavers ECG

11 2nd degree AV block, type I with escapes and capturesOften in the setting of 2nd degree AV block the pauses caused by nonconducted P waves are long enough to enable escape pacemakers from the junction or ventricles to take over. This example illustrates junctional escapes, labled E and captures, labled C. Note that the PR intervals for the captures ...Knowledge Weavers ECG
12 2nd degree AV block, type I, with accelerated junctional escapes and a ladder diagramThe ladder diagram illustrates a Wenckebach type AV block by the increasing PR intervals before the blocked P wave. After the blocked P wave, however, a rev-ed up junctional pacemaker terminates the pause. Note that the junctional beats have a slightly different QRS morphology from the sinus beats...Knowledge Weavers ECG
13 2nd degree AV block, type I, with junctional escapesJunctional escapes are passive, protective events whenever the heart rate slows below that of the escape mechanism. In this example of 2nd degree AV block, type I, the escapes occur following the non-conducted P waves. Arrows indicate the position of the P waves. Note that the escape beats have a...Knowledge Weavers ECG
