ANATOMY

SOME structures are formed by degeneration of other

1. Oblique popliteal ligament: from degeneration of semimembranous muscle

2. Sacrotuberous ligament : from long head of biceps femoris

3. Sacrospinous ligament : from coccygeus

4. Articular disc of TMJ : from lateral pterygoid

5. Fibular collateral ligament : from peroneus longus

6. Tibial collateral ligament : from adductor magnus

7. Median umblical cord : from obliterated urachus

PHYSIO

Skeletal Muscle

1. Actinin : binds actin to Z line

2. Desmin : binds Z line to plasma membrane

3. Titin : binds Z line to M line

Its the largest known protein

Titin contributes to elasticity of muscle

4. Structural and fuctional unit of skeletal muscle is sarcomere

5. Area of sarcomere with only myosin is H zone

6. Band in sarcomere which remain unchanged during skeletal muscle contraction is A band

BIOCHEM

RATE LIMITING ENZYME

1. Glycolysis : phosphofructokinase

2. Gluconeogenesis : PEP(phosphoenol pyruvate) carboxylase

3. Glycogenesis : glycogen synthase

4. Glycogenolysis : glycogen phosphorylase

5. Kreb cycle : isocitrate dehydrogenase

6. Ketone body synthesis : HMG co A synthase

7. Cholesterol synthesis : HMG co A reductase

8. Porphyrin synthesis : ALA synthase

9. Fatty acid synthesis : acetyl CoA carboxylase

10. Uric acid synthesis : xanthine oxidase

MICRO

Important culture media

1. Robertson cooked meat broth : all anaerobic bacteria

2. MacConkey's agar : all enterobacteriacea

3. Bordet gengue medium : bordetella pertussis

4. Skirrow medium : helicobacter pylori

5. Cetrimide agar : pseudomonas

6. PPLO medium : Mycoplasma

7. Selenite F broth and tetrathionate broth : salmonella and shigella

8. Dorset egg medium : mycobacterium TB

9. Sabourauds dextrose agar : fungus , Nocardia
