Describe what is happening in each phase. a) latent- is a short period between the time of stimulation and the beginning of contraction b). Contraction – at this stage the muscle reaches its peak in contraction. Relaxation -Muscle is shortened‚ returns to zero and back initial length.

Histology analysis There were five steps involved in histological preparation. Step 1: Dissection and tissues collection The testis tissues were cut with a sharp scalpel into slices of not more than 2-3 mm thick and 10 mm long. The fixation process was commenced immediately after removal of the tissue sample. The specimen tube was filled with 20 ml of 10% formalin. The tissue was placed inside the specimen tube. Step 2: Dehydration Dehydration process begins when the fixed tissues was

yield each trial obtained for the CaCO3. Pre-Lab Questions 1. A limiting reagent is one that is used up first out of the reagents that are used. This substance determines how much actual product is made 2. CaCl2: 7.15 g x 1 mol / 111.0 g = 0.06 mol CaCO3 K2CO3: 9.25 g x 1 mol / 138.2 g = 0.07 mol CaCO3 CaCl2 is limiting reagent Theoretical yield = 0.06 mol CaCO3 x 100 = 6.40 g CaCO3 Percent yield = 6.15 g / 6.40 g = 96.1 % Post-Lab Questions 1.

Practical 1 Title: Tissue Processing Aim: To examine human cell and tissue under the microscope Introduction: Tissues from the body taken for analysis of diseases must be processed in the histology laboratory to produce microscopic slides that are viewed under the microscope. These tissues are usually fixed into paraffin. Microscopic analysis of cells and tissues requires the preparation of very thin‚ high quality sections mounted on glass slides and properly stained to demonstrate normal and abnormal
