Explanation The accessory nerve is the eleventh cranial nerve that supplies the trapezius and sternocleidomastoid muscle. The accessory nerve doesn't begin or end in the orbit. This nerve first innervates the sternocleidomastoid before running over posterior cervical triangle for innervating the trapezius. Accessory nerve fibers originate solely in neuron that is present in upper spinal cord. It travels through jugular foramen with vagus and glossopharyngeal nerve...

After you feel comfortable with your counting method and identifying cells in the various stages of mitosis, use the four images below of whitefish blastula to count the cells in each stage until you reach 100 total cells, recording your data below in Data Table 1. (You may not need to use all four images. Stop counting when you reach 100 total cells.) After totaling the cells in each stage, calculate the percent of cells in each stage. (Divide total of stage by overall total of 100 and then multiply by 100 to obtain percentage.) Data Table 1Stage Totals PercentInterphase Mitosis: Prophase Metaphase Anaphase Telophase Cytokinesis Totals 100 100% To find the length of time whitefish blastula cells spend in each stage, multiply the percent (recorded as a decimal, in other words take the percent number and divide by 100) by 24 hours.
