USABO Open Exam 2014 Questions And Answers Why is myelin important in the nervous system? A. It allows signals to travel faster along axons because depolarization occurs only at myelinated locations. B. It allows signals to travel faster along axons because depolarization occurs only at unmyelinated locations. C. It bundles the dendrites of adjacent neurons together. D. It increases capacitance across the cell membrane, which helps electrical signals to leave the axons. E. It traps ne...

A muscle's force depends on the total cross-sectional area of all fibers within it that are activated to contract. If maximum force per unit area produced by a muscle (at 100%) is 25 N/mm2, how much force (in Newtons, N) would the muscle produce if it has 1 cm2 in cross-section of actively contracting fibers? 25 N 250 N 2500 N 10 N None of the other answer options are correct. - Answer-2500 N Based on the Results and Follow-up Work sections, which statement is correct? (a) Researchers...

BIOL 266 DETAILED FINAL NOTES| CONCORDIA UNIVERSITY|UPDATED 2024/2025 UNIT 9.0 – THE CYTOSKELETON Two functions of the cytoskeleton: 1. Provides structural framework for the cell,serving as a scaffold that determines cell shape and the general organisation of the cytoplasm. 2. Responsible for the movements of the entire cells and for the internal transport of organelles and other structures (such as mitotic chromosomes) through the cytoplasm. The cytoskeleton is composed of 3 principa...
