BIOS 252 Anatomy And Physiology II Week 1 To 8 Entire1. The finger-like projections extending from the neuron’s cell body that are most frequently the site of stimulation and formation of graded potentials are called . a. Synaptic Cleft b. Dendrites c. Axon d. Axon Hillock Graded potentials are more often generated by the dendrites. If the graded potentials goes above a certain threshold at the axon Hillock, an action potential is generated and carried down the axon to the terminal e...

Myelination of the nerve fibers in the central nervous system is the job of the oligodendrocyte. T/F -:- True If bacteria invaded the CNS tissue, microglia would migrate to the area to engulf and destroy them. T/F -:- True Neurons in the CNS are organized into functional groups. T/F -:- True Efferent nerve fibers may be described as motor nerve fibers. T/F -:- True Voltage is always measured between two points and may be called the potential between these two points. T/F 2 0 ...

BIO 235 Final Exam Questions With 100% Correct Answers 2024/2025 Potassium: A. is more abundant outside the cell than inside the cell. B. moves into the cell during an action potential. C. is transported out of the neuron by the sodium-potassium pump. D. leaks out of the cell more than sodium leaks into the cell. - answerc. salutary and continuous action potential conduction - answerconduction occurs in myelinated axons.
