Chapter 41, Problem 2TYU
Summary Introduction
Introduction: Neurons are the basic unit of the nervous system that transmits the information. A neuron is the largest cell in the body consisting of the cell body, axon, dendrites, and terminal branches. Nerve impulses that are identified as stimuli are received and then transmitted forward to the CNS and then from CNS to the effectors by the neurons. The axon is covered by a layer of cells called myelin sheath, which helps in the improvement in signal transduction.

(a) voltageactivated Na+ channels open (b) K+ channels open (c) the membrane hyperpolarizes (d) neurotransmitter is released (e) K+ channels closearrow_forwardView the University of Michigan Webscope (http://openstaxcollege.org/l/nervefiber) to see an electron micrograph of a cross-section of a myelinated nerve fiber. The axon contains microtubules and neurofilaments, bounded by a plasma membrane known as the axolemma. Outside the plasma membrane of the axon is the myelin sheath, which is composed of the tightly wrapped plasma membrane of a Schwann cell. What aspects of the cells in this image react with the stain that makes them the deep, dark, black color, such as the multiple layers that are the myelin sheath?arrow_forwardIn temporal summation.. Select one: O A. IPSPS, but not EPSPS, are combined. O B. The postsynaptic cell's potential is a combination of two EPSPS arriving at a synapse in rapid succession. O C. Two synapses on different regions of a cell are stimulated at the same time. O D. A synapse is stimulated a second time after the effect of a first stimulus at the synapse has been terminated. O E. The size of an action potential depends on the size of the stimulus.arrow_forward

Group of answer choices They make a small number of synapses with many GPNs and a large number of synapses with a few GPNs They are GABAergic and therefore inhibitory. They are constitutively active to tonically inhibit the thalamus. They are activated by inputs from the cortex. All of the above are truearrow_forward
- need help question, come up with 1 example in the body for each of the Peripheral Nervous System Pathways. The Somatic and the Visceral Pathway. For each example you need to Identify the receptor (general like in my example below) and then each pathway name, (the afferent pathway, integrator, and efferent pathway.) Then Identify the shape of the neuron for each of the 3 pathways (afferent, integrator & efferent) HINT: Visceral division is the organ (smooth or cardiac muscle) pathway, the Somatic division is the Skeletal Muscle pathway Example Visceral Stretch receptors sense that the bladder is full Viserceral Sensory Division (VSD) sends a message to the brain (Integrator) send message to the bladder smooth muscle to urinated Viseral Motor Division (VMD) The VSD is a unipolar neuron and the Integrator & VMD is a multipolar neuron Somatic Pain receptors sense that we are touching something sharp Somatic Sensory Division (SSD) sends a message to the spinal cord…arrow_forwardWatch this video (http://openstaxcollege.org/l/summation) to learn about summation. The process of converting electrical signals to chemical signals and back requires subtle changes that can result in transient increases or decreases in membrane voltage. To cause a lasting change in the target cell, multiple signals are usually added together, or summated. Does spatial summation have to happen all at once, or can the separate signals arrive on the postsynaptic neuron at slightly different times? Explain your answer.arrow_forwardTest Your Understanding 8. VISUALIZE Label the diagram of the human brain.arrow_forward
