Which of the following statements about the general functions of the nervous system is false?

The three primary functions of the nervous system include sensory, integrative, and motor functions.

The integrative functions of the nervous system are its processing functions.

Sensory stimuli are transmitted on sensory efferent fibers to a sensory receptor.

d. Motor functions are carried out by fibers that carry signals to an effector.

Summary Introduction

To review:

The false statement about the general functions of the nervous system.

a. The three primary functions of the nervous system include sensory, integrative, and motor functions.

b. The integrative functions of the nervous system are its processing functions.

c. Sensory stimuli are transmitted on sensory efferent fibers to a sensory receptor.

d. Motor functions are carried out by fibers that carry signals to an effector.

Introduction:

The nervous system of the body is a complex assembly of nerves and specific cells which carry a signal in the form of electrical or chemical stimulus from one part of the body to the other. The nerve cell, or the neuron, is the basic unit of the nervous system. The structure of the nervous system is classified asperipheral and theCNS (central nervous systems).

Explanation of Solution

a. The statement “The three primary functionsserved by the nervous system are sensory, integrative, and motor functions” is true. The nervous systemperforms multiple tasks simultaneously. These functions can be classified as sensory, motor, or integrative functions.

b. The statement “The integrative functions of this system are basically to be its processing functions” is true because the integrative function involves the analysis and interpretation of the sensory stimulus. Then a suitable response is generated according to the stimulus.

c. The statement “Sensory stimuli are send on sensory efferent fibers to the sensory receptor” is false. The sensory system gathers information from the surroundings and sends it towards the central nervous system for interpretation. The efferentfibers carry the response away from the nervous system. Hence, the correct statement is “The sensory stimuli are transmitted on sensory afferent fibers to a sensory receptor.”

d. The statement “Motor functions are mainly carried out by fibers, which are responsible for carrying the signals to an effector” is true. The signal from the nervous system is sent as an output to different organs, called effectors. These effectors bring out the effects of motor nerves.

Conclusion

Thus, it can be concluded that the statements (a), (b), and (d) are true according to the reasons provided and statement (c) is false.

b) Draw a simple summary diagram displaying the different levels of organisation of the nervous system. Include bullet points under each level to describe the function of that part. The bullet points should specifically include details of the role of that part of nervous system in homeostasis. no pics Question 2 (AC 2.1)
1) Which of the following accurately describes the direction of an impulse moving through a neuron that carries information to the central nervous system (CNS) from the peripheral nervous system (PNS)?a. A sensory (afferent) neuron, impulse moving distally.b. A motor (efferent) neuron, impulse moving proximally.c. A motor (efferent neuron, impulse moving distally.d. A sensory (afferent) neuron, impulse moving proximally.   2) The central nervous system (CNS) is composed ofa. spinal nerves.b. sense receptors.c. the brain and spinal cord.d. nerves of the internal organs.
A laboratory experiment is set up where you have two fully functional nerves properly aligned so that it potentially can transmit an action potential through a synapse to the second nerve. The buffer outside the cells contain Na+, H+ and Cl- as the only inorganic ions. When you stimulate the nerve, surprisingly the second nerve does not respond. What is the most likely explanation for the failure of the second nerve response? State why you chose your answer. a. The lack of K+ in the buffer prevents propagation of the action potential b. Neurotransmitter is not being released into the synaptic space. c. An action potential can only be initiated by opening a ligand-gated channel. d. Although neurotransmitter is released, it is unable to stimulate opening of the second nerve' ligand-gated channel. e. Repolarization of the axon does not occur in this buffer.
