Chapter 42, Problem 7TYU
Summary Introduction
Introduction: Highly developed human brain, along with the spinal cord make up the central nervous system. Main function of the spinal cord is to transmit impulses from the brain to the other parts of the body and from the other parts of the body to the brain. Controlling reflex activities is another function performed by the spinal cord. When an involuntary motor response towards an external stimulus takes place, it is known as a reflex action. When a neural circuit having three types of neurons responds to a stimulus, it is known as withdrawal reflex.

A) Galen correctly identified that peripheral nerves could control bodily function B) Galen correctly identified the division between the central and peripheral nervous systems C) Galen demonstrated that tendons, ligaments and nerves were separate entities D) Galen demonstated that transection of individual nerves had little functional consequence.arrow_forwardNeuroscience Question: Which of the following statements ACCURATELY describe spinal cord organization. α-motor neurons are organized from lateral to media such that those found towards the medial section of the spinal cord controls the distal muscles. Lumbar spinal cord enlargement is observed where neurons that innervate the legs and feet are located Neuronal cell bodies (somas) of neurons that innervate single muscles are only found in a single spinal cord segment. Muscles of the trunk are represented medially while muscles of arms and hands are represented laterally Group of answer choices 1, 2, 4 2, 3, 4 2, 4 4 only 1,2,3,4 Here is my reasoning: Please you be the judge if this is correct! α-motor neurons are organized from lateral to medial such that those found towards the medial section of the spinal cord control the distal muscles. This is inaccurate. α-motor neurons are organized from medial to lateral in the spinal cord, with those medially controlling axial…arrow_forwardWhat evidence led Sherrington to conclude that transmission at a synapse is different from transmission along an axon? a. Chemicals that alter a synapse are different from those that affect action potentials. b. The velocity of a reflex is slower than the velocity of an action potential. c. Stains and microscopic observations demonstrate a gap at the synapse. d. Reflexes can go in either direction, whereas axons transmit in only one direction.arrow_forward

(This should be dated, with a brief explanation of the studies) How do we study neurogenesis in animals? In humans? Where can we find stem cells in the brain? What is so important about these brain structures? (For example: Why do we find excess stem cells in these structures, but not in others?) How can stem cell proliferation be inhibited? How might neurogenesis be related to learning and memory?arrow_forwardThe ability of stronger stimuli to produce wider range of reflex responses depends upon :-a- presence of reverberating circuits in reflex pathwayb- presence of parallel-chain circuits in reflex pathwayc- convergence of interneuronsd- divergence of interneuronsarrow_forward
